三、产品功能 / Product Functions
本品与PVC树脂相容性优异，专为硬质、半硬质PVC制品设计，核心功能稳定高效：
This product has excellent compatibility with PVC resin, specially designed for rigid and semi-rigid PVC products with stable and efficient core functions:
1. 促进塑化：降低塑化温度，缩短熔融时间，消除鱼眼、未熔颗粒缺陷，使物料熔融均匀；
1. Promote Plasticization: Reduce plasticization temperature, shorten melting time, eliminate fisheyes and unmelted particles;
2. 提升熔体强度：增强熔体延展性与拉伸强度，杜绝挤出断条、发泡塌泡、吹膜破膜问题；
2. Improve Melt Strength: Enhance melt ductility and tensile strength to avoid breaking and bubble collapse;
3. 优化产品外观：改善制品平整度与光泽度，消除表面麻点、波纹、划痕；
3. Improve Surface Quality: Increase surface smoothness and gloss, eliminate pitting and ripples;
4. 提升生产效率：优化物料流动性，降低设备负荷，适配高速挤出、注塑工艺；
4. Improve Production Efficiency: Optimize fluidity, reduce equipment load, suitable for high-speed processing;
5. 辅助分散稳定：促进填料、助剂均匀分散，减少析出、喷霜，稳定发泡制品泡孔结构。
5. Auxiliary Dispersion & Stabilization: Uniformly disperse fillers and additives, reduce precipitation, stabilize foam cell structure.
