PU and TPU this 2 types material using/adopting made as processing 科技完 full different, PU名称 is poly ester, types by use in rear in 底夹层 基于 foam large density resistant use material. to decrease function. TPU名称 is hot electrical plastics polyurethane ester 橡胶, this type of material can in hot degree lower soft, in normal temperature lower can maintain 不变. use in upper more stability, function.

 

PU polyurethane ester is types polymer/macromolecule material, polyurethane ester full is polyurethane acid ester, is upper has heavy 复氨基甲 acid ester large separation combined material 统称. it is has machine 二异氰 acid ester or more acid ester and 二羟基 or more 羟基化 combined material addition polymerization formed.

PU classification: hot solid property and thermoplastic property.
TPU就 is thermoplastic property polyurethane ester shrink 写. in inner is 习惯叫 method, many is PU pipe/tube ratio 如PU夹纱 tube/pipe,PU soft tube/pipe its is TPU即 thermoplastic property PU polyurethane ester is 原材.

1. hardness scope/range 广: through 改变TPU各 reaction separation ratio, can to different hardness product, but also hardness increase, its product still maintain good elastic property and wear resistance.

2. machine strong/high degree high: TPU products can force, impact resistant property and decrease property can 突出.

3. resistant property 突出: TPU 玻璃态转变 temperature degree comparison low, in lower 35 degree still maintain good elastic property, property and other physical properties.

4. processing properties good: TPU can using/adopting Common thermoplastic property material processing methods processing, injection molding, extrusion, calendering and other and other. meanwhile, TPU and certain polymer/macromolecule material processing can to property can polymer alloy.

5. oil resistant, resistant water, resistant 霉菌.

6. recycled utilizing property good.

TPU as is thermoplastic polyurethane (TPU), has polyester type and polyether type separation, it hardness scope/range wide (60HA-85HD), wear resistant, oil resistant, transparent, elastic property good, in day use product, use product, toys, decoration material and other field/area to application, flame retardant TPU also can soft 质PVC以 meet/satisfy 越 越 more field/area environmental protection requirements. TPU Brand grade more, quality 参差不齐, selection TPU时 most good detailed assessment 论证, if is can to property ratio most excellent 结果.
