PEEK screw, peek screw nut, peek
Peek is aromatic crystalline thermoplastic polymer material, its melting point is 334 ℃, with high mechanical strength, high temperature resistant, impact resistant, flame retardant, acid and alkali resistance, hydrolysis resistance,wear resistance, fatigue resistance, radiation resistance and good electrical properties.
● high temperature resistant polyetheretherketone resin has higher melting point (334 ℃) and the glass transition temperature (143 ℃), continuous use temperature is 260 ℃, the 30%GF or CF enhanced grade load thermal deformation temperature up to 316 ℃.
℃.
The mechanical properties of polyether ether ketone resin has goodtoughness and rigidity. It has excellent fatigue resistance of alternating stresscomparable with the alloy material.
● self lubrication (corrosion resistance) of PEEK resin has excellent slidingcharacteristics, suitable for low coefficient of friction and abrasion require strictconditions.
● chemical resistance and its corrosion resistance and nickel steel similar.Peek can only be dissolved in concentrated sulfuric acid, good chemical resistance, especially under the condition of high temperature resistantpolyimide more than.
● flame retardant polyether ether ketone resin is very stable polymer, 1.45MM thick samples, without any flame retardant can reach the highest flame retardant standards.
The radiation resistance and peeling resistance peek has good radiation resistance and peeling resistance, electromagnetic line so it can be used tomake special use.
The fatigue resistance of polyether ether ketone resin has better fatigue resistance in all the resin.
● hydrolysis products made of polyether ether ketone resin and its composite material can maintain its good performance of continuous use under high temperature and high pressure water.
● easy machining of PEEK resin has good fluidity at high temperature, has thevery high thermal decomposition temperature, can be used in injection molding, compression molding, extrusion, blow molding, melt spinningprocessing.
● insulation stability peek has good electrical insulating properties, and keep the temperature is very high. The dielectric loss at high frequencies is very small.
Good wear resistance, abrasion resistance peek equivalent of polyimide.
Peek is a kind of special engineering plastics. Can match with polyimide, called super heat-resistant thermoplastic resin. Characteristic has the very attractive;
(1) the short-term resistance: glass fiber or carbon fiber reinforced the thermaldeformation temperature can reach 300 ℃.
(2) long-term heat resistance: UL temperature index (RTI) is 250 ℃.
(3) toughness: is a very flexible resin.
(4) flame retardant: reach UL94V level 0 (1.5mm), a Zixi, burning smoke amount is all the resin in the least.
(5) the corrosion resistance / resistance: in addition to sulfuric acid solvent free to the erosion of its.
(6) hot water resistance (can be used in 200 ~ 300 ℃ steam).
(7) the fatigue and creep resistance is the highest (thermoplastic plastics;
(8): in the process of injection molding, and is also suitable for various molding methods
Because it has a high temperature (350 ～ 400 ℃) good fluidity and thermal decomposition temperature is very high (560 ℃) characteristics, so it can beused for injection molding, extrusion molding, molding, blow molding, melt spinning, rotational molding, powder spraying methods such as molding. As the two processing can use vacuum forming, rolling, drawing, ultrasonic welding, adhesive, composite, mechanical processing and other processingmethods.
