塑料圈有个鄙视链：做透明GPPS的看不起做HIPS的，做HIPS的看不起做回料的，做回料的看不起拿HIPS当ABS卖的。但你真要做家电外壳、冰箱内胆、打印机外壳，绕不开HIPS——它比GPPS韧，比ABS便宜，中间档的活儿正好是它的地盘。
问题是：国产HIPS副牌，怎么选才不踩坑？中石化、中石油、星辉环材这三家，谁的料更靠得住？
HIPS是什么？和ABS、GPPS什么关系
HIPS是高抗冲聚苯乙烯，在GPPS基体里引入了丁二烯橡胶粒子，牺牲一部分透明性，换来冲击韧性。HIPS不透明，但刚性和韧性平衡得好，加工流动性佳，价格比ABS低一档，因此在家电外壳、冰箱内胆、办公用品外壳、玩具、包装材料领域用量极大。
和ABS的区别：ABS含丙烯腈，耐化学和耐热更好；HIPS不含丙烯腈，价格更低、韧性够用。很多家电外壳原来用ABS的，现在改用HIPS降本，前提是产品对耐化学和耐热要求不极端。
国内HIPS产能同样集中在中石化和中石油两大体系。中石化旗下扬子石化、齐鲁石化等装置产能较大；中石油旗下大庆石化、吉林石化在东北区域有稳定供应。星辉环材（汕头）作为民营PS专业厂，HIPS年产能与GPPS合计35万吨，是华南地区PS龙头。
HIPS副牌：韧性和光泽是两个命门
HIPS副牌，是原厂同一牌号体系里检验指标小幅偏离的批次。落到HIPS上，副牌最常见的差异点集中在三项：冲击强度略低、表面光泽偏差、熔指波动。
为什么这三项关键？HIPS的核心卖点就是"韧且亮"。冲击强度差了，外壳一摔就裂；表面光泽差了，家电外壳看着发乌、不够亮；熔指波动大，大件制品充模不稳定。
和回料的区别再说一遍：HIPS回料是制品外壳破碎再造粒，冲击强度已经衰减很多，表面光泽也没了；HIPS副牌是原厂原生粒子，只是个别指标小幅偏离。做冰箱内胆，用副牌是"光泽够不够"的问题，用回料是"敢不敢用"的问题。
中石化：扬子石化为核心，家电外壳有口碑
中石化旗下HIPS产能以扬子石化为核心，配套齐鲁石化等装置。依托中石化炼化一体化优势，中石化HIPS在家电外壳、包装材料领域有大量稳定客户，中高端牌号（高光泽、阻燃、耐热改性系列）供应能力较强。

HIPS副牌避坑指南
第一，家电外观件别拿光泽偏差的副牌。做电视机外壳、显示器边框，表面光泽是硬指标，副牌光泽差了客户一眼就看出来。
第二，受力件别拿冲击强度偏低的副牌。HIPS副牌冲击强度比正牌低一截，受力外壳、承重件不要用。
第三，阻燃件必须要认证。HIPS阻燃副牌的阻燃等级可能小幅偏离，有阻燃认证要求的产品（如电器外壳）必须用正牌，别拿副牌赌。
第四，就近采购。华南客户优先考虑星辉环材，华东客户优先考虑中石化系，东北客户优先考虑中石油系——HIPS单价不高，运费占比不小。

选型口诀与案例
国产HIPS副牌怎么选？记住四句话：外观件看光泽，受力件看冲击，阻燃件别用副牌，就近采购降成本。
苏州一家做打印机外壳的注塑厂，此前一直用某进口HIPS正牌，每吨成本偏高。今年改用科隆供的中石化HIPS副牌高光泽级，先拿两吨小样试机，表面光泽和冲击强度都在产品接受范围内，批量切料后外壳客户验收通过，每吨原料成本降了近一千八百元。厂长说：打印机外壳不是认证件，副牌光泽够用，为什么要花正牌的钱？
There is a hierarchy of disdain in the plastic industry: those who produce transparent GPPS look down on those who make HIPS, those who make HIPS look down on those who use recycled material, and those who use recycled material look down on those who sell HIPS as ABS. But if you really want to make household appliance shells, refrigerator linings, or printer housings, you can't avoid HIPS — it's tougher than GPPS, cheaper than ABS, and perfectly suited for mid-range applications.
