先抛一组数字：国内真正做溶液聚合丁苯橡胶（SSBR）的本土产能满打满算三十多万吨，独山子一家就占了十六万吨；而市场上挂着"SSBR副牌"在卖的货，能凑出这个数的两倍还多。差额从哪来？有人拿乳聚丁苯（ESBR）改一改当SSBR卖，有人把不同门尼的批次混着装。轮胎厂一上车，磨耗指数和滚阻就露馅。SSBR这东西，副牌不是不能用，是门尼和配方不对路，一车胎面胶就报废。
今天就把中石油独山子石化、中石化高桥石化、中石化燕山石化这三家国内SSBR头部企业的副牌门道，一次讲透。
SSBR是什么？国内产能都在谁手里
SSBR是溶液聚合丁苯橡胶，和常见的乳聚丁苯（ESBR）工艺路线不同。溶液聚合让苯乙烯和丁二烯的结合更均匀，乙烯基含量可控，做出来的胎面胶抓地、耐磨、滚动阻力三项平衡得更好，是绿色轮胎和高性能轮胎的主力胶种。它八成以上用在轮胎胎面，剩下在透明鞋底、塑料改性增韧上。
国内大陆SSBR产能集中在两家央企体系。中石油独山子石化是绝对主力，溶聚丁苯总产能做到十六万吨每年，还自主攻克了双端官能化SSBR，是国产高性能胎面胶的顶梁柱；中石化体系里，高桥石化约六点七万吨每年，是中石化SSBR的主要基地，燕山石化约三万吨每年，是国内较早的SSBR装置之一。需要说明，茂名石化、齐鲁石化这些名字更响的厂做的是乳聚丁苯（ESBR），不是本文说的SSBR，别买混了。台橡宁波、镇江奇美属于台资，辽宁北方戴纳索是外资合资，都不算国内大陆头部。
SSBR副牌：门尼粘度和充油量是两道坎
SSBR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SSBR上，副牌最常见的差异点集中在四项：门尼粘度波动、苯乙烯与丁二烯比例小幅偏移、充油量偏差、色相深浅不一。
为什么这几项关键？轮胎厂配方是按门尼粘度卡着调的，门尼差五个单位，混炼吃料速度和硫化曲线就变了；充油量直接影响硬度和滚阻，充多了胎面发软、磨耗快；苯乙烯含量高了胶变硬、抓地掉一截。这些指标偏差一点，胎面性能就不是一个档次。
和回料的区别要说清楚：SSBR回料是废旧轮胎、鞋底破碎再生，分子链已经断过一次，性能波动极大；SSBR副牌是原厂原生胶块，只是个别指标小幅偏离。做高性能胎面，用副牌是"门尼能不能对上配方"的问题，用回料是"能不能过主机厂认证"的问题。
中石油独山子石化：国产SSBR的产量担当
独山子石化是国内SSBR产能最大的企业，溶聚丁苯总产能十六万吨每年，下游客户覆盖多家头部轮胎厂。它在二〇二一年靠自主技术建成六万吨生产线，二〇二三年又投产二点五万吨官能化SSBR间歇线，双端官能化产品在国内属于从零到一的突破。代表牌号上，独山子有轮胎用高性能系列、高端透明鞋底料系列等。
独山子副牌料的特点是：央企批次管理规范，门尼粘度批次间波动相对小；官能化和普通牌号都有，胎面配方厂选择面宽；缺点是新疆基地到华东华南运距长，交货周期和运费要提前算。
适用场景：高性能轮胎胎面、绿色轮胎、透明鞋底、橡胶增韧改性。
中石化高桥石化：华东SSBR主力基地
高桥石化是中石化体系内SSBR的主要生产基地，产能约六点七万吨每年，地处上海，靠近长三角轮胎和鞋底产业带。它在绿色轮胎胎面胶方向有较长积累，产品供国内主流轮胎厂。
高桥副牌料的特点是：区位优势明显，华东客户提货距离近、响应快；中石化牌号体系成熟，胎面级产品口碑稳定；副牌批次以门尼和色相小幅偏离为主，适合对成本敏感、配方容忍度高的胎面和鞋底制品。
适用场景：乘用车胎面胶、卡车胎面、鞋底料、橡胶制品。
中石化燕山石化：国内SSBR老牌装置
燕山石化是国内较早布局SSBR的企业之一，产能约三万吨每年，地处北京，技术积累深厚。它的SSBR牌号在行业里历史久，是很多老牌轮胎厂配方里的常客。
燕山副牌料的特点是：技术底蕴厚，牌号切换和工艺波动料的指标边界清晰；产能规模相对小，适合中小批量、配方成熟的轮胎和制品厂；华北及周边客户采购便利。
适用场景：轮胎胎面、工业橡胶制品、鞋底、塑料增韧。
SSBR副牌避坑指南
第一，先分清SSBR和ESBR。乳聚丁苯（ESBR）便宜，但工艺路线和性能完全不同，别拿ESBR当SSBR上车，磨耗和滚阻过不了。
第二，门尼粘度必须对上配方。轮胎厂换副牌前先做小试，确认门尼在配方窗口内，别拿高门尼副牌硬掺。
第三，充油量和苯乙烯含量要问清楚。这两项直接决定硬度和抓地，不问清楚就上车，批次间硬度漂移会被投诉。
第四，主机厂认证胎面别用副牌。配套车厂原配胎的胎面胶有认证要求，必须用正牌，副牌只用于替换胎、售后胎和非认证制品。

选型口诀与案例
国产SSBR副牌怎么选？记住四句话：先分SSBR和ESBR，门尼对得上配方，充油量问清楚，认证胎面不碰副牌。
衢州一家做售后替换胎的轮胎厂，原来一直用进口SSBR正牌做胎面，每吨胶料成本偏高。今年改用科隆供的高桥石化SSBR副牌胎面级，先拉一车小样做配方试验，门尼粘度和充油量都落在原配方窗口里，批量上车后磨耗和滚阻检测稳定，成品胎通过省内检测线抽检，每吨胶料成本降了两千一百元。厂长说：做替换胎不做原配认证，门尼够、指标稳，为什么要花进口正牌的钱？
Here's a set of numbers: The domestic production capacity for solution-based polymerized styrene-butadiene rubber (SSBR) in China is over 300,000 tons at best, with Dushanzi alone accounting for 160,000 tons; And the goods sold under the "SSBR sub-brand" can more than double that amount. Where does the difference come from? Some people convert emulsion polystyrene-butadiene (ESBR) and sell it as SSBR, while others mix different Mooney batches. As soon as tire factories get on the cars, their wear index and rolling resistance are exposed. SSBR isn't that the sub-brand can't be used; it's just that the Mooney formula is off, and the tread rubber is scrapped by a whole truck.
Today, let's thoroughly explain the secrets of the sub-brands of PetroChina Dushanzi Petrochemical, Sinopec Gaoqiao Petrochemical, and Sinopec Yanshan Petrochemical . What is
