SpeedPak is a two-component urethane foam formulated to be applied without specialized application equipment. It is hand mixed and poured into you packing container. Within seconds SpeedPak expands 150 times its original liquid volume to form a flexible foam cradle around packaged parts. It provides vibration and impact resistance for packaged goods.

Speedpak is a fast, easy to use solution for protecting breakable items during shipping. After shipping the material is easily removed and discarded after use.

SpeedPak is two-component, lightweight (0.75 lb/ft3 density per cubic foot) urethane foam that is specifically formulated for pour-in-place packaging. When mixed SpeedPak quickly rises to form lightweight semi-flexible foam that exactly contours to the part being packaged and adheres to the cardboard box. This enhances resistance to damage caused by impact and crushing caused during shipping. SpeedPak is a hand mixed system that requires no special equipment.

Clean Up

Dispose of all empty SpeedPak component containers in accordance with local, state and federal regulations. Empty component containers can be rendered non-hazardous by rinsing the containers with a small amount of mixed material and allowing the solvents to evaporate. The containers will then contain non-hazardous cured urethane.

Storage and Shelf Life

SpeedPak is shipped from the factory in sealed containers. The containers should be stored in a cool, dry area that is protected from direct sunlight and moisture. Storage temperatures should not exceed 80° F. The shelf life of factory sealed containers stored under these conditions is six months. Containers that have been opened should be resealed immediately after the material has been removed in order to prevent solvent evaporation.


Shipping Class: Class 55 Non-hazardous
