Product details
TPE is used for adhesive coating and shot bonding. TPE soft adhesive is used as the outer coating of soft adhesive. Common hard materials matched with TPE are mainly plastic, metal and woven fabric. TPE and woven fabric are mainly applied to luggage products. Like metal encapsulation, TPE and woven fabric are generally fake encapsulation. True encapsulation is commonly found in secondary injection molding and two-color injection molding, that is, the main material of TPE encapsulation is plastic. TPE can be firmly bonded with common general plastics PP,GPPS,HIPS,ABS and engineering plastics PC,PC/ABS,PA and their modified materials.
How to choose the hardness of TPE coating? The hardness of TPE coating and TPR coating varies with the different base materials and the requirements of using physical properties. If it is wrapped in PP(TPE wrapped in PP, TPE wrapped in PP, TPR wrapped in PP), TPE, TPR is about 30-60A, while the hardness will be higher if it is wrapped in polycarbonate (PC), nylon (PA6) and ABS. Also look at the use, such as children's toothbrush is soft, bicycle grip, pen holder, golf club grip, sports equipment grip is slightly higher, while the larger force screwdriver, rubber is hard, there are some metal, rubber stainless steel, hardness of about 80A .. At the same time, men exert more force than women, and adults exert more force than children, so the hardness is greater.
Hardness of TPE is defined as the dent resistance of the material when static load is applied. Hardness is also related to other important physical properties, such as tensile modulus and flexural modulus. Due to various measurement scales and hardness and the relationship with other material properties, confusion may occur when discussing hardness. When selecting a thermoplastic elastomer (TPE), the hardness of the material is often one of the first indexes to be considered. Thermoplastic elastomer (TPE) can produce standard products with hardness ranging from Shore A0 (softest) to Shore A95 (hardest).
TPE coated elastomer soft rubber can be adjusted to appropriate hardness (hardness range Shore 25-90A) and appropriate physical properties (such as abrasion resistance, scratch resistance, cohesiveness, melt index, etc.) according to the physical property requirements of the product. Various possible material application schemes are provided for different products.
