Direct Answer: Additive masterbatches are concentrated functional compounds added during plastic processing to enhance performance, extend product lifespan, improve optical clarity, or optimize extrusion throughput.
1. Key Additive Categories
Barjatya Polychem manufactures 10 verified functional additive masterbatch lines:
- Optical Brighteners (OB): Fluorescent agents that absorb invisible UV radiation and re-emit blue-violet light to eliminate yellowish polymer cast.
- Blowing Agents: Chemical foaming agents that generate microcellular structures to reduce product weight and eliminate sink marks in thick-walled mouldings.
- PP Clarifying Agents: Nucleating compounds that accelerate crystal formation, significantly boosting transparency in polypropylene containers and cups.
- Antistatic Agents: Formulations that migrate to the polymer surface, dissipating electrostatic charges and preventing dust accumulation.
- UV Stabilizers: Hindered Amine Light Stabilizers (HALS) and absorbers that shield outdoor plastics from sunlight degradation.
- Antioxidant MB: Primary and secondary phosphite blends that protect polymer chains from thermal degradation during compounding and service life.
- Polymer Processing Aid (PPA): Fluoropolymer concentrates that coat extruder dies, eliminating melt fracture (sharkskin) and lowering head pressure.
- Slip & Antiblock: Erucamide/oleamide and synthetic silica blends that reduce surface coefficient of friction (COF) and prevent film blocking on rolls.
- Flame Retardants: Halogenated and halogen-free compounds that delay flame propagation for electrical appliances and cable conduits.
