ABT® 1000 Antiblock Talc |
| ABT® 1000 Antiblock Talc is designed for those applications where higher clarity and reduced haze are required, compared to our standard ABT® 2500 antiblock talc. It is produced from beneficiated high purity Montana Talc ores. The beneficiation process provides unrivaled consistency in the final product's purity and compounded color. Product uniformity is assured by in-process control of all aspects of the manufacture. This delivers a product with a particle size distribution that balanced antiblocking efficiency and optical properties. |

VICRON® |
The VICRON® series of fine ground limestone represents a full range of high calcium limestone products for general purpose filler applications. VICRON® limestone products are characterized by their controlled particle size, low surface area, high brightness and low oil absorption relative to other industrial minerals. They find use as extenders and property enhancers in paint and coating formulations, thermoplastic and thermoset polymers and many types of building products.
Uniformity is insured by the careful control of all processing conditions. These VICRON® products are manufactured from a high quality deposit of limestone located in Adams, MA, and therefore, have consistent chemical and mineralogical composition. |
