Material characteristics

PU
(U203-G95, PUR, Ecopur)

Thermoplastic polyurethane elastomer. It is characterised by high abrasion resistance, low permanent deformation factor under compression, a high resistance to break. It is used mainly in self-sealing lip (groove) rings, scrapers, self-sealing chevron rings and special seals. In practice, this material is also used for other technical profiles.
