Processing Aid It can improve the process ability of PVC by promoting fusion with the breaking down of PVC particles, at below the degradation temperature. it can be used in rigid PVC formulation to improve process ability and the surface quality. 1) Accelerated fusion rate, increased productivity and decreased processing temperature. 2) Better dispersion of additives into PVC, more homogenous melt of PVC, etc. 3) Excellent clarity and surface quality for end-use products, superior fusion promotion for rigid and soft PVC. Increased output rates and improved production efficiency.
