Webbof crispness was accounted for the plasticization effect of water within the material. Sauvageot and Blond (1992) found that crispness intensities of Corn Flakes, Rice Krispies, and an experimental extrudate, evaluated by a sensory panel, were high at low storage RH and the crispness varied only slightly with material water activity, aw, The effect of plasticizers on elastic modulus is dependent on both temperature and plasticizer concentration. Below a certain concentration, referred to as the crossover concentration, a plasticizer can increase the modulus of a material. The material's glass transition temperature will decrease, however, at all … Visa mer A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in … Visa mer Concrete In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer … Visa mer • Plasticisers Information Centre • Glass transition • DIDP, *DINP, DBP, BBP, *DEHP, Risk Assessment Reports by the European Chemicals Bureau (ECB).
