一说尼龙，大家想到的都是石油基的PA6、PA66。但有一种尼龙，原料来自蓖麻油，是中国人自己发明的，生物基、可再生、耐低温、耐腐蚀——这就是PA1010。很多工程师觉得这种"小众尼龙"国产料不靠谱，但你可能不知道，国内专门做蓖麻油基PA1010的企业已经做了很多年。
PA1010是什么 国产生物基尼龙
PA1010（聚癸二酰癸二胺）由癸二酸和癸二胺聚合而成，两种单体都来自蓖麻油。它是中国在上世纪60年代自主开发的尼龙品种，也是全球极少数由中国率先工业化的尼龙材料。PA1010的特点是密度低、吸水率低、尺寸稳定性好、耐低温冲击、耐油耐化学腐蚀，大量用于医疗器械、精密机械部件、电线电缆、体育器材等领域。
国内PA1010生产企业主要集中在山东地区。山东祥龙新材料股份有限公司是PA1010生物基尼龙的源头聚合企业，100%生物基原料来自蓖麻油，产品对标进口材料，应用于医疗挤出和改性工程塑料行业。此外，山东东辰瑞森作为长碳链尼龙专业企业，其产品线也涵盖PA1010。金发科技旗下的Orinko Advanced Plastics也有PA1010树脂产品。
外资方面，PA1010作为中国特色尼龙品种，海外生产商较少，主要是中国企业主导。这一点和PA6、PA66完全不同——PA1010是真正的"中国原创"尼龙。
PA1010副牌 生物基尼龙的副牌怎么看
PA1010副牌是原厂聚合生产线上粘度或含水率小幅偏离标准的原生树脂。PA1010的核心指标是相对粘度和熔点——粘度决定分子量和力学性能，熔点影响加工温度窗口。副牌PA1010通常粘度偏差0.05以内，或者熔点略偏。
副牌来源仍是四大类：开停车头尾料、牌号切换过渡料、聚合工艺波动导致粘度小幅偏离的批次、副线尾料。祥龙新材料作为专注PA1010的聚合企业，其副牌主要来源于工艺波动和牌号切换批次。
和回料的区别：PA1010回料经过再次挤出后，生物基链段可能发生降解，力学性能下降。副牌PA1010是原厂原生聚合粒子，分子结构完整。特别是医疗级应用，必须用正牌或原厂副牌，回料绝对不能用——生物相容性和杂质含量没有保障。
山东祥龙新材料 蓖麻油基PA1010源头厂
山东祥龙新材料股份有限公司位于山东，是专注生物基尼龙PA1010的源头聚合工厂。公司产品100%生物基，原料来自蓖麻油，对标进口材料，主要应用于医疗挤出、改性工程塑料等行业，安全环保，可食品级接触。祥龙新材料在盖德化工网等平台长期供货PA1010树脂，牌号覆盖通用级和挤出级。
祥龙PA1010的核心竞争力在于专注——不像东辰瑞森做全系列长碳链尼龙，祥龙集中精力做PA1010这一个品种，工艺控制精细度高。作为蓖麻油基PA1010的专业生产企业，祥龙在原料端和蓖麻油加工企业有长期合作，癸二酸和癸二胺的供应链稳定。
副牌方面，祥龙PA1010副牌以小包装为主，主要来源于聚合工艺波动导致粘度小幅偏离的批次。对于做一般工业配件、线缆护套、体育器材等对医疗级纯度要求不高的制品，祥龙副牌PA1010性价比突出。第二梯队方面，山东东辰瑞森和金发科技（Orinko）也有PA1010产品线，可作为备选货源。
PA1010副牌进厂 粘度含水率双测
第一，测相对粘度。PA1010副牌的核心指标是相对粘度。粘度低了分子量小，制品强度不够。进货前要求供应商提供同批次粘度数据，到货后用乌氏粘度计复测。医疗级应用按正牌标准验收。
第二，控制含水率。PA1010虽然吸湿性比PA66低，但挤出前仍需干燥。副牌PA1010如果含水率偏高，挤出时会出现银纹和气泡。建议干燥温度80℃左右，干燥时间6小时以上。
第三，按应用分级。医疗挤出、食品接触级用正牌稳妥；一般工业配件、线缆护套可以用副牌。不要在医疗级产品上用副牌——生物相容性和杂质含量没有第三方认证，出了问题说不清。

When it comes to nylon, everyone thinks of petroleum-based PA6 and PA66. But there is one type of nylon whose raw material comes from castor oil, invented by the Chinese themselves, bio-based, renewable, resistant to low temperatures, and corrosion—this is PA1010. Many engineers think this "niche nylon" domestic material is unreliable, but you might not know that domestic companies specializing in castor oil-based PA1010 have been doing this for many years. What is
PA1010? Domestically produced nylon
PA1010 (polysacyldecadiamide) is made by polymerizing sebanedioic acid and decylenediamine, both monomers from castor oil. It is a nylon variety independently developed by China in the 1960s and is one of the very few nylon materials industrialized by China worldwide. PA1010 is characterized by low density, low water absorption, good dimensional stability, resistance to low-temperature impact, oil and chemical corrosion, and is widely used in medical devices, precision machinery components, wires and cables, sports equipment, and other fields.
