Suministramos a más de 4500 clientes en más de 80 países
Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 1999 · Certificado de Análisis (CoA) con cada lote
Polystyrene is a synthetic aromatic polymer made from the monomer styrene, widely used in packaging, insulation, and disposable cutlery due to its lightweight, rigid, and insulating properties. This high-molecular-weight variant (M.W. ~100,000) is particularly valued for its durability and clarity in applications like CD cases, laboratory equipment, and protective foam. While its molecular formula is often misstated as C₈H₁₅N₃ (incorrect for polystyrene), the accurate formula is (C₈H₈)ₙ. Key details: CAS 9003-53-6, stable at ambient storage, no signal word required. Molekula supplies polystyrene from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Preguntas frecuentes
What is polystyrene used for?
Polystyrene is commonly used in packaging materials (e.g., foam cups, packaging peanuts), disposable cutlery, insulation, and as a substrate for tissue culture in labs.
What is the correct chemical formula and molecular weight of polystyrene?
The provided formula **C₈H₁₅N₃** and MW **153.2248** appear incorrect for polystyrene; the correct formula is **(C₈H₈)ₙ** (repeating styrene unit), with MW ~100,000 for this grade.
How should polystyrene be stored?
Store polystyrene at ambient conditions, away from direct sunlight and moisture, in a clean, dry environment.
What grades of polystyrene does Molekula supply?
Molekula supplies **general-purpose polystyrene** (GPPS) and **high-impact polystyrene** (HIPS) in pellet or bead form; confirm your specific application for exact grade recommendations.
Can Molekula supply polystyrene in bulk quantities?
Yes, polystyrene is available in bulk (e.g., 25kg bags, 500kg drums, or larger custom quantities) for industrial and research applications.
What documentation comes with a polystyrene order?
Each order includes a **Certificate of Analysis (CoA)**, **Material Safety Data Sheet (MSDS)**, and **batch-specific documentation** for traceability.
