Phenolic Molding Powder - High-temperature Thermosetting Polymer For Single-use Molds | Grade A, Exceptional Tear Resistance, Low Mold Shrinkage

Molding powder is made available by us for use in the various commercial and industrial applications. It is a kind of thermos setting plastic polymer that is capable of withstanding high temperatures and pressures. The offered powder is very effective and made for use in the various purposes. The phenolic resins are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, they were the first commercial synthetic resins. This step-growth polymerization reaction can be either acid- or base-catalyzed. It is used for making single-use molds of larger body parts including faces heads and torsos, and craft molds where high tear resistance and low mold shrinkage is required. To reveal your casting, the alginate is peeled off the surface of the casting. There usually is no way to reuse an alginate mold as it is broken into chunks when being removed.
