The PTFE board can be permanently modified by using acrylic monomer. The characteristics are generally tried and completed. Through the experiment, the optimization premise of the plasma pretreatment is confirmed, so as to know the root of the hydrophilicity improvement of the PTFE film. 

The polyethylene floating body is produced by advanced rotomolding process, fully formed in one time, corrosion-resistant, anti-aging, anti-impact collision, no leakage cracking, internal closed foam, large buoyancy, even if the shell is damaged, it will not affect the use. The polyethylene floating body is mainly used for rivers and lakes, and the buoyancy support of the pipeline on the ocean. High bearing capacity, light weight, strong wear resistance, easy to install and transport, low transportation transfer cost, simplified and durable. The buoyancy section per square meter is more than 350kg.

The PTFE sheet has the advantage of the most significant voltage resistance and breakdown voltage. Used in capacitor media, as wire insulation, electrical instrument insulation, sealing gasket.

A directional film formed by rolling a PTFE film by a calender with a calender. The crystallinity is high, the molecular orientation is tightly arranged, and the void ratio is small, so that the PTFE film is greatly improved, especially The voltage resistance is more pronounced.
