Polymer Additives

FLAMTARD H is a flame retardant synergist that can increase char consistency and strength, and reduces the risk of flame ignition and smoke development.

It can be used in paints, PVC wall coverings, flooring, wire & cable, artificial leather and in rigid technical profiles. It can also be used as a transparent conductive oxide in the manufacture of films for solar cells, touch screens and energy efficient glass, for polymer processing at temperatures below 220°C, and as a solid lubricant additive in friction materials.

In halogenated plastics, FLAMTARD H has flame retardant properties in TWO temperature zones – At 220 °C it releases 15wt% of water, which helps extinguish flames. At 400 °C - 600 °C, the zinc and tin ions can be volatilised or liberated from their structure using a halogen source to exert condensed or gas phase catalytic activity. In this way, it can partially replace antimony.

In halogen-free flame retardant polymer materials that use phosphor-based flame retardants, FLAMTARD H can be incorporated into the plastic as a synergistic additive to increase char consistency and strength.

It poses no human health or environmental hazards and has been listed as a sustainable product by OEKO-TEX, one of the most trusted names in the certification of safe and sustainable raw ingredients for the leather and textile industry.

It is available as a powder in both standard and free-flowing grades.

FLAMTARD S is a flame retardant synergist that can reduce the flammability of polyamide engineering plastics. It can be used in applications such as polyamide electronic connectors, relays, switch gear, circuit breakers and electric vehicle transmission components.

It is insoluble in water and thermally stable up to 1000°C.  In the presence of a Br flame retardant source, zinc and tin ions can be volatilised or liberated from their stannate structure between 400°C and 600°C to exert catalytic gas phase activity. This means FLAMTARD S is suitable for exploring partial antimony replacement in halogenated FR polyamides. It also poses no human health or environmental hazards.

Specific applications include as a transparent conductive oxide used in the manufacture of films for solar cells, touch screens, and energy efficient glass; as a smoke suppressant and flame retardant synergist with co-flame retardants; for polymer processing at temperatures above 220°C; as a co-additive in phosphate flame retardant containing polymer formulations to optimise char formation; and as a solid lubricant additive in friction materials.

It is available as a powder in both standard and free-flowing grades.

FLAMTARD V100 is a range of inorganic silicate-based products, primarily designed to be used with FLAMTARD H in PVC applications where it can replace antimony in a more cost-effective way. Typical applications include PVC artificial leather, wall coverings, floorings, plastisols and wire & cable.

FLAMTARD V100 is chemically modified to control the glass transition temperatures (470-500°C). Above these temperatures, 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-based flame-retardant formulations.

FLAMTARD V100 is exempt from REACH registration due to its amorphous inert substance properties. It also has proven below-threshold metal leachability concentrations, confirmed in a dissolution/transformation study.

Potassium iodide and cuprous iodide are used as a heat stabilising combination for engineering polyamide plastics, combustion engine and electrical vehicle components.

Copper iodide is a catalyst for decomposing of hydro-peroxide groups that would otherwise cause long-term degradation to polyamide engineering plastics at high temperatures. This makes is suitable for applications in combustion engines and electric vehicle components. Potassium iodide, when combined with copper iodide, reacts stoichiometrically withy hydro-peroxide groups to deactivate the chemical instability they cause.

We can create specific product forms and packaging for you, which can improve the quality of logistics, storage and manufacturing dispersion, and drive improved product performance.

Anhydrous tin dichloride is an essential co-catalyst in the resol-crosslinking reaction between diene groups in EPDM or other rubbers in thermoplasic vulcanisate manufacturing. It can help prevent overdosing, odour emission issues, plate-out during production and other in-service effects.

As is well known, anhydrous tin dichloride is prone to absorbing moisture from the air which causes caking in the short term and corrosion to metal surfaces in the long term. We can help you avoid these effects by defining the right product form and packaging solutions for your manufacturing operations.
