What is PVDF?
Polyvinylidene fluoride (PVDF) is a semi-crystalline fluoropolymer. This thermoplastic exhibits excellent chemical resistance, mechanical properties, and thermal stability. PVDF is composed of repeating vinylidene fluoride units, and its strong internal carbon-fluorine bonds give it a unique combination of properties.
Typical applications for this material include corrosive environments that require both the chemical resistance of fluoroplastics and higher mechanical properties than polytetrafluoroethylene (PTFE) or polytetrafluoroethylene (PCTFE). PVDF can be used at temperatures up to 300°F (approximately 149°C). PVDF is white and is available in a variety of sizes.

PVDF Injection Molding Principle and Process
Inside the injection molding machine barrel, PVDF material melts into a flowing molten material under the action of heat and shear force. This molten material then flows into the closed mold cavity under the thrust of the plunger or screw for molding. After cooling and solidification, the mold is opened and the product is removed. The key to the molding process lies in heat transfer under pressure and melt flow, which are closely related to factors such as the viscosity, thermal stability, thermal conductivity, crystallinity, and moisture content of the PVDF material.
PVDF injection molding typically uses screw-type injection molding machines with a screw length-to-diameter ratio of 20:1 to 25:1. Parts in the injection molding machine that frequently come into contact with the molten resin should be made of corrosion-resistant materials. The diameter of the main mold channel should be approximately 1 mm larger than the nozzle, ideally thick and short, with uniform mold cavity wall thickness and avoidance of sharp corners to reduce flow resistance.
PVDF Injection Molding and Molds
Our in-house injection molding plant utilizes state-of-the-art machinery, equipment, and mold technology to process PVDF, ensuring superior performance of finished PVDF components. We ensure precise and gentle processing of PVDF materials. PVDF melt must never come into contact with boron-containing products (screws, barrels, certain glass fibers) or molybdenum disulfide (MoS₂), as this will cause spontaneous melt decomposition. Therefore, all PVDF polymers and compounds are fed directly into the injection molding machine and processed in specially coated screws and injection units.
