Synthesis and properties of castor oil based plasticizers
Synthesis of acetylated castor oil (ACO) Castor oil (93.4 g) and acetic anhydride (27.5 g) were added to a 500 mL four-necked flask, and were stirred at 140 °C for 2 h. Then the reaction mixture was washed to pH = 7 with sodium carbonate solution and distilled water. Then the water was removed by vacuum distillation.
Synthesis of novel plasticizer ester end-capped oligomeric
The plasticizing performance of EOLs in PVC was tested and compared with those of commercial environmental plasticizers acetyl tributyl citrate (ATBC) and di-2-ethylhexyl terephthalate (DOTP). According to the results of tensile tests, the elongation at break of PVC plasticized by 50 phr EOLs reached 725.5%, indicating its superior mechanical
EcoFriendly Plasticizers IHS Chemical - IHS Markit
Eco-Friendly Plasticizers PEP Report 62B Published December 2014 Plasticizers are organic esters, which is compounded into polymers to facilitate processing, and to improve flexibility and toughness of the final products through internal modification of the polymer morphology.
Health, Eco Concerns Give Non-Phthalate Plasticizers a Push
These two groups of non-phthalates have been given a green light for low plasticizer migration in medical-device components made of ABS, PC, PS, and acrylic that come in contact with PVC components. DOTP, HEXAMOLL DINCH IMPROVEMENTS. DOTP and Hexamoll DINCH are two leading non-phthalate alternatives gaining significant ground.
Synthesis and properties of castor oil based plasticizers
Bio-based plasticizers specially used in the fields of medicine or health equipment, packaging, as well as environmentally friendly plasticizers with enhanced mechanical properties have been
- What is DOTP plasticizer?
- DOTP plasticizer is made of imported food-grade vegetable oil, which is hydrogenated and refined. It is a general-purpose green plasticizer and has passed ROHS, REACH and phthalate (ester) 17P certification. DOTP plasticizers show excellent durability, soapy water resistance and low-temperature softness in products. Because of its low volatility.
- What are the advantages of DOTP?
- Because of its low volatility. The use of DOTP can fully meet the temperature resistance grade requirements of wires and cables and can be widely used in cable materials resistant to 70°C (IEC standard of the International Electrotechnical Commission). The plastic products produced by DOTP can completely pass the EU ROHS certification.
- What is the market demand for non-phthalate plasticizers?
- At present, many manufacturers have begun to use non-phthalate plasticizers such as DOTP to replace phthalate plasticizers. Developments in various fields such as medical, packaging, construction, consumer goods, and automotive will drive the market demand for DOTP.
