PEEK特點
耐輻照性、絕緣性穩(wěn)定、耐水解,抗壓,耐腐蝕,其符合材料制作成的機(jī)械零件具有自潤滑效果。
.耐溫、熱穩(wěn)定性佳、超高耐熱(較PPS優(yōu)良)、HDT在315攝氏度以上,UL連續(xù)使用溫度為250攝氏度。
1:機(jī)械特性PEEK是韌性和剛性兼?zhèn)洳⑷〉闷胶獾乃芰稀L貏e是它對交變應(yīng)力的優(yōu)良耐疲勞是所有塑料中出眾的,可與合金材料媲美。
2:自潤滑性PEEK在所有塑料中具有出眾的滑動特性,適合于嚴(yán)格要求低摩擦系數(shù)和耐摩耗用途使用。特別是碳纖、石墨各占一定比例混合改性的PEEK自潤滑性能更佳。
3:耐化學(xué)藥品性(耐腐蝕性)PEEK具有優(yōu)異的耐化學(xué)藥品性.在通常的化學(xué)藥品中,能溶解或者破壞它的只有濃,它的耐腐蝕性與鎳鋼相近。
4:阻燃性PEEK是非常穩(wěn)定的聚合物,1.45mm厚的樣品,不加任何阻燃劑就可達(dá)到高阻燃標(biāo)準(zhǔn)。
5:耐剝離性PEEK的耐剝離性很好,因此可制成包覆很薄的 或電磁線,并可在苛刻條件下使用。
6:耐疲勞性PEEK在所有樹脂中具有好的耐疲勞性。
7:耐輻照性耐高輻照的能力很強(qiáng),超過了通用樹脂中耐輻照性好的聚乙烯。可以作成γ輻照劑量達(dá)1100Mrad時仍能保持良好的絕緣能力的高性能 。
8:耐水解性PEEK及其復(fù)合材料不受水和高壓水蒸氣的化學(xué)影響,用這種材料作成的制品在高溫高壓水中連續(xù)使用仍可保持優(yōu)異特性。
Characteristics of PEEK
Stable irradiation resistance, insulation, hydrolysis resistance, compressive strength, corrosion resistance, the composite material made of mechanical parts have self lubricating effect.
. Heat resistance, good thermal stability, and high heat resistant (PPS) fine, HDT above 315 degrees Celsius, UL continuous use temperature is 250 degrees Celsius.
1: the mechanical properties of PEEK is tenacity and rigidity of both plastic and balance. Especially its excellent resistance to fatigue of alternating stress is the most outstanding in all the plastic, can be comparable to alloy material.
2: self lubrication PEEK has superior in all plastic sliding characteristics, suitable for strict with low coefficient of friction and abrasion consumption purposes. Especially the carbon fiber, graphite, a certain percentage of each hybrid modified PEEK self-lubricating performance is better.
3: chemical resistance, corrosion resistance) PEEK has excellent chemical resistance. In the usual chemical, can dissolve or destroy it only concentrated sulfuric acid, its corrosion resistance and nickel steel.
4: flame retardant PEEK is very stable polymer, the sample of the 1.45 mm thick, without any flame retardants can achieve the highest standard of flame retardant.
5: stripping resistance PEEK stripping resistance is very good, because this can make the cladding or electromagnetic wire is very thin, and can be used in harsh conditions.
6: fatigue resistance PEEK in all resin has the best fatigue resistance.
7: irradiation resistance high irradiation resistant ability is very strong, more than the general irradiation resistance best polystyrene resin. Can be made into the radiation dose of 1100 mrad can still keep good insulating ability of high performance.
8: hydrolysis resistance PEEK and its composites is not affected by the chemistry of water and high pressure steam, with products made of this material in high temperature and high pressure water continuous use can still maintain excellent properties.
