Welding of incompatible thermoplastic polymers

Albrecht, Mirko, Gehde, Michael 13 June 2016 (has links) (PDF)
Due to the wide range of properties of plastics (e.g. low density), more and more conventional materials are substituted by polymer materials. Complex requirement profiles on technical parts increase the demand for joining processes that enable the reliable joining of otherwise incompatible thermoplastics. In this case, material bonded connections are approaching their limits. In the following study two incompatible thermoplastic polymers were welded by using polymer blends that are compatible to both components. Industrially relevant thermoplastics polyethylene (PE) and polyamide 12 (PA12) were chosen to demonstrate the potential of an innovative joining technology.

Potentials and limitations of welding incompatible polymers

Albrecht, Mirko, Hüllmann, André, Gehde, Michael 07 March 2018 (has links)
Due to the wide range of properties of plastics (e.g. low density, low electrical and thermal conductivity), conventional materials will be increasingly substituted by polymers. Multifarious requirements on technical parts intensify the demand for joining processes, which ensure the reliable joining of incompatible thermoplastics. In this case, material bonded joints are approaching their limits. The present study focusses on the welding of two incompatible thermoplastic polymers (polyamide and polyethylene) by using adapted blend materials, which are compatible to both joining components. The results prove the feasibility of this method and indicate the high potential regarding the reachable joint strength. Furthermore, the study demonstrates the challenges regarding the suitable application of blend materials and deals with open scientific questions concerning their industrial usage.
