What factors affect the chemical resistance of PEEK rods: Important influencing factors include: continuous working temperature, mechanical load, climate influence, fire performance requirements and electrical conductivity.
The PEEK filament is extruded with imported extrusion equipment, and the raw material of the product is imported pure resin from Vigers PEEK450G. PEEK filaments have a normal working temperature of 260 degrees and have corrosion resistance. They can be used in solvents for a long time. Because PEEK filaments are resistant to hydrolysis, they can be cleaned and disinfected in high-temperature steam. PEEK filament is an environmentally friendly material, in line with the US FDA food sanitation requirements, and itself is flame-retardant, and has a wide range of applications.
PPSU is a slightly amber linear polymer. In addition to strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to general acids, alkalis, salts, alcohols, and aliphatic hydrocarbons. Partly soluble in ester ketones and aromatic hydrocarbons, soluble in halocarbons and DM. Good rigidity and toughness, temperature resistance, heat oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acids, alkalis, salt solutions, ion radiation resistance, non-toxic, good insulation and self-extinguishing, easy to mold and process.
PSU has a wide range of applications. In the field of electronics and electricity, PSU can be used to make various electrical parts such as contactors, connectors, transformer insulators, thyristor caps, insulating sleeves, coil bobbins, terminals and slip rings, and printing Circuit boards, bushings, covers, TV system parts, capacitor films, brush holders[1], alkaline battery boxes, etc.; in the automotive and aerospace fields, PSU can be used to make protective cover components, electric gears, battery covers, detonators, Electronic ignition device components, lighting components, aircraft interior parts and aircraft exterior parts, outer protective covers of aerospace vehicles, etc. It can also be used for PSU to make luminaire baffles, electric transmissions, sensors, etc. The demand for polysulfone polymers used to make cabin parts in the world market continues to grow.
PEI (Chinese name polyetherimide) is a thermoplastic engineering resin with an amber transparent solid appearance. It has excellent heat resistance, high strength and rigidity, as well as a wide range of chemical resistance, which can meet higher heat. Chemical and elastic demand. Its unique torsional strength among thermoplastics makes it an inexpensive alternative to small steel cutting parts. As an amorphous thermoplastic polyetherimide, PEI resin combines high performance and excellent processing characteristics, combining high heat resistance with high strength, modulus and extensive chemical resistance.
Anti-static PEEK board performance characteristics: under the conditions of high strength and rigidity, electrostatic conductivity, excellent dimensional stability, continuous working temperature up to 250 °C, non-flammable (UL 94 V0), filled with carbon fiber, graphite and PTFE, low Friction coefficient, wear resistance and self-lubrication, anti-static grade, resistivity 10^6-10^9 Ωcm, better prevent static charge accumulation.
