Polymer Proceesing Aid(ppa)
Polymer Processing Aid Masterbatches also known as PPA reduces the die build-up in most of the processes and eliminates melt fracture in films. So PPA masterbatches help in increasing the process ability of plastics like Pipes, Tubes, and Polyethylene films. It also helps in increasing the throughput rates along with improvement quality.
The most common and widely used processing aids are Fluro elastomer based. These additives along with sufficient quantity of Antioxidants allows smoother processing even at higher rates. You get to create a microscopically dispersed zone using this material and right within the polymer carrier.
The addition of PPA creates a thin layer of film between the metal parts and the molten material . It reduces the back pressure inside the extruder. Higher addition level of PPA masterbatch is recommended in the starting of the process which will clear most of the burned particles inside the extruder and stabilize the process. PPA dosage can be reduced to 0.5-1% levels for smooth processing. Be sure to maintain a smaller addition throughout the entire extrusion run.
PPA masterbatches allows higher throughputs even at lower temperatures thereby maintaining mechanical properties and surface gloss. Continuous use of POLYMER PROCESSING AID MASTERBATCHES can give long term benefits like lower wastage, low rejections and reduced barrel wear.
Properties
- Reduce electricity consumption due to reduced back-pressure in the extruder.
- Increase production rates upto 20%
- Reduce optical defects
- Reduce the die build-up
- Eliminates melt fracture & shark skin effect
- Optimization of extruder process lead to increase in output along with enhanced and bi-directional physical properties and improved clarity and gloss.
