The cable and wire industry uses both UltraCarb and ATH (Aluminium Hydroxide).
The combination is the difference
UltraCarb is a unique halogen-free fire retardant as it acts differently to traditional fire retardants, which release water in a single action phase. Upon decomposition, UltraCarb provides:
- classical endothermic fire retardant functionality
- PLUS it releases carbon dioxide
- PLUS it provides char stabilisation.
We call this the three-stage fire retardant mechanism. This multi-process fire retardancy offered by UltraCarb:
- releases water at approximately 220°C
- releases carbon dioxide at about 450°C
- and finally, formats the char stabilisation.
This extended fire retardant activity range is what makes UltraCarb so unique.
- cost efficient
We manufacture our unique UltraCarb product range from our own Turkish source of Hydromagnesite and Huntite.
The classic fire retardant
ATH is used in many different applications such as:
- glass reinforced plastic (GRP)
- rubber carpet backing
- latex flexible foams
ATH is compatible with a wide range of polymer types and provides the final product with fire retardancy and smoke suppression. When you expose the ATH filled polymer to fire, it will reduce further combustion and flame spread.
Polymer knowledge is key
At LKAB Minerals, we have an in-depth understanding of the incorporation of UltraCarb and ATH into the polymer matrix to receive the best results possible. In cooperation with partners from the wire and cable industry, we continuously develop our products to make dispersion within the polymer successful. But it’s not all about the product development; it is also about the exact process set up to receive a well-dispersed polymer.
Please get in touch with your local sales manager. We are looking forward to finding the best solution for your wire and cable product.
