Product Description

• This plastic cartridge is made of industrial-grade polypropylene material with outstanding chemical stability. It can effectively resist corrosion and erosion from various silicone sealants, building adhesives and harsh construction chemicals. It avoids swelling, cracking and material degradation during long-term storage and use, ensuring stable structural performance and extending service life for building sealing projects.

• Featuring high-clarity transparent body, this PP sealant cartridge enables real-time and clear observation of the residual volume and status of internal silicone sealant. It helps construction workers accurately grasp material consumption, avoid material waste caused by blind construction, and facilitate timely replacement and material replenishment to improve overall construction efficiency on site.

• Equipped with a precision inner sealing structure and tight adhesive fit design, the plastic cartridge achieves excellent airtight and leak-proof effects. It effectively isolates external air, dust and moisture, prevents the internal silicone sealant from drying out, solidifying or being contaminated, and maintains the original viscosity and performance of the sealant for long-term safe storage.

• Adopting the industry-standard 300ml capacity, this plastic cartridge perfectly matches most mainstream manual and pneumatic sealant guns for construction use. It features smooth inner wall and standardized nozzle structure to ensure uniform and smooth glue output without blockage. It is universally applicable to various building silicone sealants, gap fillers and waterproof adhesives.

• The integrated PP molding process endows the plastic cartridge with strong impact resistance and pressure resistance while keeping it lightweight. It can withstand frequent handling and slight collisions in complex construction environments without damage. Its portable size and sturdy structure adapt to various indoor and outdoor building sealing and caulking operations.
