Grilamid® L 25 W 20

Grilamid® L 25 W 20 is a semi flexible, plasticized, high viscosity polyamide 12 (PA 12) grade. Is formed by the polymerisation of laurolactam (lactam 12, obtained from the basic raw material butadiene), a ring-shaped, long-chain monomer with 12 carbon atoms. Exhibits low water absorption, excellent dimensional stability, good UV- and heat stability, high resistance to chemicals, hydrolysis and weathering. Possesses lowest density among all polyamides, low weight, good impact strength at low temperatures and easy processability. Is suitable for processing by extrusion. Used in automotive semi-flexible tubes & profiles and in hydraulics & pneumatics. Complies with REACH, RoHS and WEEE.
