William Blythe Stannous Oxide
Chemical Name: Stannous Oxide
CAS Number: 21651-19-4
Chemical Family: Oxides, Tin Compounds
Pigment Type: Inorganic Pigments
William Blythe Stannous Oxide is a high purity tin (II) oxide black powder with wide applicability across a range of sectors including catalysis, life sciences, pigments, plating and process chemicals, a colorant in the glass industry to make ruby glass, as a source of Sn2+ ions in solid state description reactions to produce complex oxides, or in reactions with weak acids to manufacture stannous compounds.

Luxacal™ 202
Function: IR Absorber, UV Absorber
Chemical Family: Oxides, Tin Compounds
End Uses: Digital Ink
Luxacal™ is a doped-tungsten oxide nanomaterial with near infrared (NIR) absorption functionality. The materials size and dopant levels have been optimised for high absorption in the near infrared region and high transmittance in thevisible region making them ideal candidates for use in thermal control glazing applications.

Flamtard H
Chemical Name: Zinc Hydroxystannate
Function: Synergist, Flame Retardant, Solid Lubricant, Smoke Suppressant
Chemical Family: Zinc Salts, Zinc & Zinc Compounds, Zinc Stannates (ZS)
Labeling Claims: Environmentally Friendly, Non-Hazardous
Flamtard H (zinc hydroxystannate) is an insoluble, non-hazardous, antimony-free flame retardant synergist that inhibits the development of flames and smoke in polymers. In halogen-containing polymers, the material has both condensed and vapor phase action during combustion. At 220 °C, the material releases 15w% of water, then at higher temperatures (400 °C - 600 °C) zinc and tin ions exert catalytic activity that inhibits the radical chain reaction causing the flame. In halogen-free polymers Flamtard H can increase the char consistency and strength.

Flamtard S
Chemical Name: Zinc Stannate
Function: Synergist, Flame Retardant, Solid Lubricant, Smoke Suppressant
Chemical Family: Zinc Salts, Zinc Stannates (ZS), Zinc & Zinc Compounds
Labeling Claims: Environmentally Friendly, Non-Hazardous
Flamtard S (zinc stannate) is an insoluble, non-hazardous, antimony-free flame retardant synergist, and is increasingly being used in green applications, particularly in the electronics industry. It is extremely effective in PVC systems for cable sheathing, epoxy resins for printed circuit boards, polyamides and surface coatings. Flamtard S is thermally stable up to 400 °C; at higher temperatures (400 °C - 600 °C) zinc and tin ions exert catalytic activity that inhibits the radical chain reaction causing the flame.

William Blythe Stannous Chloride
Chemical Name: Stannous dichloride
Function: Catalyst, Precursor, Curing, Crosslinking & Hardening Agent, Antioxidant
CAS Number: 7772-99-8
Chemical Family: Tin Compounds, Chlorides
William Blythe Stannous Chloride is a high purity tin (II) chloride available as an anhydrous white powder or as a clear and colorless solution in customised concentrations. Stannous chloride is used for its properties as a catalyst and reducing agent in applications ranging from pharmaceutical synthesis to construction to electronics. William Blythe also offers an application-specific grade of tin (II) chloride solution for the mirror coating industry.

William Blythe Graphene Oxide
Chemical Family: Graphene & Graphites, Oxides
Graphene oxide is an oxidised derivative of the 'wonder material', graphene, with myriad potential applications as a result of its unique properties as a 2D material. William Blythe is a world-leader in the commercialisation of GO, offering a product with unrivalled purity that is manufactured through a safe and inherently scalable route. One of the key benefits to GO over graphene is its ability to be dispersed readily in water, enabling access to 2D sheets via sustainable processing routes, which is why we offer our product already dispersed at a range of concentrations in water. We can also offer a powder products for anhyrdous applications.

Flamtard V
Function: Synergist, Flame Retardant
Chemical Family: Silicates
Compatible Polymers & Resins: Silicones, Polyurethanes (PU), Polyethylenes (PE), Polyvinyl Chloride (PVC), Polyamides, Polypropylenes (PP)
Flamtard V grades are inorganic silicate based flame retardant synergists, chemically modified to control the glass transition temperatures over which they soften (470-500 °C). Above this they convert into a highly viscous molten state in which they can help to reduce the creation and propagation of micro cracks in char formation during polymer combustion. Flamtard V can also improve adhesion of metal oxide residues and oxidised organic materials, leading to mechanically stronger chars. Flamtard V can be used in mica filled silicon based security cables, flame retardant intumescent PVC and PUR materials for the building and construction industry, polyamides and polyolefins. For other polymers, check the potential stability with TGA first. This proven replacement for antimony trioxide can be used alone or in conjunction with other materials in the Flamtard range.
