Nature own fire retardant. Hydromagnesite Chemical formula:
[3MgCO3 · Mg(OH)2 · 3H2O].
This unique natural minerals is also
known as HMH. It is a proven fire retardant filler in a wide range of polymers and rubbers such as EVA, POE, polyethylene(PE), polyvinyl chloride (PVC), ethylene-propylene diene monomer (EPDM) and Nitrile Rubber (NBR).
HM2V is naturally precipitated hydromagnesite beside the salt lake, with very high purity and whiteness. Milled and coated by KMT patent method, so it's a low carbon green product, can be used to increase LOI and reduce somke density of FR PVC compound.
Application
synergy with ATO or use along to increase LOI of FR PVC compound, reduce smoke density.
Advantages:
Low carbon green product from nature.
Good replacement of ATO (15hpr HM2V=1phr ATO)
Reduce FR PVC smoke density
High whiteness, not cause compound color change because of it's high purity
Low density
