Natural Rubber (NR) has the widest range of hardnesses, very strong and extremely resilient. Applications include those requiring strength and resistance to abrasion, sealing and shock absorption. Typical applications: - Components which are protected from constant air changes – i.e. inside machinery – and which do not come into contact with any oil or oil based fluids
- Applications requiring strength and resistance to abrasion
- Sealing and shock absorption
Advantages: - Widest range of hardnesses
- Very strong (naturally self-reinforcing) and extremely resilient
- Good compression set
- Good resistance to inorganic chemicals
- Very good deformation capacity
- Good flex fatigue resistance
- Very good abrasion resistance
Disadvantages: - Lack of resistance to oil and organic fluids
- Relatively low maximum temperatures (75°C continuous, 100°C intermittent)
- Poor ozone resistance, with tendency to perish in open air (can be improved to some extentby careful compounding).
