What is Polyvinylidene Fluoride?

Polyvinylidene fluoride (PVDF) is a high-quality engineering plastic renowned for its durability and stability under high temperatures. It is produced without plasticizers or surface additives, making it suitable for food contact applications. PVDF is easy to weld, form, and handle, offering excellent resistance to steam and moisture. This makes it a preferred alternative to PTFE in many industrial settings.

Key Features of Polyvinylidene Fluoride PVDF

• Weldability: Easy to weld, facilitating fabrication and assembly.
• Formability: Can be formed by heat treatment for customized applications.
• Moisture Resistance: Does not absorb moisture, ensuring dimensional stability.
• Low Friction: Features a low friction coefficient, reducing wear and tear.
• Mechanical Strength: Solid and rigid, suitable for high-stress applications.
• Weather Resistance: Resistant to atmospheric conditions, ensuring longevity.
• Electrical Insulation: Excellent electro-insulation properties.
• Hygienic: Suitable for food contact applications due to its purity.
• Durability: Known for its typical long-lasting performance.
• Color Options: Available in natural (white) and black.
