产品应用： BASF Chimassorb 81二苯甲酮紫外 line 吸收 agent mainly used for plastics 行业，推荐 and hindered amine light stabilizer 结合使用， is low density and line property low density polyethylene (PE) 以 and used for 农用 film 乙烯-醋酸乙烯 ester copolymer 提供光稳定 property ，它还 can 作 is 一种紫外 line 屏蔽 agent 以保护工业品 and 消费品类 packaging materials 内容物，此外 and HALS light stabilizer 结合使用时，Chimassorb 81可 used for high density polyethylene (PE) 模塑制品，例如板条箱。
BASF 紫外 line 吸收 agent C81可 and 抗氧化 agent 、亚磷酸 ester and hindered amine light stabilizer （例如Tinuvin 292、Tinuvin 249 or Tinuvin 123）协同使用；它还 can 保护许多其他 polymer 免受光照引起 降解，例如增塑PVC and 橡胶等；
BASF 奇妙塑Chimassorb 81紫外 line 吸收 agent 熔点只 has 49℃，尽量使用 in 一些低 processing temperature 体系；当 used for coatings 时应保留Chimassorb 81 used for 对最终 coating 耐久 property 期望适 in 应用，因 is 已知2-羟基-二苯甲酮衍生物 光稳定 property has 限；
推荐浓 degree ：浓 degree 基于粘合 agent 固体 重量百分比，最佳 performance 所需Chimassorb 81 量应 in covering 浓 degree 范围 试验 in 确定。
