Polybutylene Terephthalate
Marplex Australia Pty. Ltd.
30% 玻璃纤维增强材料
产品说明：
ASTADUR™ B4300G6 is a 30% glass fibre reinforced, UV stabilized grade of polybutylene terephthalate (PBT) polymer. It has excellent processability, high rigidity and heat resistance and is resistant to chemical attack. It is suitable for applications where rigidity and heat resistance are of high importance.
Note: The letters "UV" or "W" indicate UV stabilisation has been added [ ie: ASTADUR™ B4300G6UV ].
