3. Application & Performance Research

A. Rubber Industry (Reclaiming Agent)

Dipentene is a vital swelling agent and solvent in the rubber reclaiming process.

• Mechanism: It penetrates the vulcanized rubber matrix effectively due to its molecular structure similar to natural rubber (isoprene units).

• Performance: In waste tire recycling, adding Dipentene helps soften the rubber scrap at lower temperatures, preserving the polymer chain length better than harsh petroleum solvents.

B. Industrial Cleaning & Degreasing

A green alternative to toxic chlorinated solvents or Toluene.

• Grease Removal: Excellent for removing heavy oils, carbon deposits, and bitumen from machinery.

• Compatibility: Non-corrosive to most metals (steel, aluminum).

• Example Usage: Used in formulation of hand cleaners and electronic circuit board cleaners.

C. Paints, Inks & Coatings

• Anti-Skinning Agent: Prevents the formation of surface skin in oil-based paints during storage.

• Flow Agent: Improves wetting and leveling properties in alkyd resin enamels.

4. Packaging & Storage

• Galvanized Iron Drum: 175 kg net weight per drum.

• ISO Tank: Approx 20 MT per tank (Bulk liquid).

• Storage Conditions: Store in a cool (below 30°C), dry, well-ventilated area. Keep container tightly closed. Avoid direct sunlight. Dipentene is flammable; keep away from sparks or open flames.

5. Why Choose Our Dipentene?

• Stable Supply Chain: Sourced directly from large-scale camphor production lines (as a co-product) or pine oil fractionation, ensuring consistent monthly volume.

• Custom Blending: We can adjust the specific gravity and terpene composition slightly to match specific solvent formulations if required.
