Natural Rubber (NR)
Natural Rubber (NR) is a Poly-isoprene, its derived from latex liquid extracted from rubber trees.
Features:
– Natural Rubber has good resilience, abrasion and surface friction properties and excellent compression set. It has low hysteresis and rolling resistance with high fatigue resistance and remains flexible at low temperatures.
– Natural Rubber also has very good dynamic mechanical properties and is therefore used in tires, rubber springs and vibrations mounts.
Application:
- Rubber gaskets
- Rubber seals
- Hose and tubing
- Vibration isolators
- Shock mounts
- Electrical components
