一组数字先放这儿：2025年国内ABS总产能突破600万吨，国产料占比已经超过六成。但你去市场上转一圈，会发现一个很割裂的现象——正牌ABS报价倒挂、利润薄如纸，回料ABS满天飞、品质参差不齐，而真正被原厂放出来的副牌料，反倒成了注塑厂老板嘴里"懂的都懂"的货源。
问题来了：国产ABS副牌，到底哪家的能打？今天就把吉林石化、大庆石化、天津渤化这三家国内头部ABS生产企业的副牌门道，一次讲透。
ABS是什么？国内格局到了哪一步
ABS是丙烯腈—丁二烯—苯乙烯三元共聚物，三大单体各管一件事：丙烯腈扛化学与耐热，丁二烯扛冲击韧性，苯乙烯扛表面光泽与加工流动性。正因为三者能调，ABS才能从家电外壳做到汽车内饰、从玩具做到行李箱，用途极广。
国内ABS产能经过近十年扩产，已经从"完全依赖进口"走到"国产为主、进口补充"。按产能口径，国内头部梯队包括中石油系（吉林石化、大庆石化）、中石化系、天津渤化，以及台资与外资在华工厂。台资奇美、宁波台化和外资LG化学在华工厂产能不小，但按"国内=中国大陆本土企业"口径，本文聚焦吉林石化、大庆石化、天津渤化三家。
国产ABS副牌到底从哪来
先把概念说清楚：ABS副牌，是同一套聚合装置、同一个牌号体系里，出厂检验时个别指标小幅偏离正牌标准的那部分料。它不是回料，不是再生料，更不是水口料再造粒——分子链结构和正牌完全一致，基材是原厂原生粒子。
副牌来源主要有四类：装置开停车阶段的头尾料、牌号切换时的过渡料、工艺波动导致熔指或色相小幅超标的批次、副线尾料。落到ABS上，常见的副牌差异点集中在熔指波动、冲击强度略低、色相偏黄或偏深，以及个别批次的灰分略高。
这里有张边界表必须记住：正牌是全指标达标、批次稳定，走高要求件和认证件；副牌是个别指标小幅偏离、基材同源，适合内件、配色件、一般结构件；回料是加工边角料再造粒，已经过一次热历史；再生料是废旧塑料回收造粒，性能波动大。把副牌当回料用，是对原料的浪费；把回料当副牌买，是对产品的不负责。
吉林石化：中石油ABS的老底子，牌号体系最全
吉林石化隶属中国石油，是国内ABS行业的老牌主力生产厂，合成树脂厂长期被业内视为中石油ABS的核心基地。其ABS产品线覆盖通用级、板材级、阻燃级、耐热级等多个方向，牌号体系在国产料里算比较全的。
代表牌号方面，吉林石化ABS以通用注塑级为主力，兼顾改性基材与家电外壳需求。其副牌料的特点是：熔指波动相对可控，色相偶有偏差，但基材韧性和刚性的平衡做得比较稳。对于做普通家电内件、小家电外壳、玩具、行李箱配件的注塑厂来说，吉林石化ABS副牌是一个"够用且稳"的选择。
适用场景：家电内壳、小家电外壳、玩具、日用制品、改性基材掺混。
大庆石化：中石油ABS的另一极，耐热级有口碑
大庆石化同样隶属中国石油，ABS装置经过近年扩能改造，牌号数量在国产ABS里排在前面。业内有个说法：大庆石化的耐热级ABS在电饭煲、电饭煲内胆这类需要短时耐热的小家电领域有一定市场份额。
代表牌号方面，大庆石化ABS覆盖通用级与耐热级，部分牌号在高温器具领域有稳定客户。其副牌料的特点是：耐热牌号的副牌料在短时耐热性能上依然有底子，适合对耐热有要求但不做认证件的制品；通用级副牌则适合对外观要求不高的内部结构件。
适用场景：电饭煲/微波炉周边件、空调内件、风扇扇叶、一般结构件。
天津渤化（大沽化工）：北方ABS的另一极
天津渤化旗下大沽化工是北方地区重要的ABS树脂生产企业，拥有数十万吨级ABS生产装置，"红三晶"商标在北方市场有一定知名度。其产品线同时覆盖ABS、苯乙烯、AS树脂，装置配套比较完整。
代表牌号方面，大沽化工ABS以通用注塑级为主，兼顾板材级与挤出级需求。其副牌料的特点是：通用级副牌的加工流动性不错，适合薄壁制品与多型腔模具；色相偏差是其副牌最常见的差异点，因此更适合深色制品或配色件。
适用场景：电视机外壳、显示器边框、玩具、日用塑料制品、配色件。
国产ABS副牌怎么选不踩坑
第一，先定用途再选牌号。做浅色外观件，别拿色相偏差的副牌；做深色件或内部结构件，色相偏差影响不大，成本优势就能用足。
第二，熔指必须和模具匹配。ABS副牌的熔指波动比正牌大，同一家厂不同批次的熔指可能差2-3个点。选之前先确认自己模具的流道和浇注口适不适应，别拿高熔指料去打需要韧性的件。
第三，要看包装与批次。原厂原包的副牌，包装上仍带原厂标识；拆开过的散包料，批次来源说不清，风险就上去了。
第四，先试料再批量。拿副牌料之前，一定要先要小样试机，确认熔指、冲击、色相三项关键指标在自己产品的接受范围内，再谈批量价格。
科隆仓库现货｜国产ABS先测后签
科隆在宁波仓库常备国产ABS副牌现货，主推品牌覆盖吉林石化、大庆石化、天津渤化三家国内头部企业。主要牌号涵盖通用注塑级与耐热级多个常用型号，包装分大包装与小包装两种。
仓库现货通常在5000吨左右：小包副牌备货800-1000吨，箱装副牌备货300-500吨，大包料/吨包料备货3500-3900吨。
供应保障走先测后签：每批副牌料进厂先做熔指、冲击、色相三项快测，指标确认后再签合同放行；批次留样可追溯，检测单随货走，来料验收有据可查。
选型口诀与案例
国产ABS副牌怎么选？记住四句话：先定用途再选厂，熔指匹配是关键，小样试机再放量，原厂原包不贪散。
中山一家做小家电外壳的注塑厂，此前一直用某进口正牌ABS，每吨成本居高不下。今年改用科隆供的吉林石化ABS副牌通用级，先拿两吨小样试机，熔指和冲击指标都在产品接受范围内，批量切料后外壳合格率稳定在97%以上，每吨原料成本降了近两千元。厂长说：不是国产副牌不行，是之前没找对渠道。
Here's a set of numbers: By 2025, China's total ABS production capacity will exceed 6 million tons, with domestic materials accounting for over 60%. But if you look around the market, you'll notice a very fragmented phenomenon—genuine ABS prices are inverted and profits are as thin as paper, recycled ABS are everywhere with uneven quality, and the actual sub-brand materials released by the original factory have become the "those who know" the injection molding plant owners.
Here's the question: Which domestic ABS sub-brand can compete? Today, let's thoroughly explain the sub-brand secrets of Jilin Petrochemical, Daqing Petrochemical, and Tianjin Bohua, the three leading domestic ABS manufacturers. What is
ABS? At a certain stage in the domestic landscape
