- This product contains 50% glass fibre. The addition of glass fibres improves the heat deflection temperature, allowing the material to withstand higher temperatures before deforming under load.
- Glass-reinforced nylon has greater tensile strength, stiffness and impact resistance than unreinforced PA66.
- The composite also possesses superior hardness, surface durability, and wear resistance compared to PA66.
- Socket head bolts are tightened and loosened with a hex key. Also known as socket cap screws, hex socket screws.
Product Summary
This product contains 50% glass fibre. While the melting point remains largely unchanged, the heat deflection temperature of PA66+GF (glass fibre reinforced PA66) is superior to that of PA66, meaning that the composite can withstand higher temperatures before beginning to deform under load. The composite exhibits reduced moisture absorption, a significant improvement over PA66's susceptibility to moisture. Common applications include automotive components, industrial machinery and consumer goods where high strength and thermal resistance are required. Socket head bolts are also known as socket cap screws.