Domestic PA1010 manufacturers are mainly concentrated in Shandong. Shandong Xianglong New Materials Co., Ltd. is the original polymerization enterprise for PA1010 bio-based nylon, with 100% bio-based raw materials sourced from castor oil. The products are aligned with imported materials and used in the medical extrusion and modified engineering plastics industry. Additionally, Shandong Dongchen Ruisen, as a specialized company in long-carbon chain nylon, also has a product line covering PA1010. Orinko Advanced Plastics, a subsidiary of Kingfa Technology, also has PA1010 resin products.
In terms of foreign investment, PA1010, as a type of nylon with Chinese characteristics, has few overseas producers and is mainly dominated by Chinese companies. This is completely different from PA6 and PA66—PA1010 is truly a "Chinese original" nylon.
PA1010 Sub-brand: How to view the sub-brand of bio-based nylon
PA1010 Sub-brand is the original resin on the polymerization production line with slightly deviated viscosity or moisture content from the standard. The core indicators of PA1010 are relative viscosity and melting point—viscosity determines molecular weight and mechanical properties, while melting point affects the processing temperature window. Sub-brand PA1010 usually has a viscosity deviation within 0.05, or the melting point is slightly off.
The secondary brand still comes from four main categories: start-stop and tail materials, grade switching transition materials, batches with slight viscosity deviations caused by polymerization process fluctuations, and auxiliary line tailings. As a polymerization company specializing in PA1010, Xianglong New Materials' sub-brand mainly comes from process fluctuations and batch changes in grades. Difference between
and recycled material: After re-extrusion of PA1010 backfill, bio-based chain segments may degrade, resulting in reduced mechanical properties. Sub-brand PA1010 is original original polymerized particles with intact molecular structure. Especially for medical-grade applications, genuine or original sub-brand products must be used; recycled materials must not be used—biocompatibility and impurity content are not guaranteed.
Shandong Xianglong New Materials Castor Oil-Based PA1010 Source Factory
Shandong Xianglong New Materials Co., Ltd. is located in Shandong and specializes in the source polymerization factory for bio-based nylon PA1010. The company's products are 100% bio-based, with raw materials sourced from castor oil, benchmarked against imported materials, mainly used in medical extrusion and modified engineering plastics, safe and environmentally friendly, and food-grade accessible. Xianglong New Materials has long supplied PA1010 resin on platforms such as Gaide Chemical Network, with grades covering both general-purpose and extrusion grades.
Xianglong PA1010's core competitiveness lies in focus—unlike Dongchen Ruisen, which focuses on the full range of long-carbon chain nylon, Xianglong focuses on PA1010 alone, with highly precise process control. As a professional manufacturer of castor oil-based PA1010, Xianglong has long-term cooperation with castor oil processing companies on the raw material side, ensuring stable supply chains for sabic acid and decylenediamine. For
secondary brands, Xianglong PA1010 secondary brands mainly come in small packages, mainly from batches where polymerization process fluctuations cause slight viscosity deviations. For general industrial accessories, cable sheaths, sports equipment, and other products that do not require high medical-grade purity, Xianglong secondary PA1010 stands out for its cost-effectiveness. In the second tier, Shandong Dongchen Ruisen and Kingfa Technology (Orinko) also have PA1010 product lines and can be considered alternative sources.
PA1010 secondary brands enter factories: Viscosity and moisture content double tests
First, measuring relative viscosity. The core indicator of PA1010 secondary brands is relative viscosity. Low viscosity means smaller molecular weight and insufficient product strength. Before purchase, suppliers are required to provide viscosity data for the same batch, and after arrival, re-measure with a Uhlmann viscometer. Medical-grade applications are accepted according to genuine brand standards.
Second, control moisture content. Although PA1010 has lower moisture absorption than PA66, it still needs to be dried before extrusion. If the secondary brand PA1010 has a high moisture content, silver marks and bubbles will appear during extrusion. It is recommended to dry at around 80°C and dry for more than 6 hours.
Third, classification by application. Medical extrusion and food contact grade should be safe to use genuine brands; General industrial accessories and cable sheaths can use secondary brands. Do not use secondary brands on medical-grade products—if there is no third-party certification for biocompatibility and impurity content, problems can be hard to explain.
