FR-20-100

Chemical Name:
Magnesium hydroxide
Formula:

Mg(OH)2

CAS Number:
1309-42-8

General & Use:

FR-20-100 is a high purity Magnesium Hydroxide,based on mineral raw material from the dead sea and special production technology. It is a non-halogen flame retardant with low smoke emission.

During the decomposition process no toxic or corrosive gases are generated. In addition, it is an excellent smoke suppressant and acid scavenger. Its high thermal stability (up to 340°C) enables its use in high performance polymeric formulations.

FR-20-100 is used in Polyolefins, Polyamides, PVC and other thermoplastic polymers. Common end applications are wires and cables, injected molded articles for electronics and home appliances.

There are three basic grades denoted as FR-20-100-S5, FR-20-100-S7, and FR-20-100-S10. The S5, S7 and S10 relates to surface areas of 5m²/gr, 7m²/gr and 10m²/gr respectively.

FR-20 is also available in surface-treated grades which are suited for specific applications.
