Processing Aid for Flexible PVC LP-550 is a processing aid based on a low molecular weight polymethacrylate resin. LP-550 can be used in rigid PVC formulations to improve the process ability and the surface quality.

Physicochemical Properties

LP-550 is White free-flowing powder, bulk density:0.30-0.55g/cm3, can not be dissolved in water, ethanol, can be dissolved in chloroform and methyl ethyl ketone.

Product Benefits and Application

◆Accelerate fusion rate, increase productivity and decrease processing temperature.

◆Better dispersion of additives into PVC, more homogenous melt of PVC, etc.

◆Excellent clarity and surface quality for end-use products, superior fusion promotion for rigid and soft PVC. 

◆Increased output rates and improved production efficiency.

◆LP-550 is widely used in the processing of many rigid and flexible PVC products made by blow molding, calendering, extrusion and injection molding. Key applications include: PVC Sheets, film, bottles, profiles, pipes, pipe fittings etc.
