Forming principle of TPU film

Date:Jul 19, 2019

TPU film forming principle: the chemical and thermal properties of TPU pellets with high levels of physical processing and cross-linked TPU elastomers.

The TPU film is a TPU pellet melt-plasticized by an extruder, extruded from a machine head through a slit die, so that the melt adheres to the cooling roller, and then is peeled, stretched, slit, and wound. To the finished product. Its thickness and width, hardness and surface finish can be customized according to customer needs.

The thickness of the TPU film is controlled by the rotation speed of the wheel and the screw; the surface effect of the TPU film is controlled by the wheel temperature.

The control method is as follows:

1. Adjust the wheel when the screw speed is fixed;

2. Adjust the screw when the rotation speed of the wheel is fixed.
