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.
For disposable medical examination gloves, Superior DOTP at typically 55-70 phr delivers the soft, transparent, low-pinhole film that AQL inspection expects. Household and dishwashing gloves run lighter at 45-65 phr, and industrial or chemical-protective gloves go up to around 70 phr with chemical-resistant stabilizers for EN 374 performance. When converting a line from DEHP or DINP, start from the current loading and add 2-5 phr to compensate for DOTP's slightly lower plasticizing efficiency, then confirm hardness, tensile strength, elongation and pinhole rate in a lab trial before switching production.
Disposable vinyl exam gloves sit at the soft end of the range — typically 55-70 phr DOTP in the plastisol. Color ≤150 APHA keeps the transparent film visually clean, and acidity ≤0.035% with water ≤0.1% protects stabilizer and pinhole rates during oven fusion.

Household and dishwashing gloves run at 45-65 phr; industrial and chemical-protective gloves go up to around 70 phr, paired with chemical-resistant stabilizers for EN 374 performance. Low migration keeps the glove surface clean in long-term skin contact.

Our Superior-grade DOTP goes mainly to disposable PVC medical examination gloves at home and abroad. What DOTP does in glove plastisol, why DEHP is out, which specification a glove plant should audit, and how we price about 10% below comparable domestic supply.

Read MoreNo. It is the same product — the same batches, the same specification (CAS 6422-86-2). This page recommends our Superior DOTP for PVC glove production and gathers the application data glove manufacturers ask for. There is no separate formulation, and no separate TDS or COA.
DOTP is a terephthalate ester, not an ortho-phthalate. It is not restricted under EU REACH Annex XVII entry 51 (which caps DEHP, DBP, BBP and DIBP at 0.1% in consumer articles such as gloves), is not classified as a CMR substance, and is not listed under California Proposition 65. Migration is verified per batch: ask for the ISO 177 or HG/T 4454 report (mass change) that matches the shipped lot rather than relying on generic figures.
Across the 45-70 phr range depending on glove type and target softness: household and dishwashing gloves 45-65 phr, disposable medical examination gloves 55-70 phr, industrial and chemical-protective gloves around 60-70 phr. When switching from DEHP or DINP, start at your current loading and confirm hardness, tensile strength, elongation and pinhole rate in a lab trial before full production.
