Polytetrafluoroethylene board can make acrylic monomer achieve long-lasting hydrophilicity. These characteristics are generally accomplished through experiments. Through experiments, the optimal premise of plasma pretreatment can be determined, so as to understand the origin of the increased hydrophilicity of PTFE membrane.

The PTFE floating body is produced by advanced rotational molding technology. Fully-enclosed one-piece molding, corrosion resistance, aging resistance, impact resistance, no water leakage, no cracking, internal fully enclosed foam, high buoyancy. Even if the shell is damaged, it will not affect the use. Polyethylene floating bodies are mainly used for the buoyancy support of rivers, lakes, and ocean transportation pipelines. High load-bearing capacity, light weight, strong wear resistance, convenient installation and handling, low transportation and transportation cost, stable and durable cylinder, buoyancy of more than 350kg per square meter.

Polytetrafluoroethylene board has the advantages of significant voltage strength and breakdown voltage. Used as capacitor dielectric, wire insulation, electrical instrument insulation and sealing gaskets. The oriented film made of turning PTFE film by hot rolling. The crystallinity is high, the molecular orientation is tightly arranged, and the porosity is low. Therefore, the PTFE film has been greatly improved, especially the withstand voltage strength is more obvious.
