Processing Aid Masterbatches
Improving the processability and aesthetic properties of extruded films, sheets and mouldings, both fluoropolymer and PFAS free options available.
Improving melt processability and aesthetics of polymers.
Polymer processing aids are designed to improve the melt processability and handling of high molecular weight polymers. They can also give finished articles improved aesthetic properties by removing flow marks and die lines thereby improving the parts gloss and clarity.
Processing aids find use in a wide variety of applications from blown film to fibre, profile extrusion, pipe/tubing and cabling processes. They can be used with many polymers including LDPE, LLDPE, HDPE, mLLDPE, PP, polystyrene, ABS and others.
How it works.
Wells processing aid masterbatches are based on a variety of technologies depending on the requirements of the end application and regulatory constraints.
Technologies used include both high performance fluoropolymer and innovative PFAS free systems.
Polymer process aids masterbatches are designed to provide a dynamic low friction surface coating on the extruder screw, barrel, and die which enables the polymer melt to pass through with less resistance. This ease of flow helps to reduce pressure and motor torque within the extruder giving the processor scope for energy savings.
In addition to potential cost savings polymer processing aids also improve the aesthetic appearance of the product and can extend up time.
In blown and cast film extrusion, processing aids are predominantly used to reduce melt fracture (sharkskin) and die lines, and to promote reduced gel formation and cleaner running. This enables the processor to run longer between stops for dies cleaning.
In sheet and profile extrusion, and in extrusion blow moulding, the processing aids main functions are for low die build up, removal of die lines, and for faster colour change over times.
Wells processing aid masterbatches are very effective, even when used at very low addition rates.
