The grades of TPU particles (resin) can be simply categorized into: injection grade, extrusion grade, and blowing grade. Some TPU material is molded by particles and some are made of varying thicknesses films for different product applications. TPU can be recycled, coloring, and has high processing efficiency.
TPU has been widely used in electronic appliances, the health care industry and footwear, because of easy processing, which it is suitable for extrusion molding and injection molding machines. However, TPU easily absorbs water, if moisture control is not thorough during processing, it will result in poor performance. So drying process is required before manufacturing.
