본 발명은 웨더스트립 스폰지용 EPDM 고무 조성물에 관한 것으로, 더욱 상세하게는 무늬점도 (MLat 125℃) 값이 90 이상이고, 5-에틸리덴-2-노보넨 (ENB)함량이 9 중량% 이상인 EPDM 고무에, 유리 황(free sulfur)과 1,6-비스(N,N-디벤질티오카르바모일디티오)-헥산 (BDBzTH)가 포함되어 있는 EPDM 고무 조성물에 관한 것이다. 본 발명의 EPDM 고무 조성물은 압축 영구변형율 (Compression set)의 개선효과 및 EPDM 고무의 고질적인 변색 문제를 해소하는 효과를 가지므로, 자동차의 웨더스트립 스폰지 부분의 소재로 유용하다.
An ethylene-propylene-diene monomer (EPDM) rubber composition for a sponge in a weather strip is provided. In the EPDM rubber composition free sulfur and 1,6-bis(N,N-dibenzylthiocarbamoyldithio)-hexane (BDBzTH) are included in a EPDM rubber having a pattern viscosity (ML 1+8 at 125°C) value of 90 or more and a content of 5-ethylidene-2-norbornene (ENB) of 9 wt% or more. The EPDM rubber composition can improve compression set and provides a solution to the persistent discoloration problem of the EPDM rubber. Provided herein are EPDM compositions that are useful as a material of a sponge section in a weather strip of a passenger car.
