Overmoulding Materials

OVERMOULDING MATERIALS for electronics, cables and PCBs

Here at Overmould Ltd we use a variety of over-moulding materials depending on the application requirements; Polyamide Adhesive Thermoplastics enable you to mould in any shape around electronics, cables and PCBs. We also provide other materials such as Epoxy potting & RTV Silicone, when the application dictates the need for a different material.

Technomelt® products melt and flow at low viscosities (1,000 to 10,000 cps), facilitating the low injection pressure process and providing perfect and safe alternatives to encapsulation and potting. Technomelt® offers excellent adhesion to various substrates, including PVC, PA6.6, PUR, and PP. Since they are based on adhesive technology, they bond to form a watertight and chemical seal. These hot melts cure quickly by cooling so there are no toxic fumes and cycle times are short. The entire line of Technomelt® OM products is UL94-V0 rated.

At Overmould, we can supply the materials in amber, black and a variety of custom colours.
