Get together ether aether ketone (Polyetheretherketone, PEEK) , linear scent a group of things with common features high polymer compound, by ether key, fragrant annulus, carbonyl is joined alternately and become, be a kind thermoplastic material of special type project.
The molecular catenary of the function PEEK of PEEK covers fragrant link, tigidity is very big, its have friend very advantageous high temperature resistant function, vitrification temperature is as high as 143 ℃ , melting point is as high as 343 ℃ , can work for a long time below the environment of 250 ℃ continuously, the environment of 300 ℃ leaves short-term job. PEEK quality of a material is solid, mechanical performance is superior, drawing model quantity can amount to 3.5GPa, did not enhance tensile strength to amount to 100MPa, flexural strength amounts to 165MPa, the change of environmental temperature is not big to the influence of PEEK mechanical function. After PEEK increases through Bo fine, mechanical function still can get bigger rise. Besides, PEEK still has the good denaturation that fight squirm can, and be able to bear or endure hand in change stress exhaustion function. The chemical performance of PEEK is steady, acting hydrocarbon of water, oily, bittern, common soda acid is not afraid of below normal temperature, dissolve Yu Nong is vitriolic. Ability falls in high temperature likelihood by haloid, strong acid, complex scent a group of things with common features compound is destroyed. PEEK is having good treatment liquidity, apply to note model, crowded piece, mould pressing, spray, can undertake fabricating. PEEK even if does not add fire retardant to also can reach V-0 level flame retardant the effect, the amount that send smoke is small, volatilize noxiousness is low. PEEK is had self-lubricating quality, suit to be used at requirement of low attrition work, also can use at having the environment that wear-resisting asks. PEEK insulation property is outstanding, be able to bear or endure it is good to await a gender, can use at cable to protect data. PEEK still has radiation resistance can, insulation property and mechanical property still can hold when γ irradiation dosage amounts to 1100Mrad. PEEK suits to undertake with of all kinds material compound increase, carbolic fine, Bo fine and mineral all can use. The development PEEK of PEEK is by company of company of industry of British empire chemistry (ICI) the project of freeboard function special type that developed 1978 is plastic, ever since Mitsui of Du Bang, BASF, Japan east press chemical company, VICTREX, United States Er spy general also develop similar product early or late. Among them the PEEK of ICI company already turned to be produced for VICTREX company. In, as a result of the performance with good PEEK, be regarded as strategical material of national defence war industry, to its research is included all the time 75 - 15 keys science and technology tackles key problem project and “863 plan ” . The Weigesi that main production studies to manufacturer has England company, inc. of high polymer material grinds in province of big Jilin of PEEK production company, still have Changchun in addition Jidate company of Tong Ruichi of capital of limited company north and Ji Daying achieve model high-powered polymer company. The field of applied PEEK application of THREE PEEK is extensive, common at car, war industry, medical treatment, aviation, electric wait for an industry. For example bone of car bearing, man-made, join is sold, gear.
