Under the trade name CUBLEN, Zschimmer & Schwarz markets a wide range of phosphonate products. The focus of the portfolio comprises eight different chemical molecules (HEDP, ATMP, DTPMP, EDTMP, HDTMP, HEMPA, PBTC, BHMTMP), which are supplied in numerous different forms. Most of the products are offered as various salts – e.g. sodium (Na+), potassium (K+), ammonium (NH4+) – with a different pH value or active content. The CUBLEN phosphonate range of Zschimmer & Schwarz provides optimum solutions for the formulation of detergents and cleaning agents. CUBLEN phosphonates are the products of choice for use as high-performance antiscalants, dispersants, complexing and chelating agents or as corrosion inhibitors.
The CUBLEN A series (ATMP) is a good complexing agent and a universally applicable inhibitor for various mineral deposits (scale). Selected ATMP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water. CUBLEN ACS 402 is also compatible with active chlorine.
The CUBLEN B series (BHMTMP) is an excellent inhibitor for both carbonate- and sulphate-based mineral deposits with high hydrothermal stability.
The CUBLEN D series (DTPMP) represents the most versatile phosphonic acid in the CUBLEN product range and impresses with its outstanding price–performance ratio. DTPMP is an excellent inhibitor for mineral deposits (for example CaCO3, BaSO4, SrSO4) and a powerful complexing agent. Selected DTPMP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water.
The CUBLEN E series (EDTMP) is a particularly powerful complexing agent with high calcium tolerance. EDTMP has a high dispersing power for ceramic slurries and retards setting in building materials.
The CUBLEN F series (HDTMP) acts as an excellent inhibitor for mineral deposits (especially for gypsum) and has high hydrothermal stability. HDTMP shows corrosion-inhibiting properties on aluminium under alkaline conditions. Selected HDTMP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water.
The CUBLEN K series (HEDP) is a very good CaCO3 inhibitor, water hardness stabiliser and complexing agent for trivalent metal ions (for example Fe3+). Selected HEDP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water. In addition to aqueous products, HEDP is also available as a granular, dust-free solid with various active contents.
The CUBLEN R series (HEMPA) is an excellent dispersant for calcium-based deposits. HEMPA significantly improves the rinsing properties of washing and cleaning formulations.
In highly saline systems of oilfield applications, HEMPA can show its excellent calcium tolerance.
The CUBLEN P series (PBTC) consists of an active chlorine-compatible phosphonic acid with high calcium tolerance, even under strongly alkaline conditions.
