The patents that quietly run your plant.
A curated, editorial reading of the public patent record around gypsum board manufacturing. Each entry strips the legal scaffolding and rebuilds the chemistry and process consequences in language a plant engineer can act on, with annotated diagrams of the mechanism.
Summaries are NGL editorial readings of published abstracts and granted claims. Always consult the full granted document and qualified counsel before any commercial decision.
The patent family that reframed what a half-inch board weighs and forced a three-year industry catch-up.
Defines a surfactant pair whose differing interfacial elasticities engineer a controlled, partially-collapsing foam in the set core.
Foundation chemistry for silicone-grafted hydrophobization of the dihydrate crystal surface.
Defines a PCE comb-polymer architecture specifically tuned for the calcium sulfate hemihydrate / dihydrate equilibrium.
Elevates starch loading and re-engineers the migratory–non-migratory balance to carry the bond through a lightened core.
Defines a glass-fiber and unexpanded-vermiculite loading that holds the core together after both bound-water dehydrations.
We strip the document to three things: what is being protected, what the mechanism actually is, and what changes on your line if you operate inside, around, or on top of the claims.
Help you infringe. The hub is an engineering education resource. Where a formulation direction lives inside live claims, we will say so and route you to a non-infringing architecture.
We maintain working files on roughly 140 board-relevant patents. If you need a written read on a specific document or family, ask via Contact.
