TPR material (Thermo-Plastic-Rubber material) is a thermoplastic rubber material. Is a type of rubber elasticity without vulcanization, can be directly processed molding (e.g. injection molding, extrusion, blow molding, etc.) thermoplastic soft adhesive.
Rubber elasticity and good wear resistance, anti-slip and shock absorption performance is excellent, TPR material soft comfort is superior to rubber, but material tensile strength, fatigue resistance and mechanical properties are not as good as vulcanized rubber.
- The use of temperature range -45 to 90 degrees C. Generally speaking, TPR material is based on SBS substrate, its chemical properties are as follows: weather resistance, aging resistance in general, temperature resistance 70 to 75 degrees C. If the need for good aging resistance to temperature materials, can choose the SEBS substrate modified materials.
- Hardness characteristics, TPR material can be in the Shore hardness 5 to 100 degrees to adjust its hardness, SEBS as the substrate of the modified material can be adjusted to a lower hardness.
- Processing characteristics, TPR materials and some glue, ink, etc. have good bonding properties, with good injection silk screen processing.
- Environmental protection characteristics, TPR material as an environmentally friendly soft glue, the main hazardous substances such as plasticizer phthalates Phthalate, phenyl phenol NP, polycyclic aromatic hydrocarbons PAHs testing, in line with ROHS, REACH, EN71-3, ASTMF963 environmental testing standards.
