Vacuum Sealant Tape

The vacuum sealing tape is made of advanced butyl rubber composite material, which can maintain extremely high sealing performance in the temperature range of -40 ℃ to +204℃. Whether in the vacuum forming process or in the high-pressure curing stage, this tape can effectively prevent the infiltration of air or other gases, ensuring the smoothness of the workpiece surface and the uniformity of the internal structure. Its airtightness has been rigorously tested, with a leakage rate of less than 0.01 Pa · m ³/s, far superior to similar products on the market.

This product is designed specifically for high-temperature curing processes and can maintain chemical stability for a long time at a high temperature of 204 ° C without flowing, deforming, or degrading. At the contact interface between the vacuum bag and the mold or tool, it can continuously provide stable sealing effect under high temperature and high pressure, ensuring uniform pressure distribution of the prepreg during the curing process, thereby improving the quality and mechanical properties of the final product.

Vacuum sealing tape has extremely high initial and persistent adhesion, and can firmly adhere to various material surfaces, including aluminum, steel, glass fiber, carbon fiber, and other composite materials. However, after the curing process is completed, the tape can be easily removed from the surface of the mold or tool without leaving any residue, greatly simplifying the cleaning and subsequent process operations. This feature ensures the reusability of the mold while improving production efficiency.

The dielectric constant of the aramid fiber composite is as low as ~ 3.85(10GHz), which ensures the good performance and strength of Whether in aerospace, automotive manufacturing, shipbuilding, wind power generation, sports equipment and other fields, vacuum sealing tape has demonstrated its wide application adaptability. Especially in the vacuum forming process of carbon fiber composite materials, their super strong sealing and high temperature resistance make them an important link in ensuring product quality and process safety.

Vacuum sealing tape offers a variety of thickness and width options, with common specifications including 3mm × 12mm, 6mm × 12mm, and 8mm × 12mm. It can be flexibly selected according to specific process requirements and mold design. Its standard length is 15 meters per roll, meeting the needs of most industrial applications. In addition, we also provide customized services that can adjust the size and shape of the tape according to the customer's special requirements to achieve the best sealing effect.

We attach great importance to the environmental protection of our products. The vacuum sealing tape adopts a low VOC (volatile organic compound) formula to ensure that harmful substances are not released during the high-temperature curing process, which meets international environmental standards. This not only protects the factory environment and the health of operators, but also complies with increasingly strict environmental regulations worldwide.
