The welding principle of PVC plastic welding wire is based on the fusibility of thermoplastic materials: the welding wire and the material to be welded are heated to a molten state using equipment such as a hot air gun, extrusion welding machine, or high-frequency heating. Pressure is then used to fuse the two together, and a strong connection is formed after cooling. According to composition and application, PVC welding wire can be divided into general-purpose, weather-resistant, and chemical-resistant types.
General-purpose wire is suitable for ordinary welding of indoor pipes or sheets; weather-resistant wire contains UV absorbers and is suitable for outdoor environments; chemical-resistant wire has its formula adjusted to enhance its resistance to acids, alkalis, salts, and other media.
PVC materials are widely used in construction, chemical, agricultural, and environmental protection industries due to their chemical resistance, low cost, and ease of processing.
