TPU (thermoplastic polyurethanes) is named thermoplastic polyurethane elastomer rubber. TPU is a polymer material formed by the reaction and polymerization of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and other diisocyanate molecules with macromolecular polyols and low molecul......

PU film is polyurethane film. TPU film is thermoplastic polyurethane film. PU Film is a non-toxic and harmless environmental protection material, without any harm to human skin, and is widely used in clothing fabrics, medical care, leather and other fields.

As a kind of polymer material, plastic film has excellent electrical insulation, and static electricity is generated after contacting, rubbing and separating from objects. Normal plastic film is difficult to transfer the generated electric charge, electrostatic charge is accumulated on the surface, ......

PE film, polyethylene film. Polyethylene plastic film contains HDPE film, MDPE film, and LDPE film. LDPE film, low density polyethylene film, the density is about 0.92g/cm3. LDPE film has good transparency and heat-sealability, excellent waterproof and moisture-proof

The hardness of TPU plastic film is usually measured with Shore A and Shore D durometers. Shore A is used for softer TPU film material and Shore D is used for harder TPU film material. The higher hardness value, the higher the puncture resistance and wear resistance of the TPU film. The lower hardne......

PVC vinyl film has a slight absorption of blue in the short and medium wavelength range of visible light. PVC vinyl film roll looks yellowish or brownish by the naked eye, which affects its chromaticity and shows staleness. Therefore, ultramarine blue is necessary in the calandering processing of PV......
