Why TPU Elastomer is an environmentally friendly plastic material
May 20 , 2022
Thermoplastic polyurethane TPU Elastomer is a non-toxic and odorless material. Some TPU series have passed medical certification and FDA certification, and can be implanted into the human body and contact with food. TPU plastic is recyclable and can be used in many industries. TPU resin can decompose after a certain period of time, and will not cause pollution to the environment. TPU does not cont...

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...

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...

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....

What is shrinkage of plastics?
Mar 01 , 2023
The shrinkage of plastics is the volume contraction ratio of polymers from melt state to the cooled and rigid state. Most of the shrinkage occurs in the mold while cooling. A small amount of shrinkage occurs after injection as the molded part continues to cool. Total shrinkage is a result of molding shrinkage and post-shrinkage. The shrinkage of TPU plastic resin is ranged from 0.1% to 1%. The shr...
