Global warming and other environmental concerns drive advances in the automotive industry to minimise the environmental impact of today’s cars. Governmental regulations such as Californian Legislation or EURO 4 set restrictive limits for fuel and tailpipe emissions and are tightening towards zero emission levels.

Using renewable source materials and fuel, such as biodiesel and bioethanol significantly reduces greenhouse gas emissions and our edpendence on fossil fuels. Using alternative engine technology, such as hybrid engines, is a further step towards emission- free vehicles.

The use of renewable source fuels such as biodiesel and flexfuel combined with the use of Arkema’s biobased Rilsan PaII can significantly reduce greenhouse gas emissions.

High per formance polyamide

Arkema’s high performance products such as petroleum based Rilsan polyamide 12 and bio – based PAII have been used for over 30 years as a rubber and metal substitute for low-permeation tubing applications in the transportation industry.

Fuel lines and other demanding safety applications have imposed severe requirements on construction materials. These must withstand attack from chemicals, heat or fuel, as well any strong temperature variations for the lifetime of the vehicle. High performance polyamides deliver these critical properties.

End-users benefit from corrosion resistance, easier assembly, and better design possibilities, all at a reduced cost. Rilsan polyamide 11 provides an outstanding level of asfety, durability and versatility for highly demanding applications, and is superior to petroleum based polyamide 12 in many applications.

Polyamide 11 made from vegetable oil

In contrast to other high performance polyamides such as polyamide 12, Rilsan bioplastic polyamide 11 is derived from a renewable source: vegetable oil. In 2006, Rilsan polyamide 11 received the “Biomass Based” label from Japan Organics Recycling Association (JORA).

Eco-profile assessment provides valuable insight into the way PA11 performs environmentally compared to conventional performance plastics. Due to the fact that the starting feedstock is biomass, the consumption of fossil fuel is one of the lowest of performance polymers.

Greenhouse gas emissions for PA11 production are much lower than for all other performance polymers. The explanation for this feature is that PA11 production starts with a significant atmospheric CO₂ consumption (vegetal oil seed cultivation), leading to a reduction of CO₂ emission of up to 40%.

Bioplastic Rilsan PA11 for biodiesel fuel lines

Arkema’s Rilsan PA11 has been approved by several automotive manufacturers for biodiesel fuel lines in Europe and Brazil. Rilsan PA11 features excellent ageing resistance to biodiesel at high temperature, opening the way to the use of biofuels in automotive fuel lines.

Today’s increasing use of biofuels has led Arkema to develop a new Rilsan grade, BESN Noir P21OTL offers superior performance compared to polyamide 12, with outstanding chemical and mechanical ageing resistance at high temperature in particular.

The use of renewable source fuels such as biodiesel and flexfuel combined with the use of biobased Rilsan PA11 can significantly reduce greenhouse gas emissions.”Rilsan Polyamide 11 for Biofuel” received the “BioAward 2006” at the “Bioplastice 2006” conference in Frankfurt.

Arkema’s polyamide grades are well know for fuel lines in diesel cars. Rilasn has been the reference material for diesel fuel lines thanks to its resistance to high temperatures in under-hood environments for several years. Rilsan PA offers significant cost savings over traditional rubber or metal addition, biobased Rilsan PA11 can be paired with conductive Rilsan PA11 in a multilayer structure, such as Arkema’s Rilperm 2101 multilayer technology, to comply with Stangard SAE J1645 (Rilperm 2101).

Pilsan product range for quick connectors

Thermoplastic fuellines are connected through quick connectors. Rilsan PA11 and PA12 resins meet the demanding requirements for connectors used in automotive fuel contact applications. Both standard and conductive grades are available.

Arkema’s Rilsan polyamides and Rilperm fuel line technology allow customers to meet the most stringent standards and specification requirements in terms of fuel permeability, mechanical properties, and ageing resistance in increasingly demanding engine environments. The use of renewable source fuels suchas biodiesel and flexfuel combined with the use of biobased Rilsan PA11 can significantly reduce greenhouse gas emissions.

