<strong>Exolit</strong> for polyurethane<br />
With its <strong>Exolit</strong> grades the Pigments<br />
& Additives Division offers an extensive<br />
range of flame retardants for<br />
polyurethane on a non-halogen basis.<br />
The <strong>Exolit</strong> grades exhibit following<br />
characteristics:<br />
<strong>Exolit</strong> in the case of fire<br />
Low smoke gas corrosivity<br />
> Reduced damage of installations<br />
and buildings<br />
Low smoke density<br />
> Extended escape time<br />
<strong>Exolit</strong>-compatibility<br />
Highly effective, low dosage,<br />
high polymer compatibility<br />
> Only slight influence on mechanical<br />
properties<br />
Excellent incorporation into matrix<br />
> No migration<br />
Good recyclability of FR-Polyurethanes<br />
> Meet current and future consumer<br />
recycling requirements<br />
<strong>Exolit</strong>-in final product<br />
Excellent ageing stability<br />
> Low dosage, no migration, high<br />
quality during life cycle<br />
Attractive price/performance ratio<br />
> Competitive systems<br />
Optimal emission behaviour<br />
> Minimization of the exposition risk<br />
of volatile organic compounds (VOC)<br />
Because of these properties <strong>Exolit</strong><br />
flame retardants contribute to meeting<br />
the customer requirement regarding<br />
environmental impact and image.<br />
Polyurethane systems which incorporate<br />
<strong>Exolit</strong> flame retardants can obtain<br />
the most demanding fire tests, whilst<br />
retaining good mechanical properties.<br />
These features allow the materials to<br />
be used in new and demanding fields<br />
of application.<br />

Flame retardants for polyurethane<br />
Under the brand name <strong>Exolit</strong>, Clariant<br />
supplies non-halogenated environmentally<br />
friendly flame retardants with<br />
an assured future in polyurethane<br />
applications.<br />
Application area Test Description Classification<br />

Their advantage lies in their effectiveness,<br />
which enables very low concentrations<br />
to be used, while at the<br />
same time meeting the most stringent<br />
requirements. In the event of fire<br />
involving <strong>Exolit</strong>-containing systems,<br />
a reduction in smoke density is apparent.<br />
Since no halogen-containing flame<br />
retardants are required, no corrosive<br />
gases such as HCl or HBr are released.<br />
These properties are of great importance<br />
in modern vehicle manufacture.<br />

Flexible polyether foam (slabstock and molded foam)<br />
Advantages of <strong>Exolit</strong>:<br />
> Liquid reactive,<br />
incorporable flame retardants<br />
> Low migration<br />
> Low emissions (e.g. low<br />
fogging and VOC-values)<br />
> High flame retardant efficiency<br />
through product life cycle<br />
> Only slight influence on<br />
mechanical foam properties<br />
> Usable in conventional production<br />
facilities by adding directly at<br />
the mixing head<br />
> Good performance in flame<br />
laminating processing (low smoke<br />
emission, good adhesion)<br />
> In the case of fire,<br />
low smoke gas corrosiveness<br />
