Smooth Finish, Strong Foam Bonding with SCGC™ LLDPE Compound S15 Series

In cooler box manufacturing, the most challenging issue is delamination between the PE plastic layer and the PU Foam. This leads to bulging, deformation, and loss of thermal insulation efficiency, eventually resulting in high reject rates. 

Currently, manufacturers often rely on "PE Flake Spraying" or physical surface treatments to create a rough internal texture for mechanical bonding, a process that is time-consuming, adds extra steps, and is difficult to control for consistent quality.

Why S15 Series?

SCGC™ LLDPE Compound S15 Series is specifically engineered to solve this pain point. Our specialized compound formula focuses on enhancing "Chemical Adhesion Strength" between the PE surface and PU Foam.

Key Features of the S15 Series

• • Superior Adhesion, No More Delamination: Ensures a solid bond between the foam layer and the plastic surface. It delivers maximum performance when molded within the Optimum cook to Overcook range, and with a PU foam density of more than 0.036 g/cm³.
  • Eliminate PE Flake Spraying: 100% removal of the internal surface modification or PE flake spraying step, streamlining your entire production process.
  • Cost & Time Reduction: By eliminating the flake spraying step and significantly lowering the reject rate, overall production costs are reduced while production cycles become faster.
  • Excellent Surface Finish: Reduces common issues like White Stains or Mold Sticking, ensuring high-quality surface aesthetics for both the interior and exterior of the cooler box.

Recommended Industries

• Manufacturers of cooler boxes / ice boxes using PU foam as insulation
• Manufacturers of insulated containers for temperature-controlled transportation of goods and food
