No, LDPE welding rods should not be used with other types of plastic. LDPE, or Low-Density Polyethylene, has specific chemical and physical properties that make it incompatible with other plastics during the welding process. Each type of plastic has a unique melting point, chemical structure, and thermal expansion rate, which are crucial for achieving a strong weld. Using LDPE rods with other plastics like HDPE, PVC, or ABS can result in weak joints, poor adhesion, and potential failure of the weld. For effective plastic welding, it is essential to match the welding rod material with the base material to ensure compatibility and structural integrity.

The temperature required for welding Low-Density Polyethylene (LDPE) plastic typically ranges from 120°C to 160°C (248°F to 320°F).
