PPA Masterbatches
PPA masterbatch is a functional masterbatch based on fluoropolymers or high-efficiency processing aids, designed to enhance the processing properties of polyolefin materials such as PE, LLDPE, and PP. Polymer processing aid masterbatch reduces melt fracture and sharkskin effects while improving the surface quality of films and pipes.

PPA Color Masterbatch Mechanism
The fluoropolymer in PPA color masterbatch forms a uniform, durable lubricating film on the metal surfaces of the extruder barrel and die. This significantly reduces the friction coefficient between the melt and metal, stabilizing melt flow, minimizing melt fracture, and markedly improving film surface finish. Simultaneously, the reduced flow resistance enhances extrusion efficiency and equipment processing stability.
Advantages
- Enhance surface texture: By forming a lubricating film on the inner wall of the die, it reduces friction between the melt and the metal surface, reducing melt fracture and shark skin phenomena.
- Enhance surface gloss and flatness: Improves melt stability for more uniform flow, resulting in smooth, lustrous film surfaces free of weld lines and ripples.
- Reduce extrusion backpressure: Lowers screw backpressure by minimizing friction resistance during extrusion, enabling smoother operation and lower energy consumption.
- Improved Screen Change Pressure Fluctuations: Lubrication reduces filter resistance, enabling smoother screen changes with smaller pressure variations, enhancing filtration stability and production continuity.
- Adjustable with diverse extrusion equipment: PPA delivers stable flow performance for high-speed blown film machines, multi-layer co-extrusion lines, or narrow-slit dies, mitigating melt instability caused by extrusion speed variations.
- High cost-effectiveness: Typically, a low addition rate of 0.5–2% forms a stable lubricating layer, improving processing performance and reducing overall manufacturing costs.
- Excellent compatibility: Compatible with color masterbatches, filler masterbatches, anti-blocking agents, slip agents, recycled materials, etc., without affecting extrusion processing performance.
- Less impact on mechanical and aesthetic properties: Lubricates equipment die surfaces without altering the resin’s inherent physical properties or transparency.
PPA Masterbatch Usage Instructions
- Direct Mixing: Dry blend PPA color masterbatch with raw materials such as PE, LLDPE, HDPE, or PP according to the specified ratio. No additional equipment or process adjustments are required.
- Recommended Dosage: Typically 0.5–2% forms a stable lubricating layer. Increase slightly for high-speed film blowing or high-pressure equipment.
- Lubrication Film Formation Phase Required: Initial addition requires approximately 10–20 minutes of extrusion to allow PPA components to form a continuous film inside the die for optimal results.
- Excellent compatibility with other masterbatches: Compatible with color masterbatches, filler masterbatches, anti-blocking masterbatches, anti-static masterbatches, recycled materials, etc., without affecting product processing performance.
- No additional adjustments required: PPA master batch functions effectively within standard extrusion temperature ranges without requiring increased temperatures or screw speed modifications.
