Welding wire made of high-density polyethylene, PE-HD or HDPE
Polyethylene belongs to the group of polyolefins. It is the most commonly used plastic in the world. PE-HD is characterized by high chemical resistance, good electrical insulation and good sliding properties. Polyethylene is of low strength, hardness and rigidity. It has high elasticity and impact resistance.
Weakly branched polymer chains, therefore high density between 0.94 g/cm3 and 0.97 g/cm3 (“HD” stands for “high density”).
In order to connect PE parts, they are welded together, since they cannot be glued or printed without pre-treatment. All common welding devices such as hot air guns or blowers, an Injectiweld or welding extruder are suitable for this.
The biggest advantage of PE is its chemical resistance to acids, alkalis, oils and fats and it is heat-resistant up to a temperature of ~80°C. Polyethylene has a high elasticity and impact resistance and can be easily reworked by grinding, drilling and sawing.
Each roll of welding wire can be made in any RAL color.
