S71U是一种高透明度等级的硅橡胶,用于食品、乳品、酿造、饮用水、制药和生物医学应用。铂固化硅树脂无臭、无味、无毒。由S71U制成的密封件能够抵抗这些行业常用的反复消毒、高压灭菌和清洗剂。与传统的过氧化物固化方法不同,铂固化可获得光滑的接触表面光洁度和高纯度。在制造过程中,不产生苯甲酸、过氧化物、酮等残留物质,这些物质可以从密封件转移到重要的卫生产品上。关键属性符合FDA CFR210177.2600,用于干、水和脂肪食品。符合USP六级后缀87和88,生物反应性试验。良好的机械和物理性能,在-60°C至+200°C的温度范围内具有化学稳定性。能承受无菌和高压灭菌程序,不含动物源性成分(ADI),典型应用,食品加工和包装设备,制药和生物医学设备,乳制品设备卫生密封,饮用和高-纯水应用 S71U is a high transparency grade of silicone rubber intended for use in food, dairy, brewing, potable water, pharmaceutical and biomedical applications. Platinum-cured silicone is odourless, tasteless and non toxic. Seals made from S71U are resistant to repeated sterilising, autoclaving and cleaning agents commonly used in these industries. Unlike traditional peroxide-cure methods, platinum curing results in a smooth contact surface finish and a high degree of purity. No residue substances such as benzoic acid, peroxides, ketones are produced during manufacturing, which can be transferred from the seal to critical hygienic products. Key Attributes Compliant with FDA FDA CFR210177.2600 for use with dry, aqueous and fatty food stuffs. Conforms to USP class VI suffix 87 and 88, Biological Reactivity tests. Good mechanical and physical properties Chemically stable over a temperature range of -60°C to +200°C. Withstands sterilizing and autoclaving procedures Free from Animal Derived Ingredients (ADI) Typical Applications Food processing and packaging equipment Pharmaceutical and biomedical apparatus Hygienic seals in dairy equipment Potable and high-purity water applications |
