product description :  BASF (Germany) BASF CHIMASSORB 944/FDL is 一种 high molecular weight hindered amine light stabilizer (HALS),它具 has 优 good compatibility ,耐萃取 property and 低挥发 property 等优点,Chimassorb 944光稳定效果远 ultra- 过紫外 line 吸收 agent (如81、327等) and 含镍 stabilizer (如2002), in 颜 material 系统 in 其作用更 is significantly 。 BASF 944 and 紫外 line 吸收 agent 合用具 has 协同效果,由于聚合体 特殊结构,其平均分子量可达3000, 可 used for 要求低挥发 and 少量迁移 系统 in ,尤其 suitable for film and fiber in 。另外, BASF light stabilizer Chimassorb 944还 has antioxidant 功效,同时对 polymer 也 has 比较长期 heat stabilized 效果。
特点 and 优势:  BASF 944 high molecular weight hindered amine light stabilizer can has 效 提高薄制品 光稳定 property ,尤其 is fiber and film 制品, in 厚截面 制品 in ,它很 suitable for polyethylene (PE) 产品,Chimassorb奇妙塑944作 is 薄 and 厚制品 长期热 stabilizer 非常 has 效,并显示出 good 好 抗萃取 property 。
  • and resin compatibility 很好;

  • 容易分散于 polymer 基体 in ;

  • resin transparent property and 颜色不受影响;

  • flow property 好,无尘,易运输 and 进 material ;

  • 它 heat stabilized property and 大分子量使其 in 高温下不易挥发,不分解。

application scope :  BASF light stabilizer 944 application areas 包括聚烯烃 plastics (如PP、PE),烯烃 copolymer (如EVA)以 and polypropylene (PP) PP and elastomer 共混物。此外,CHIMASSORB 944还 can has 效 used for polyoxymethylene (POM) (POM)、 polyamide (PA) (PA)、聚氨 ester (PU)、软质 and 硬质PVC以 and PVC混合物,同时对苯乙烯类 elastomer and 粘合 agent specialty 应用也非常 has 效。
应用指引:
厚截面制品HDPE、LLDPE、LDPE and PP0.05 - 1.0%
film LLDPE、LDPE0.1 – 1.0%
扁丝PP、HDPE0.10 - 0.8%
fiber PP0.1 – 1.4%
建议 in 不使用 or 很少使用颜 material 制品 in ,以 and is improvement 某种 has 机颜 material 光牢 degree 情况下, and 紫外 line 吸收 agent (Tinuvin327/328 or Chimassorb 81)共用。
注意: 硫 or 含 halogen 素类可能会影响 BASF light stabilizer 944 效果,如 has 些 stabilizer 、杀虫 agent and flame retardant 等可能会 and Chimassorb 944 light stabilizer occurrence 反应,如需 and 此类物质共用, is 保证效果建议先进行小试。
安全指导: 遵循 good 好 工业操作规范,小心使用并避免不必要 人体接触,避免连续 or 反复吸入灰尘,仅 in 通风 good 好 环境下使用,防止环境污染,防止扬尘并远离火源。详细资 material 请参考<<化学品安全 technology 说明书>>。