SSBR? Who owns domestic production capacity
SSBR is solution-based polymerized styrene-butadiene rubber, which differs from the common emulsion polystyrene-butadiene (ESBR) process route. Solution polymerization allows the bonding of styrene and butadiene to be more uniform, the vinyl content is controllable, and the resulting tread rubber balances grip, wear resistance, and rolling resistance, making it the main rubber for green and high-performance tires. Over 80% of it is used in tire tread, with the rest on transparent soles and plastic modification and toughening.
Mainland China's SSBR production capacity is concentrated in two central enterprise systems. PetroChina Dushanzi Petrochemical is the absolute main player, with a total annual capacity of 160,000 tons of poly-butadiene-butadiene and has independently conquered dual-end functional SSBR, making it the backbone of high-performance tread rubber in China; Within the Sinopec system, Gaoqiao Petrochemical is about 67,000 tons per year, making it the main base for Sinopec's SSBR, and Yanshan Petrochemical is about 30,000 tons per year, making it one of the earliest SSBR units in China. It should be noted that more well-known plants like Maoming Petrochemical and Qilu Petrochemical produce emulsion polybutadiene-butadiene (ESBR), not the SSBR mentioned here, so don't mix them up. Taixiang Ningbo and Zhenjiang Chimei are Taiwan-funded, while Liaoning Beifang Dyneso is a foreign joint venture, neither is considered a leading domestic mainland company.
SSBR sub-brand: Mooney viscosity and fuel filling amount are two
SSBR key thresholds. These are sub-brands, and the inspection indicators within the same factory grade system show slight deviations. For SSBR, the most common differences for sub-brands are concentrated in four items: Mooney viscosity fluctuation, slight deviation in the styrene-to-butadiene ratio, fuel fill deviation, and varying hue depth.
Why are these key factors? The tire factory formula is adjusted according to Mooney viscosity. If Mooney differs by five units, the mixing feed rate and vulcanization curve will change; The amount of fuel directly affects hardness and rolling resistance; if filled too much, the tread becomes soft and wears faster; If the styrene content is high, the rubber hardens and grip drops significantly. If these indicators deviate even slightly, the tread performance is on a completely different level. The difference between
and recycled material needs to be clarified: SSBR recycled material is recycled from crushed waste tires and soles, with molecular chains broken once, causing significant performance fluctuations; SSBR secondary brand is original factory rubber blocks, with only slight deviations in some indicators. For high-performance tread, using secondary brands is a matter of "whether the Mooney can match the formula," while using recycled material is a matter of "whether it can pass OEM certification."
