The use of inhibitory calcium carbonate as additive for a composition containing at least one polymer different from cellulose, wherein the inhibitory calcium carbonate is obtainable by means of a method in which calcium carbonate particles are coated with a composition comprising, based on its total weight, at least 0.1% by weight of at least one weak acid. Further described is a composition containing at least one polymer different from cellulose and inhibitory calcium carbonate.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles and a polymer material comprising at least one thermoplastic polymer and at least one thermally curable polymer precursor. At a sufficient temperature, the at least one thermally curable polymer precursor may undergo a reaction, optionally also undergoing a reaction with the piezoelectric particles, and form an at least partially cured printed part. The piezoelectric particles may be mixed with the polymer material and remain substantially non-agglomerated when combined with the polymer material. The compositions may define a form factor such as a composite filament, a composite pellet, or an extrudable composite paste, which may be utilized in forming printed part by extrusion, layer-by-layer deposition, and thermal curing.

A chemical composition for use with polyvinyl chloride that may be used to increase the rate at which the polyvinyl chloride breaks down or disintegrates after being discarded as the surface gradually forms defects, holes, or cracks, including when in a landfill, wherein the chemical composition includes the chemicals PBAT, PCL, EVA, CPE, PLA, PGA, PHA, PHB, PE, PVA, PBS, PPC, and PET.
