COA ships with every batch; regulatory items are issued by SGS as a third party.
Qualified DOTP offers the same non-phthalate chemistry as our Superior grade at a more accessible price point for general-purpose PVC applications. With volume resistance ≥2×10¹² Ω·cm and flash point ≥210°C, it delivers reliable performance for PVC film, synthetic leather, footwear materials, and household gloves. The Qualified grade maintains excellent compatibility with standard PVC formulations while providing good thermal stability and low volatility. It serves as an ideal drop-in replacement for DOP in cost-sensitive applications where regulatory compliance and environmental safety are still required.

One batch, one specification — pick your downstream process for grade advice.
Cable insulation compounds need a plasticizer that holds volume resistivity, keeps volatility low and stays stable through heat ageing. We match the grade to the processing window and to the insulation class the cable has to hold.
Film and sheet need clarity, flexibility and weather resistance, and the plasticizer has to stay in the film so the sheet keeps its dimensions. Film thickness and the end use fix which grade fits, and both are agreed before the first drum is packed.
Coated fabric for furniture upholstery and automotive interiors needs a soft hand feel plus resistance to abrasion and flex fatigue. The plasticizer has to stay in the coating instead of migrating into the backcloth, so the hand feel holds over time.
Soles and upper materials need abrasion resistance and flex crack resistance, and thin parts lose softness fastest once plasticizer migrates. Target hardness and the buyer's flex test set the grade, and the sample is moulded to both.
Glove film has to stay pinhole-free at low thickness, so the plastisol needs a plasticizer with low volatility and a viscosity that holds through the dip. Consistent viscosity across batches is what holds the film thickness inside tolerance.
Household gloves are dipped from PVC plastisol, and the plasticizer sets both the hand feel and how much softener comes to the surface. We match the grade to the target hand feel and to the filler loading on the line.

Shandong's market regulation and development-and-reform authorities put Jining Wansheng Environmental's waste-PET-to-DOTP recycling model into the 2026 provincial standardization pilot program (green low-carbon field) - item 6 of 10, and the only waste-plastics entry. The pilot runs 2027-2028 and must deliver a standard system for PET recycling, industry-scale standard proposals, and a replicable working model.
