SH—不化冰(SH系中国康复研究中心康复医学研究所医用高分子室研究开发的新材料新产品的总代号。S系Snug的缩写,含意舒适。H是Hard的缩写,意指不化冰种类中硬性类的产品。)是中国康复医学研究所医用高分子研究室1988年通过技术鉴定的高分子蓄冷材料。中国药品生物制品检定所曾对该材料进行了细胞毒性试验和眼角膜刺激试验,结果均为0级。证明该材料无细胞毒性,对人体组织和粘膜无刺激,使用安全。此材料的主要特点是:低温时冻结成“冰”,常温时保持“冰”的形状,不溢水,不化成液体,成为高强
SH-non-ice (SH Department of Rehabilitation Research Center of China Institute of Rehabilitation Medicine medical polymer research and development of new materials and new products, the general code.S Department Snug acronym meaning comfortable, H is Hard acronym Ice type of hard products.) Is China Institute of Rehabilitation Medicine Medical Polymer Laboratory in 1988 through the technical identification of polymer cold storage materials. China National Institute for the Control of Pharmaceutical and Biological Products on the cytotoxicity test and corneal irritation test results were 0. Proves that the material is non-cytotoxic, non-irritating to human tissues and mucous membranes, safe to use. The main features of this material are: frozen at low temperature, “ice”, keep “ice” shape at room temperature, no overflow, no liquid into high strength
