Limestone acts as a functional filler in the production of molded and extruded plastic parts, including plastic pipes, electrical boxes, wire and cable, calendared film, plastic furniture, construction barriers, vinyl siding and floor tiles. It is also used as filler in resins for spray-up fiberglass (bathtub and shower) and resin-cast products, such as cultured marble. Limestone filler can replace expensive crude oil-based plastic materials.
Our products are carefully controlled in terms of chemistry and particle size to reduce variances in viscosity and flow. They also reduce or eliminate wear and abrasion in extruding equipment. Tailor-made blends are available to optimize desired properties such as particle packing, modulus of rupture, stiffness and opacity, as well as tensile and compressive strength.
