Application of polytrifluoroethylene in greases
Polytrifluoroethylene based grease (PCTFE) is made from polytrifluoroethylene (PCTFE) as a base oil with special additives such as heat and corrosion resistance. Polytrifluoroethylene (PTFE) is a silicone-based thick grease suitable for strong oxidation and other corrosive chemicals.
Product characteristics of polyvinyl chloride trifluoride:
1. Excellent extreme pressure and wear resistance, scratch resistance, low vapour pressure, slow evaporation, suitable for long-term lubrication in high vacuum systems.
2. Thermal stability, oxidation resistance, NO generation, colloidal carbon.
3. Non-combustible (will not burn even in liquid oxygen or gas), radiation resistant (radiation dose 107 rad), low evaporation.
4. Resistant to organic solvents, acids and bases and other strong corrosive media.
5. Impact water resistant, chemically inert, good compatibility with plastics, rubber and other non-metallic materials and metals.
Chemical industry electronics/semiconductor industry; oxygen industry; automotive industry. Fluid sealing machinery, oxygen valves, inert packing, non-combustible hydraulic presses, petroleum oxygen pumps and compressors. Oxygen lubricants, lubricants for diving equipment, piston oils, glass joints. Inert lubricants for paper making. Inert vacuum extractors, chemical vapour deposition equipment, etc. for service in hard vacuum plasma etching. Proton-free, non-flammable lubricants and hydraulic fluids for use in the nuclear industry. For valves, seals, gears, liquids or gases, oxygen, chlorine, 90% nitric acid, red fumes, other oxides or corrosive chemicals. Silicone based greases are susceptible to hydrogen fluoride or other fluorides and can be used as laboratory piston greases in these cases.
A detailed analysis of the current situation, market competition and the supply and demand situation of the polyvinyl chloride (PVC) industry in China. The opportunities and challenges facing the industry are analysed in terms of the policy environment, the economic environment, the social environment and the technological environment. In addition, the paper analyses the current situation and development mode of enterprises and makes professional forecasts on the development trend in the coming years. It provides career guidance and advice for enterprises, research institutions and investment institutions to understand the new development trends and competitive landscape of the industry and to grasp the future development trends from this industry.
Polyvinyl Chloride Trifluoride (PCTFE) is a homopolymer of trifluoroethylene with fluorine and chlorine atoms in its main carbon chain. The general formula of the chemical structure
The atoms in the molecular structure make the polymer chemically inert and the CI atoms give the polymer its transparency, thermoplasticity and toughness, making PCIFE highly stable, heat resistant and non-flammable. A non-hygroscopic, impermeable, inert, high-quality thermoplastic resin. Due to the presence of C-CI bonds in the molecular structure of PCTFE, its hardness, toughness, creep resistance, low permeability, low melting point and low melt viscosity, with the exception of thermal resistance and chemical inertness. Polytetrafluoroethylene (PTFE) and tetrafluoroethylene-hexafluoropropylene (FEP) copolymers are slightly less performant.
