TPU is soft, has good tensile strength, impact strength and high and low temperature resistance, it is an ideal material for trachea and tubing. TPU pipes are mainly processed by extrusion. The processing temperature of TPU is in the range of 200-240. Because the material is relatively sticky, it tends to decompose during the production process to produce carbon residues. Similarly, the TPU in the screw is not completely exhausted when it is shut down, and more serious decomposition will occur during the cooling and overheating process.

SANP Tech. offers screw purging compound to improve efficiency in material switching, color switching, and carbon cleaning. At the same time, it is very suitable for sealing the screw when the machine is shutdown, which helps to avoid the generation of carbon residues.
