Grilamid® L 20 HL Black 9563

Technical Datasheet | Supplied by EMS-Grivory (EMS Group)

Grilamid® L 20 HL Black 9563 is a medium viscosity, heat and light stabilized 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, high resistance to chemicals, hydrolysis, oil, termites, UV, abrasion and weathering. Possesses lowest density among all polyamides, low weight, high impact strength down at low temperatures, easy processability and high surface quality. Is suitable for processing by extrusion. Used in automotive applications like air intake-, compressed air-, fuel- and hydraulic systems, powertrain and chassis, outer sheathing layer of telecom cables, and in consumer good applications like hydraulics & pneumatics and engineering tools. Complies with REACH, RoHS and WEEE.
