Dynamic Cushioning Curve for Rust-Shield®:

The following cushioning curve demonstrates that Rust-Shield® has equal or better cushioning properties when compared to 2.2 and 4 pcf commercial polyethylene foams. These are typical values and not product specification limits. The final package design should be tested to confirm it does not exceed the product’s fragility level.

**The data presented for this product is for unfabricated polyethylene foam product. While values are typical of this product they should not be construed as specification limits.
