JLS-MC series Advantages
◆Higher bulk density to reduce floating dust and increase mix uniformity.
◆Excellent particle distributing to ensure Nylon with JLS-MC better
mechanism and a smoother surface.
◆Well mixing with Nylon resin,so is easier to disperse during processing.
◆JLS-MC810 has even higher disperse property,which ensure Nylon a
better mechanical property .
◆JLS-MC15, MC25 and MC50 is different diameter, which can suitable for
different need.
◆The Nylon which contain JLS-MC is better than Br/Sb system in
electricity isolation capability，it can be used widely in low
piezoelectricity applications.

JLS-MC series Applications
• JLS-MC series consists of JLS-MC15, MC25, MC50 and JLSMC810 based on JLS-MC, which is mostly used in Nylon.
• The series can also be used in a range of polyesters.
• PC,thermoplastic polyurethane
• Thermosets including epoxy resins, unsaturated polyesters and
polyurethane foams.

Heat
Sink: Endothermic decomposition to M and CA
Inert
Gas Source: (M): Dilution of oxygen and fuel gases
Non-burning
dripping (CA): Decrease of exposure to flame
