structure design, performance simulation and plasticizing,plasticizer is an important assistant in the production process of polyvinyl chloride (pvc), which can effectively improve the plasticity of pvc. however, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. in this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four different diols.

plasticizers are used to make pvc flexible so it can be used as a geomembrane for containment purposes. plasticizers can migrate from pvc geomembranes over time because of contact with air, liquid, and an absorbent solid material. plasticizer migration can reduce the flexibility of pvc geomembranes resulting in brittle behaviour. this paper.

a brief evaluation of antioxidants, antistatics price,therefore, primary plasticizers can typically be used as the only component in the plasticizer formulation, while secondary plasticizers are never applied alone. however, the division of plasticizers is typically based on their chemical structures, phthalates and non-phthalates, and are described in more detail below [ 12 , 13 ].
general, plasticizers are added into pvc to improve the thermal, mechanical and flame-retardant properties [2]. nowadays, there are more than 500 kinds of plasticizers in the market. among them, phthalate plasticizers dominate the main commercial plasticizers [3]. these phthalate plasticizers are derived from petroleum resources.

china dbs plasticizer wholesale select 2024 high quality dbs plasticizer products in best price from certified chinese plastic plasticizer manufacturers, pvc plasticizer suppliers, wholesalers and factory,It can be used for cellophane, coatings, adhesives and rubber products for food packaging.
widespread occurrence of phthalate and non-phthalate,among all plasticizers analyzed, dbs was found at the highest mean concentration, 3350 ± 2130 ng/g. this is the first study to report adipates and dbs in facemasks. due to increasing concern over endocrine-disrupting properties of phthalates, substitute plasticizers such as dbs are becoming more widely used in consumer products.
- Are DBS and DHS a good plasticizer for PVC?
- Where data was available, the results from this study are in good agreement with the experiment; we conclude that DBS and DHS are most promising green plasticizers for PVC, since they have properties comparable to DEHP but not the environmental and toxicity concerns.
- Are plasticizers environmentally friendly?
- Four environmentally friendly plasticizer samples were obtained; their chemical structures and compositions were confirmed by gas chromatography (GC) and infrared spectroscopy (FT–IR) analyses, and their physicochemical properties and thermal stability (TGA analysis) were investigated.
- What materials are used to make plasticizers?
- The plasticizers used in this study were synthesized from renewable raw materials using succinic acid, oleic acid, and propylene glycol.
- Can bio-based plasticizers compete with DEHP in PVC?
- Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS). To examine whether that these bio-based plasticizers can compete with DEHP, we need to compare their tensile, mechanical, and difusional properties.
- Are bio-based succinate esters effective PVC plasticizers?
- They investigated a series of bio-based succinate esters: diethyl- (DES), dibutyl- (DBS), dihexyl- (DHS), diethylhexyl- (DEHS), didecyl- (DDS), and didodecylsuccinate (DDoDS) as effective PVC plasticizers.
- Can plasticizers replace petroleum-based plasticizer in PVC applications?
- Compared to DINP and DEHP, the migration was as much as 70% lower for each plasticizer concentration. Thus, due to their good compatibility, efficiency and thermal properties, the plasticizers synthesized in this research have the potential to replace petroleum-based plasticizers in PVC applications.
