The business unit Antimony offers multiple variants of antimony trioxide and antimony pentoxide for applications in fire retardant plastics, as a catalyst or as an additive in the glass or ceramics industries.

Antimony oxide in Fire Retardant Plastics

textile truckAntimony trioxide acts as a synergist, in combination with chlorinated and brominated polymers and additives.

The synergistic action of antimony trioxide or antimony pentoxide, in combination with chlorine & bromine radicals radicals, is known as the most effective fire retardant combination.

In PVC, antimony trioxide is the logical partner to enhance the fire retardancy for many building & construction and automotive applications.

textile canvasIn other plastics, antimony oxide, combined with halogenated additives, are by far the preferred choice when besides excellent flame retardant properties also good physical properties are demanded.

Campine has developed a wide range of antimony oxide particle sizes to cover the need for homogeneous distribution in plastics, as well as keeping the benefit of optimal mechanical properties and transparency. Campine was the pioneer in developing antimony trioxide grades with minimal interference with pigments, resulting in a constant colour and a cost effective  pigmentation.

Alternative flame retardant additives require a high loading and thereby reduce the physical strength of the plastics and prohibit transparency.

cablingOnly antimony trioxide enables an effective synergy that is functional at low loading levels.

The colloidal solution of antimony pentoxide is designed for thin coatings on textiles and can be incorporated in the thin fibres for nonwovens & textile weaving.


Antimony oxide as Catalyst

PETAntimony trioxide and antimony pentoxide have catalytic effects on multiple chemical reactions.

Campine offers an ultra pure product range for these catalytic applications.

Antimony trioxide is the most effective polycondensation catalyst for PET polymerisation: it is applicable for PET bottles, fibres and films.

Antimony oxide in Glass and Ceramics

ceramicAntimony trioxide is used in glass as a refining agent to decolorize and degasify the glass.

For ceramics and enamels, antimony trioxide functions as an opacifying agent.


And many other applications

Campine's BU antimony offers customised solutions for all industrial area’s.

Antimony trioxide is part of multiple pigment solutions to create a specific colour effect.

In lubricants antimony trioxide is used as an antifriction agent.

Many more industrial applications are facilitated by the use of antimony trioxide or antimony pentoxide:

When you are working on a specific function of antimony trioxide or antimony pentoxide, Campine is your partner to define and produce the right product-variant for an optimal performance in your application.
