Description
VMQ is based on a siloxane backbone, offering excellent heat resistance and good low-temperature flexibility. It provides outstanding ozone and aging resistance, excellent electrical insulation, and is non-toxic and odorless. Although tensile strength is relatively low, it can be improved through reinforcement. Widely used in food machinery seals, medical tubing, and electronic insulation components. WINBEST can tailor formulations according to customer requirements.
Applications
Oven door seal
Medical infusion tube gasket
Pressure cooker sealing ring
Electronic keypad / button
