overview: mainly divided into polyester type and polyether type, ithas a wide range of hardness (60ha-85hd), wear resistance, oilresistance, good elasticity, it is widely used in the field ofdaily necessities, sporting goods, toys, decorative materials andother fields, halogen flame retardant tpu can also replace soft pvcto meet the environmental re of more and more fields. theso-called elastomer refers to the vitrification temperature islower than the chamber temperature, elongation at break >50%,after the removal of external forces recovery ratio of polymermaterials. polyurethane elastomers are a special category ofelastomers. polyurethane elastomers have a wide range of hardnessand properties, so polyurethane elastomers are a kind of polymermaterials between rubber and plastic. thermally plasticized, withlittle or no chemical crosslinking, the molecules are essentiallylinear, but there is some physical crosslinking. this type ofpolyurethane is called tpu.tpu 392 characteristics: wide range ofhardness: products of different hardness can be made by changingthe ratio of each reaction component of tpu, and with the hardness,the products still maintain good elasticity and wearresistance.high mechanical strength: outstanding bearing capacity,impact resistance and shock absorption of tpu products.coldresistance of tpu: the glass transition temperature of tpu isrelatively low, and it still maintains good elasticity, flexibilityand other physical properties at -35 ℃.good machining performance:tpu can be processed by common thermoplastic materials, such asinjection molding, extrusion, rolling, etc. at the same time, tpuand some polymer materials can be processed together withcomplementary properties of polymer alloys. resistance to oil,water and mold. good reusability. as an elastomer, tpu is amaterial between rubber and plastic, which can be seen from itsrigidity. the rigidity modulus of tpu is measured. the elasticmodulus of rubber is usually 1~10mpa, tpu is 10~1000mpa, andplastic (nylon, abs, pc, pom) is 1000~10000mpa. the hardness rangeof tpu is quite wide, from shore a 60 to shore d 80, and has highelasticity in the whole hardness range. tpu is flexible and doesnot require plasticizer in a wide temperature range of -40~120℃;tpu has good resistance to oils (mineral oils, animal fats andoils) and many solvents; tpu also has good weather resistance andexcellent high energy ray resistance. known wear resistance,resistance, flexion strength are excellent; high tensile strength,high elongation and low compression deformation rate are allsignificant advantages of tpu.
