Rogers Venting Membranes Improves Electronics Enclosure Reliability


Reading time ( words)

Rogers Corporation is pleased to introduce DeWAL V-Series venting membranes, engineered to vent and protect a wide range of critical enclosure applications. The new line of membranes leverages the unique properties of expanded polytetrafluoroethylene (ePTFE) to enhance heat and air ventilation while protecting sophisticated electronics sealed in electrical, telecommunications, lighting, and automotive enclosures.

For today’s electronics to function reliably in the field, sealed enclosures require venting that reduces heat, protects against environmental elements, and optimizes the balance between air flow and water entry pressure. Capitalizing on the unique microstructure of ePTFE, along with its exceptional chemical resistance, low co-efficient of friction, and hydrophobic nature, DeWAL V-Series venting membranes allow continuous pressure equalization while maintaining an environmental seal. The unique membranes enable gas molecules and vapors to pass through them easily while ensuring that liquid and other contaminates are repelled. These features help prevent vents from clogging, putting less stress on the seal, and improving the long-term reliability of enclosures.

Offered in 4 standard grades of rolled goods to be converted into finished vents, the V-Series is the first line of DeWAL products developed specifically to address the challenges of enclosure venting. The unique venting membrane series is available in an expanded PTFE-only option along with ePTFE laminated to nonwoven polyester or porous ultra-high-molecular-weight (UHMW) polyethylene in two thicknesses. With enhanced mechanical stability, the laminated options can improve ease of handling and adhesive application during the traditional rotary or steel rule die-cutting and converting process.

Breanna Boyden Robbins, Product Manager for DeWAL Specialty at Rogers Corporation states, “We are pleased to introduce our first membrane series aimed at addressing the unique challenges of enclosure venting. Reliability is at the heart of everything we do at Rogers, and we look forward to helping customers choose the right venting solution to improve the long-term reliability of their products.”
