Plastic Welding: Splicing of Thermoplastic Materials

SpecialChem / Mar 21, 2008

A long time before there was welding, bolting or soldering, there was splicing. Splicing is the oldest and one of the simplest ways of joining two pieces together. People in the Stone Age were the first users of adhesives. They used a mixture of bees-wax and birch sap to fasten arrowheads by using a hot stone wedge as a soldering iron. Over the centuries, the use of adhesive materials has advanced considerably. The following will provide you with an overview of the six basic types of adhesives that can be used when hot-air or extrusion welding is not an option for the joining of thermoplastic materials. The concept of splicing involves the connection of pieces by using the surface adhesion between the parts and the adhesives' firmness or cohesiveness.One of the best features is an even distribution of stress. Additionally, totally different materials can be brought together, large splicing areas can be made quickly, and the adhesive itself fills uneven surfaces. On the other hand there are some features that are not as desirable.
