How do I bond aluminum skins to a foam core? Does the glue attack the foam?
This is a common failure point called Solvent Attack. Many[…]
Can foam cores be recycled? What is the industry doing about sustainability?
Yes, but it depends on the chemistry.
What is the best foam core for high-temperature applications (e.g., composite curing in an autoclave)?
Standard EPS melts at 80°C and PVC softens around[…]
How do Fire, Smoke, and Toxicity (FST) standards limit my choice of foam core?
This is the #1 barrier to entry for foam[…]
What does “Density” (kg/m³ or lb/ft³) mean for foam core performance?
Density is the primary determinant of both Price and Strength.
Can I use regular construction foam (PU spray foam) as a structural core for a boat?
Absolutely not. Hardware store spray foam is typically Open-Cell and low-density (0.5-1.5[…]
What is the most cost-effective foam core material for high-volume production?
For non-structural, high-volume applications (like packaging or disposable formwork), EPS[…]
How do I calculate the weight savings of using a Foam Core Sandwich Panel versus a solid steel plate?
The rule of thumb for Flexural Stiffness is cubic. To double[…]
What is the fundamental difference between Closed-Cell and Open-Cell Foam Cores?
The distinction is critical for any application involving moisture[…]
