If the Shrinkage Rate of TPU Film Change Following Different Hardness ?
The shrinkage rate of plastic film refers to the volume shrinkage of plastic film during processing. The shrinkage rate of TPU polyurethane film is affected by many factors such as raw material quality, strength, the thickness, heat treatment process and the colling rate , etc. If the shrinkage rate of TPU film change following different hardness?
TPU film is lower shrinkage rate following higher hardness.
High hardness TPU film and TPU elastomer with tighter and more stable molecular structures, which are not easy to deform at high temperature. Therefore, lower shrinkage during processing and cooling.
The shrinkage rate is a very important performance parameter in the plastic film production process, which is directly related to the heat resistance and geometric accuracy of the plastic finished product.
POLYSAN company is professional in producing and supplying low shrinkage TPU film, PVC film, PET film and EVA film to ensure the high quality of the plastic products after processing.
