Protape®

Description

Aeroflex® Protape® EPDM Seam Tape is a zero-perm, 24-mil thick EPDM rubber tape designed for vapor-sealing glued seams of AEROFLEX® EPDM closed-cell elastomeric insulation. This durable, self-extinguishing tape provides a reliable vapor barrier to prevent water vapor ingress, minimizing the risk of corrosion under insulation (CUI). Protape® is available in black and white/gray color options for use in HVAC, refrigeration, VRF, chilled water, and hot/cold-water piping applications.
