Why buy rubber base impression materials online at PinkBlue.in? What are the brands selling rubber base impression materials online?ģM ESPE, Zhermack, GC, Medicept, DMG, Dentsply, Coltene, Meta, Prime Dental, Danville, Detax and Ivoclar are some of the many brands that sell elastomeric impression materials online at PinkBlue.in Polysulfide impression materials yield water as the by product, which has a significant effect on the dimensional stability of the final impression. The catalyst consists of lead dioxide, a plasticizer and retarders to control the setting reaction. The base is a polysulfide polymer containing a multi-functional mercaptan, a filler and plasticizers.

Polysulfide elastomeric impression materials, like the other elastomers are supplied as base and catalyst forms. Polyether elastomers of both types have similar behaviour.

The second type of polyether impression materials are also called as hybrids. Based on the acid catalysed condensation polymerization of the polyether prepolymer with alkoxylsilane terminal groups.Based on the ring opening polymerization of the arizidine rings, at the end of the branched polyether molecules.Polyether impression materials are elastomers that deliver a high level of detail reproduction. The evaporation that takes place due to this by product, results in contraction of the final impression. The by-product of condensation silicone setting reaction is ethyl alcohol. This technique is referred to as the putty wash technique. The putty is used as the tray material and the low viscosity paste is used as the wash impression material. These impression materials are supplied as low viscosity two paste systems or two putty systems. To account for this, certain manufacturers add noble metals such as platinum to act as a scavenger for the hydrogen gas. Although this doesn’t affect the dimensional stability off the impression it can result in pin point voids in the gypsum casts. However, if there is any residual polymethylhydrosiloxane, it can lead to a secondary reaction resulting in the formation of hydrogen gas. Fillers are added to both the base and the catalyst that change the consistency of the products.Ĭorrect proportions of the base and catalyst ensure that there is no formation of by-products. The catalyst contains divinylpolysiloxane and the platinum salt catalyst. The base pase contains both polymethylhydrosiloxanne and divinylpolysiloxane. A platinum salt acts as the catalyst for this reaction. Often referred to as polyvinyl siloxane(PVS) or vinyl polysiloxane (VPS), these are silicone impression materials based on addition polymerization between divinylpolysiloxane and polymethylhydrosiloxane. Elastomers are supplied in base and catalyst forms, which are mixed to result in polymerization of the material. Silicones are further divided into Addition and Condensation Silicones. These are also called as Non-Aqueous Elastomeric Impression materials.Ĭhemically, elastomers can be divided in to three types namely, Silicones, Polyether and Polysulfide. This attribute is similar to that of vulcanized rubber, which regains its original shape after the applied stress has been released. These materials are chemically cross linked when set and have the ability to be stretched and yet recover to their original dimensions. What are elastomeric impression materials?Įlastomers or elastomeric impression materials are a group of synthetic polymer based impression materials.
