Does the plasticizer have fluorescence? Plasticizers used in PVC and other polymers generally do not spontaneously fluoresce, but certain types of plasticizers or their impurities may fluoresce under ultraviolet (UV) light. 1. Fluorescence properties of common plasticizers Common plasticizers (such as phthalates, adipates, citrates): Most traditional plasticizers (such as DOP, DINP, DOA, etc.) are nonfluorescent in themselves, and their chemical structures (such as benzene rings, fatty chains) g

How to distinguish which type of plasticizer? You can distinguish the type of plasticizer by looking at a few simple aspects: appearance, performance, application, and basic properties. First, chemical family is the most direct way. Common types include phthalates (DOP, DINP, DIDP), non-phthalates (DOTP, DPHP), aliphatic esters (DOA, DOS), polymeric plasticizers, and chlorinated plasticizers. Product name and MSDS usually tell you this. Second, check appearance and basic data. Most plasticizers
