Polyamide - Nylon 6/6 30% Glass Fibre Reinforced - Supplier Data by Goodfellow

Background

The addition of glass fibre to nylons leads to very significant increases in strength, stiffness, heat distortion temperatures, abrasion resistance and dimensional stability, though properties can be anisotropic - including mould shrinkage, leading to potential distortion.

In the case of Polyamide – Nylon 6/6 30% Glass Fibre Reinforced - unlike many polymers - this is achieved without loss of impact strength, though elongation to break is, as usual, reduced very substantially. Glass-reinforced nylon is commonly coloured black.

Applications

Applications of Polyamide – Nylon 6/6 30% Glass Fibre Reinforced include many engineering components such as "under-bonnet" automobile parts and most components on wind-surfers.
