  • Patent number: 6610411
    Abstract: A protective tape used to protect an electrical connection from the effects of ultraviolet radiation. The protective tape comprises a silicone gel that contains a UV inhibitor such as zinc oxide. The protective tape is used to wrap a connection, such as a coaxial connection, in order to provide a long lasting, secure environment for the connection and to shield against the effects of UV radiation that can otherwise cause a deterioration of tape. As one embodiment, the silicone gel is a two layer gel with each layer having a different hardness. The tape is formed by casting the silicone gel on a suitable backing and that backing is removed from the tape at the time the tape is used to wrap around the electrical connection.

    Abstract: The present invention provides a method of preparation for a degradable, water and oil resistant protective membrane. In the said method, carbon dioxide copolymer is dissolved in a low toxic or non-toxic solvent to form a solution of 3-6 wt % concentration. After standing and filtration to remove metal oxide, the solution is used to coat the surface of the fabricated starch, paper pulp, or straw tableware by spraying or dipping. The residual solvent is removed by drying process and a degradable, water and oil resistant and transparent protective membrane is obtained. The thickness of the protective membrane is in the range of 10-20 micrometer. Metal ion content is lower than 1 ppm. No leakage and deformation of the tableware are observed after the tableware is immerged in water or edible oil for 4 hours at 80° C. The decoloration test by cold edible oil and ethanol is negative.
