Benzine is a colorless flammable liquid derived from crude petroleum by fractional distillation, a mixture of hydrocarbons used in various cleaners. Benzene is a single compound from coal tar used to make benzene series chemicals.
Cold Rubber in Name Only Produced at Low Temperature
Cold rubber is made near freezing, not heat, yielding uniform molecules and long wear. It is used in tires and footwear, reduces heat, and promises 75,000 mile tires. production has spread across several companies with government-supported MDN ferricyanide polymerization helping scale up.
