Your Trusted Partner for High Quality Proppants & Minerals

Unimin, a member of the Sibelco Group, unites North America’s expertise as the largest supplier of proppant with a worldwide product portfolio. In doing so, we’ve become the first truly global mineral supplier to serve the O&G industry with high quality hydraulic fracturing sands, gravel packing sands, and cementing & drilling additives.

Brands: UNIFRAC® Hydraulic Fracturing Sands, PROPSTAR® Resin Coated Proppants


  • Unifrac® Hydraulic Fracturing Sands
    Pure strength and maximum conductivity...

  • UNIFRAC® Hydraulic Fracturing Sands are produced from geologically mature quartz arenite sands of exceptional purity and structural integrity. These durable proppants will not degrade during handling or pumping, and feature low surface tension properties that minimize proppant induced friction in high shear jobs. UNIFRAC® has excellent initial and retained conductivity under increasing and cyclic closure stress which is attributable to the unique geometry and structural integrity of the monocrystalline quartz grains. Round, spherical surfaces evenly distribute closure pressure to minimize embedment in the perforated layers for highly productive fracture lengths. Excellent suspension properties make UNIFRAC® ideal to extend the proppant pack in longer laterals, maximizing hydrocarbon recovery.

    • Our products have lower turbidity and contain less fines
    • We mine high quality reserves that produce quartz grains that are more spherical and have a higher crush strength
    • We optimize particle size distribution to maximize conductivity
    • UNIFRAC® hydraulic fracturing sand is available locally around the world due to our scale and delivery infrastructure
  • Propstar® Elite™ Resin Coated Proppants
    Maximize crush strength, minimize flowback....

  • PROPSTAR® ELITE™ is an engineered hybrid proppant using premium quality northern white UNIFRAC®. The ELITE coating system enhances the capabilities of natural fracturing sand to deliver superior reservoir performance. Final curing is activated through temperature and pressure once in the fracture.

    • The fully cured element of ELITE provides the strength performance of a precured proppant

    • The retained partial reactivity of the ELITE coating system delivers flowback control with reliable, unconfined compressive strength (UCS)

    • The combination of properties distributes stress over the proppant pack, reducing embedment

    • ELITE™ utilizes monocrystalline quartz, maximizing crush strength and minimizing fines.

  • Propstar® Cyroset™ Resin Coated Proppants
    Flowback control in low temperature reservoirs....

  • PROPSTAR® CRYOSET curable resin coated sand provides flowback control in low temperature environments with exceptional conductivity. This innovative technology enhances the capabilities of natural fracturing sand to deliver superior reservoir performance. No chemical activator is required.

    • PROPSTAR CRYOSET is only coated on premium northern white sand

    • Provides flowback control without the use of a chemical activator eliminating logistical, legal, and safety conerns

    • Delivers superior crush resistance while maintaining proppant pack integrity

    • The curable resin system distributes stress over the proppant pack, reducing embedment
