Product Overview

Two liquids, one custom-fit cushion

Part A and Part B are stored separately and only react when they meet in the mixing head of a foam-in-place machine. The mixture expands to fill the space around your product and cures into a lightweight, shock-absorbing foam shaped exactly to it — no pre-cut inserts or bulky stock needed.

Fast Expansion

Foams and fills the cavity in seconds.

Anti-Shock Cushion

Absorbs impact and vibration in transit.

Two Drum Sizes

Large or small drums to suit your volume.
