  • How do you distinguish between primary and secondary raw materials?

    Primary vs. Secondary Raw Materials The fundamental distinction lies in the origin and processing history. Primary raw materials are extracted directly from natural resources (ores, crude oil, forests) and have never been used or processed industrially before. Secondary raw materials are recovered from pre-consumer or...

PVDF raw material particles Industry knowledge

What are PVDF raw material particles?

1. Definition: PVDF (polyvinylidene fluoride) raw material particles refer to white or semi-transparent powdered polymers obtained through polymerization processes. The chemical formula is –(C₂H₂F₂)ₙ–. They are commonly used in injection molding, extrusion, and compression molding to produce high-performance products such as pipes, valves, and membranes.

2. Morphology and Specifications: Particle sizes range from 10µm to 200µm. Different molecular weights and purities (≥99.5%) can be formulated according to customer needs to meet the stringent requirements of industries such as aerospace, semiconductors, and photovoltaics.

3. Applications: In fields such as solar photovoltaic modules, semiconductor manufacturing, chemical pipelines, ferroalloy smelting, environmental protection, pharmaceuticals, and aquaculture, PVDF particles are key raw materials due to their resistance to chemical corrosion, high temperature resistance, and excellent electrical insulation properties.

What are the main chemical and physical properties of PVDF raw material particles?

1. Chemical Properties

Molecular Structure: The repeating unit is –CH₂－CF₂－, giving the material excellent chemical inertness and resistance to acids, alkalis, halogens, and most organic solvents.

Corrosion Resistance: Within a wide temperature range of -40℃ to 150℃, PVDF exhibits extremely low permeability to fluorides, strong oxidants, and weak alkalis, making it suitable for pipes and valves in highly corrosive environments.

2. Physical Properties

Density: 1.74~1.80 g·cm⁻³, classifying it as a medium-density engineering plastic.

Melting Point and Thermal Stability: Melting point approximately 172℃, thermal decomposition temperature above 390℃, maintaining structural integrity during high-temperature processing.

Mechanical Properties: Tensile strength and impact toughness are superior to ordinary polymers, possessing good wear resistance, aging resistance, and UV resistance, making it suitable for long-term piping systems.

Electrical properties: It has a dielectric constant of about 5.6, high dielectric strength, and a piezoelectric/ferroelectric phase (β-phase) that enables self-sensing function, making it widely used in sensors and energy harvesting devices.
