PVC Nitrile Closed Cell Foam Tape
Ambassador Industrials PVC/Nitrile closed cell foam tape is a high-performance sealing solution designed to maintain a reliable water seal even under minimum compression (as low as 25%). Engineered using a blend of Polyvinyl Chloride (PVC) and nitrile rubber, this foam tape offers excellent flexibility, durability, and long-term resilience across demanding industrial environments.
Its unique integral ‘skinned’ surface enhances abrasion resistance, making it ideal for applications where the tape comes into contact with sharp or rough surfaces such as metal edges, enclosures, and fabricated components.
The closed-cell structure ensures an airtight, dustproof, and waterproof seal, while its low compression set allows the material to recover its original shape even after prolonged compression. This makes Ambassador Industrials foam tape highly effective for long-term sealing applications in automotive, construction, marine, and electrical industries.

Technical Advantages
Durability & Resistance
PVC/Nitrile foam tape offers excellent resistance to UV exposure, weathering, chemicals, oils, and grease—making it suitable for both indoor and outdoor environments.
Thermal & Acoustic Insulation
Its structure provides effective vibration damping, noise reduction, and thermal insulation, improving overall system performance.
Flexibility & Strength
With strong tensile properties and elongation capability, the tape adapts easily to curves and uneven surfaces without tearing.
Electrical Safety
Non-conductive in nature, it acts as an electrolysis barrier and is suitable for electrical enclosures and switchboards.
