Acrylic Impact Modifier (AIM) is a copolymer with the structure of core shell, the core can effectively transfer the external impact energy into heat and the shell has the good compatibility with PVC matrix, therefore it shows excellent impact-strength, weather resistance and color durability under long-period exposure to outdoor conditions.
丙烯酸酯类系列抗冲改性剂是一种具有典型的核-壳结构的高分子聚合物，其核为玻璃化温度较低的具有轻度交联的丙烯酸酯类共聚物，其壳为与PVC具有良好相容性的甲基丙烯酸酯类共聚物。

Acrylate CPE Modifier (ACM) is an unique impact modifier which is an interpenetrating network copolymer (IPN ) with the structure of CPE grafted Polyacrylate . It has balance impact strength and toughness which endow it better performance than other general type impact modifiers like CPE and MBS.
ACM低温增韧剂是一种特殊结构的互穿网络聚合物，是由CPE和具有核壳结构的轻度交联的丙烯酸酯形成的互穿网络聚合物。ACM具有更为均衡的冲击强度与韧性，适合于比较寒冷地区的使用,其耐候性比CPE/MBS更好。

Chlorinated PolyEthylene (CPE) is produced by combining chlorine and polyethylene in a process which is saturated. Linear high molecular structure enables CPE with superior physical and chemical performances.CPE has been widely used in plastics and rubber applications.
CPE作为一种优良的、有着高性价比的抗冲改性剂，被广泛地应用于硬质塑料型材、管材、管件、板材等多种硬质塑料制品以及房屋外墙披叠板、建筑防腐、防潮薄壁板的生产。CPE能够促进PVC塑化，改善加工性能，并能大大提高制品的抗冲击强度，明显改善其耐低温及耐候等性能。

Methyl Methacrylate Butadiene Styrene polymer (MBS) impact modifiers, provide superb cold temperature impacts for extrusion, injection molding and calendering. Due to its composition, MBS impact modifier is used in non-weatherable applications. Both PVC clear and opaque versions of MBS impact modifiers are available.
MBS抗冲改性剂是一种能提供优异的低温冲击强度的具有典型的核-壳结构的高分子聚合物，其核为丁苯橡胶共聚物, 因为双键的存在，MBS不能用于户外制品。MBS通用于PVC透明和非透明制品。
