Prima introduces a low-hardness TPE suitable for window sealing

Thread Content

Recently, PolymaxTPE has developed a low-hardness thermoplastic elastomer named D6940, whose performance is superior to that of thermoplastic vulcanized rubber (TPV), which is widely used in window sealing. D6940 has high tear strength, can undergo permanent deformation under low compression, and is cost-effective. D6940 is highly suitable for window seals that require low-stress deformation, rubber seal recovery, as well as resistance to ultraviolet rays and stains and paints. Even when the hardness of D6940 is reduced to 40° Shore, its tensile strength remains 12% higher than that of TPV with a hardness of 60° Shore; it also exhibits a lower compression set of 14% higher than that of TPV at 23°C, as well as a tear strength that is 12% higher than that of TPV at 70°C. According to Tom Castile, deputy director of sales at PolymaxTPE, \"To meet the growing demand for soft TPE elastomers in the markets for window seals and telecom enclosures, this new TPE material achieves high tear strength along with low compressive set at a low hardness of 40 Shore.” ” “Although D6940 serves as a cost-effective alternative to TPV elastomers, it still exhibits better low-temperature toughness in door and window seals compared to soft polyvinyl chloride, said Dr. Ron Sheu, Vice President of New Business Development at Polymax TPE.
