Company Overview

National Silicates Ltd. (NSL) is a wholly owned Canadian subsidiary of The PQ Corporation. The PQ Corporation in conjunction with its affiliates is the world's largest producer of sodium and potassium silicates with manufacturing facilities in 17 countries on five continents.

Our products are available in a variety of forms: liquids, powders, solids, and alkaline crystals known as metasilicates, that serve a growing number of customer needs. NSL and The PQ Corporation also produce magnesium sulphate, commonly known as epsom salt, available as liquid and crystalline products.

NSL's headquarters is in Toronto, Canada. The production and distribution facilities for sodium silicates are located in Valleyfield, Quebec; Toronto, Ontario; Ft. Frances, Ontario;

Whitecourt, Alberta; Surrey, British Columbia; and Parksville, British Columbia. Magnesium sulphate is produced at Surrey, BC;

Berkeley, CA; and Utica, IL.

NSL has been serving customers in Canada since 1931, but as a subsidiary of The PQ Corporation, has experience in the chemical manufacturing industry beginning in 1831. NSL has built its business through a commitment to helping its customers succeed in their own businesses. This commitment ensures that customers consistently receive superior products accompanied by a high level of technical support for optimal use.

National Silicates' plants and offices are ISO-9002 registered and verified under the Canadian Chemical Producers Association Responsible Care Initiative (Phase 1).

INDUSTRIAL APPLICATIONS

The environmentally friendly nature of sodium and potassium silicates and magnesium sulphate, in combination with a distinct set of chemical properties, makes these products well suited to a vast and growing number of industries and end-uses including:

PULP AND PAPER

NSL is the world leader in the use of sodium silicates and magnesium sulphate for peroxide stabilization in pulp bleaching, deinking, scale prevention, and oxygen delignification. Our laboratory and technical service capabilities focus on reducing overall chemical bleaching costs.

MINING

Silicates are used as anionic dispersants and depressants in mineral flotation.

WATER TREATMENT

Silicates are used as corrosion inhibitors and flocculant aids in municipal water treatment systems, and as iron and manganese sequestrants for the treatment of well water.

PEROXIDE STABILIZERS

Silicates stabilize peroxide and increase its efficiency in a variety of end-uses from pulp and paper and textile bleaching to waste water treatment.

OILFIELD

Silicates are used in the oilfield for lost circulation; cement additives; dewatering sludge or reclaiming used oil; and drilling mud slurry thinners.

DETERGENTS

Silicates provide a range of benefits including agglomeration of detergent granules, corrosion inhibition, emulsification properties and pH buffering.

CORE AND TUBE MANUFACTURING

Silicates provide adhesion for these paper products as well as improving crush strength.
