Plastics manufacturers are all too familiar with the challenges of bonding thermoplastics. Last week, BTG Labs successfully hosted a webinar with Plastics Technology to discuss improving bonding of thermoplastics. The webinar, entitled “Understanding Surface Energy: How to Measure and Control the Surface Properties of Thermoplastics to Maximize Adhesion,” brought in almost 400 registrants.

Presented by BTG Labs’ Chief Scientist Dr. Giles Dillingham who discussed the surface characteristics of thermoplastics. Dr. Dillingham also explored surface treatment processes such as flame, corona, and plasma, and ways to monitor and verify those processes. The ability to understand and measure the surface precisely is the key to successfully bonding thermoplastics.

This table shows the relationship between low surface energy and relative interfacial toughness. While thermoplastics are highly durable, they cause difficulties in bonding because of their low surface energy.
