HIFILL N 800 is a functional nepheline syenite mineral additive for plastic and rubber systems, produced from an all-natural sodium-potassium-aluminum silicate and delivering improved scratch and mar resistance, weatherability, and PVC fusion characteristics with low oil absorption, low tint strength, and high dielectric strength. Median particle size is 7.2 microns with 2.2 m2/g surface area.

MINBLOC HC 1400 is a high-clarity nepheline syenite antiblocking additive for packaging-grade flexible films, combining particle morphology, surface chemistry, and a 1.53 refractive index to deliver antiblocking performance with superior haze, gloss, and clarity without diminishing film mechanical properties. Chemically inert and non-absorptive, it does not interfere with slip agents, antioxidants, stabilizers, or colorants and suits masterbatch or direct addition; median particle size is 7.60 microns with 2.50 m2/g surface area.

MINBLOC HC 2000 is a high-clarity nepheline syenite antiblocking additive for packaging-grade flexible films, combining particle morphology, surface chemistry, and a 1.53 refractive index to deliver antiblocking performance with superior haze, gloss, and clarity without diminishing film mechanical properties. Chemically inert and non-absorptive, it does not interfere with slip agents, antioxidants, stabilizers, or colorants and suits masterbatch or direct addition; median particle size is 8.20 microns with 1.20 m2/g surface area.

MINBLOC HC 500 is a high-clarity nepheline syenite antiblocking additive for packaging-grade flexible films, combining particle morphology, surface chemistry, and a 1.53 refractive index to deliver antiblocking performance with superior haze, gloss, and clarity without diminishing film mechanical properties. Chemically inert and non-absorptive, it does not interfere with slip agents, antioxidants, stabilizers, or colorants and suits masterbatch or direct addition; median particle size is 4.30 microns with 3.30 m2/g surface area.

MINEX 10 is a micronized nepheline syenite functional filler and extender for paints, coatings, adhesives, sealants, and inks, easily dispersed in all conventional vehicle systems and giving brightness, tint retention, weatherability, and stain resistance with minimal resin demand. Median particle size is 2.4 microns with 90.5 TAPPI brightness, 4.9 m2/g surface area, and 31 oil absorption, an ultrafine grade preferred for higher gloss, powder, and clear paint systems.
