extrusion stage TPE raw material manufacturer evaluates it in this way, TPE can be injection molded and extrusion molded . Extrusion molding can be continuously produced through the sink and cooled while extruding. As long as the material is continuous, it can be squeezed out continuously, and it can be tens of thousands of meters, without a material head. Below are two application cases of extrusion-grade TPE raw materials.
extruded grade TPE raw materials have the advantages of renewability, safety, non-toxicity, no odor, small density, good aging resistance, excellent high and low temperature resistance, excellent processing performance, good rebound performance, high tear resistance, and a service life of no less than 20 years, which is better than traditional PVC and EPDM glue strips. TPV and TPE have almost the same advantages and characteristics as TPE. The service life of TPE sealant strips is longer, so extruded grade TPE/TPV raw materials are the primary choice for making glue strips and are increasingly favored by the sealant strip market.
TPE glue strips are also called TPE sealing strips and TPE sealing strips, both of which are of the same meaning. Common glue strips on the market include PVC, EPDM, TPE, TPV and other materials. From an environmental perspective, TPE and TPV glue strips are more environmentally friendly and non-toxic. In terms of performance, TPE and TPV rubber strips perform better. The TPV substrate is an elastomer blended with EPDM and PP, so it is better than TPV rubber strips than EPDM. From a cost-based perspective, the glue strips made of TPE and TPV are more cost-effective because they are both thermoplastic elastomer , and the waste can be recycled and recycled, reducing the production costs of enterprises.
extrusion grade TPE raw material is used to produce headphone lines. It mainly has the smoothness of TPE material, the tensile strength of rubber composites and excellent coloring properties: the pigment is evenly dispersed, no flow marks, no fading, rubber and core. Adhesion has its requirements. Therefore, the TPE compound used to produce extruded headphone wires, especially relatively advanced headphone wires, is more refined in their formulation and physical properties. In terms of hardness, the headphone wire material is usually a TPE compound with a hardness of 65 to 80 degrees ShoreA. For the appearance of the outer layer of the headphone cable, there are two types of surface gloss and matte.
In addition to the physical properties similar to PVC, TPE compounds can also reach the EU halogen, phenylene 16P, nonylphenol NP, and Pahs environmental testing content standards. Therefore, TPE environmentally friendly materials have been widely used in the headphone wire industry in recent years.
