In modern industrial compounding, regulatory environments are rapidly evolving, forcing manufacturers to move away from traditional ortho-phthalate chemistries without losing technical polymer performance. Di(2-ethylhexyl) cyclohexane-1,2-dicarboxylate (universally recognized in advanced global sourcing as DEHCH) represents a premium, non-phthalate primary plasticizer designed specifically to solve this dilemma. Chemically categorized under the cyclohexane family (CAS No. 84-71-9), DEHCH is a water-white, low-volatility, clear liquid featuring a fully saturated ring structure. This unique ring geometry grants it exceptional weather resistance and an outstanding EHS profile, establishing DEHCH as an innovative cornerstone alternative for toys, medical devices, food-contact foils, and technical elastomer processing.

Why Choose Our DEHCH Plasticizer?
- ✓ Elite Toxicological Safety Profile: Fully structural alternative to ortho-phthalate ring configurations, matching stringent modern safety benchmarks such as EU REACH, US CA Prop 65, and worldwide food-contact standards.
- ✓ Outstanding Extraction Resistance: Its saturated alkyl-cyclohexane network delivers exceptionally low volatility and high resistance to water leaching, grease washout, and outdoor migration loops.
- ✓ Excellent Plasticizing Efficiency: Provides strong, clean solvating actions with polar elastomers and vinyl compounds, lowering processing viscosities and optimizing elongation properties.
Primary Applications
Phthalate-free DEHCH is widely utilized across polyvinyl chloride (PVC) sheets, Nitrile Rubber (NBR), Polyurethane (PU), and high-compliance consumer polymer recipes:
Medical Devices & Apparel
An elite non-toxic standard for high-purity medical tubing arrays, oxygen masks, fluid bags, surgical drapes, and clinical laboratory consumables.
Sensitive Consumer Products & Toys
Extensively formulated into children’s soft toys, pacifiers, clear food-contact wrap foils, water drinking straws, and eco-conscious household profiles.
Nitrile (NBR) Rubber Modification
Formulated into premium polar synthetic elastomers to decrease compounding mill friction, lower Mooney viscosity values, and enhance sub-zero climate flex characteristics.
⚠ Storage & Handling Guidelines
Maintaining proper warehouse environment control parameters is vital to protect the high active purity, low acid value, and excellent water-white clarity of Di(2-ethylhexyl) cyclohexane-1,2-dicarboxylate (DEHCH). Although it features outstanding saturated ring stability and a high flash point, protecting containers from humidity ingress ensures maximum dielectric and insulation integrity.
- • Warehouse Climate Control: Store all liquid drums, IBC totes, or bulk storage vessels inside a thoroughly cool, dry, and well-ventilated dedicated warehouse footprint. Keep storage rows completely isolated from direct sunlight, heating lines, steam grids, or open flames.
- • Airtight Sealing Management: Ensure all container bungs, container valves, and caps are tightly resealed immediately after any sampling or dispensing operations. Keeping containers hermetically sealed limits moisture absorption and keeps the compound acid values within premium boundaries.
- • Shelf Life & Rotation Strategy: Under clean, temperature-controlled, and sealed environment parameters, our premium DEHCH plasticizer carries a certified shelf life of 24 months from the date of manufacture. Adhering to a strict First-In, First-Out (FIFO) material rotation system is recommended.
