Wire and Cable Imerys minerals improve the flame retardant properties of wire and cable
Imerys minerals are excellent partial replacements for flame retardants in PE, EVA and APP wire & cable applications.
EVA wire & cable applications
Imerys talc’s hydrophobic and electrically neutral platelets make it an ideal partial replacement for MDH and ATH in EVA compounds for flame retardant (FR) applications, reducing compound costs.
- limits gas emission and oxygen diffusion resulting in delayed combustion
- creates a physical barrier effect limiting heat and mass transfer
- promotes char formation
- improves ash cohesion
- reduces smoke and afterglow
We recommend our high aspect ratio Mistron HAR® talc for exceptional flame retardant (FR) performance in EVA systems.
APP halogen free systems
Imerys mica grades make cost-effective replacements for ammonium polyphosphate (APP) halogen-free flame retardants (FR) for polyolefins commonly used to meet UL94 VO requirements.
- improves dielectric formation
- boosts char formation
- maintains mechanical properties
We recommend our Suzorite® mica products for APP flame retardant (FR) replacement.
Our Suzorite® mica product range is ideal for improving dielectric formation in PVC cables.
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
