ED-401A is a low molecular weight acrylic processing aid. It can be used in rigid PVC formulations to improve the process ability and the surface quality. It can accelerate fusion rate, increase productivity, decrease processing temperature, increased output rates and improved production efficiency.ED-401A has better dispersion, excellent clarity and surface quality for end-use products, superior fusion promotion for rigid and soft PVC. It is mainly used in producing PVC transparent sheets, films, etc
