Europrene® N 3945 GRN是一种先进的冷聚合丙烯腈-丁二烯共聚物,在意大利的Portotorres生产厂生产。在生产过程中添加了一种不染色的抗氧化剂。Europrene® N 3945 GRN的特点是在高温下具有优异的加工性能和抗撕裂性,在压延和挤压过程中具有良好的尺寸稳定性。与标准牌号相比,GRN牌号具有更高的固化率、更高的低温柔韧性、更高的交联密度和更好的机械性能、更好的耐油性和耐燃油性。改进的可加工性保证了低污染的产品,然后长时间的生产运行,较低的模具磨损和较少的生产控制。中ACN含量为获得低温柔性和耐油性提供了一个很好的折衷方案。硫化可通过硫基体系或过氧化物进行。通过添加极性增塑剂作为己二酸、癸二酸或phtalic酸的合成酯,可以改善其低温性能。为了提高耐热性、耐光性和耐臭氧性,必须在合成过程中添加适当的保护剂,如胺或酚类抗氧剂。广泛的技术产品需要良好的加工性和很高的耐油和耐燃油性。适用于注射应用(低模具污染)。 Europrene® N 3945 GRN is an advanced technology cold polymerized acrylonitrile-butadiene copolymer made at the PortoTorres production facility in Italy. A non staining antioxidant is added during the production process. Europrene® N 3945 GRN is characterised by excellent processability and tear resistance at high temperature, good dimensional stability both in calendering and in extrusion. GRN grades show higher cure rate, higher low temperature flexibility, higher crosslinking density and better mechanical properties, better oil and fuel resistance in comparison to STD grades. The improved processability guarantees low mould fouling products and then long production runs, lower mould wear and less production controls. The medium ACN content gives a very good compromise to get both low temperature flexibility and oil resistance. The vulcanization can be performed by sulphur based systems or by peroxides. The low temperature properties can be improved by adding polar plasticizers as synthetic esters of adipic, sebacic or phtalic acids. To improve heat, light and ozone resistance, suitable protective agents as amine or phenolic antioxidants have to be added in the compounding process. Wide range of technical articles requiring good processability and a very high oil and fuel resistance. Suitable for injection applications (low mould fouling). |
