Description

Phenylethene CAS NO 100-42-5 is a fundamental monomer in the petrochemical industry, widely recognized as styrene. This versatile aromatic hydrocarbon is a critical building block for a vast array of polymers and copolymers, prized for its excellent processing characteristics and the clarity and rigidity it imparts to finished products. It is an essential raw material for manufacturers in the plastics, rubber, and resin sectors seeking to produce high-performance materials for diverse applications.

Application

• Polystyrene (PS) Production: The primary use, forming crystal, high-impact, and expandable polystyrene for packaging, disposable food containers, and insulation.
• Acrylonitrile Butadiene Styrene (ABS) Resins: A key component in engineering plastics used for automotive parts, consumer electronics housings, and LEGO® bricks.
• Styrene-Butadiene Rubber (SBR) & Latex: Used in tire manufacturing, footwear, and as a binder in carpet backing and paper coatings.
• Unsaturated Polyester Resins (UPR): Serves as a cross-linking agent for fiberglass-reinforced plastics in marine, automotive, and construction applications.
• Styrene-Acrylonitrile (SAN) Copolymers: Used to produce transparent, rigid materials for kitchenware, appliance components, and medical devices.
• Chemical Synthesis: Acts as a precursor in the manufacture of various fine chemicals and specialty polymers.

Quality Control

Our Phenylethene (Styrene) is produced and handled under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, inhibitor content, and physical properties. Certificates of Analysis (COA) detailing assay, impurity profiles, and other critical parameters are provided to guarantee consistency and compliance with your process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and maintain temperatures below 25°C to prevent polymerization and ensure product stability. Keep away from strong oxidizing agents.
