PTFE corrugated hose has been widely used in various corrosion-resistant mechanical seals. The manufacture of the bellows is divided into two steps: first, the blank tube is manufactured and then turned. The PTFE blank tube material consists of three sections, the middle section is pure PTFE, and the two ends are filled PTFE. 1. Raw … Read More
PTFE is an extremely widely used engineering plastic. It has excellent properties such as excellent resistance to media, low coefficient of friction, and a wide operating temperature range. It plays an important role in sealing and lubricating fields. Due to the high melting temperature and melt viscosity of PTFE, it is not easy to process, … Read More
PTFE color film is suitable for the insulation of electrical instruments or wires that are distinguished by color. It is a new type of C-class insulating material with excellent comprehensive performance. It is one of the indispensable and important materials in the radio industry, aviation industry, and cutting-edge science and technology. PTFE film generally uses … Read More
Ordinary PTFE pipes will rupture when subjected to a pressure of about 40kg/cm2. When they are combined with steel wires, their pressure resistance is greatly improved. The maximum working pressure abroad reaches 700kg/cm2. Studies have shown that the compressive strength and impulse strength of the hose is not only related to the strength of the … Read More
PTFE heat shrinkable tube has the characteristics of shrinkage, so it can be tightly wrapped on the surface of other workpieces so that the workpiece has corrosion resistance, electrical insulation, and anti-sticking properties. It is widely used in electrical, chemical, machinery, printing, and other industries. It is reported that the maximum shrinkage rate of PTFE … Read More
PTFE sheets can be divided into three categories: SFB-1 is mainly used for electrical insulation, SFB-2 is used for corrosive medium gaskets, dense linings, and lubricating materials, and SFB-3 is used for diaphragms in the corrosive medium. According to the different molding processes, it can be divided into two types: molded plate and rotary cutting … Read More
Suspension Polymerization Method Applications Suspension Polymerization is mainly used to manufacture seals, gaskets, etc. used in the machinery industry, as well as pumps, valves, pipe fittings, and equipment linings used in chemical equipment, as well as electrical insulation parts and films. Suspension Polymerization raw materials are generally divided into the following three categories: Fine powder: … Read More
Although PTFE plastic has many advantages, its production method is different from other plastics. PTFE plastic molded products use PTFE suspension resin in a steel mold, pressed into a blank on a press, and then sintered. The forming process of PTFE fluoroethylene plastic is divided into the following six steps 1. Drying In the process … Read More
The components of the modified PTFE products are determined according to the application environment of the filled products. There are single filler filling and several kinds of filler compound filling. For example, 20% SiO2 filled PTFE is used as a piston ring of oxygen compressor, 10% polyamide, 15% glass fiber, 5% graphite compound filled PTFE … Read More
Filled PTFE products generally adopt the compression molding process: the quality of modified PTFE products mainly depends on the choice of resin filler, the design of the formula, the uniformity of material mixing, and other factors. There are three mixing methods used to fill PTFE: (1) The dry mixing process requires the mixing device to … Read More
