Product Overview

PARALOID K-125 is a free-flowing processing aid designed to be readily dispersed to improve rigid or flexible PVC's fusion, flow, strength, and surface appearance. PARALOID K-125 processing aid can be used as an additive to significantly increase PVC's strength while decreasing the number of fillers needed and increasing overall production efficiency. This acrylic processing aid is used extensively in end-use building and construction materials, vinyl piping, LVT floors, and injection molding. PARALOID K-125 acrylic processing aid works best for rigid PVC extrusion applications that require fusion promotion and increased melt strength without excessive die swell. Thermoformed film packaging applications utilizing PARALOID K-125 processing aid experience exceptional hot-melt strength, shortened time to achieve a smooth rolling back, and quick fusion.  PARALOID K-125 improves processing behavior for rigid PVC with no adverse effects on impact strength, thermal stability, tensile properties, or DTUFL/Vicat properties.
