Special sales Qingdao imported character defibrillators PEEK plate PEEK-GF black plate Guangzhou, Qingdao special sales PEEK material wholesalers import character defibrillators PEEK PEEK-GF plate black plate PEEK material wholesalers, special sales, Guangzhou, Qingdao imported character defibrillators PEEK sheet black PEEK- GF plate PEEK material wholesalers Guangzhou English name Polyetheretherketone; Chinese: PEEK; when the temperature reaches 260 degrees before the material has excellent dielectric properties. And resistance to energy ray irradiation. PEEK is a 4,4-difluoro-benzophenone and hydroquinone in the presence of an alkali metal carbonate, diphenyl sulfone as a solvent in the condensation reaction of a new type of semi-crystalline engineering thermoplastic aromatic plastic. PEEK case of high temperature thermoplastic plate which has a high glass transition temperature (262 ℃) and melting point (358 ℃), heat distortion temperature up to the load 332 ℃ (30% glass fiber or carbon fiber reinforced grades), in 260 ℃ Long-term use, such as PI, PPS, PTFE, PAI, PPO, etc. compared with other high temperature plastic, an upper temperature limit was nearly 60 ℃; PEEK resin is not only excellent in heat resistance than other high-temperature plastic, and has high strength, high modulus, high fracture toughness and good dimensional stability; PEEK resin at high temperature can maintain high strength, its bending strength at 200 ℃ up to about 24MPa, PEEK plate at 260 ℃ bending strength and compressive strength is still 15 ~ 19MPa; PEEK resin of greater rigidity, good dimensional stability, low coefficient of linear expansion, very close to the aluminum material; has excellent chemical resistance, in the usual chemicals, only concentrated sulfuric acid to dissolve or destroy it, its corrosion resistance and nickel steel similar, while its own flame retardant, release less smoke and toxic gases under fire conditions, anti-radiation and strong; PEEK plate resin toughness, good for alternating stress fatigue resistance is the most outstanding of all plastics, can be comparable with alloys; PEEK resin has outstanding tribological properties, resistance to sliding wear and fretting excellent wear properties, PEEK plate especially to maintain high wear resistance at 256 ℃ and a low friction coefficient; PEEK resin easy extrusion and injection molding, excellent processability, high molding efficiency. In addition, PEEK also has a self-lubricating, easy processing, insulation and stability, hydrolysis, excellent performance, PEEK plate has excellent overall performance, good mechanical properties, high temperature resistance, excellent chemical resistance, making it the most common high-grade plastic. Main features: 1: Long-term use of high temperature UL certification temperature 260 ℃. Even when the high temperature reached 300 ℃, can still maintain excellent mechanical properties 2: wear resistance in many high temperature, high load, corrosion and other extremely harsh environments, PEEK polymers and composites have excellent wear resistance. 3: Self-lubricating with a low coefficient of friction, lubrication can be achieved without work, available to work in the oil, water, steam, weak acid and other medium and long-term. 4: Corrosion is not soluble in common solvents, a variety of organic and inorganic chemicals, have good corrosion resistance. 5: High intensity has the best mechanical strength in plastics. It also has high rigidity and surface hardness. 6: easy processing using injection molding process can be directly processed parts. Can be processed for turning, milling, drilling, tapping, ultrasonic bonding and welding. 7: water solution at temperatures above 250 ℃ in the high-pressure steam or water immersion, PEEK products still can work continuously for thousands of hours without significant performance degradation. 8: flame retardancy without using any additive, the thickness of the PEEK samples 1.45㎜ flammability rating of UL94 V-0 levels. 9: low smoke and toxic fumes and toxic gas volume is particularly low. 10: electrical properties over a wide temperature and frequency range, can still maintain a stable, excellent electrical properties. 11: radiation resistance is extremely high doses of anti-γ-ray radiation, mechanical performance can complete reservations, can be used in radiation-resistant nuclear equipment parts. 12: dimensionally stable 13: peeling resistance PEEK has excellent peeling resistance, and therefore can be made of or coated with a thin wire, and can be used in harsh conditions. 14: chemical resistance (corrosion) PEEK has excellent chemical resistance in ordinary chemicals can dissolve or destroy it only concentrated its corrosion resistance and nickel steel similar.
