现货交易医疗级pc 2458(科思创)高粘度 环氧乙烷消毒 生物兼容性 出模性能良好product description: polycarbonate (pc)colorless transparent, heat-resistant, impact-resistant,flame-retardant bi-grade, in the ordinary use of temperature havegood mechanical properties. polycarbonate has good impactresistance, high refractive index, good processability, and ul94v-0 flame retardancy without any additives, compared withpoly-lrb-methyl methacrylate) . but poly(methyl methacrylate) arecheaper than polycarbonate and can be used in bulk polymerizationto produce large devices. pc bayer 3108 germany main advantages 1.with high strength and elastic coefficient, high impact strength,wide application temperature range; 2. high transparency and freedyeing; 3. low shrinkage and good dimensional stability; 4. goodfatigue resistance 5. good weather resistance 6. excellentelectrical characteristics. pc german bayer 3108 key performance1.0. mechanical properties: high strength, fatigue resistance,dimensional stability, creep is small (also very little change athigh temperature) ; 2. the temperature index of ul reached 120 ~140 ° c (outdoor long-term aging was also good) . 3. solventresistance: no stress cracking; 4. on water stability: hightemperature water easy to decompose (high temperature and highhumidity environment use caution) ; 5. electrical performance: 6.insulation: excellent (moisture, high temperature can also maintainelectrical stability, is the manufacture of electronic andelectrical parts of the ideal material) ; 7. dielectriccoefficients: 3.0-3.2; 8. arc resistance: 120s; 9. moldingprocessability: common e for injection molding orextrusion.

 

医用级pc的典型特性是韧性、强度、刚性和耐热蒸汽消毒比较好，这些特点使得pc优先选择成为血液渗析过滤器、外科工具柄和氧气罐（当在外科心脏手术中，这种仪器可以去除血液中的二氧化碳，增加氧气）；pc在医学上的应用还包括无针注射体系、灌注仪器、血液离心机碗和活塞。利用其高透明性能，通常的近视眼镜是pc做成的。
