Detailed Description

PEEK is a crystalline thermoplastic aromatic polymer material, the melting point of 334 degrees Celsius, with high mechanical strength, high temperature, impact resistance, flame retardant, acid hydrolysis, abrasion resistance, fatigue resistance, radiation and good electrical properties. High temperature PEEK resin has a high melting point (334 degrees C) and glass transition temperature (143 degrees Celsius), continuous use temperature of 260 degrees Celsius, and its 30% GF or CF reinforced grades Temperature of the load up to 316 degrees Celsius. Degrees Celsius. Mechanical properties of polyether ether ketone resin has good toughness and rigidity. It has alloy materials with comparable quality to the alternating stress fatigue resistance. Self-lubricating (corrosion resistance) polyether ether ketone resin has excellent sliding properties, suitable for low coefficient of friction and resistance to abrasion demanding circumstances. Its chemical resistance and corrosion resistance of nickel steel similar. PEEK dissolved in concentrated sulfuric acid only, good chemical resistance, especially in high temperature conditions more acid than the polyimide. Flame of PEEK polymer resin is very stable, 1.45mm thick sample, without any flame retardant can achieve the highest standards. Radiation resistance and resistance to stripping of PEEK has good radiation resistance and resistance to stripping, it can be used to make special-purpose wire. Fatigue resistance of PEEK resin in all resin has the best resistance to fatigue. Hydrolysis of PEEK resin and products made of composite materials in high temperature and pressure water can still be used continuously to maintain its good performance. Easy processing of PEEK resin at high temperatures with good mobility, high thermal decomposition temperature, can be used injection molding, compression molding, extrusion molding, blow molding, melt spinning and other processing methods. Stability of PEEK insulation has good electrical insulation properties, and maintain the high temperature range. The dielectric loss at high frequencies is small. Abrasion wear resistance of PEEK is equivalent to a good polyimide.
