What test factor influence the deviation of TPU hardness
Jun 24 , 2022
Compared with other plastics, hardness is a more important properties for TPU granule. TPU hardness is generally tested by the Shore hardness tester. Shore hardness divided into Shore A and Shore D, which represent different hardness ranges. TPU hardness below 90A test by Shore A hardness tester, TPU hardness above 90A test by Shore D hardness tester. Although the hardness test is relatively simpl...

What is TPU Storage conditions
Jul 01 , 2022
TPU is easy to absorb moisture from environment and excessive moisture content in the granulate can lead to processing problems and to a reduction in the quality of the finished part. The moisture might bring about partial degradation of polymers and the formation of bubbles or streaks in the molded and extruded parts. Koslen TPU resins are packed in 25kg moisture proof bags. All Koslen TPU resins...

Is TPU the same as PU
Jul 08 , 2022
TPU stands for thermoplastic polyurethane and is thermoplastic transparent granule which can be meltdown when heated. TPU is a block copolymer consisting of alternating sequences of hard and soft segments. The proportion of hard and soft segments can be manipulated to produce a wide range of hardness. Different ratio of hard to soft segments will result in different hardness TPU and can be as soft...
