HYTREL 5555HS

HYTREL 5555HS is a popular thermoplastic elastomer of polyester that is considered a suitable alternative for plastic, rubber, and metal in many applications. This elastomer combines the properties of flexible plastic and high-performance elastomers. Owing to their resistance to chemicals and exceptional durability, this elastomer has become a common choice for sealing solutions to be used in various challenging industrial applications. 

At SSP Seals, we specialize in sealing solutions using various types of thermoplastics and HYTREL is one of them. We regularly build sealing elements including backup rings and wipers using this material. It exhibits excellent aging properties at high temperatures.
