BLLNDX 40PCS 9.8 Inch PP Plastic Welding Rods Polypropylene Hot Air Gun Tool for Automotive Bumper Repair Rods Fenders Black

• Product Packaging: Contains 40 black plastic welding rods, each measuring 0.2 x 0.1 x 9.8 inches (5 x 2.5 x 250 mm). The ample quantity fully meets daily welding and repair needs.
• Material: Made from polypropylene (PP) plastic, offering excellent acid/alkali resistance, corrosion resistance, and good insulation properties. Its moderate melting point facilitates easy hot-melt welding.
• Usage Notes: Ensure surfaces are clean and dry before welding. After heating, the rod fuses securely with the plastic substrate for smooth repairs. Use with a dedicated plastic welder for optimal results.
• Application Method: Heat the rod and substrate with a plastic welder until molten. Press the softened rod into cracks to ensure full coverage. For reinforced repairs, insert stainless steel mesh beneath the crack before welding to strengthen the structure. Allow to cool naturally for a durable bond.
• Versatile Application: Suitable for repairing automotive bumpers, fenders, battery casings, motorcycle inner panels, plastic water tanks, and various other plastic components, combining practicality with convenience.
