“紫外线吸收剂UV329 防老化剂 厂家直销”详细介绍
紫外线吸收剂
产品名称 紫外线吸收剂 UV-329 UV Absorber UV-329
化学名称 2-(2'-羟基5'-叔辛基苯基)苯并三唑
Chemical Name 2-(2'-Hydroxy-5'-tert-octylphenyl)benzotriazole
CAS NO. 3147-75-9
分子式 C20H25N3O 分子量 323.44
化学结构图
质量指标Specification 外观 白色粉末
透光率 460nm 98.0%min 500nm 99.0%min
挥发分 ≤0.3%
灰分 ≤0.1%
熔点 103~105℃
含量 ≥99%
用途
Application 白色粉末或结晶,溶于氯仿、二氯甲烷、甲苯,微溶于丙醇类,不溶于水。苯并三唑类紫外线吸收剂是一高效光稳定剂,挥发性很低,与许多聚合物的相溶性很好。适用于聚苯乙烯、聚甲基丙烯酸酯、不饱和聚酯、硬质聚氯乙烯、聚碳酸酯、ABS 树脂等,在透明制品及高温加工的工程塑料中尤具效果。用量一般为 0.1-1%。
UV-329 is a white powder,melting point 103-105°C,soluble in benzene,styrene,ethye acetate,slightly soluble in ethyl alcohol,insoluble in water.It is an efficient light stabilizer,UV max:345nm,low volatility,used for polyetyrene,poly(methyl methacrylate),polyester and ABS resins and so on.
储存
Storage 避免阳,光高,潮湿,避免含硫或含卤族元素的光稳定剂。需要在密封干燥避光条件下储藏保存。This product may be stored for one year in a sealed container.Containers should be stored in a cool,dry area.Extended storage at elevated temperatures or exposure to direct heat or sunlight could reduce product life.Keep containers sealed when not in use.
包装
Packing 纸板桶内衬塑料袋,25公斤/桶。
