Welcome to the Griswold blog!

Here you’ll find intriguing and often surprising insight about what we do at Griswold.

,
FlameSafe™ is our new line of open-cell sponge. Made from natural rubber, it is approved by UL for HBF flame resistance, the only rubber product in the world to receive this rating. These flame resistant materials are available in multiple firmness and thickness options, varying from 3mm to 1/2".
Griswold LLC manufacturers the majority of its Kushon® cellular rubber products using natural rubber as the polymer base. While so many of today’s foam materials are petroleum based, our natural rubber is sustainably harvested on plantations in Indonesia.  Unlike soy and corn based products, natural rubber does not divert food materials from either people or livestock.
Griswold Versatility of Foam
The versatility of foam is best demonstrated by the sheer number of markets and applications where it is used to solve design challenges.
Choosing the appropriate foam for military footwear involves many factors as different boots are designed for select areas of specialty, which can greatly differ between the Marines, Army, Navy, and Airforce.
