Product Description

• Made of high-quality industrial polypropylene, this plastic cartridge features strong corrosion resistance against silicone sealants and common adhesives. It maintains stable structure without swelling or degrading during long-term storage, protecting sealant performance and supporting continuous use in harsh construction and maintenance environments.

• The transparent PP design lets operators directly view the remaining sealant inside the plastic cartridge. Users can arrange refills in advance, avoid sudden material depletion during caulking work, reduce waste, and improve working efficiency for both mass production packaging and on-site sealing operations.

• Equipped with reliable sealing matching parts, the sealant cartridge blocks air and moisture infiltration effectively. It prevents silicone sealant from skinning, premature curing or leakage in transportation and storage. This stable barrier keeps the sealant original property intact and lowers product reject rates for adhesive manufacturers.

• This 300ml plastic cartridge follows industry standard dimensions, perfectly matching most manual and pneumatic caulking guns on the market. It delivers smooth, consistent dispensing with minimal residue left inside the tube, maximizing sealant utilization and bringing neat, precise caulking results for all sealing projects.

• Developed for silicone sealant packaging, it fits industrial construction, automotive repair, window & door installation and household DIY caulking tasks. The lightweight yet tough plastic cartridge stands rough handling on job sites, serving as a dependable packaging solution for adhesive brands across diverse sectors.
