EMS-Grivory Grilamid® L 20 LM PA12
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 12 (PA12)
Material Notes:	Product Description: Grilamid L 20 LM is a medium viscosity Polyamide 12 (PA12) extrusion grade. Grilamid L 20 LM is UV and heat stabilized and has been modified with a nucleation agent which results in a low post crystallization and low post shrinkage. The special features of this product are: UV and heat stabilized High abrasion resistance Very good chemical resistance Very good resistance to oil High surface quality Good dimensional stability High processing speeds Low density, low weight Application examples: Grilamid L 20 LM is especially suitable for high speed extrusion of thin walled sheathings for applications such as copper wire insulation or secondary tight coating of optical fibers providing resistance against attack from termites and ants.
