Why should TPU resin be dried before processing?
Oct 14 , 2022
The linear TPU natural plastic molecule contains many strong polar groups (such as ester group, ether group, carbamate group, urea group, biuret group and allophanate group, etc.), The strong forces between the molecules of these groups and the hydrogen bonds form physical cross-links. TPU molecular structure determines that TPU plastic resin is easy to absorb moisture after be exposed in the air....

Why are TPU resin granular?
Aug 26 , 2022
Except for semi-finished TPU are blocks, most TPU on the market are granular. The shape of TPU particles usually been shaped as cylindrical strip and grain-like granule. The particle size is generally 2mm*3mm. TPU granules are produced by underwater extrusion granulation. Why are most TPU plastic granular? Below detail analysis for your reference. 1. Easy to use and production The granules can mak...

How to prevent the agglomeration of soft TPU particles
Aug 19 , 2022
TPU particles agglomeration make the material feeding difficult and greatly influence the efficiency of injection production. TPU particles agglomeration is more easier happen in soft TPU particles in summer high room temperature environment. TO prevent the agglomeration of soft TPU particles, TPU manufacturer factory can take following measure when packing at the production. 1.Packing after granu...

Weak demand for TPU plastic in the market and TPU price keep going down
Aug 05 , 2022
From January 2022 to July 2022, the TPU price showed a trend of rising first and then reduce. This is due to the fact that the price of TPU raw materials has a great impact on the TPU price. After the new year, TPU price go up with the price of the raw material. But procurement of the TPU demand side obviously decrease. It is difficult to recover in the short term. In July, the price of TPU ended ...

Decoding tensile properties in the material data sheets of TPU
Jul 22 , 2022
Material data sheets showed material properties and can gain an in-depth understanding of the material during the material selection process. The same properties data will come out with different result by different test method , so it is important to test by the same standards when compare the properties of different material. TPU material tensile properties data is tested by ASTM standards. How ...

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...
