PVDF rod is made of PVDF resin through high temperature extrusion into the rod, is a quite pure polymer, it does not contain ultraviolet stabilizers, thermal stabilizers, softeners, lubricants or flame retardant and other additives. Oxygen content index is 46%, flame retardant, crystallinity of 65% -78%, density of 1.79~1.83g/cm3, melting point of 188℃, thermal deformation temperature of 120-151℃, long-term use temperature of-140-160℃. Due to the chemical inert of PVDF, it hardly reacts with any media. It is especially suitable for the transmission of pure chemical reagents in pure water systems and semiconductor industry.
Main characteristics of PVDF Plate and PVDF Rod: high temperature resistance (can continuously work at 150 degrees), excellent chemical corrosion resistance and hydrolysis resistance, outstanding UV resistance and climate resistance. High mechanical strength, good rigidity, good creep resistance, good slippage and wear resistance, inherent low flammability, good electrical insulation performance.
Disadvantages of PVDF sheet and PVDF rod : combustion containing fluorine smoke, not easy to stick.
Application field of PVDF Sheet and PVDF rod : due to the PVDF good chemical resistance, processing resistance, fatigue resistance and creep resistance, is the petrochemical equipment fluid treatment system as a whole or lining of the pump, valves,plastic pipes, plastic pipe fittings, storage tank and heat exchanger of one of the best materials. Its good chemical stability, electrical insulation performance, so that the production of equipment can meet the requirements of TOCS and flame retardant, is widely used in the storage and transportation of high purity chemicals in the semiconductor industry, semiconductor, liquid crystal associated devices and other electronic industry, chemical equipment, food processing machines, etc.
The CPVC sheet and CPVC rad products are dark gray or light gray, tasteless, odorless, nontoxic, loose particles or powder. After chlorination of PVC resin, the irregularities and polarity of molecular bonds increase, increasing the solubility and chemical stability of the resin, thus improving the corrosion of heat resistance, acid resistance, alkali, salt and oxidant of the material. The CPVC plate and the CPVC rod improve the mechanical properties of the numerical thermal deformation temperature, increasing the chlorine content from 61.7% to 72-75%, and the Vica softening temperature from 60-72℃, (increased to 85-96℃), with the maximum use temperature of 112℃, and the long-term use temperature of 90℃. Therefore, the CPVC sheet and the CPVC rod are new engineering plastics with promising applications.
CPVC sheet and CPVC rod corrosion resistance: the most suitable for corrosion protection equipment. Easy processing, cutting, welding, bending are very easy. High strength, high stiffness and high hardness; good electrical insulation; good chemical stability; self-extinguishing; low water absorption; easy bonding and easy to paint.
The irregularity and polarity of Plastic Sheet and PVC Rod increase the solubility of the resin and the chemical stability, thus improving the heat resistance, acid resistance, alkali, salt, oxidant and other corrosion, and improving the mechanical properties of the numerical thermal deformation temperature. Compared with the general PVC Sheet, it has better high temperature resistance, excellent corrosion resistance, stable size, easy processing, excellent flame retardant and other characteristics.
