Description

Norseal PF47 Series features enhanced micro-cellular polyurethane foam solutions, specifically developed for efficient functioning of batteries in a pack.

Uniformity of cell temperature and cell pressure is needed for a long battery life. The compressed foam between cells creates uniform pressure over the cell surface. The thermal insulation properties of the foam also help to maintain the cell face temperature. These properties and resulting function of the foam are very consistent over time and over a range of environmental conditions, ensuring a long life for the pack.

A2 = Adhesive on Both Sides

Benefits

  • Helps to maintain the li-ion pouch cell face temperature and pressure.
  • Very consistent over time and over a range of environmental conditions, ensuring a long life for the pack.

Features

  • High resiliency performance over complete compression range
  • Soft foam that provides consistent deflection force over wide compression resulting in a flat CFD curve & uniform pressure to battery cells
  • Ideal for Intricate area gasketing

Recommended Uses

  • Compression/tolerance pads in lithium-ion pouch and prismatic cell packs
  • Intricate area gasketing
