Polyethylene is not typically recommended for spin welding due to its low melting point and low coefficient of friction, which can make it difficult to achieve the necessary heat and pressure for proper welding. However, some manufacturers have developed specific techniques and equipment to spin weld certain types of polyethylene, such as high-density polyethylene (HDPE) or ultra-high-molecular-weight polyethylene (UHMWPE), with some success. It is recommended to consult with the material supplier and/or spin welding equipment manufacturer to determine the feasibility and best approach for spin welding polyethylene.
