1.Elastomers are materials that can be stretched and then return to their original shape.
2.Natural rubber has excellent tensile strength and good elasticity.
3.Natural rubber is resistant to oil and solvents.
4.Polybutadiene has a low glass transition temperature, giving good flexibility in cold weather.
5.Polybutadiene is more resistant to heat than other elastomers.
6.Neoprene is resistant to oil, chemicals and weathering, and is commonly used for wetsuits and seals.
7.Neoprene is cheaper than natural rubber.
8.Silicone has excellent heat resistance and is non-toxic and biocompatible.
9.Silicone is cheap compared to other elastomers and is highly sensitive to UV light.
10.Thermoplastic Elastomer (TPE) can be reprocessed by melting.
11.TPE has higher heat resistance than thermoset elastomers.
12.Natural rubber is biodegradable but can degrade with prolonged exposure to UV light and ozone.
