Polytetrafluoroethylene (PTFE) is a high-performance plastic used in a variety of industries, particularly for its heat and chemical resistance and “non-stick” properties. However, PTFE has a low surface energy that does not allow adhesives to wet its surface and subsequently bond.

Additive manufacturing (AM), also known as 3D printing, has seen increased adoption across industries and regions for producing a variety of end-use parts. 

We are using epoxy adhesives to bond steel substrates that are exposed periodically to both 150˚C and as low as 0˚C. Our problem is in maintaining adhesion to the two steel surfaces at such divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles. Do you have any suggestions?

Called thermoset polyesters, these materials are glass fiber-reinforced unsaturated polyesters. They are also often referred to as “sheet molding compounds” (SMCs), “fiber-reinforced plastics” (FRPs), or simply “fiberglass.”

Adhesives and sealants are an essential component of every equipment maintenance and reliability plan. With rapidly developing technologies and products, businesses need to stay on top of these trends. When implemented correctly, adhesives and sealants can play a critical role in improving equipment reliability and lowering maintenance and operational costs.

Vehicle manufacturers are improving fuel economy while reducing emissions by lightening the overall weight through material replacement. Using thermoplastics and adhesives instead of traditional screws and metals create less weight.
