At PULLMAN CHEMS, we offer advanced PPA (Polymer Processing Aid) Masterbatches designed to significantly enhance the processing performance of polyolefins, especially during high-speed film extrusion and blown film manufacturing. PPA masterbatches improve polymer melt flow, reduce surface defects, and boost overall production efficiency—making them essential for achieving smooth, high-quality outputs.
What is PPA?
PPA (Polymer Processing Aid) is a fluoropolymer-based additive that helps reduce die build-up, melt fracture, and gel formation during the extrusion process. It forms a thin lubricating layer on the metal surface of the extruder die, minimizing friction between the polymer and the equipment.
Key Benefits:
-
Improves Surface Quality – Eliminates melt fractures, shark skin, and flow lines in film and sheet applications.
-
Reduces Die Build-Up – Keeps the die clean, reducing downtime and maintenance costs.
-
Increases Output – Enables higher line speeds and smoother processing.
-
Enhances Gel Elimination – Helps in removing unmelted polymer gels and improves product clarity.
-
Improves Additive Dispersion – Ensures better mixing of pigments and functional additives.
Applications:
-
Blown film (LDPE, LLDPE, HDPE)
-
Cast film and stretch film
-
Pipe and tubing extrusion
-
Wire and cable coating
-
Injection molding and sheet extrusion
Compatibility:
Our PPA Masterbatch is specially formulated for use with PE (LDPE, LLDPE, HDPE), PP, and other thermoplastic polyolefins. It is easy to use, effective at low addition levels (typically 1–3%), and highly thermally stable.
At PULLMAN CHEMS, our PPA Masterbatch ensures smoother production, superior surface finish, and higher throughput, making it an essential choice for manufacturers aiming for operational excellence and top-tier product quality. Let PULLMAN CHEMS optimize your process—one pellet at a time.
