Frequently Asked Questions
DINP is mainly used in flexible PVC and soft polymer products, including electrical wires and cables, automotive interiors, PVC flooring and leather, artificial leather, waterproof membranes, flexible films, plastic hoses, seals, wallpaper, footwear materials, and edge banding. It is suitable for medium- and high-end flexible plastic applications requiring flexibility, processing stability, and migration resistance.
Compared with traditional DOP, DINP typically offers lower volatility, stronger migration and extraction resistance, better heat, weathering, aging resistance and electrical insulation performance. It also provides improved low-temperature flexibility and lower processing fumes, making it suitable for flexible PVC products requiring longer service life and greater stability.
DINP is suitable for standard flexible PVC products, while DPHP has a higher molecular weight, lower volatility, and better heat and aging resistance, making it more suitable for demanding applications such as wire and cable and outdoor PVC.
DINP offers good resistance to ultraviolet radiation, oxidation, acids, and alkalis. It is suitable for long-term outdoor applications such as PVC films, advertising fabrics, and building materials, helping reduce the risk of yellowing, cracking, and embrittlement.
Yes. DINP has strong compatibility and can be blended with DOTP, ESBO, TOTM, DIDP, DPHP and other plasticizers to balance cost and performance while optimizing formulations for heat resistance, cold resistance and weather resistance.
Dioctyl phthalate (DOP) is a general-purpose primary plasticizer with high plasticizing efficiency, good compatibility, and excellent resistance to high and low temperatures, low volatility, and electrical insulation stability. It is widely applicable to PVC films, artificial leather, wires and cables, and various soft plastic products, effectively optimizing processing flow and imparting excellent flexibility and durability to finished products. It is the preferred plasticizer solution for those seeking high cost-effectiveness and high reliability.
DPHP is a phthalate plasticizer primarily used in flexible PVC, rubber, and other polymer materials. With its low volatility, low migration, good heat resistance, and stable processing performance, DPHP enhances the flexibility, durability, and long-term performance of materials, and is widely used in wires and cables, PVC flooring, artificial leather, automotive interiors, and industrial products.
DOTP is an environmentally friendly, non-phthalic plasticizer with good PVC compatibility, excellent flexibility, low volatility, and good electrical insulation properties. DOTP is widely used in PVC wires and cables, films, artificial leather, hoses, and other flexible PVC products, suitable for applications requiring environmental protection, safety, and long-term stability.
DEHCH is a non-phthalic acid environmentally friendly plasticizer with good PVC compatibility, low volatility, low migration, and excellent durability. DEHCH can impart good flexibility, processing performance, and long-term stability to PVC materials, making it suitable for applications with high requirements for environmental protection, safety, and durability, such as medical supplies, automotive interiors, wires and cables, and high-end flexible PVC products.
TOTM features low volatility, low migration, and excellent heat stability, effectively improving the service life and performance retention of flexible PVC materials in high-temperature environments. TOTM is widely used in high-temperature resistant wires and cables, automotive interior materials, industrial hoses, and other demanding flexible PVC products.
