Alginate Impression Material is derived from dental impression material, distinguished by slower setting times. EnvironMolds offers two groups of alginates.

The first group is a silica free formula wwhich is both environmentally and user friendly. It is a softer set, ideal for babies and small children as it is very gentle on the model. The silca free formula provides a much greater coverage as its mix ratio is 1 part powder to 7 parts water, making it the most economical formula on the market by volume.

The second type of alginate is the traditional formula which provides for a firmer set due to its clay fillers. But the traditional formula has the classic mix ratio of 1 part powder to 3 parts water.

EnvironMolds also offers Fibergel alginate which contains fiber to both improve tear strength and to hold moisture to delay shrinkage. This is an excellent formula for larger molds and lifecastings.

Alginates are know as waste molds as they usually only can be used for one, perhaps two castings as they will shrink through time as the water evaporates. Thus, you should cast into your alginate mold within 3 hours for best results. The exception being FiberGel which allows for a twelve hour delay before shrinking.

We also offer Moulage which is heated to melt and then applied to the subject. After use it can be remelted and reused.