PetroChina Dushanzi Petrochemical: The main producer of domestic SSBR production
Dushanzi Petrochemical is the largest domestic SSBR production capacity, with a total annual capacity of 160,000 tons of polybutadiene-butadiene and downstream customers covering several leading tire factories. In 2021, it built a 60,000-ton production line using independent technology, and in 2023, it launched a 25,000-ton functional SSBR intermittent line. Its dual-end functional products represent a breakthrough from zero to one domestically. In terms of representative grades, Dushanzi offers high-performance tire series and high-end transparent sole material series. The characteristics of
Dushanzi's sub-brand materials are: standardized batch management by central enterprises, with relatively small fluctuations in Mooney viscosity between batches; Both functional and standard grades are available, with a wide range of tread formula options; The downside is that the Xinjiang base has long transportation distances from East and South China, so delivery cycles and freight costs must be calculated in advance.
Applicable scenarios: high-performance tire tread, green tires, transparent soles, rubber toughening modification.
Sinopec Gaoqiao Petrochemical: Main base for East China SSBR
Gaoqiao Petrochemical is the main SSBR production base within Sinopec's system, with an annual capacity of about 67,000 tons, located in Shanghai, close to the Yangtze River Delta tire and sole industry belt. It has a long accumulation in green tire tread rubber, supplying mainstream domestic tire manufacturers. The characteristics of
Gaoqiao sub-brand material are: obvious location advantage, close delivery distance and quick response to East China customers; Sinopec's mature grade system, stable reputation for tread-grade products; Sub-brand batches mainly feature slight deviations in Mooney and hue, suitable for tread and sole products sensitive to cost sensitivity and high formulation tolerance.
Applicable scenarios: passenger car tread rubber, truck tread material, shoe sole material, rubber products.
Sinopec Yanshan Petrochemical: Established domestic SSBR unit
Yanshan Petrochemical is one of the earliest domestic companies to deploy SSBR, with an annual capacity of about 30,000 tons. Located in Beijing, it has deep technical expertise. Its SSBR grade has a long history in the industry and is a regular ingredient in many established tire manufacturers' formulas. The characteristics of
Yanshan sub-brand material are: deep technical foundation, clear indicator boundaries for grade switching and process fluctuation; relatively small production capacity, suitable for small to medium-batch tire and product factories with mature formulas; convenient procurement for customers in North China and surrounding areas.
Applicable scenarios: tire tread, industrial rubber products, shoe soles, plastic toughening.
SSBR secondary brand pitfall guide
First, distinguish between SSBR and ESBR. Milk polystyrene-butadiene (ESBR) is cheap, but the manufacturing route and performance are completely different. Don't use ESBR as SSBR for SSBR, as it won't withstand wear and rolling resistance.
Second, Mooney viscosity must match the formula. Before replacing the secondary brand, tire manufacturers should conduct a small test to confirm Mooney is within the formula window; do not forcibly blend with the high-grade Mooney secondary brand.
Third, ask clearly about the fuel filling amount and styrene content. These two factors directly determine hardness and grip. If you get in without clarifying, you may be complained about if hardness drift occurs between batches.
Fourth, OEM tread certification should not use secondary brands. The tread rubber used by the original tire supplier has certification requirements and must be genuine; secondary brands are only used for replacement tires, aftermarket tires, and uncertified products.
Cologne warehouse stock | Complete range of domestic SSBR grades
Cologne maintains domestic SSBR secondary brand stock at the Ningbo warehouse, with main brands covering three leading domestic companies: PetroChina Dushanzi Petrochemical, Sinopec Gaoqiao Petrochemical, and Sinopec Yanshan Petrochemical. Main grades cover common tread and outsole models, with packaging in large and small packages, mixed according to customer formula requirements.
Warehouse stock is usually around 5,000 tons: small parcel sub-brand stock is 800-1,000 tons, boxed sub-brand stock is 300-500 tons, and large bulk materials per ton are 3,500-3,900 tons.
Supply assurance follows a first-test-then-sign approach: each batch of SSBR sub-brand material is first sampled for three key indicators—Mooney viscosity, fuel filling, and styrene content—and only after passing the tests is contract signed; Batch samples are traceable, and before tire factories change materials, Cologne can provide small samples for formulation validation.
Selection Mnemonics and Case Studies
How to choose domestic SSBR sub-brands? Remember these four points: first separate SSBR and ESBR, make sure the formula matches the Manney grade, ask clearly about the fuel filling, and certify the tread doesn't touch the secondary brand.
Quzhou, a tire factory that does aftermarket replacement tires used to use genuine imported SSBR for the tread, which was relatively high per ton of rubber cost. This year, they switched to using Takahashi Petrochemical's SSBR secondary tread grade supplied by Cologne. They first took a truckload of samples for formula testing. The Mannier viscosity and fuel fill were both within the original formula window, and after batch installation, wear and rolling resistance tests were stable. The finished tires passed provincial inspection lines and were sampled, reducing the cost of compound compound by 2,100 yuan per ton. The factory director said: Replacing tires without original certification means Manney is sufficient and the indicators are stable. Why spend money on imported genuine tires?
