Protape is an EPDM-based self adhesive tape, specially made for adhering the joints of elastomeric closed cell rubber insulation tubes and sheets.
- Protape provides extra holding strength to the joints and serves as a vapour barrier to prevent atmospheric moisture to penetrate through the seams. It is flexible, easy to wrap or patch tightly on the insulation surfaces.
