PE welding rod (polyethylene welding rod) is mainly used for welding thermoplastic materials (such as polyethylene, polypropylene, etc.), and is commonly used for connecting and repairing pipelines, containers, and plates. The following is a detailed description of its performance characteristics and main uses:

1、 Performance characteristics of PE welding rod
1. Material compatibility
-Chemically compatible with substrates such as HDPE, LDPE, PP, ensuring that the strength after welding is close to that of the base material.
-Select the corresponding welding rod based on the type of plastic being welded (e.g. PE welding rod cannot be used for PVC welding).

2. Thermal performance
-The melting temperature is low (about 200-300 ° C), and it needs to be heated with a dedicated hot air welding gun or extrusion welding machine.
-After melting, it has good fluidity and can fill gaps. After cooling, it forms a uniform weld seam.

3. Mechanical properties
-The tensile strength and impact resistance are close to those of the base material, but the quality of the weld seam is greatly affected by the welding process.
-Excellent corrosion resistance, suitable for corrosive environments such as chemical and sewage treatment.

4. Environmental friendliness
-No toxic volatiles, but it needs to be operated in a ventilated environment to avoid melting smoke.

2、 The main use of PE welding rod
1. Pipeline welding
-Municipal engineering: socket welding or butt welding of HDPE water supply and drainage pipelines and gas pipelines.   
-Industrial pipelines: Sealed connections for chemical fluid transportation pipelines.

2. Containers and storage tanks
-Welding PE material for chemical storage tanks, acid pickling tanks, sewage treatment equipment, etc.

3. Panel splicing and repair
-Overlapping welding of impermeable membranes (such as geomembranes) and repair of plastic sheets (such as water tank linings).

4. Special applications
-Produce plastic anti-corrosion lining, weld plastic inspection wells, biogas digesters, etc.
