PVDF welding rod, a fluorocarbon-based polymer featuring robust carbon-fluorine bonds, stands out for its exceptional resistance to solvents, acids, and bases. This thermoplastic material, with a melting point around 170°C and long-term usability from -40°C to 150°C, ensures durability in harsh chemical environments. Ideal for welding chemical tank liners, it protects against corrosion from strong acids, alkalis, and chlorinated solutions. In the semiconductor industry, its low outgassing properties and high electrical insulation make it perfect for sealing cleanroom pipelines and etching equipment, while its UV and ozone resistance suits outdoor applications in water treatment and aerospace fuel systems. Weldable at 320-380°C with hot air tools, it forms joints matching 85-90% of base material strength, requiring dry, degreased surfaces for optimal results.