全球变暖及其他对环境的关心促使汽车工业进步以将当前汽车对环境的影响减到最小。政府法规如加州法令或欧4法规对燃油和尾气排放进行限制并向零排放水平逐渐加严。

使用可再生材料和燃料，如生物柴油和生物乙醇，可以显著降低温室气体排放和对化石燃料的依存度。使用替代发动机技术，如混合动力，可以进一步接近零排放汽车的目标。

将可再生燃料如生物柴油和灵活燃料同阿科玛公司的生物基Rilsan PA11综合使用可以显著降低温室气体排放。

高性能聚酰胺

阿科玛公司的高性能产品，如化石制品Rilsan聚酰胺12和生物基PA11，在运输业中被用作低渗透率管道中橡胶和金属的替代品已超过30年。

燃油管路和其他有严格安全性要求的应用场合对结构材料提出严格的强制要求。材料必须抵御化学制品、热和燃料的侵蚀，并承受车辆在生命周期的剧烈的温度变化。高性能聚酰胺的性质满足这些苛刻的要求

最终用户由抗腐蚀性、装配简易性和设计灵活性上获得收益，从而降低成本。Rilsan聚酰胺11具有出色的安全性、耐久性和多功能性，可满足更高的要求，在很多场合优于石化制品聚酰胺12.

植物油制成的聚酰胺11

相比于其他高性能聚酰胺，如聚酰胺12，Rilsan生物质聚酰胺11由可再生资源——植物油制成。2006年，Rilsan聚酰胺11获得日本有机资源协会(JORA)颁发的“生物基”标志。

环境特性评估就PA11相比于传统塑料更为环保的原因提供了有价值的见解。由于使用生物质作为原料，PA11是对化石燃料消耗最小的聚合材料之一。

PA11生产过程排除的温室气体远少于所有其他聚合物。这是由于PA11生产的源头会显著消耗大气中的CO₂（植物油种子栽培），从而使得CO₂排放量降低达40%。

生物塑料Rilsan PA11被多家汽车制造商在欧洲和巴西证明可用于生物柴油燃油管路。Rilsan PA11在高温条件下对生物柴油的抗老化性能出色，使其可用于车用生物柴油管路。

当前生物燃料使用的快速增长使得阿科玛公司开发新一代的转为生物柴油设计的Rilsan BESN Noir P210TL。生物燃料的腐蚀性远高于传统的石油燃料。Rilsan BESN Noir P210TL性能优于聚酰胺12，在高温条件下具有出色的抗化学和抗机械老化能力。

将可再生燃料如生物柴油和灵活燃料同生物基Rilsan PA11综合使用可以显著降低温室气体排放。在法兰克福举行的“生物塑料2006”会议上，“生物燃料用Rilsan聚酰胺11”获得“生物奖2006“。

阿科玛公司的聚酰胺产品作为柴油车燃油管路材料具有广泛的声誉。Rilsan由于可以持续多年抵抗发动机罩下的高温，而曾作为柴油机燃油管路的参考物质。同传统的橡胶和金属组装相比，Rilsan PA可以显著降低成本。此外，生物Rilsan PA基Rilsan PA11可以同导电Rilsan PA11以多层结构搭配使用，如阿科玛公司的Rilperm2101多层材料技术，从而满足SAE J1645标准的要求。

Rilsan用于快接接头的产品范围

热塑性塑料燃油管路使用快接接头进行连接。Rilsan PA11和PA12树脂满足车用燃油连接接头的要求。标准类型和导电类类型均可使用。

阿科玛公司的Rilsan 聚酰胺和Rilperm燃油管路技术使得消费者可以满足最严格的标准和不断严格的发动机环境对燃油渗透性、机械参数和耐久性的要求。将可再生燃料如生物柴油和灵活燃料同生物基Rilsan PA11综合使用可以显著降低温室气体排放。
