Unlike TPVs used for weatherproof seals in window frames, Monprene® IN-23000 Series styrenic block copolymer compounds are available in small lots and pre-colored grades. Some grades can be processed with same tooling used for PVC profiles at similar throughput rates and die pressures. TPEs resist staining from paints and exhibit end-use properties essential for air- and moisture-proof window gaskets, including rubberlike seal recovery, low-temperature toughness, and UV resistance.
