丙烯酸加工助剂(ACR)
关于此产品
丙烯酸加工助剂是一种高分子量甲基丙烯酸酯共聚物,添加量为每百份树脂数份。它溶解于PVC熔体中,提高熔体的内聚强度和弹性。 其作用在于塑化。PVC在加工中呈部分塑化的颗粒状态,而非真正均质的熔体;丙烯酸加工助剂可加速这些颗粒界面的破坏,使给定温度下的凝胶化更为充分。塑化更充分的熔体具有更高的熔体强度,凡是挤出物必须自我支撑的场合都需要这一点:发泡制品中泡孔不得塌陷;吹塑成型中型坯必须悬垂;压延与热成型中片材必须均匀拉伸。 最直观的效益是表面质量,因为塑化不足会表现为表面粗糙、光泽不良和口模流痕。JX-LP-551为低分子量丙烯酸加工助剂,以白色自由流动粉末供应,25 kg/桶,1 MT/托盘,10 MT/20英尺集装箱,用于硬质PVC以改善加工性能和表面质量。所经销的K系列涵盖通用级K-120P、K-125P和K-130P,润滑型K-175P以及高分子量级K-400P,以20 kg袋装供应。
