Description

Technical Field

[0002] Carbon fiber tape is made of PET as the base material, with reinforced carbon fiber lines inside and coated with special pressure-sensitive adhesive. Carbon fiber tape has excellent wear resistance and moisture resistance, extremely strong breaking strength, and the unique pressure-sensitive adhesive layer has excellent long-lasting adhesion and special properties. Carbon fiber tape is composed of two parts: base material and adhesive. It connects two or more unconnected objects together through bonding, and a layer of adhesive is coated on its surface; the adhesive can stick to things because bonds are formed between its own molecules and the molecules of the objects to be connected, and this bond can firmly bond the molecules together; the tape production process is generally to put the plastic film on the coating machine to apply glue, and then pass the plastic film coated with glue through the rewinder to rewind it into a film.