The question is: For domestic HIPS secondary brands, how do you choose without falling into pitfalls? Among Sinopec, PetroChina, and Xinghui Environmental Materials, whose material is more reliable?
What is HIPS? What is its relationship with ABS and GPPS?
HIPS is high-impact polystyrene, in which butadiene rubber particles are introduced into the GPPS matrix, sacrificing some transparency in exchange for impact toughness. HIPS is opaque, but it has a good balance of rigidity and toughness, excellent processing flow, and a price slightly lower than ABS. Therefore, it is widely used in the fields of household appliance housings, refrigerator liners, office supply casings, toys, and packaging materials.
Difference from ABS: ABS contains acrylonitrile, which provides better chemical resistance and heat resistance; HIPS does not contain acrylonitrile, is cheaper, and has sufficient toughness. Many appliance casings originally used ABS, but now switch to HIPS to reduce costs, provided the product does not have extreme requirements for chemical resistance and heat resistance.
Domestic HIPS production capacity is also concentrated in the two major systems of Sinopec and PetroChina. Sinopec's subsidiaries, such as Yangzi Petrochemical and Qilu Petrochemical, have relatively large production capacities; PetroChina's subsidiaries, such as Daqing Petrochemical and Jilin Petrochemical, provide stable supply in the Northeast region. Xinghui Huancai (Shantou), as a private PS specialized manufacturer, has an annual HIPS production capacity of 350,000 tons combined with GPPS, making it the leading PS producer in South China.
HIPS sub-brand: Toughness and gloss are two crucial points
HIPS secondary grade refers to batches whose test indicators slightly deviate within the same grade system of the original manufacturer. For HIPS, the most common differences in the secondary grade concentrate on three aspects: slightly lower impact strength, surface gloss deviation, and melt index fluctuation.
Why are these three aspects key? The core selling point of HIPS is 'tough and glossy.' If the impact strength is poor, the casing will crack easily when dropped; if the surface gloss is poor, the household appliance casing will look dull and not bright enough; if the melt flow index fluctuates greatly, molding large products will be unstable.
Let me repeat the difference with recycled material: HIPS recycled material is made by crushing the product's outer shell and then re-pelletizing it, so its impact strength has already decreased a lot, and the surface gloss is gone; HIPS secondary grade is the original manufacturer's virgin pellets, with only slight deviations in some indicators. When making refrigerator inner linings, using the secondary grade is a matter of 'is the gloss sufficient,' while using recycled material is a matter of 'do you dare to use it.'
Sinopec: Yangzi Petrochemical as the core, well-known for household appliance casings
Sinopec's HIPS production capacity is centered on Yangzi Petrochemical, supported by units such as Qilu Petrochemical. Relying on Sinopec's refining and chemical integration advantages, Sinopec's HIPS has a large number of stable customers in the fields of household appliance housings and packaging materials, with strong supply capabilities for mid-to-high-end grades (high-gloss, flame-retardant, heat-resistant modified series).
In terms of brand grades, Sinopec HIPS covers multiple directions including high gloss, flame retardant, and heat-resistant grades. The characteristics of its secondary grades are: the secondary high gloss grade still has a base level of surface gloss, suitable for appliance shells that require appearance; the secondary flame retardant grade requires attention as the flame retardant level may slightly deviate, making it unsuitable for certified flame-retardant parts.
Applicable scenarios: TV casings, monitor bezels, printer casings, refrigerator liners, packaging materials.
PetroChina: Daqing Petrochemical as the core, refrigerator liners have tradition
The HIPS production under CNPC is centered on Daqing Petrochemical and Jilin Petrochemical, with stable supply in the Northeast region. Daqing Petrochemical's HIPS has a solid customer base in traditional application areas such as refrigerator liners and large household appliance structural components.
