赢创是世界最大的聚酰胺12(PA12)——VESTAMID® L生产商之一。这受益于我们一体化的生产过程： 从丁二烯开始，赢创通过多步加工生产出PA12的单体月桂内酰胺。 赢创的VESTAMID® L化合物包括多种不同的定制产品，可以满足加工商和最终用户的要求。 

半结晶聚酰胺的性质取决于大分子中酰胺基团的浓度。 相比市场上其它聚酰胺，PA12中的酰胺基浓度最低，这也造就了PA12的独特性能： 

ont-size: 12pt;">• 最低吸湿率： 在湿度改变的条件下，注塑件显示出最佳的尺寸稳定性。 
• 即使在远低于凝固点的温度下，仍保持杰出的冲击强度和缺口冲击强度 
• 良好的脂、油、燃料、液压液、各种溶剂、盐溶液和其它化学品耐受性能 
• 杰出的抗应力开裂能力，即便是在含金属嵌件的注塑或塑料部件中 
• 优良的抗磨损性 
• 在钢、聚对苯二甲酸丁二醇酯、聚缩醛及其他材料上干运行时，滑动摩擦系数低 
• 降噪及减振特性 
• 在高频循环负载条件下，杰出的抗老化性 
• 优异的加工性 

凭借这些特性，VESTAMID®L可应用于诸多领域，包括汽车的精密管路系统、原油开采过程中的大容量油管、电缆行业中的导线绝缘、医疗用导管、以及机械与工程领域中齿轮和阀套的精密注塑部件。
