PFA, commonly known as fusible PTFE, has the highest performance among fluoroplastics and similar uses to FEP. It is widely used in semiconductor industry, medical treatment, chemical anti-corrosion, automobile and other fields.
The product forms of PFA include granular products for molding and extrusion, powder products for rotary molding and coating; Its semi-finished products include membranes, plates, rods, and pipes. The PFA resins distributed in the US market include DuPOut's Teflon brand, Daikin's Neoflon brand, Ansimont's Hshen brand, and HOechst Cellanese's Hostafl brand.
1. The main purpose of PFA is:
① Suitable for making corrosion-resistant parts, wear reducing and wear-resistant parts, sealing parts, insulation parts, and medical device parts.
② Insulation layer for high-temperature wires and cables, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
2. Forming performance
① Crystalline material with low moisture absorption. Products can be processed using the usual processing methods of thermoplastic.
② Poor fluidity and easy decomposition, producing corrosive gases during decomposition. It is advisable to strictly control the molding temperature not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the pouring system should have low resistance to material flow.
③ Semitransparent granular material, injection molding, extrusion molding. The molding temperature is 350-400 degrees, and above 475 degrees can easily cause discoloration or bubbles. And pay attention to the difficulty of demolding.
④ Due to the corrosive effect of molten materials on metals, long-term production requires chromium plating treatment for molds.

While more and more domestic fluorinated plastic products are going abroad, many well-known foreign fluorinated plastic processing enterprises have already or are preparing to settle in China. In the future, China is highly likely to become a production base for fluoroplastic products (especially low-end products) in the world. For domestic enterprises, the top priority is to adjust their business strategies in a timely manner, improve their own advantages, and establish a foothold in the market.
