TECAMID 66 LA natural

PA 66 LA natural

TECAMID 66 LA natural is a PA 66 material benefiting from an added solid lubricant. The solid lubricant in the PA 66 improves the sliding friction properties, as well as the abrasion behaviour compared to standard TECAMID 66 (unfilled polyamide 66). However as a consequence, the additive causes the material to exhibit slightly lower strength, rigidity and hardness characteristics.
