High-Purity Meta-Xylene Chemical Feedstock

short description:

Xylene (commonly called dimethylbenzene) is a pivotal aromatic hydrocarbon in industrial chemistry. Comprising three isomers (o-, m-, and p-xylene), commercial Xylene is typically a stable mixture, appearing as a colorless, transparent liquid with a distinct aromatic odor.

This versatile Xylene functions first as a high-performance solvent: it dissolves resins, rubbers, and dyes for coatings, printing inks, and electronic cleaning. Beyond solvency, Xylene serves as a critical feedstock—processed into p-xylene (a precursor for PET plastics) and fine chemicals for textiles and packaging.

Notably, Xylene is flammable, requiring proper ventilation during handling. Despite such precautions, Xylene remains a foundational material that underpins modern chemical and manufacturing supply chains.

Xylene (CAS 1330-20-7) is a pivotal petrochemical solvent and chemical feedstock, consisting of three isomers (o-, m-, and p-xylene) that form a stable, colorless liquid with a distinct aromatic odor. Celebrated for its excellent solvency power and material compatibility, it acts as a versatile foundational material that meets stringent industrial formulation and synthesis requirements.

Widely utilized across global sectors, it serves primarily as a high-performance solvent for coatings, printing inks, and electronic component cleaning; it also acts as a key feedstock for synthesizing p-phthalic acid (a core precursor for PET plastics) and fine chemicals. These derivatives further support industries including packaging, automotive coating manufacturing, electronic device production, textile processing, and architectural decoration.

Our xylene product offers multiple grade options (industrial-grade and high-purity grade) to align with diverse production needs, featuring strict quality control to ensure low impurity content and consistent solvency/stability. We guarantee reliable bulk supply, complete hazardous goods documentation (including MSDS and UN certification), and tailored logistics solutions for flammable liquid transportation. Additionally, our professional technical team provides personalized support—such as storage condition guidance and solvent compatibility recommendations—to optimize your production efficiency and operational safety.
