Nonwoven Electret Masterbatch: Enhancing Functional Properties in Modern Applications

2025-05-15

Injection White Masterbatch & Functional Property Masterbatch Comparison

Nonwoven electret masterbatch is a specialized additive used to impart electrostatic charge retention properties in nonwoven fabrics, enhancing filtration efficiency, air permeability, and antimicrobial performance.

Organic Biodegradable Antibacterial PA/PLA/PP Masterbatch

Key Features of Nonwoven Electret Masterbatch

Electrostatic Charge Retention: Improves particle filtration efficiency (e.g., for face masks, HVAC filters).
High Melt Flow Index (MFI): Ensures uniform dispersion in polypropylene (PP) or polyester (PET) nonwovens.
Thermal Stability: Withstands high processing temperatures (180–250°C).
Additive Compatibility: Can be combined with antimicrobial or UV-stabilizing agents.
