Superior DOTP (Dioctyl Terephthalate) is a premium-grade, non-phthalate plasticizer specifically engineered for high-performance PVC applications. With its exceptional electrical insulation properties (volume resistance ≥2×10¹² Ω·cm) and outstanding low-temperature flexibility, it is the preferred choice for PVC wire and cable insulation, medical gloves, and food-contact applications. Unlike traditional DOP, DOTP offers superior thermal stability, lower volatility, and excellent resistance to migration, making it an environmentally friendly alternative that meets stringent international regulations including REACH and RoHS. Our Superior DOTP achieves ≥98% purity with flash point ≥210°C, ensuring consistent processing performance and long-term product durability.

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.
