These master batches are specially engineered for improving the performance of blown films & other extrusion products in terms of optical properties, mechanical properties with reductions in the production cost.
These Master batches are based on Fluoropolymers and are widely recommended for improving the processibility of polymers at higher shear rates. These are formulated to form a microscopic dispersed phase within the polymer carrier.
During processing the fluoropolymer gets coated on the walls of the extruder and die. This reduces the extruder backpressure to decrease. To achieve the coating in a reasonable time the process aid master batch is typically added at 1% until the beneficial effects are seen. After this the addition rate can be reduced to 0.5% down to even 0.25% as long as the effect continues to be evident. A small addition must be maintained through the extrusion run.
Our quality controllers stringently check this product against several quality parameters to ensure a defect free supply at the clients’ end. Our offered PPA Master batch is known for their better output and high quality in the market.
