Polyamide 12 - Nylon 12 - PA 12 30% Glass Fibre Reinforced

Aug 29 2001

Polymer Type

Thermoplastic

Advantages

Good rigidity, tensile strength, creep resistance, heat distortion temperature and impact properties. Low mould shrinkage and good dimensional stability compared with unmodified PA 12.

Disadvantages

Brittle, low elongation at break and low impact strength compared with unmodified PA 12. Mechanical properties of moulding can be highly anisotropic.
