TPU material in three kinds of material is super wear resistance, excellent wear resistance and yellowing resistance makes the advantages of this kind of material is very outstanding.
The talk page may contain suggestions. (September 2010). 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. TPU soft characteristics between rubber and plastic, TPU hardness range is wide, by changing the TPU ratio of each reaction component can get different hardness of products, and with the increase of hardness, its products are still keep good elasticity and abrasion resistance. TPU material in three kinds of material is super wear resistance, excellent wear resistance and yellowing resistance makes the advantages of this kind of material is very outstanding. Taken together, the physical properties of TPU are relatively prominent, but each has a protective shell has its own advantages. A TPU is a multi-phase block copolymer that is created when three basic raw materials are com-bined together in a specificway. The individual components required to produce a TPU are:• A polyol or long-chain diol• A chain extender or short-chain diol• A diisocyanate Figure 1.0 depicts the basic chemistry of TPU. CellPig.com explains what a TPU silicone rubber case is and describes all of their benefits. They then throw the phone from a moving vehicle onto the pavement and test to see if the gadget still works. The video finishes up with a slide show of TPU covers that are sold at CellPig.com. Elastomeric materials like TPU are differentiated by hardness. A durometer instrument is used to measure surface hardness for the Shore-A and Shore-D scales, the Shore-A scale being softer and the Shore-D scale being harder. Typically, TPUs are made in the 70A to 75D hardness range. PC material protection case. PC material protection case light transmittance is also very good, pure PC plastic have a pure and transparent, transparent black transparent blue wait for all sorts of color, are all very well.
