SpletTENDLIN for iPhone 13 mini leather case is made of premium PU leather (not genuine leather) and high quality Thermoplastic polyurethanes (TPU), two materials synthesis of a one-piece case. Premium leather on the back offers unrivaled look and feel, that combine with shock absorbent TPU for reinforced toughness. TPU is the thermoplastic elastomer used in fused filament deposition (FFD) 3D printing. The absence of warping and lack of need for primer makes it an ideal filament for 3D printers when objects need to be flexible and elastic. Since TPU is a thermoplastic, it can be melted by the 3D printer's hotend, … Prikaži več 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 Prikaži več 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 … Prikaži več Table 1: Main differences between polyester- and polyether-based TPU. (A = excellent; B = good; C = acceptable; D = poor; F = very poor) Prikaži več TPU may contain siloxanes, some of which are considered substances of very high concern by the European Union. Prikaži več 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 with long-chain diols. By varying the ratio, … Prikaži več TPU has many applications, including automotive instrument panels, caster wheels, power tools, sporting goods, medical devices, drive belts, footwear, inflatable rafts, fire … Prikaži več Properties of commercially available TPU include: • high abrasion resistance • low-temperature performance Prikaži več
