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 have good mechanical properties. Polycarbonate has good impact resistance, high refractive index, good processability, and UL94 V-0 flame retardancy without any additives, compared with poly-LRB-methyl methacrylate) . But Poly(methyl methacrylate) are cheaper than polycarbonate and can be used in bulk polymerization to 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 free dyeing; 3. Low shrinkage and good dimensional stability; 4. Good Fatigue Resistance 5. Good Weather Resistance 6. Excellent electrical characteristics. PC German Bayer 3108 key performance 1.0. Mechanical properties: high strength, fatigue resistance, dimensional stability, creep is small (also very little change at high temperature) ; 2. The Temperature Index of UL reached 120 ~ 140 ° C (outdoor long-term aging was also good) . 3. Solvent Resistance: no stress cracking; 4. On water stability: high temperature water easy to decompose (high temperature and high humidity environment use caution) ; 5. Electrical Performance: 6. Insulation: excellent (moisture, high temperature can also maintain electrical stability, is the manufacture of electronic and electrical parts of the ideal material) ; 7. Dielectric coefficients: 3.0-3.2; 8. ARC resistance: 120s; 9. Molding processability: common equipment for injection molding or extrusion.
