FLP Swedish Greenseal Rubber (EPDM)
FLP Greenseal Rubber EPDM (ethylene propylene diene terpolymer) is a synthetic rubber similar to butyl and manufactured in Sweden by Trelleborg Building Systems – who also manufacture butyl rubber. As a material, Greenseal Rubber has superior properties to Butyl and cheaper, making it both an attractive and economical solution for any project. Benefits compared to butyl of equivalent thickness– Lower cost both initially and long-term– Higher UV stability– Greater tolerance to weather extremes– Superior Strength– Lower environmental impact The following table lists some physical comparisons between the two 0.75mm materials; Properties Greenseal ButylTensile strength 9.0Mpa 7.5MpaTear strength 30KN/m 20KN/m
