Technical Datasheet PA12 L20L

Product Description:

Grilamid L 20 L is a medium viscosity Polyamide 12 (PA12) extrusion type. It is UV and heat stabilized. Its main features are high surface quality, very good UV and heat resistance, high abrasion resistance, good chemical and oil resistance, low weight, and low density.

Applications:

Grilamid L 20 L has been especially developed for high speed extrusion of thin walled primary copper wire insulation and secondary fiber optic cable sheathing as a protection against termites and ants.
