Description

Polyvinylidene Fluoride (PVDF) is a high-performance, semi-crystalline thermoplastic fluoropolymer. It is valued for its exceptional chemical resistance, high purity, thermal stability, and excellent mechanical properties. This material is essential for demanding applications across the chemical processing, electrical, and life sciences industries where reliability under harsh conditions is critical.

Application

• Chemical Processing Equipment: Lining for pipes, valves, pumps, and tanks due to outstanding resistance to halogens, acids, and strong alkalis.
• Wire & Cable Insulation: Primary insulation and jacketing for critical applications requiring flame retardancy, UV stability, and chemical resistance.
• Membranes for Filtration: Used in ultrafiltration and microfiltration membranes for water treatment, biopharmaceutical processing, and semiconductor manufacturing.
• Piezoelectric Films & Sensors: Key material for piezoelectric components in sensors, transducers, and energy harvesting devices.
• Architectural Coatings: High-performance resin for long-lasting, weatherable coatings on metal building panels and structures.
• Battery Components: Binder material in electrodes for lithium-ion batteries, offering electrochemical stability and adhesion.
• Pharmaceutical & Food Contact: Components and fluid handling systems where high purity, cleanability, and compliance are required.
