PEEK Series

Polyetheretherketone (PEEK) resin is a special engineering plastic with excellent performance, compared with other special engineering plastics has more significant advantages. My company production of PEEK products can reach the maximum size of diameter 1500MM, currently the most mature technology. 1, mechanical properties PEEK is both toughness and rigidity and balance of plastic, alloy material with comparable. 2, the self lubrication sliding characteristics: PEEK has superior in all plastics. 3, chemical resistance (corrosion resistance): PEEK has excellent chemical resistance. Its corrosion resistance and similar nickel steel. 4, fatigue resistance: PEEK has the best fatigue resistance in all resin. 5, hydrolysis resistance: PEEK and its composite materials from chemical effects of water and high pressure steam, products made with this material in high temperature and high pressure water continuous use can still maintain excellent performance. 6, high temperature resistant PEEK resin has high melting point (334 C) and the glass transition temperature (143 DEG C), continuous use temperature of 260 DEG C. 7, the stability: PEEK products with superior dimensional stability characteristics, it is very important for some applications and some. Changes in temperature, humidity and other environmental conditions on the PEEK part size has little effect, can meet the precision requirement with relatively high condition requirements. PEEK is mainly used in high temperature and high pressure and contact corrosion and other harsh conditions, but also used in sanitary products.

PCTFE Series

Poly three vinyl fluoride PCTFE, polymer compound composed of three fluoride vinyl chloride through polymerization. Solid density 2.1~2.2. The melting point of 208~210 deg.. Heat resistance, acid and alkali resistance, but not (except halide) resistant to molten caustic and elemental fluorine. After the chemical resistance of ptfe. The tensile strength of 3.096~4.135 MPa (316~422 kg / cm 2). Generally used in high performance chemical equipment, insulation cable, radio device, and capacitor with heat resistant or low temperature resistant parts etc.. Poly three vinyl chloride fluoride has excellent chemical stability, insulation resistance and weatherability, in 196 to 125 DEG C for long-term use, mechanical strength and hardness than that of ptfe. Poly three vinyl chloride fluoride is suitable for use in sealing contact with strong corrosive medium, high pressure system, so in the chemical industry, atomic energy industry has special significance, but its price is expensive than teflon. PCTFE has excellent rigidity, low temperature resistance, resistance to cold flow performance, is an ideal sealing material of low temperature and high pressure conditions, has a special use in the field of high technology. The application of PCTFE in the valve seal, mainly used in pressure contact with strong corrosive medium, and low temperature sealing etc.. Numerical PCTFE product project unit: density g/cm32.10-2.18, tensile strength of Mpa is higher than 30, the elongation% is more than 20, the continuous use of the highest temperature -200-100 degrees
