The elastomer industry generally calls TPE SEBS modified by composite functional materials. TPE elastomer has excellent overall performance and is a soft material for molding and two-color injection molding processes. The main advantage of TPE encapsulation molding is that TPE material has good skid resistance and good elasticity, which can enhance the tactility of the product and is conducive to grip. TPE can be adjusted to appropriate hardness (Shore 25-90A) and appropriate physical properties (such as abrasion resistance, adhesion, melt index, etc.). Depending on product attributes, various possible material applications can be used for various products. TPE handles are overmolded and processed, and are usually used for handles, handles, electronic products and other products. This material gives the product a comfortable touch, enhanced grip, enhanced aesthetic feeling and added value. Most products are exported to developed countries and regions, such as the United States, Japan and the European Union. TPE elastomer is a soft and green material. The material does not contain phthalate and halogen. It conforms to ROHS environmental testing standards and can fully meet the environmental protection requirements of developed countries and regions, such as the United States, Japan and the European Union. Common TPE molding materials TPE can be used for overmolding and two-color injection molding. TPE is a soft material, usually matched with hard materials, mainly plastic, metal and fabric. TPE+fabric is mainly used for luggage products. This process is the same as metal overmolding, usually false overmolding. Real overmolding is more common in secondary and two-color injection molding. TPE can be firmly bonded with common plastics PP, GPPS, HIPS, ABS and engineering plastics PC, PC/ABS, PA and their modified materials. In the current elastomer industry! Adhesion between TPE and POM has always been a problem for you. Since the solubility parameter SP(22.6) of POM and SP(7.2-7.6) of TPE are very different, the two materials are incompatible with each other, and no suitable compatibilizer has been found to promote the adhesion of the two materials. However, through continuous research and development and experiments by Dechuang Chemical Factory, the problem of adhesion of TPE-coated POM has been improved. At present, the raw materials of TPE-coated POM produced by Dechuang Chemical Factory have been mature and applied in the market and have been recognized by customers. The hardness of this TPE-coated POM raw material is 60-70A. Due to the special formula of TPE-coated POM raw material, the hardness problem is also a point to be improved. However, we are also researching and developing to try our best to improve this defect and create more space for TPE-coated POM!
