LWRT & GMT lines
Lightweight reinforced thermoplastics (LWRT) and glass mat thermoplastics (GMT) are prepreg fabrics, already impregnated with a thermoplastic resin before the molding process begins. Because it is a thermoplastic material, it is easier to recycle as reheating it will separate it from the fiber. To process these materials they must first be heated to high temperatures (about 200°C), then moved quickly to the press for shaping before they cool down. The forming mold is relatively cold (about 60°C), helping to solidify the resin once the material has acquired the desired shape.
