PMHS

polymer

PMHS is a silicone-based polymer belonging to the polysiloxane family, characterized by a backbone of alternating silicon and oxygen atoms with organic side groups. It is primarily used in adhesives, sealants, coatings, and elastomeric applications where thermal stability, flexibility, and chemical resistance are required. PMHS is valued in industries demanding materials that remain functional across wide temperature ranges and can withstand exposure to oils, solvents, and weathering, making it a preferred choice over organic polymers in harsh environments.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
