WebbTPU vs. PU Main Difference. The main difference between TPU and PU is that TPU is a type of thermoplastic elastomer and is known for its property of being elastic and melt-processable, whereas PU is composed of urethane linkages and are known for temperature bearing abilities as they do not melt when are subject to high temperatures. Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments. Visa mer TPU is a block copolymer consisting of alternating sequences of hard and soft segments or domains formed by the reaction of (1) diisocyanates with short-chain diols (so-called chain extenders) and (2) diisocyanates … Visa mer TPU has many applications, including automotive instrument panels, caster wheels, power tools, sporting goods, medical devices, drive belts, footwear, inflatable rafts, fire … Visa mer Table 1: Main differences between polyester- and polyether-based TPU. (A = excellent; B = good; C = acceptable; D = poor; F = very poor) TPU is the right choice when a flexible at low temperatures and/or abrasion resistance Visa mer A TPU resin consists of linear polymeric chains in block-structures. Such chains contain low polarity segments which are rather long (called soft segments), alternating with shorter, high polarity segments (called hard segments). Both types of segments … Visa mer Properties of commercially available TPU include: • high abrasion resistance • low-temperature performance Visa mer TPU may contain siloxanes, some of which are considered substances of very high concern by the European Union.
