PTFE(Poly tetra fluoroethylene,F4, Teflon) Generally referred to as "non-stick coating" or "easy to clean materials." This material is resistant to acids and bases and to various organic solvents and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used as a lubricant and it is also an ideal coating for easy cleaning of the inner layer of water pipes.
Kalshine offer high quality barrels and screws for the granulation of PTFE. Our screws are resistant to abrasion and corrosion. Suitable for long-term use.
We also offer specially sprayed single screws that are particularly suitable for applications with severe corrosion and wear.
