PBT bonding solution

PBT is a thermoplastic which is commonly used to make injection moulded parts for automotive, electrical and medical industries. However, certain blends prove particularly difficult to bond. Recently released Permabond ES5741 has been developed to bond even the most challenging blends of PBT, offering good adhesion, high strength structural bonds and high temperature resistance. The product has been found to work well on a number of filled varieties of PBT where other adhesives have shown poor adhesion characteristics. Many parts manufacturers have previously resorted to using ultrasonic, friction or spin welding joining methods; these are not only costly but they also restrict the choice of materials being joined being unable to bond PBT to metal for example. The dimensions, fit and geometry of the joint are also limited. ES5741 enables easy bonding of PBT to other materials such as other types of plastic, phenolic and various metals.
