Twintex ®
Twintex ®是一种独特的,可以直接使用的热塑性玻纤增强材料,具有优异的机械属性,如良好的刚度/重量比和卓越的冲击性能等。 Twintex ®还有助于实现高效环保的工艺条件以及设计的高度灵活性,并可回收利用。
Twintex ®产品的原材料为无碱玻璃和热塑性纤维。
直接粗纱是整个Twintex®产品线的基础材料,目前也可提供基于聚丙烯(PP)与共聚PBT(co-PBT)的产品。
Twintex ®产品系列还包括织物、面板、长玻纤浓缩颗粒等。不同产品的玻璃纤维含量不同。
PP热塑性产品系列参数 玻璃纤维重量%
纱线 Twintex R聚丙烯 60 %或82 %
织物Twintex Ť聚丙烯 60 %
面板Twintex P聚丙烯 60 %
长纤母粒Twintex TP PP 75 %
目前,共聚酯热塑配方主要用于Twintex ®粗纱R co-PBT,玻璃纤维含量为65 %。
| 产品参考清单 |
| TWINTEX® R PP | TWINTEX® R PP is a roving made of commingled E-glass and polypropylene filaments. TWINTEX® R PP is suitable for filament winding, pultrusion, reinforcement of extruded profiles and weaving. Consolidation is done by heating the roving above melting temperature of PP matrix (180°C–230°C / 360°F-450°F) and applying a pressure before cooling step under pressure. |  |
| TWINTEX® T PP | TWINTEX® T PP is a fabric made of TWINTEX® roving (commingled E-glass and polypropylene filaments). Consolidation is done by heating above melting temperature of PP matrix (180°C-230°C / 360°F-450°F) and applying a low pressure (1-30 bars), before cooling step under pressure. |  |
| TWINTEX® P PP | TWINTEX® P PP is a consolidated plate based on TWINTEX® fabrics. TWINTEX® P PP is processed by in-mold pressure after heating above melting temperature of PP matrix: 180°C–230°C (360°F- 450°F). |  |
| TWINTEX® TP PP | Twintex® Long Glass Fiber Concentrate / PP Pellets (TP PP) are obtained by pultrusion of Twintex® TR PP rovings They are coated with a plastic blend that protects them during transport and that can contain application- specific additives package as per the applications requirements the product has to fulfil. TWINTEX® TP PP is mainly used to produce injected TP parts requiring structural performances like impact, or mechanical performances in Temperature exposition. |  |
| TWINTEX® R coPBT | TWINTEX® R coPBT is compatible with PVC for reinforcement of extrusion. It’s also suitable for filament winding and pultrusion. Consolidation is done by heating the roving above melting temperature of coPBT matrix (180°C–230°C) and applying a pressure before cooling step under pressure. |  |
