Description
These professional LDPE welding rods in black are engineered for reliable plastic repair, fabrication and jointing across a wide range of low density polyethylene components. Supplied in convenient 2 kg coils, they provide consistent, high-quality feed for hot air, extrusion and plastic welding equipment, helping you achieve strong, clean welds on compatible LDPE materials.
Ideal for workshop, manufacturing and on-site maintenance environments, the rods are available in round and triangular profiles to suit different joint geometries and welding techniques. Whether you are repairing tanks, trays and guards or fabricating new LDPE assemblies, these black rods offer a durable, visually neat finish that blends well with dark substrates.
Product Features
- Manufactured from high-quality LDPE for compatible welding with low density polyethylene substrates.
- Available rod profiles: 3 mm round, 4 mm round, 5.7 mm triangle and 7 mm triangle for different joint types.
- Black colour for a discrete, tidy appearance on dark LDPE components and fabricated items.
- Supplied in 2 kg coil format for easy handling, storage and continuous feed to welding equipment.
- Consistent cross-section and smooth surface for stable melting behaviour and uniform weld beads.
- Compatible with common plastic welding techniques including hot air, extrusion and contact welding.
- Suitable for repairs, fabrication and modification of LDPE sheets, mouldings and profiles.
Key Features and Benefits
- Delivers strong, reliable joints on correctly prepared LDPE parts, helping extend the service life of components.
- Choice of round or triangular profiles allows better access to fillet, V-groove and corner joints for improved weld integrity.
- Black finish helps mask minor scuffs and marks, providing a professional-looking repair or fabrication line.
- 2 kg coils reduce changeovers and downtime, supporting more efficient production and repair workflows.
- Consistent material quality and dimensions support repeatable welding parameters and reduce rework.
- Versatile enough for use in workshops, fabrication shops and on-site maintenance, reducing the need for multiple rod types.

- Workshop and on-site maintenance of LDPE components in agriculture, construction and utilities.
- Prototyping and small-batch manufacture of LDPE assemblies and fabricated structures.
Frequently Asked Questions
Can these welding rods be used with any type of plastic?
No, these rods are specifically designed for welding low density polyethylene (LDPE). For a strong, reliable weld, the rod material must match the base material, so they should not be used on other plastics such as PVC, polypropylene or ABS.
How do I choose between round and triangular rod profiles?
Round rods are commonly used for general fillet and surface welds, while triangular rods are useful for filling V-grooves and providing better penetration in joint preparations. The 3 mm and 4 mm round rods suit finer work, and the 5.7 mm and 7 mm triangular rods are better for larger sections or deeper joints.
Are these rods suitable for both workshop and on-site repair work?
Yes, the 2 kg coil format and robust LDPE material make these rods suitable for both fixed workshop setups and mobile/on-site repair work, provided that appropriate plastic welding equipment and safe working practices are used.
