tesa® 4773
Product description
tesa 4773 is a 6mm thick premium grade closed cell PVC nitrile foam tape with an acrylic adhesive on one side. The closed cell foam can create a water proof barrier when compressed, while the PVC nitrile construction ensures high resistance to abrasion, weathering, UV, ozone, petrol, oil, acids, solvents and many chemicals, making it an ideal solution in tough environments.
tesa 477 Series foam tape is electrically non-conductive and can be used as an electrolysis barrier, and is flame retardant to FMVSS 302. tesa 477 Series is available in 4mm, 6mm, 9mm and 12mm thicknesses in the colour black.
