牌号简介	液体硅橡胶（LSR）医疗器械和组件制造的原材料，在医疗保健行业应用Silastic® Q7-7840液体硅橡胶、硅橡胶Q7-7850液体硅橡胶和硅橡胶Q7-7870液体硅橡胶，零件A和B是热固化弹性体，供制造医疗器械的客户使用，包括那些计划植入人体少于30天和非植入应用。Silastic® Q7-7840液体硅橡胶、硅橡胶Q7-7850液体硅橡胶和硅橡胶Q7-7870液体硅橡胶是专为液体注射成型或支撑挤压设计的两部分铂催化硅橡胶。弹性体作为一个由两部分组成的套件（A部分和B部分）提供，在使用前必须将等量（按重量）的弹性体充分混合在一起。弹性体通过加成固化（铂催化）反应进行热固化。如图所示混合和固化后，合成的弹性体由交联二甲基和甲基乙烯基硅氧烷共聚物和增强二氧化硅组成。弹性体可在不进行任何后固化的情况下使用。此外，与大多数其他热固性弹性体和热塑性塑料相比，固化弹性体的热稳定性高达204°C（400°F），可进行高压灭菌，并具有较高的透气性。 Liquid Silicone Rubber (LSR) raw material for medical device and component fabrication in the Healthcare Industry APPLICATIONS Silastic® Q7-7840 Liquid Silicone Rubber, Silastic ® Q7-7850 Liquid Silicone Rubber, and Silastic ® Q7-7870 Liquid Silicone Rubber, Parts A and B, are heat-cured elastomers for use by customers fabricating medical devices, including those intended for implantation in humans for less than 30 days and non-implant applications. Silastic Q7-7840 Liquid Silicone Rubber, Silastic Q7-7850 Liquid Silicone Rubber, and Silastic Q7-7870 Liquid Silicone Rubber are two-part platinum-catalyzed silicone elastomers specifically designed for liquid injection molding or supported extrusion. The elastomer is supplied as a two-part kit (Part A and Part B), equal portions (by weight) of which must be thoroughly blended together prior to use. The elastomers are thermally cured via an addition-cure (platinum catalyzed) reaction. When blended and cured as indicated the resulting elastomers consist of crosslinked dimethyl and methyl-vinyl siloxane copolymers and reinforcing silica. The elastomer can be used without any post-cure. Furthermore, the cured elastomer is heat stable up to 204°C (400°F), can be autoclaved, and exhibits high gas permeability compared with most other thermoset elastomers and thermoplastics.	硅橡胶、HTV导管、制药和医疗保健、医疗管道、制药和医疗保健 Silicone Rubber, HTV Catheters, Pharmaceuticals & Healthcare Medical Tubing, Pharmaceuticals & Healthcare
