| 中文摘要: |
| 简介近几年乙丙橡胶新品种及改性技术、应用技术进展。乙丙橡胶新品种有5-乙烯基-2-降冰片烯（VNB）-三元乙丙橡胶（EPDM）、可控长链支化EPDM、双峰相对分子质量分布EPDM、液体乙丙橡胶和四元乙丙橡胶等。乙丙橡胶的改性有化学改性、共混改性、增强改性等。乙丙橡胶在中高压橡胶绝缘电缆、高耐热输送带、汽车传动带、汽车密封条和汽车散热器胶管中的应用越来越广泛，应用技术日益成熟。 |
| 英文摘要: |
| The development of new grades and application technology of ethylene propylene rubber in recent years is summarized. The 5-vinyl-2-norbornene EPDM (VNB-EPDM)， controlled long-chain branched EPD bimodal EPDM， liquid EPDM and quadripolymer EPDM are introduced. The modification technologies of ethylene propylene rubber include chemical modification， blending and reinforcement. Ethylene propylene rubber is more and more widely used in applications such as rubber insulation in medium to high voltage cable， high heat-resistant
conveyor belt， automotive belt， automotive sealing and automotive radiator hose. |
