Board price -PEI board price PEEK and PI Overview and characteristics of the advantages and disadvantages of a material, the material overview PEEK and PI, respectively synthesized by Victrex Corporation and DuPont patents and has high-performance materials, PEEK and PI in High performance polymers have other common plastic unmatched very excellent performance, for a variety of harsh environments with a high performance, has been successfully applied in a wide range of aerospace, automotive, electronics semiconductors, electrical and other industries in the more stringent requirements of the occasion . The users new product development, improving the preferred material product life and reliability. Second, the characteristics of high temperature advantages ◆ UL certification for long-term use temperature of 260 ℃. Even when the high temperature reached 300 ℃, can still maintain excellent mechanical properties and wear resistance ◆ In many high-temperature, high load, corrosion and other extremely harsh environments, PEEK polymer and composite materials have excellent resistance wear performance. ◆ has a self-lubricating low friction coefficient, can be realized without oil lubrication, can work in the oil, water, steam, weak acid and other media term. ◆ corrosion is not soluble in common solvents, a variety of organic and inorganic chemicals, have good corrosion resistance. ◆ High strength with the best mechanical strength in plastics. It also has high rigidity and surface hardness. ◆ easy processing using the injection molding process can be directly processed parts. Can be processed for turning, milling, drilling, tapping, ultrasonic bonding and welding. ◆ hydrolysis at temperatures in excess of 250 ℃ in high-pressure steam or water immersion, PEEK products still can work for thousands of hours without significant performance degradation. ◆ flame retardancy without using any additive, the thickness of the PEEK samples 1.45㎜ flammability rating of UL94 V-0 levels. ◆ When low smoke and toxic fumes and toxic gas volume is particularly low. ◆ electrical properties over a wide temperature and frequency range, can still maintain a stable, excellent electrical properties. ◆ radiation resistance is extremely resistant to high doses of γ-ray radiation, mechanical performance can be retained intact, the device can be used as nuclear radiation-resistant parts. ◆ dimensional stability Disadvantages ■ injection process demanding, high machining process requirements. ■ relative to the metal material strength somewhat lower. PEEK- because application of the product and have a number of different composite materials, there is a 30% glass fiber containing 30% of carbon fiber containing 30% (carbon fiber + graphite + PTFE) Melting point: 340 ℃ heat distortion temperature: 315 ℃ continuous use temperature : 260 ℃ Electronic Materials Co., Ltd., Dongguan Han Lin ||| board price -PEI board price