ABS is acrylonitrile–butadiene–styrene three-way copolymer, each responsible for one thing: acrylonitrile handles chemistry and heat resistance, butadiene handles impact toughness, and styrene handles surface gloss and processing fluidity. Because these three can be adjusted, ABS can be used from home appliance shells to car interiors, from toys to luggage boxes, with extremely wide applications.
After nearly ten years of expansion, domestic ABS production capacity has shifted from "completely dependent on imports" to "mainly domestic with imports supplemented." By capacity range, the leading domestic tier includes PetroChina (Jilin Petrochemical, Daqing Petrochemical), Sinopec, Tianjin Bohua, as well as Taiwanese and foreign factories in China. Taiwanese Chimei, Ningbo Taiwan Chemical, and foreign LG Chem have considerable factory capacities in China, but based on the "domestic = Chinese mainland local enterprise" perspective, this article focuses on Jilin Petrochemical, Daqing Petrochemical, and Tianjin Bohua.
Where do domestic ABS sub-brands come from ?
First, clarify the concept: ABS sub-brands are the parts of the same polymerization device and grade system, where some indicators slightly deviate from the genuine standard during factory inspection. They are not recycled materials, not recycled materials, and certainly not sprue material re-pelletized—the molecular chain structure is exactly the same as the genuine brand, and the base material is original factory particles.
The main sources of sub-brands are four types: starting and shutting down of the plant, transition materials during grade switching, batches with melting fingers or hues slightly exceeding standards due to process fluctuations, and auxiliary line tail materials. For ABS, common sub-brand differences are concentrated in melting index fluctuations, slightly lower impact strength, yellowish or deeper hue, and slightly higher ash content in some batches.
Here is a boundary table you must remember: genuine brands meet all indicators, have stable batches, and are certified as high requirements; Sub-brands have slight deviations in individual indicators but same base material, suitable for internal parts, color-matched parts, and general structural parts; Reprocessed material is processed scrap material and then pelletized, having already undergone one a heat cycle; Recycled material is recycled plastic and pelletized, with large performance fluctuations. Using the secondary brand as recycled material wastes raw materials; Buying recycled material as a secondary brand is irresponsible to the product.
Jilin Petrochemical: The long-standing foundation of PetroChina ABS, with the most complete grade system
Jilin Petrochemical is affiliated with PetroChina and is a long-established main producer in the domestic ABS industry. The synthetic resin plant has long been regarded by the industry as the core base for PetroChina's ABS. Its ABS product line covers general-purpose grade, sheet grade, flame-retardant grade, heat-resistant grade, and other directions, making its grade system relatively comprehensive among domestic materials.
