  • Vent material in your required format

    The non-adhesive vent material range includes hydrophobic products, for preventing the ingress of water, and oleophobic products which operate in the same way, but resist ingress of oils and other low surface tension fluids.

    Vent material is available in sheet and roll form, or can be laminated with a zone coated adhesive and die-cut to your requirements. This doesn’t have to cost more than an ‘off the shelf’ part, in fact, our bespoke service is often better value for money; reducing your design and testing costs, improving manufacturing efficiencies and enhancing the quality of your products.
