SEELYE

SEELYE welding rods are available in several thermoplastic materials, including polyurethane, HDPE (high-density polyethylene), CPVC, polypropylene, and ABS. Each type is formulated for specific applications: polyurethane for abrasion-resistant parts like conveyor belts and pump impellers; HDPE for chemical and saltwater resistance in marine and industrial structures; CPVC for chemical processing and water treatment piping; and polypropylene and ABS for general plastic fabrication and repair. Rods are supplied in round profiles with diameters such as 1/8 in, 5/32 in, and 3/16 in, and standard 48 in lengths.

SEELYE marine-grade HDPE welding rods are round, 48 in long, and come in diameters of 1/8 in, 5/32 in, and 3/16 in. They are available in white, black, and seafoam colors. Packaging is in 1 lb increments: 1/8 in rods are supplied 54 per pound, 5/32 in rods 33 per pound, and 3/16 in rods 24 per pound. These rods are formulated for resistance to saltwater and chemicals, making them suitable for repairing and fabricating HDPE structures such as boat hulls, decks, and tanks. Manufacturer part numbers include 900-18001, 900-18002, 900-18004, 900-18008, and 900-18009.

SEELYE polyurethane welding rods are used for heat welding repairs and fabrication of polyurethane components. Typical applications include conveyor belts, chute liners, pump impellers, rollers, and seals. The rods are round, off-white, and available in a 5/32 in diameter by 48 in length, packaged as 1 lb. The polyurethane material offers good abrasion resistance and flexibility. Manufacturer part numbers include 900-11200 and 900-11215. These rods are compatible with standard plastic welding equipment for hand or extrusion welding.

SEELYE CPVC welding rods are round, 3/16 in in diameter, and 48 in in length. They are gray in color and supplied in 1 lb packs containing 16 rods. The manufacturer part number is 900-13003. These rods are used for joining and repairing CPVC piping and fittings in chemical processing, water treatment, and other industrial applications where resistance to corrosive fluids is required. The 3/16 in diameter is suitable for standard welding nozzles and provides adequate fill for typical joint configurations.

Selection depends on the base material, required chemical resistance, and mechanical properties. For polyurethane parts, use SEELYE polyurethane rods. For HDPE structures exposed to saltwater or chemicals, choose marine-grade HDPE rods. For CPVC piping, use CPVC rods. Match the rod diameter to the joint size and welding equipment: smaller diameters (1/8 in) for thin sections or detailed work, larger diameters (3/16 in) for thicker sections and faster deposition. Color matching is optional but can be used for aesthetic or identification purposes. Always verify compatibility with the base polymer and follow welding procedure specifications.

SEELYE HDPE welding rods are made from high-density polyethylene, offering excellent chemical resistance, low moisture absorption, and good impact strength. They are commonly used for marine, chemical, and water-handling applications. Polyurethane welding rods provide superior abrasion resistance and flexibility, making them suitable for dynamic parts like conveyor belts, impellers, and liners. HDPE rods are typically white, black, or seafoam, while polyurethane rods are off-white. Both are supplied in round profiles and standard 48 in lengths, but they are not interchangeable; the rod material must match or be compatible with the base plastic.
