RamFoam EZFloat 2.0

Two-Component, Closed-Cell Spray Polyurethane Foam for Marine Flotation

Overview

RamFoam EZFloat 2.0 LD is a two-component, closed-cell spray polyurethane foam (SPF) system. It is designed for use as a flotation fill in marine applications such as boats, docks, and personal watercraft. EZFloat 2.0 LD provides buoyancy, structural support, and resistance to water absorption in demanding marine environments.

Key Features

Marine Flotation

Specifically designed as a flotation fill for boats, docks, and personal watercraft, providing reliable buoyancy in demanding marine environments.

Closed-Cell Structure

Closed-cell chemistry delivers greater than 95% closed cell content, minimizing water absorption and maintaining long-term buoyancy performance.

Low Water Absorption

Water absorption by volume of only 0.49% (ASTM D2842), ensuring the foam retains its flotation properties even after prolonged water exposure.

Structural Support

Compressive strength of 40 psi parallel and 28 psi perpendicular (ASTM D1621), with shear strength of 37 psi, providing structural reinforcement within marine hulls and cavities.

Fast Cream and Rise

Cream time of 35–40 seconds and rise time of 200–250 seconds allow controlled pour-in-place application with predictable expansion in enclosed cavities.

UL 94 HBF Flame Classification

Rated UL 94 HBF per QAI Test Report No. TJ5347, meeting flame spread requirements for marine and enclosed-space applications.

Typical Applications

  • Boat flotation fill
  • Dock and marina flotation
  • Personal watercraft flotation
  • Marine hull cavity fill
  • Buoyancy and structural support in marine applications
