聚丙烯酸酯聚合物(ACM)是一种特种弹性体,其耐高温和耐油性能较好,主要用在耐高温和耐油制品上。这类弹性体应用在汽车方面极其优越,能够提高长时间的耐高温性能,在阀盖垫圈、油封垫圈、摇杆盖垫圈和其他各种密封方面已经得到证实。它具有极好的耐长时间高温性能、极好的压缩变形性能、耐压缩应力松弛(CSR)以及弹性体本身提供的稳定的定伸应力。最近开发出的新产品更是提高了挤出加工性能,因此可被用于胶管中。介绍了丙烯酸酯橡胶在挤出加工时具有较长焦烧时间的优势,并且其硫化性能容易控制,与目前采用的高温解决方案相比成本优势明显。这种材料可以满足许多高温应用领域制品的需求。
Polyacrylate polymer (ACM) is a specialty elastomer with good high temperature and oil resistance properties and is mainly used in high temperature and oil resistant products. These elastomers are extremely automotive-friendly and provide long-term high-temperature resistance. They have been demonstrated in bonnet gaskets, gaskets, rocker cap gaskets and various other seals. It has excellent resistance to extended periods of high temperature performance, excellent compression set, compressive stress relaxation resistance (CSR) and stable set stress provided by the elastomer itself. The recent development of new products is to improve the extrusion processability, it can be used in the hose. The advantage of long scorch time of acrylate rubber during extrusion is introduced and the vulcanization performance is easy to control. The cost advantage is obvious compared with the existing high temperature solution. This material meets the needs of many high temperature applications.
