Product Description
PCTFE Stick:
PCTFE is the product of the trifluoroethylene radical-causing polymerization with a linear backbone of repetitive one CF (cl) -CF cells.PCTFE is a crystalline high molecule with a melting point of 425F and a density of 2.13g / cc (gram / cubic cm).PCTFE is inert to most lively chemicals at room temperature, while above 212T can be dissolved by a few solvents or swollen by some solvents, especially chlorinated solvents.PCTFE has the excellent ability to block gases, and the water vapor permeability of its membrane products is the lowest among all transparent plastic films.Its electrical properties are similar to other perfluoropolymers but the dielectric constant (2.3 – 2. knife and loss factors are slightly higher, especially at high frequencies.The PCTFE makes thick (1 / 8 inch) optical transparent pieces
Trifluorluorochloride or PCTFE, a polymer compound composed of trifluorochloride.Low molecular weight is a liquid or wax form.High molecular weight is a white solid or dispersion.Solid densities range from 2.1 to 2.2. Melting point ranged from 208 to 210℃.Heat, acid, alkali, and organic solvents (except halides), but not melting caustic alkali and elemental fluorine.Solsoluble in aromatic hydrocarbons and carbon tetrachloride.Chemical resistance is second only to PTFE.Can be used as an engineering plastic.Ttensile strength 3.096 to 4.135 Mpa (316 to 422 kg force / cm 2).Generally used in the high performance requirements of chemical equipment, insulation cables, radio devices, capacitances, and heat-resistant or low-temperature-resistant accessories.The dispersion solution is used to make corrosion-resistant coatings and thin films.
The PVC synthesis method includes bulk polymerization, solution polymerization and dispersion polymerization, and it is prepared with peroxide as the initiator by free radical polymerization.
PTFE has excellent chemical stability, insulation and weather resistance, and can be used in-196~125℃. The mechanical strength and hardness are better than PTFE, and the made film has good transparency and low permeability rate.
PTFE is suitable for application in contact with strong corrosion media, high pressure system sealing and cushion materials, observation window transparent materials, and electrical insulation materials, so it has special significance in chemical and atomic energy industries, but its price is more expensive than PTFE.Low molecular weight PTFE has high density, excellent viscosity-temperature characteristics and chemical corrosion resistance, and can be used as a high corrosive medium of sealing liquid, grease and balance liquid of navigation gyro.
PCTFE has excellent rigidity, low temperature resistance and cold flow resistance. It is an ideal sealing material under low temperature and high pressure conditions, and has special uses in the field of high-tech technology.
apply:
1. Contact with strong corrosion medium, sealing and cushion materials of high pressure system, transparent materials of observation window, etc.
2. Electrical insulation materials, etc.
3. Low molecular weight PCTFE is used as sealing liquid, grease and balance liquid of high corrosive medium.
