| Extron 300 GF HS is a 30% glass fibre reinforced homopolymer polypropylene compound. It is a low flow injection moulding grade developed for rigid components requiring high heat deflection temperatures, excellent creep resistance and low mould shrinkages. It is stabilized to meet automotive heat ageing requirements of 500hrs at 150°C. |
