Plasticizer - an overview | ScienceDirect Topics
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
Plasticiser loss from plastic or rubber products through
Plasticisers are commonly added to polymers to lower their glass transition temperature and increase their processability, mechanical flexibility, ductility and toughness. 1, 2, 3, 4, 5 They...
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
What Plasticizers Do & How They Affect Properties | Osborne
Plasticizers act like a lubricant among polymer chains to reduce rigidity. Without them, synthetic polymer materials would be too brittle and rigid for any practical purpose. For example, plasticizers give rubber its extensibility. Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers can increase or decrease polymer degradation rates; thus, addition of plasticizers to a disposable biodegradable biopolymer can be used to control the operative degradation rate of the material. Internal or external plasticizers can be used for this purpose.
- How do plasticizers affect processing?
- Plasticizers can influence processing by inducing lower viscosity, faster filler incorporation, easier dispersion, lower power demand and less heat generation during processing, better flow, improved release and enhanced building tack.
- Do plasticizers increase polymers' flexibility at room temperature?
- Disentanglement of CA chains is favored at higher plasticizer content under extensional flow, yielding lower melt strength and higher melt extensibility . These observations confirm that plasticizers increase polymers' flexibility at room temperature and can be used as processing aids.
- How does the type of plasticizer affect biopolymer properties?
- The type of plasticizer can strongly affect the barrier properties, water uptake, and mechanical properties of the biopolymer.
- Can plasticizers reduce material degradation over time?
- The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
- What factors affect plasticizer efficiency?
- Internal mobility (flexibility): This parameter plays a crucial role in determining plasticizer efficiency. This is true for various polymers unless polymer crystallinity is involved. The reduction of Tg is proportional to the temperature difference between the Tg of the polymer and plasticizer.
- How do plasticizers affect tensile strength?
- Generally, increasing the content of plasticizers increased flexibility and decreased tensile strength. It is also seen that SOR provided more flexibility than PEG. All films exhibited hydrophilic surface property, but the water contact angle value increased with the addition of plasticizer.
