Plasticizer - an overview | ScienceDirect Topics
By changing type and amount of plasticizer, properties can be tailored to requirements. Increasing plasticizer concentration increases flexibility, decreases tensile strength, and reduces hardness (e.g., Figure 1 ). PVC itself does not readily burn, but the addition of plasticizer increases flammability.
Plasticizers: Types, Uses, Classification, Selection & Regulation
A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers generally affect the viscoelastic properties of the base resin; whereas, diluents would simply reduce the viscosity of the system. Whereas diluents ultimately result in brittle, hard adhesive systems, plasticizers result in increased flexibility and lower modulus.
What Plasticizers Do & How They Affect Properties | Osborne
PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage. Because plasticizers can make the material stronger than before, PVC is largely used in the construction, automotive and wire and cable sectors.
Chemical Admixtures - Cement
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or
- Does plasticizer concentration affect thermal properties of s-plasticized films?
- Change in plasticizer concentration showed an insignificant effect on the thermal properties of S-plasticized films. The glass transition temperature of SPS films slightly decreased as the plasticizer concentration increased from 15% to 45%.
- Do plasticizers affect mechanical properties?
- For food packaging applications, mechanical properties are of vital importance, so it is highly important to have general knowledge about the effect of plasticizers on mechanical properties, as well as on physical, thermal, and barrier properties, to be able to develop successful packaging materials.
- Does plasticizer type and concentration affect biodegradable films?
- Generally, the current study verified that plasticizer type and concentration affects the mechanical, thermal and barrier properties of plasticized SPS films. In summary, this paper presents a potential biopolymer for the development of biodegradable films.
- Does plasticizer type affect chitosan/Zein film rheological and structural properties?
- The chitosan/zein film with PEG-400 exhibited superior properties. The purpose of this study was to evaluate the effect of plasticizer type (glycerol, PEG-400, and sorbitol) and concentration (0%, 15%, 30% and 45%, w /w dry polymer weight) on rheological and physico-mechanical and structural properties of chitosan/zein blend film.
- Does plasticizer type affect optical properties of bioactive edible films?
- The effects of plasticizers type and concentration on the optical properties of bioactive edible films were shown in Table 3. The result indicated plasticizer improved the opacity of chitosan/zein blend films, and the opacity of films was increased significantly (p < 0.05) with an increase of plasticizer concentration.
- Do plasticizers affect tensile strength?
- The different plasticizers utilized in the film-forming solution have remarkable effects on the tensile, thermal and barrier properties of the resulting films. In all the plasticized SPS films, the tensile strength decreased with plasticizer content from 15%–45%.