In terms of representative grades, CNPC HIPS mainly focuses on general-purpose and high-impact grades. The characteristics of its secondary grades are: good impact resistance base, suitable for products that require toughness but do not have extreme requirements for gloss; cost advantages are prominent, making them suitable for large-batch, price-sensitive home appliance structural parts.
Applicable scenarios: refrigerator inner liner, washing machine internal parts, air conditioner outer casing, household appliance structural parts, toys.
Starlight Ring Materials: A South China PS specialist, HIPS has strategic products
Xinghui Huancai (Shantou) is a domestic private enterprise specializing in the production of polystyrene, with an annual production capacity of 350,000 tons, operating GPPS and HIPS parallel production lines. Its HIPS products have been designated as key products in the national strategic emerging industries and are widely used in electronics and electrical appliances, toys, daily-use plastics, packaging, building materials, medical devices, and cold chain components.
In terms of brand representation, Xinghui Huancai HIPS covers multiple directions including high-impact and high-gloss types. In recent years, it has continuously developed specialized materials for high-flow, high-gloss HIPS, as well as high-brightness, easy-foaming materials for artistic photo frames. The characteristics of its sub-brand materials are: the product specifications are close to the downstream demand in South China, with mature applications in toys and daily-use products; batch management is standardized, making it suitable for local procurement by injection molding factories in the South China region.
Applicable scenarios: toy shells, electronic and electrical shells, daily plastic products, packaging materials, cold chain components.
HIPS Secondary Brand Pitfall Avoidance Guide
First, don’t use off-brand parts with inconsistent gloss for home appliance exteriors. For TV cases and monitor frames, surface gloss is a strict standard; customers will notice at a glance if the off-brand parts have poor gloss.
Secondly, for load-bearing parts, do not use sub-brands with relatively low impact strength. The impact strength of HIPS sub-brands is lower than that of the main brand, so they should not be used for load-bearing shells or support components.
Third, flame-retardant parts must be certified. The flame-retardant grade of HIPS flame-retardant sub-brands may deviate slightly, so products that require flame-retardant certification (such as appliance housings) must use the genuine brand; do not gamble with sub-brands.
Fourth, source locally. South China customers prioritize Xinghui Environmental Materials, East China customers prioritize Sinopec-affiliated companies, and Northeast customers prioritize PetroChina-affiliated companies—HIPS unit prices are not high, and shipping costs account for a significant portion.
Cologne warehouse spot｜Domestic HIPS large bags and small bags
Cologne keeps a regular stock of domestic HIPS secondary brands in the Ningbo warehouse, mainly promoting brands from the three leading domestic companies: Sinopec, CNPC, and Xinghui Huancai. The main grades cover several commonly used types, including high-gloss, impact-resistant, and general-purpose grades, with packaging available in both large and small sizes.
Warehouse spot goods are usually between 3,000-6,000 tons: small bag secondary brand stock 500-800 tons, boxed secondary brand stock 200-400 tons, large bag material/ton bag material stock 2,500-4,800 tons.
Supply assurance is ensured through direct procurement of original factory packaging: subsidiary brand materials are purchased directly from the original factory channels, with original factory packaging kept intact; each batch comes with original factory test reports, with critical indicators such as impact strength, surface gloss, and melt index accompanying the goods; batch samples are retained for traceability.
Selection Mnemonics and Case Studies
How to choose domestic HIPS secondary brands? Remember four sentences: check the gloss for appearance parts, check the impact resistance for load-bearing parts, don't use secondary brands for flame-retardant parts, and source locally to reduce costs.
An injection molding factory in Suzhou that makes printer casings had been using a certain imported brand-name HIPS, which was quite expensive per ton. This year, they switched to the secondary high-gloss grade HIPS from Sinopec supplied by Kolong. They first tested two tons of small samples on the machines, and the surface gloss and impact strength were both within the acceptable range for the products. After processing in bulk, the casings were approved by the customers, and the cost per ton of raw material dropped by nearly 1,800 yuan. The factory manager said: 'Printer casings are not certified parts, the gloss of the secondary brand is sufficient, so why pay for the brand-name?'
