Poly Labs launched its proprietary Hydrophobic Energy Absorbing Polyurethane (PU) Foam formulas in 2020. It is changing the way helmet and impact protection systems are designed by uniquely combining hydrophobic properties with industry leading impact protection capabilities.
The reason it is considered hydrophobic foam, is because it exhibits low water absorption. This proves extremely useful in applications in which moisture (water, dew, humidity, sweat) is considered a factor. Additionally, this will help to avoid timely and costly secondary processes like bagging. Seen below are a few examples of our EA foam.
With very low rebound upon impaction our U-19 (105) energy absorbing (EA) foam can be molded between 0.15 and 0.20 g/cm³. The compression deflection can be varied to meet specific requirements.
Low-Density U-19 (105) Energy Absorbing Foam
Properties include a low-density energy absorbing foam ideal for combat and athletic impact protection padding. The properties of our U-19 (105) energy absorbing foam are as follows:
| Density | 0.13 to 0.25 g/cm³ |
| Hardness, Shore OO (3 sec) | 70 – 80 |
| Tensile Strength | 190 – 235 psi |
| Elongation | 70 – 95 % |
| Die C Tear | 4.5 – 6.0 pli |
