and offers increased safety in use.

Flame retardant polyamides help reduce flammability, helping to make products safer and comply with the highest fire safety standards.

● Impact modifiers
Impact modifiers are added to polyamides to increase their impact resistance and toughness. This modification is beneficial for applications that require high durability and impact resistance, such as automotive components, industrial parts, and consumer goods.

Impact modified polyamides exhibit increased toughness, hong kong data crack resistance and durability, ensuring long-lasting performance even under harsh conditions.

PA 6 and PA 66
PA 66: offers better thermal stability and slightly superior mechanical properties than PA 6.
AP 11 and AP 12
PA 11: low moisture absorption, good resistance to impact and chemicals.
PA 12: similar to PA 11 but with better dimensional stability and less UV resistance.
