Blue polyester tapes with a silicone adhesive designed for high temperature applications. They can be used to break flash in composite bonding as well as splicing silicone and non-silicone coated papers and films. A 50 micron blue polyester tape with a silicone adhesive designed for high temperature applications. Specifically used as a flash breaker tape in composite bonding in addition to splicing silicone and non-silicone coated papers and films, Polyester film (PET) is one of the most common plastic films used in the converting industry due to its balance of properties in relation to other plastics. Compared to other polymeric films at a standard thickness of 25 micron, PET film has a good balance of properties, which allows larger operating windows for temperature and tension controls. Technical specifications of PET films make is suitable for use in a number of food packaging applications, including lamination and metallized packaging. It is also used in non-packaging film applications such as photographic and x-ray films, audio and video tapes, solar control films, business card laminations, industrial applications, etc. Masking tapes also a blue tape which can be used in domestic and commercial applications such as indoor painting and plastering, brushing and spraying air drying paints, masking a variety of metals, high temperature masking, protection against damage, protection and masking during sandblasting and protection against abrasion.
