Dryflex? 4057
热塑性弹性体
产品说明：
Due to their efficient processing, high performance and recyclability, Dryflex Thermoplastic Elastomers (TPEs) have made significant progress in proving themselves as a quality replacement for vulcanised rubber in window and door sealing applications.
Colour and co-extrusion possibilities have further enhanced the design possibilities for gaskets and seals made from TPE. New technologies such as Dryflex XP foamable TPEs and higher temperature resistant grades are providing materials which deal with design, performance and the environmental needs of the future.
We have supplied compounds for gaskets and weatherstrip extrusion for many years and are a trusted partner to the construction industry.
Today, we continue to develop technical material solutions to meet every application need. Some of the potential property spectrum and possibilities are shown below.
