FAQ

FAQ About Glass-filled PA66 Thermal Profiles

Q: Why choose PA66GF25 over PVC for thermal barriers?

A: PA66GF25 has a thermal expansion coefficient close to aluminum alloy, preventing joint failure under thermal stress, while PVC has poor high-temperature resistance and large thermal deformation, leading to short service life.

Q: How does 25% glass fiber reinforcement benefit the product?

A: 25% glass fiber boosts tensile strength by 60% and heat resistance to 230°C, enabling post-spraying processes and enhancing the product’s dimensional stability.

Q: How do GF25 Reinforced Polyamide 66 Strips achieve energy savings?

A: With a low thermal conductivity of 0.3W/(m·K), it blocks 90% of heat transfer between aluminum profiles, cutting building energy loss by 40% and improving thermal regulation efficiency.
