| 1. | This provides more water and impact resistance, hardness, rigidity and tensile strength.
|
| 2. | This molecular-oriented bi-axial high performance version combines high strength with extra impact resistance.
|
| 3. | Poly carbonates have one of the highest impact resistance values.
|
| 4. | Manufacturers use additives to improve impact resistance, and to prevent ultraviolet damage and color fading.
|
| 5. | However in some cases a heavier type was used if additional impact resistance was needed.
|
| 6. | Significantly higher impact resistances are realized when geotextiles are placed above or below the geomembrane.
|
| 7. | :I'd go with coated polycarbonate, to get both polycarbonate's impact resistance and the coating's scratch resistance.
|
| 8. | "' Izod impact testing "'is an ASTM standard method of determining the impact resistance of materials.
|
| 9. | _improvements in the impact resistance of the nose-cone.
|
| 10. | Thicker geomembranes also display higher impact resistances.
