✅ product features
BASF BASF Uvinul 4050/FF is 一种 low molecular weight hindered amine light stabilizer ,应 used for plastics 、橡胶等高分子 material material 防老化,其光稳定效果 is 传统吸收 type light stabilizer 2~4倍,Uvinul 4050具 has good 好 易分散 property 且 and 许多 resin 具 has good 好 compatibility , and 紫外吸 line 收 agent 相比, low molecular weight Uvinul 4050不依赖于 polymer 厚 degree ,它 is 厚截面提供出色 光稳定 property ,但也可 used for 具 has 高表面积 物品,如 film and 胶带, in fiber and 注射 plastics in 应用也很 has 效,尤其 suitable for 厚 wall polypropylene (PP) PP模塑制品, polypropylene (PP) PP fiber ,聚烯烃等, BASF 4050 light stabilizer and 颜 material 具 has good 好 compatibility ,对 plastics processing properties 无不利影响。
main applications : BASF light stabilizer 4050推荐 used for polystyrene (PS) , impact resistant polystyrene (PS) ,ABS、SAN、ASA、 polypropylene (PP) 、 impact modified polypropylene (PP) (TPO)、EPDM ternary 乙丙橡胶 and polyamide (PA) 等 plastics polymer 。Uvinul 4050可单独使用 or and high molecular weight light stabilizer HALS结合使用,如Chimassorb or Uvinul HALS,以实现协同作用效果, and 苯酸盐类紫外 line 吸收 agent 、受阻酚 antioxidant 具 has 较好 协同作用 can 提高PP,HDPE weather resistance and 色牢 degree 。
使用指南: 建议 浓 degree 范围 in 0.1%到0.5%之间,具体取决 in 于基体上, processing conditions and 应用 具体情况。Uvinul 4050 hindered amine light stabilizer 根据要求可 used for 多种基质 and 多种 applications ,可 used for and food contact plastics 制品。
什么 is light stabilizer : light stabilizer (英文名称Light stabilizer;photostabilizer) is 高分子制品(例如 plastics 、橡胶、 coatings 、合成 fiber ) 一种 additives ,它能屏蔽、反射紫外 line or 吸收紫外 line 热能,猝灭被紫外 line 激发 分子 or 基团 激发态,使高分子 polymer in 光 辐射下,能排除 or 减缓光化学反应可能 property ,阻止 or 延迟光老化 过程,从而达到延长高分子 polymer 制品使用寿命 目 。
light stabilizer 按其作用机理可分 is 光屏蔽 agent (也叫光遮罩 agent )、紫外 line 吸收 agent 、猝灭 agent and hindered amine light stabilizer (hindered amine light stabilizer,简称HALS)四类。
工业上对光老化 has 效防止 and 阻缓,多以两种以上 has 不同作用机理 light stabilizer 复配,对不同波段紫外 line 进行吸收, can 起到单一 light stabilizer 所无法达到 优秀效果。
操作 and 安全: 避免不必要 直接接触,避免连续 or 重复 呼吸灰尘,只能 in 通风 good 好 情况下使用,避免 and 眼睛接触,避免释放到环境 in ,避免 powder 尘形成 and 火源, has 关更多详细信息,请参阅 material material 安全数据表。
