Description

Composite foam adhesive tape

Technical Field

The utility model belongs to the technical field of the cotton sticky tape of bubble, concretely relates to compound cotton sticky tape of bubble.

Background

The foam adhesive tape is manufactured by coating a solvent type (or hot melt type) pressure-sensitive adhesive on one surface or two surfaces of EVA (ethylene vinyl acetate) or PE (polyethylene) foam which is taken as a base material and then compounding release paper. Has sealing and shock absorbing effects. Has excellent sealing property, compression deformation resistance, flame retardancy, wetting property and the like. The product is widely applied to electronic and electric products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computers and peripheral equipment, automobile accessories, audio and video equipment, toys, cosmetics and the like. However, the existing foam adhesive tape needs to be improved in the aspects of insulation, heat resistance and the like, so that a novel composite foam adhesive tape is needed to solve the problems and meet the requirements of people.
