Oil-based Electret Masterbatch

Updated: 2026-07-19

Overview

Oleophilic Fiber Electret Masterbatch is a specialized additive designed to enhance the electrostatic properties of synthetic fibers, particularly polypropylene. It is widely used in the production of electret fibers, which are essential for high-efficiency filtration applications. The masterbatch ensures uniform charge distribution, improving the filtration performance and longevity of the fibers. The product is favored for its compatibility with existing fiber production processes and its ability to maintain charge stability under varying environmental conditions. Its oleophilic nature further enhances its suitability for applications requiring oil resistance and durability.

Physical and Chemical Properties

Oleophilic Fiber Electret Masterbatch typically appears as white or off-white granules with a density ranging from 0.9 to 1.1 g/cm³. It has a melting point of approximately 160-170°C, making it suitable for extrusion processes. The masterbatch is insoluble in water but exhibits excellent compatibility with polypropylene and other synthetic polymers. Key properties include high charge stability, which ensures long-term electrostatic performance, and uniform dispersion, which prevents clumping during fiber production. These characteristics make it a reliable choice for manufacturers seeking consistent quality and performance.

Main Applications

The primary application of Oleophilic Fiber Electret Masterbatch is in the production of electret fibers for air filtration systems. These fibers are used in medical masks, HVAC filters, and industrial dust collectors, where high filtration efficiency is critical. The masterbatch enhances the fibers' ability to capture particulate matter through electrostatic attraction. Additionally, the product is used in specialized applications such as oil-resistant filters and protective clothing. Its oleophilic properties make it particularly effective in environments where oil mist or other hydrophobic contaminants are present.

Safety and Storage

Oleophilic Fiber Electret Masterbatch should be stored in a cool, dry place away from moisture and direct sunlight to prevent degradation. Proper handling includes wearing protective gloves and goggles to avoid skin contact and inhalation of dust. The product is generally stable under normal conditions but may release fumes if exposed to high temperatures. In case of accidental exposure, rinse affected areas with water and seek medical advice if irritation persists. Manufacturers should provide Material Safety Data Sheets (MSDS) for detailed safety information.
