PE-HD, PP-H, PP-B
In addition to a wide range of sheet materials, we offer ROSTR® plastic welding rods made of the same molding compound as our sheets.
They have the same properties as, for example, operating temperature, chemical resistance, density and UV protection.
ROSTR® rods are ideal for welding our sheet material, providing long-term strength of welded joints and permanently secure connection.
Product range
Welding rod is used as filler material for welding with hot air (hot air guns) and hand extruders Leister (Weldplast, Weldmax, Fusion, etc.), Dohle, Rothenberger, HSK, Munsch, Ritmo, Widos, Rion, Eron, Forsthoff, Conex etc.
Tightness and durability are ensured not only by high-quality welding but also by the quality of the welding rod.
High quality rod has an ideal geometry, zero surface roughness, uniform color and constant diameter, has no bubbles and cavities.
A high-quality rod also provides beautiful joints and a decent appearance to the finished product.
