Vacuum sealing adhesive tape is an adhesive and elastic tape
takinga special synthetic rubber as the butyl, and made of some
assistancemainly including the temperature-resistance reinforcing
agent andtackifier. This material is able to better adhere to
steel, aluminum,nylon and other metals and nonmetal as well. It
features good temperatureresistance, convenient usage, reliable
high-temperature sealing. Typical application It is used for high-temperature vacuum molding sealing of
materialssuch as composites and safety glass. Technical data 1. Density: less than 1.4g/cm3 2. Shear strength: not less than 0.07Mpa for aluminum / nylon film 3. Heat-resistance: with the treatment of 4 hours, the tape is
freeof diaspora, crack keeps its original thickness. 4. High-temperature peel strength: with the treatment of 1803hours,
its peel strength will be less than 1.5Kg/M and can stripfrom the
mental surface. Usage method 1. Remove the oil and dust on the surface of the sealed mental
andnylon membrane, and clean with 120 # gasoline. 2. Paste one side with the adhesive tape on alloy surface aroundthe
vacuum tank evenly, remove the release paper of the adhesivetape
and then paste the nylon membrane on the adhesive tape, pressevenly
with small stick (avoiding introducing bubbles) to make theadhesive
tape firmly bond on the upper and lower parts. In addition,pumping
vacuum will be conducted to check the reliability of thesealing,
and then it can be used for high temperature vacuum molding(it can
also be used for high temperature molding after consolidatingpaste
and sealing of the adhesive tape upon the different requestsof the
users).
