乙烯-丙烯-非共轭二烯烃三元共聚物(EPDM)

推动更好、更具可持续性的橡胶

乙烯-丙烯-非共轭二烯烃三元共聚物,简称EPDM,是一种可以承受最恶劣环境条件的耐用材料。它可以承受高温和腐蚀性化学品。我们的EPDM产品更洁净,更易于使用,并能实现高效生产。

NORDEL™ EPDM产品具有业内最丰富的乙烯含量。这些高品质、几乎不含凝胶的聚合物 - 包括超高分子量和充油级别产品- 是一系列汽车、建筑、消费品和其他应用的理想选择。NORDEL™ EPDM产品形式包括块胶和颗粒胶料,我们正在逐步扩展新产品系列,可满足特定客户和行业的需求。

与传统的EPDM不同,我们的EPDM采用专有的先进分子催化剂(AMC)技术,通过溶液法工艺生产,使其具有非常独特的性能和优点:

优势技术

AMC技术可实现EPDM分子结构的定制化设计,包括更好地平衡加工性能和物理特性。这项独家技术的主要优点包括:

  • 丰富的聚合物属性
    • 超高分子量
    • 更宽的分子量分布
    • 高二烯含量
    • 极低到极高的聚合物门尼粘度
    • 充油级别产品
    • 多种乙烯含量,从无定形到半结晶
    • 更高的长链支化能力
    • 超洁净、极低的凝胶含量
  • 加工效率
    • 高生产力
    • 快速混炼和加工
    • 快速硫化
    • 填充能力更强
    • 挤出和注射发泡
    • 填料和添加剂的分散更快更好
    • 废料减少

 

跨应用的EPDM

NORDEL™ EPD适合非常广泛的应用:

  • 运输/汽车:车身车门密封、软管和皮带、模压橡胶制品和轮胎
  • 建筑/基础设施:防水膜、建筑型材、地板覆盖物、管道密封、隔热泡沫和桥梁衬垫
  • 消费品:运动和休闲设施的表面材料、自行车轮胎、器具软管和密封件、花园软管和高性能鞋材
  • 热塑性改性:热塑性动态硫化橡胶(TPV)、热塑性聚烯烃(TPO)
  • 油和润滑剂:油粘度指数改进剂(OVII) (OVII)

绩效和可持续性

使用AMC技术生产的NORDEL™ EPDM的生命周期分析表明,它比使用Ziegler-Natta催化技术生产 EPDM具有更小的环境影响,(1) 包括:

  • 能源需求减少20-25%
  • 各类别的整体改善
    • 烟雾减少45%
    • 对臭氧消耗的影响减少69
    • 富营养化减少55%
    • CO2 排放减少39
    • 酸化率减少37%

如果您有任何EPDM方面的需求,敬请随时联系我们。让我们紧密合作,帮助您选择适合您需求的理想产品。
