Excellent Solvent

Works effectively as a solvent for oils, resins, waxes, and polymers, offering high solvency for a wide range of materials.

Low Volatility & High Stability

TEP performs well in high-temperature and high-pressure systems.

Non-toxic & Low Environmental Impact

TEP is considered low-toxicity and environmentally safer compared to other plasticizers.

Flexible Packaging Options

Available in 200KG drums and 1000KG IBC tanks to suit different volume requirements.

Applications

Flame Retardants

TEP is commonly used as a flame retardant in plastics, polymers, resins, and hydraulic oils, providing fire resistance in critical applications.

Plasticizer for PVC & Rubber

Enhances flexibility, softness, and impact resistance in PVC, cellulose, and synthetic rubbers.

Solvent for Coatings & Inks

TEP serves as an effective solvent for oils, waxes, dyes, and polymers in coatings and inks, improving the flowability and adhesion of formulations.
