Description
These premium MDPE welding rods are designed specifically for reliable thermoplastic repair, fabrication and maintenance work. Manufactured from high-quality medium-density polyethylene, they provide consistent melt characteristics and strong, durable welds on compatible plastic components.
Supplied in natural colour and convenient 2kg coils, these welding rods are ideal for professional plastic welders, maintenance engineers and workshop technicians working on tanks, pipework, liners and a wide range of MDPE items. Choose from 3mm round, 4mm round or 5.7mm triangle profiles to match your welding equipment and application requirements.
Product Features
- Material: premium medium-density polyethylene (MDPE) for strong, reliable welds on compatible plastics.
- Profile options: 3mm round, 4mm round and 5.7mm triangle to suit different welding guns and joint designs.
- Natural colour rods for easy visual inspection of weld quality and colour-matching to unpigmented substrates.
- Supplied in practical 2kg coils for efficient handling, reduced changeovers and convenient storage.
- Consistent diameter and profile along the coil length to promote stable feed and uniform weld beads.
- Optimised for hot air and extrusion welding of MDPE components used in industrial and engineering applications.
- Low-odour material with predictable melt flow behaviour for controlled, repeatable welding work.
Key Features and Benefits
- Ensures strong, long-lasting joints on compatible MDPE components, helping to restore structural integrity after damage.
- Choice of round or triangular profiles allows fine-tuning of weld penetration, bead build-up and root filling.
- Natural, uncoloured finish makes it easier to spot defects, porosity or contamination in the completed weld.
- 2kg coils minimise downtime from frequent rod changes and support extended welding runs in busy workshops.
- Consistent quality and dimensions reduce the risk of feed issues, helping maintain even temperature and bead formation.
- Suitable for both repair and fabrication work, providing a versatile solution for maintenance teams and production environments.

- Prototype and small-batch production work involving MDPE sheet and formed parts.
Frequently Asked Questions
Can I use these MDPE welding rods on plastics other than MDPE?
These rods are formulated for use with medium-density polyethylene and should be used only on compatible MDPE substrates for best results. Welding dissimilar plastics is generally not recommended, as it can lead to weak joints and premature failure.
Which profile should I choose for my welding application?
The 3mm and 4mm round profiles are commonly used for general repair and fabrication where standard bead sizes are required, while the 5.7mm triangle profile is often preferred for root filling, larger sections or where a broader bead and deeper penetration are needed. The best choice will also depend on your welding gun and nozzle size.
Do I need any special equipment to use these welding rods?
You will need suitable hot air or extrusion welding equipment designed for thermoplastic welding. Ensure your tools can reach and accurately control the temperatures required for MDPE, and always follow good preparation practices such as cleaning, bevelling and securing the parts before welding.
