  • plasticizers: types, uses, classification, selection & regulation

    Plasticizers: Types, Uses, Classification, Selection & Regulation

    Plasticizers are commonly classified based on their chemical composition. It is possible to understand the influence of structural elements (e.g. different alcohols in a homologous series of phthalates, adipates, etc.) on the properties of plasticizers and their effect on base polymers.

    What Plasticizers Do & How They Affect Properties - Osborne

    Types of Plasticizers. Plasticizers are constantly being evaluated for safety. Because of the widespread usage of plasticizers, they are widely researched and subjected to extensive testing for possible health and environmental effects. In the past sixty years, over 30,000 different plasticizers have been developed worldwide.

    Therefore, enhancement of WCPO into high quality oil offers an alternative to be utilized for wide range of applications, thus reduce the environmental effect causes by its disposal problems.

  • plasticizer

    Plasticizer

    A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of plasticizer needed to obtain a certain hardness or elongation is a measure of its efficiency.

    Effect of plasticizer on structure—property relationship

    The effect of plasticizer concentration on changes in structure/microstructure and their correlation with physical properties has been investigated and reported. A substantial enhancement in the electrical conductivity, by two orders of magnitude at room temperature, of the PCPE has been noticed when compared with that of composite polymer

  • use of water reducers, retarders, and superplasticizer

    Use of Water Reducers, Retarders, and Superplasticizer

    The use of superplasticizers may produce high strength concrete (compressive strength up to 22,000 psi). Superplasticizers can also be utilized in producing flowing concrete used in a heavy reinforced structure with inaccessible areas. Requirement for producing flowing concrete is defined in ASTM C 1017.

    Polymer

    Inclusion of plasticizers tends to lower T g and increase polymer flexibility. Addition of the plasticizer will also modify dependence of the glass-transition temperature T g on the cooling rate. The mobility of the chain can further change if the molecules of plasticizer give rise to hydrogen bonding formation.

    Edible films based on starch and chitosan. Effect of starch

    Edible films based on starch and chitosan were obtained by varying the starch source (potato and cassava starch), starch concentration (0.5 and 1.0%), type of plasticizer (glucose and glycerol), chain length of the surfactant's hydrophobic tail (12 or 18 carbons) and mechanical treatment (0.5 or 4 min stirring time) during the preparation of the film forming solution.

    Phthalate

    A plasticizer based on vegetable oil that uses single reactor synthesis and is compatible as a primary plasticizer has been developed. It is a ready substitute for dioctyl phthalate. [15] And several other bio-based plasticizers have been and are being developed as alternatives to phthalates [ citation needed ] .

    Plasticizer Effect on Oxygen Permeability of β-Lactoglobulin

    Plasticizer effect on oxygen permeability (OP) of β-lactoglobulin (β-Lg) films was studied. Propylene glycol (PG), glycerol (Gly), sorbitol (Sor), sucrose (Suc), and polyethylene glycol at MW 200 and 400 (PEG 200 and PEG 400, respectively) were studied due to their differences in composition, shape, and size. Suc-plasticized β-Lg films gave the best oxygen barrier (OP < 0.05 cm3·μm/m2

    Effects of Temperature and Water Content on the Secondary

    The effect of temperature on gluten conditioned at the following water contents, 0%, 13%, and 47% (wet weight basis), was studied by FTIR spectroscopy over the temperature range of 25−85 °C. A detailed discussion of the assignment of the amide I band is given. At 0% hydration no changes in the secondary structure with temperature could be detected; spectra were consistent with a tight
