Engineered specifically for outdoor and high-UV environments, our 300ml Black HDPE Plastic Cartridge provides superior protection for silicone sealants, RTV adhesives, and thermal gap fillers prone to UV degradation. Constructed from high-density polyethylene (HDPE) infused with carbon black pigment, this cartridge blocks 99% of harmful UV rays to prevent material curing, discoloration, or performance loss during storage. The airtight plunger system and threaded nozzle interface ensure leak-free dispensing, even in extreme weather conditions—making it a trusted choice for construction, automotive, and marine applications where silicone integrity is critical.

UV-Stabilized Construction: Carbon black pigment integration creates a barrier against UVA/UVB rays, preventing silicone material embrittlement and maintaining flexibility after 1,000+ hours of outdoor exposure.
Extended Chemical Resistance: Compatible with all silicone formulations, acrylics, and solvent-based compounds, withstanding pH levels from 2–12 without material degradation.
Efficient Material Evacuation: Precision-molded internal ribbing reduces friction between plunger and cartridge walls, enabling 98% material usage to minimize waste and maximize cost efficiency.
Secure Storage Features: Tamper-evident breakable neck seal confirms product freshness, while an optional re-sealable nozzle cap allows partial use with prolonged storage between applications.
Customizable Dispensing Options: Available with 3mm, 5mm, or 8mm precision orifice nozzles to control bead size, with blunt-tip variants for specialty applications like electronics potting.
Exterior Construction: Sealing window frames, roofing joints, and expansion gaps in high-sunlight regions with UV-cured silicone sealants.
Outdoor Electronics: Packaging thermal interface materials (TIMs) and conformal coatings for solar panels, outdoor lighting, and communication equipment.
Automotive Underhood: Storing high-temperature engine sealants and gasket makers that require UV protection during shelf storage.
Marine Maintenance: Waterproofing boat decks, hull seams, and dock fittings with saltwater-resistant silicone formulations exposed to intense sunlight.
Q: Is this cartridge suitable for food-grade silicone applications?
A: Yes, its HDPE construction meets FDA 21 CFR 177.1520 standards for indirect food contact, making it safe for packaging silicones used in food processing equipment and kitchen fixtures.
Q: What is the shelf life of filled silicone cartridges?
A: When stored in cool, dark conditions (below 25°C), filled cartridges maintain silicone performance for 24 months—twice the shelf life of clear cartridges in UV-exposed environments.
Q: Can the nozzle be replaced for different application needs?
A: Yes, the standard 1/4" NPT threaded nozzle is easily replaceable with specialty tips, including flexible extensions for hard-to-reach areas and multi-orifice designs for wide-seam sealing.
