Immobile plasticizer in flexible PVC | Nature
When the surfaces of flexible PVC sheets were similarly modified, we found that plasticizer migration could be prevented completely, as it was in PVC tubes. How-ever, modification led to a...
Pevalen - Perstorp
Pevalen has excellent processing properties, high plasticizing efficiency, exceptional UV resistance, low volatility and smoke and is made in a way that reduces the use of finite raw materials. Pevalen is the perfect choice for flexible PVC applications such as Coated fabrics, PVC plastisol, and flexible film. Betty Lu VP Oxo chemicals
PlastomollDOA
Plasticizer for PVC, surface coatings and rubber. Plastomoll DOA is especially suited for flexible PVC colorants and coatings requiring good low temperature properties. Plastomoll DOA meets the requirements for food packaging and can therefore be used for flexible PVC films for food contact (cling film).
Eastman Plasticizers for PVC
Benzoflex - 181 Plasticizer Benzoflex181 is a water white alkyl benzoate ester with low odor, low viscosity and excellent compatibility with PVC. Benzoflex181’s principal use is as a low viscosity plasticizer for plastisol applications. Benzoflex 181 may also be used in other applications requiring a low viscosity, high solvating plasticizer.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Due to its low cost and generally good performance, DEHP is widely employed as a plasticizer in manufacturing articles made of PVC. Melting point: 50°C Boiling point: 250 - 257°C at 0.5 kPa Structure of DEHP DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength.
- Where can plasticizers be used?
- The plasticizer can migrate from PVC-based devices and storage bags into physiological fluids, however, and has been detected in storage media such as blood, plasma, serum, drug solutions and fatty foods 2, 3, 4, as well as in the bodies of patients undergoing haemodialysis and transfusion 5.
- What is plasticized poly (vinyl chloride)?
- Nature 396 , 638 ( 1998) Cite this article Plasticized poly (vinyl chloride) (PVC) is one of the most widely used polymeric materials in medical and related applications, and usually contains up to 40 per cent di- (2-ethylhexyl)phthalate (DEHP), which acts as the ‘plasticizer’ to impart flexibility to an otherwise rigid PVC 1.
- Can plasticizer migration be prevented?
- When the surfaces of flexible PVC sheets were similarly modified, we found that plasticizer migration could be prevented completely, as it was in PVC tubes. How-ever, modification led to a decrease in the stress (about 8 per cent) and strain (about 28 per cent) at the breaking point for PVC sheets.
- How can PVC be prevented from migrating to other polymers?
- Attempts to prevent this migration have included coating, grafting or blending PVC with other polymers, glow-discharge treatment of the surface of PVC, prolonged ultraviolet irradiation, and photocrosslinking of dithiocarbamated PVC 10.
