Product Detail

polyurethane long glass fiber

Product Name:Thermoplastic urethanes TPU long glass fiber Granules pellets

TPU (Thermoplastic polyurethanes) name is thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type. It has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is widely used in daily necessities, sports goods, toys, decorative materials and other fields. Halogen-free flame retardant TPU can also replace soft PVC to meet environmental protection requirements in more and more fields.
The so-called elastomer refers to a polymer material with a glass transition temperature lower than the chamber temperature, an elongation at break> 50%, and good recovery after removal of external force. Polyurethane elastomers are a special category of elastomers. Polyurethane elastomers have a wide range of hardness and a wide range of performance. Therefore, polyurethane elastomers are a class of polymer materials between rubber and plastic.

It can be plasticized by heating. There is no or little cross-linking in the chemical structure. Its molecules are basically linear, but there is a certain physical cross-linking. This type of polyurethane is called TPU.

Three types
polyester type TPU, polyether type TPU and polybutadiene type TPU, which respectively contain ester group, ether group or butenyl group;
Performance
TPU+GF long glass fiber;various industrial fields: automotive manufacturing, paving materials, shock-absorbing cushioning materials, tanning, construction and other fields;high mechanical strength, good oil resistance; excellent chemical resistance; but the shortcomings of TPU materials are poor formability and relatively high cost.
Processing methods

TPU+GF ong glass fiber are injection molding and extrusion. The injection conditions are mainly related to the variety of raw materials, the shape of the product and the type of injection molding machine. In the process of injection molding, TPU is the first. The material is melted at a certain temperature, and then injected into the mold under a certain pressure, and rapidly cooled and shaped, which mainly bears the shearing force; because the TPU melt viscosity is high, the melting range is narrow, and the fluidity is Poor, this requires that the viscosity and morphology of the synthesized TPU must be constant, which makes TPU extrusion molding process performance requirements and injection molding TPU can be said to be completely different, they are less shearing This can form a completely uniform melt, making the surface of the product uniform and free of defects.

At present, since the beginning of the 21st century, with the advancement of the polyurethane industry and the expansion of the application of polyurethane, the research on TPU modification and modification methods will become more and more important and valued;
