The present invention, based on 100 parts by weight of a rubber elastomer comprising an ethylene-propylene-diene monomer (EPDM) and an ethylene-propylene monomer (EPM), comprises 80 to 100 parts by weight of a paraffinic oil, 2 to 15 parts by weight of a crosslinking activator, 0.3 to 9 parts by weight of a crosslinking accelerator, 0.5 to 3 parts by weight of a crosslinking agent, 2 to 4 parts by weight of a foaming agent, and 1 to 10 parts y weight of a moisture absorbent, wherein the foaming agent comprises a capsule foaming agent and a chemical foaming agent, and has a constitution in which the capsule foaming agent and the chemical foaming agent are mixed at a weight ratio of 0.5 to 1.5: 0.5 to 1.5. The low density weather strip composition has a low density and has excellent rigidity and processability.

    본 발명은 에틸렌-프로필렌-디엔 모노머(EPDM) 및 에틸렌-프로필렌 모노머(EPM)를 포함하는 고무탄성체 100중량부에 대하여, 파라핀계 오일 80~100중량부, 가교활성제 2~15중량부, 가교촉진제 0.3~9중량부, 가교제 0.5~3중량부, 발포제 2~4중량부 및 흡습제 1~10중량부를 포함하고, 상기 발포제는 캡슐발포제 및 화학발포제를 포함하고, 상기 캡슐발포제 및 화학발포제는 0.5~1.5:0.5~1.5의 중량비로 배합되는 구성을 마련한다. 상기와 같은 저비중 웨더스트립 조성물은 저비중이면서도 강성 및 가공성이 우수하다.
