Sealing & Gasket TPE | Weatherable, Elastic, Soft-Touch
Sealing & Gasket TPE – Overview & Applications
Weatherable, elastic TPE compounds for sealing strips, gaskets and soft profiles.
Chemdo offers SEBS/SBS-based TPE compounds for window & door seals,
appliance gaskets, industrial sealing profiles and
edge protection strips. These grades focus on elastic recovery, UV/weather resistance,
low fogging and soft-touch surfaces, suitable for extrusion and co-extrusion.
