Bonding of Plastics
Dynalab Corp custom plastic fabrication department machines products for use in laboratories, industry, education and even the home. Many plastics can be glued or bonded. There are some exceptions… traditionally Polyethylene and Polypropylene as well as engineering plastics like PTFE and Acetal are very difficult to bond. PVC will glue but, stronger joints are formed by welding. There are many types of adhesives; each with a specific purpose. First, determine the best adhesive for your application.
Dymax Corp.<> offers world class adhesives and UV curing lamps for assembly. For innovative solutions that don't stop with the adhesive please check out their website directly.

Bonding Plastic Information: |
Cyanoacrylates:
Very fast cure time. Single part adhesive that cures when confined between two substrates. |
Light-cure Acrylic & Light-cure Cyanoacrylate:
Single part adhesives that cure when exposed to a given wavelength of light. |
Hot-melt:
Thermoplastic resin "sticks" heated to melt and then when cooled form bond. |
Epoxy & Polyurethane:
Single or dual part adhesives. Strong, slow curing. Epoxy reaction heat can cause damage to some plastics. |
Two-part Acrylics:
Flexible when cured. Good for high fatigue situations. |
Solvents:
Solvent attacks and liquifies substrate and then disipates to leave joint of parent material. |
