APYRAL® with the chemical  formula Al(OH)3, from Nabaltec is an environmentally friendly halogen free product which is used as a flame retardant filler in a wide variety of rubber and polymeric materials. During thermal decomposition APYRAL does not generate toxic or corrosive gases. In addition, there is a distinct reduction in smoke density. It is effective in the crucial phase of the burning process before the outbreak of a fully developed fire.

There are a wide range of APYRAL products available to cover the different requirements of the plastics processing industry. The APYRAL types produced by different products processes can be distinguished by their properties into the five groups below:

1. Standard products
2. Morphology modified products
3. Ground products
4. Viscosity optimized products
5. Fine precipitated products

The quantity of APYRAL added to the organic matrix depends on the required flame retardancy, the properties of the end products and the cost of the mixture. APYRAL can replace other more expensive flame retardants. In addition, the amount of the usually more expensive polymer can be reduced and replaced by the cost effective filler APYRAL. As a result, the total cost of the compound is generally reduced and is therefore more financially favourable.

APYRAL types can be used as a flame retardant filler in the following polymer materials:

• Thermosets
• Elastomers
• Thermoplastics
