CSM Rubber Seals
Chlorosulfonated polyethylene (CSM) roj hmab seals engineered rau ib puag ncig xav tau kev tiv thaiv ozone, UV hluav taws xob, oxygen, thiab tshuaj corrosive. Unlike standard EPDM or neoprene, CSM elastomers cross-link via sulfonyl chloride groups, creating a dense molecular backbone that resists weathering, acid exposure, and moderate oil contact. Siv feem ntau nyob rau hauv sab nraum zoov, marine, thiab tshuaj ua cov khoom, cov profiles tuav elasticity thiab sealing quab yuam tshaj ncua kev pab cuam lifespan tsis nto tawg los yog hardening.
