Trade Name(s):
| ASTM D1418 Designation: | NR |
| Standard Colour: | Black |
Description:
This material is the vulcanized product of the juice of the Hevea tree (latex).
Key Use(s):
Seals in food and beverage applications. Most popular material for non-hydraulic sealing applications. Mainly used for dampeners due to its ability to absorb vibration.
Temperature Range:
| Standard Compound: | -50°C (-58°F) to 70°C (158°F) – Dry Heat Only |
| Hardness (Shore A): | 40 to 90 |
Features:
High tensile strength, high resilience, high abrasion and high tear resistance properties, with a good friction surface and excellent adhesion to metals. Until the invention of synthetic elastomers in the 1930’s, this material was the only polymer available for O-ring manufacture. Natural Rubber features good resistance to organic acids and alcohols, with moderate resistance to aldehydes.
Limitations:
Not widely used in sealing industry due to poor compression set performance and lack of resistance to many fluids.