In terms of representative grades, Jilin Petrochemical ABS mainly focuses on general injection molding grades, balancing modified substrates and home appliance shell needs. Its sub-brand materials are characterized by relatively controllable melting index fluctuations and occasional color deviations, but a stable balance of substrate toughness and rigidity. For injection molding factories producing ordinary home appliance interiors, small appliance shells, toys, and luggage accessories, Jilin Petrochemical's ABS sub-brand is a "sufficient and stable" choice.
Applicable scenarios: home appliance inner shells, small appliance shells, toys, daily necessities, and modified base material blending.
Daqing Petrochemical: The other pole of PetroChina's ABS, with a reputation for heat resistance grade
Daqing Petrochemical is also part of PetroChina. After recent capacity expansion and upgrades, its ABS units rank among the top domestic ABS brands. There is an industry saying: Daqing Petrochemical's heat-resistant ABS has a certain market share in small appliances requiring short-term heat resistance, such as rice cookers and rice cooker inner pots. In terms of
representative grades, Daqing Petrochemical's ABS covers both general-purpose and heat-resistant grades, with some grades having stable customers in the high-temperature appliance sector. The characteristics of its sub-brand materials are: the heat-resistant sub-grade still has a solid foundation in short-term heat resistance, suitable for products with heat resistance requirements but not certified parts; the general-grade sub-brand is suitable for internal structural parts with lower appearance requirements.
Applicable scenarios: rice cooker/microwave oven peripheral parts, air conditioner internal parts, fan blades, general structural parts.
Tianjin Bohua (Dagu Chemical): Another Pole of Northern ABS
Tianjin Bohua's Dagu Chemical is an important ABS resin manufacturer in northern China, with hundreds of thousands of tons of ABS production units. The "Red Three Crystals" trademark is well-known in northern markets. Its product line covers ABS, styrene, and AS resin, with relatively complete equipment support.
Representative Grade: Dagu Chemical ABS mainly uses general injection molding grade, balancing sheet and extrusion grade requirements. The characteristics of its sub-brand material are: general-grade sub-brand has good processing fluidity, suitable for thin-walled products and multi-cavity molds; Hue deviation is the most common point of difference among sub-brands, making it more suitable for dark-colored products or color parts.
Applicable scenarios: TV housings, monitor frames, toys, daily-use plastic products, color-matched parts.
How to choose domestic ABS secondary brands without pitfalls
First, first decide the intended use, then select the grade. When making light-colored appearance parts, don't use sub-brands with color deviation; For dark-colored parts or internal structural parts, hue deviation doesn't have much impact, so the cost advantage can be fully utilized.
Second, the melt index must match the mold. The melt index of ABS secondary brands fluctuates more than the genuine brand; melt fingers from different batches from the same factory may differ by 2-3 points. Before choosing, first confirm whether the flow channel and pouring port of your mold are suitable. Don't use high-melt finger material to make parts that require toughness.
Third, check the packaging and batch. For sub-brands with original original packaging, the packaging still bears the original factory mark; For unopened bulk packages, the origin of the batch is unclear, which increases the risk.
Fourth, test the material before batching. Before getting sub-brand materials, you must first test the machine with small samples, confirming that the melting index, impact, and hue are within the acceptable range of your product, then negotiate batch prices.
Cologne Warehouse Stock | Domestic ABS Test Before Signing
Cologne maintains domestic ABS sub-brand stock at the Ningbo warehouse, with main brands covering three leading domestic companies: Jilin Petrochemical, Daqing Petrochemical, and Tianjin Bohua. Main grades cover common models of general injection molding grade and heat-resistant grade, with packaging divided into large and small packaging.
warehouse stock is usually around 5,000 tons: small sub-brand stock is 800-1,000 tons, sub-brand containerized stock is 300-500 tons, and large package/ton packaging stock is 3,500-3,900 tons.
Supply guarantee: test first, then sign: each batch of sub-brand material first undergoes quick testing of melt index, impact, and hue; only after indicators are confirmed are contracts signed and released; Batch samples are traceable, inspection orders are sent with the goods, and incoming material acceptance is evidence-based.
Selection tips and case studies
How to choose domestic ABS secondary brands? Remember these four points: first determine the purpose, then choose the factory. Melt finger matching is key, small samples are tested before scaling up, and the original factory does not scatter the original packaging.
Zhongshan is an injection molding factory that makes small appliance casings. Previously, it used a certain imported genuine ABS with high cost per ton. This year, they switched to Jilin Petrochemical ABS sub-brand general-grade supplied by Kelon, first testing with two tons of small samples. The melt index and impact indicators were within product acceptable ranges, and after batch cutting, the shell pass rate remained stable above 97%, reducing raw material costs by nearly 2,000 yuan per ton. The factory director said: It's not that domestic sub-brands are bad, it's that they didn't find the right channel before
