Polymer chains are held together in these materials by relatively weak intermolecular bonds, which permit the polymers to stretch in response to macroscopic stresses. 5.1 Packaging requirements. Apart from the chemical nature of the material, the primary method of classification is according to consistency. In the present study, the lack of significant differences between these two types of elastomeric impression materials under this testing suggested that both of these materials can reproduce the required details. Typical values for the linear coefficient lie in the range 150 ~ 300 MK-1 (Fig. Elastomers Dr. Arpit Viradiya. flexibility/stiffness property ranges of materials so as to determine whether the set materials, when formed as impressions, can be removed from the mouth without injury to impressed oral tissues and will have adequate stiffness in the more flexible portions of impressions to resist deformation when model-forming products are poured against them Dimensional stability of elastomeric impression materials: a critical review of the literature. During working time the flow properties of elastomeric impression materials are essentially influenced by their storage and material temperature, respectively. Your email address will not be published. This study aimed to compare two impression tech-niques for analogue implants: the direct (or pick-up) technique with the elastomeric material polyether, and a digital scanner (True Definition, 3M ESPE), in order The mixed materials, contained in a metal mould, were placed in a 37 °C water bath 2 min after mixing and remained in the bath for … to improve on the precision of conventional impression procedures using elastomeric materials. a. polysulfide.
