Understanding Cartridge Density Options

High-Density Polyethylene (HDPE) Cartridges

• Enhanced Rigidity: Superior structural integrity for demanding applications
• Chemical Resistance: Excellent barrier properties against aggressive materials
• Durability: Maintains shape under pressure and temperature variations
• Ideal For: High-viscosity sealants, structural adhesives, and heavy-duty applications

Low-Density Polyethylene (LDPE) Cartridges

• Flexibility: Greater pliability for easier material dispensing
• Smooth Flow: Optimal for lower-viscosity materials
• Gentle Pressure: Reduced force required for dispensing
• Ideal For: Standard sealants, coatings, and general-purpose applications
