Novacite
Malvern Minerals Brand
Supplier:Malvern Minerals
Products:2
Novacite® is a naturally occurring product. The chart above indicates typical particle size distributions. Generally the top size can be controlled through classification machinery; however, sub-sieve distribution and relation above are impossible to predict with accuracy. The nature of fineness or coarseness varies with the character of the crude ore.
Knowde Brand Highlights
- Functional Fillers for Thermosets
- Used for reinforcement and typically increase modulus and strength.
- Constitute up to 70% by volume in oriented composites.
- Discontinuous systems typically do not exceed 30–40% by volume.
- Terminology:
- Reinforcement - mostly used for long, continuous fibers or ribbons,
- Filler, performance filler or functional filler - refers to short, discontinuous fibers, flakes, platelets or particulates.
- Terminology:
- Features of Lamellar Quartz
Barrier Properties
- Platy and Hard
- Overlapping Platelets - parallel to the substrate surface, somewhat like shingles on a roof.
