This Vermiculite product is manufactured using the highest quality materials available and it is micronized down to a controlled particle size distribution. A certain amount of inter-laminar water still remains bound in this product and this will give rise to some intumescent characteristics.
DM440 is used as an additive to formulations which require improved resistance to fire whilst retaining the base mechanical properties of the plastic/polymer system.
