Key Advantages of PA66 GF20 FR(V0)
Optimal Safety-Performance Balance:
Combines meaningful mechanical reinforcement (20% GF) with guaranteed UL94 V-0 flame retardancy, offering a superior solution over non-reinforced FR grades.
Enhanced High-Temperature Capability:
Inherits PA66’s high melting point, with a Heat Deflection Temperature (HDT) typically above 245°C, ensuring stability in under-hood and high-heat electrical environments.
Improved Dimensional Stability & Strength:
The glass fiber reinforcement significantly increases stiffness and reduces moisture absorption compared to unreinforced FR nylon, leading to more reliable and precise components.
Excellent Chemical Resistance:
Maintains good resistance to oils, greases, and many chemicals, making it suitable for demanding automotive and industrial applications where fire safety is also required.
