Sealant is often used to seal vacuum bags and mold parts. The sealing tape must have sufficient viscosity to adhere well to the surface of the mold, but it should not be so sticky that the sealing tape on the vacuum bag film cannot be torn off for repositioning. At the same time, after curing, the sealing tape must be cleanly removed from the mold surface.
The sealing tape has extremely strong adhesion to various material surfaces, and has excellent weather resistance, aging resistance and water resistance. It has the functions of sealing, damping, protecting, etc. on the surface of the adherend, and it is useful for molds and vacuum bags. The film has excellent adhesion and sealing performance, thus ensuring strict sealing requirements in the vacuum production process. The application fields of sealing tape are mainly boats, cabinets, automobiles, electrical appliances, containers, refrigerators, decoration, doors and windows, machinery, etc.
