Industrial-Grade Styrene: Essential Resin Manufacturing Ingredient

short description:

Molecular forula: C₈H₈

Styrene is a key petrochemical product and versatile polymer monomer widely used in global industries. This colorless, transparent oily liquid with a characteristic aromatic odor is insoluble in water but miscible with most organic solvents, making styrene an indispensable raw material for plastic synthesis. As a core intermediate, styrene is primarily used to produce polystyrene, ABS resin, and synthetic rubber, driving innovations in packaging, construction, and automotive sectors. Notably, styrene is prone to polymerization at room temperature, so inhibitors like hydroquinone are essential for safe storage and transportation. With its stable chemical properties and broad applicability, styrene remains a cornerstone of modern polymer manufacturing, supporting diverse industrial chains worldwide.

Styrene (CAS 100-42-5) is a pivotal petrochemical monomer and core building block for modern polymer manufacturing, celebrated for its exceptional polymerization activity and material-compatibility. As a versatile feedstock, it serves as the foundational ingredient for synthesizing high-performance polymers, enabling the production of durable, functional materials that meet stringent industrial requirements.

Widely applied across global sectors, it is primarily used to manufacture polystyrene (PS), ABS resin, styrene-butadiene rubber (SBR), and unsaturated polyester resins (UPR), which further support industries such as packaging, automotive interior components, construction insulation, electronic device housings, and medical device substrates.

Our styrene product offers multiple grade options (industrial, polymerization, and high-purity) to align with diverse production needs, featuring strict quality control to ensure low impurity content and stable monomer reactivity. We guarantee reliable bulk supply, complete hazardous goods documentation (including MSDS, UN certification), and tailored logistics solutions for flammable liquid transportation. Additionally, our professional technical team provides personalized support—such as inhibitor selection and storage guidance—to optimize your production efficiency and safety.
