New Pevalen Pro plasticizer gives flexible PVC an
Perstorp is launching a new renewable polyol ester (non-phthalate) plasticizer Pevalen Pro. It will make flexible PVC an even more attractive choice of plastic, based on a significantly lower carbon footprint versus competing materials and technologies. Pevalen Pro not only gives PVC an environmental boost as a renewable true non-phthalate plasticizer but also provides superior performance
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.
Poly Vinyl Chloride Additives and Applications-A Review
The basic structure of PVC is (C2H3Cl)n and it is produced by polymerization of the vinyl chloride monomer (VCM) with a polymerization degree ranges from 300 to 1500. The chlorine content in PVC is...
High Molecular Weight Phthalates Plasticizers
ExxonMobil Chemical offers the broadest range of High Molecular Weight phthalates plasticizers to offer optimal balance of performance and safety. Their compatibility with PVC and low volatility make Jayflex the plasticizers of choice when it comes to end products that are required to be durable and safe to use.
An efficient bio-based plasticizer for poly (vinyl chloride
Nevertheless, to date, most of the bio-based plasticizers show poor comprehensive performance compared to those based on petroleum. For example, cardanol derivatives, when used as plasticizers for PVC, had poor compatibility and precipitation resistance, which limited their use to only a small amount of additive (Harte et al., 2013; Jia et al
- What is the role of plasticizers in PVC?
- Understanding the role of plasticizers is crucial, as they significantly influence the properties and applications of PVC. They impact flexibility, durability, and processing efficiency. These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare.
- Are plasticizers compatible with PVC?
- The molecular structure of plasticizers largely determines their effectiveness and compatibility with PVC. Plasticizers typically consist of large molecules that are capable of inserting themselves between PVC chains. This insertion effectively reduces intermolecular forces, allowing the PVC to become more flexible.
- What are the requirements for plasticizers in flexible PVC?
- Plasticizers in flexible PVC must be closely associated with the amorphous part of the polymer at room temperature, and plasticizers must be fairly permanent. The plasticizer must act as a solvent for the crystalline part of the PVC at flexible PVC processing temperatures but not at lower temperatures.
- Are phthalate plasticizers good for PVC?
- Phthalate plasticizers have been the conventional choice in the PVC industry for many years. They improve the flexibility and processability of PVC, making it suitable for a wide range of applications, such as pipes, vinyl flooring, and medical devices.
- Are PVC resins compatible with plasticizers?
- Compatibility between plasticizers and PVC resins is another fundamental aspect that determines the overall performance of the final product. A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties.
- Which plasticizers are used in stretch PVC films?
- Considering the tensile properties, all samples will probably show adequate performance when used as stretch PVC films with slight differences between them as follows: The plasticizers ATBC, DEHT and polyadipate showed lower plasticization efficiency than the others since samples 2, 4 and 6 showed the highest tensile strength values.
