Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt. Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry.

- How many raw materials go into tire composition?
- Over 200 raw materials go into tire composition. Researchers draw on this extensive array to combine tire components, each of which has a role to play, depending on the type of tire produced. The rubber compounds are made up of elastomers, renforcing fillers, plasticizers and others chemicals elements.
- What type of rubber is used in tire manufacturing?
- Rubber is the main raw material used in manufacturing tires, and both natural and synthetic rubber are used. Natural rubber is found as a milky liquid in the bark of the rubber tree, Hevea Brasiliensis. To produce the raw rubber used in tire manufacturing, the liquid latex is mixed with acids that cause the rubber to solidify.
- Which tyres are best for wet surfaces?
- Due to these properties, for example, more natural rubber is used in winter tyres than in summer tyres. A large part of the tyre - approximately a quarter - consists of fillers. For instance, carbon black and silica. They are used to strengthen and reinforce the rubber compound. Silica is actually better suited for wet surfaces than carbon black.
- What chemicals are used in tires?
- Sulfur and other chemicals are also used in tires. Specific chemicals, when mixed with rubber and then heated, produce specific tire characteristics such as high friction (but low mileage) for a racing tire or high mileage (but lower friction) for a passenger car tire.
- How is Tire Rubber made?
- Presses squeeze out excess water and form the rubber into sheets, and then the sheets are dried in tall smokehouses, pressed into enormous bales, and shipped to tire factories around the world. Synthetic rubber is produced from the polymers found in crude oil. The other primary ingredient in tire rubber is carbon black.
- Are rubber tyres vulcanised?
- Oil-based plasticizers (safe oils, so not carcinogenic) are used to modify the hardness and stiffness of tyres. Anti-degradants are chemical substances that protect tyres against the effects of sun, oxygen and ozone. Rubber is vulcanised by adding sulphur, which makes the compound more elastic.
