For example, polypropylene is inexpensive with high chemical resistance, but is hard to bond due to its low surface energy. Nylon is more expensive, resists wear and heat, and is easier to bond given its high surface to high surface energy An unwaxed car hood exhibits high surface energy (HSE) and water spreads across the surface.

7 Similar to water, adhesive on a high energy surface flows and wets out the surface. Wetting is necessary for effective bonding. A waxed hood exhibits low surface energy (LSE). In effect, the energy of the wax repels the water, forcing it into beads. adhesive also beads up and does not effectively wet an LSE bonding success with LSE thermoplastics, 3M offers several specially formulated adhesives and tapes. Using the selection chart This Guide focuses on thermoplastics because of their complexity, versatility, and wide use. Thermoplastics are presented in the adjacent chart, moving left to right from low to high surface energy.

8 At the intersections of 3M technology and plastic, 3M product numbers represent starting points for further more wherever people live, work, or playIn 1976 plastics had become the most commonly used material in the world. By 2001 plastics was the fourth largest manufacturing segment in the United States. Today, wherever you live, work, or play, the use of plastics is growing, and with it the use of 3M adhesive and tape technologies to assemble, protect, and label products made of plastics or plastics combined with metal, wood, or other adhesive and tape benefits Bond strength matched to the job, for example, replacing screws and other mechanical fasteners.

9 Bonding LSE plastics with little or no surface preparation Virtually invisible fastening for an aesthetically-pleasing product Increased material options bond more plastics than ever, including inexpensive hard-to-bond plastics Increased manufacturing efficiency with faster assembly speed and fewer assembly steps in many applications Bond and seal simultaneously This Guide is an overview to help you match 3M technologies to specific thermoplastics for applications of plastics Thermoplastics are polymers that can be repeatedly softened with heat for molding, becoming solid when cooled.

10 Thermosetting plastics soften with heat once, then cool to an insoluble solid. Thermoset parts are easily bonded, while thermoplastics have a wide range of surface energy characteristics which must be considered for successful bonding or labeling.
