Chemical Properties and SafetyStyrene possesses a molecular formula of C8H8 and a molecular weight of 104.15 g/mol. It is stable when properly stored, but as a flammable liquid (Hazard Class 3), it requires precautions such as storing in tightly closed containers away from heat and ignition sources. With a flash point of 32C and an autoignition temperature of 490C, safe handling is critical.
Applications and Key BenefitsStyrene serves as an important raw material for producing polystyrene, ABS, SBR, and diverse resins. Its neutral pH and high purity make it suitable for creating high-quality polymers that are used in the plastics, rubber, and resin industries. Manufacturers value styrene for consistently delivering reliable performance in numerous industrial synthesis processes.
Packaging and LogisticsSupplied in 200 kg drums or ISO tanks, styrene is easily transported under UN No. 1992 guidelines. Shelf life is six months when stored properly, ensuring product integrity. The minimum order quantity of one drum makes it accessible for various businesses, including distributors, manufacturers, importers, and retailers throughout India.
FAQs of Styrene:
