Polymer-rubber,Natural Rubbers,Types, Synthetic rubber .pptx

Rubbers are elastomers, these are polymers with an elastic property. This elasticity differentiates rubbers from plastics. Elastic means that the material can be stretched and, when released, returns to within at least 90% of its original dimensions and shape within a period of time, at room temperature.A polymer is a large molecule (macromolecule) composed of repeating, smaller units called monomers, forming a long chain.

1. POLYMER - RUBBER

2. Examples of Synthetic rubber The different types of synthetic rubber include  neoprene ,  Buna  rubbers , and  butyl rubbers , and they are usually developed with specific properties for specialist applications.  Styrene-butadiene rubber   and  butadiene rubber  (both  Buna  rubbers) are commonly used for tire manufacture.

3. Application Type of Rubber Application Natural  rubber Tires for commercial vehicles such as trucks, buses, and trailers Styrene-butadiene (SBR) and butadiene  rubber Tires for small trucks, private cars, motorbikes, and bicycles Butyl  rubber  (BR) Inner tubes

4. Examples of thermosetting plastics include  bakelite , urea-formaldehyde resins.
