Didecyl phthalate CAS 26761-40-0 DIDP

Diisodecyl phthalate (DIDP) is a variety of phthalates (i.e., phthalates). It is liquid at room temperature and is often used in industry as a plasticizer (plasticizer) for resins or plastics, especially for products with high heat resistance or insulation requirements, such as UL 90-degree Celsius grade cables. DIDP is a type of phthalate that is not subject to the testing standards of the European Union. Due to the fact that DIDP has a longer carbon chain, a larger relative molecular mass, a higher flash point, a higher boiling point, and relatively lower toxicity among common phthalates with industrial value, it is also commonly referred to as a type of environmentally friendly plasticizer
