It is a low sulfur, low aromatic (usually less than 0.5% aromatic content), non-toxic, and odorless hydrogenated refined petroleum product. It has a high content of saturated hydrocarbons (>99%), strong solubility, and controllable volatility. It mainly includes D-series environmentally friendly solvent oils (such as D30, D40, D80, D95) and high-purity isoparaffins, widely replacing traditional harmful solvents for fine industrial cleaning, coating dilution, daily chemical aerosols, and textile auxiliaries. Core characteristics of low toxicity and environmental protection: Strictly limit harmful components such as benzene and sulfur, with low harm to human health. Superior physical performance: no odor (or low odor), adjustable flash point, meeting different safety level requirements. Stable performance: Good oxidation stability, narrow fraction, uniform volatilization rate. Common types and uses: D series environmentally friendly solvent oil (D30/D40/D60/D80): a typical hydrocarbon cleaning agent, suitable for metal cleaning, dry cleaning agents, and diluents. Isoalkane environmentally friendly solvent: high-purity, used for personal care products and aerosol insecticides. Application areas: Metal processing and cleaning: used for metal rust prevention oil, aluminum rolling oil, and electric discharge cutting oil. Coatings and inks: odorless diluents for high-end paints and printing inks. Fine chemicals: solvents for liquid mosquito coils and aerosol insecticides. Other: Textile printing and dyeing auxiliaries, PVC disposable glove viscosity reducer
