Magnesium Hydrate Fire Retardant

 

Product description:

Magnesium hydrate fire retardant (MHFR) of CREATE is a nature and mineral fire-retardant based on brucite processed through carefully selected, super and thin smash, surface modified technology and others.

The MHFR is a kind of new high filling product. The product is no poison, no corrosion, environmental protection, no detonation behavior and has excellent fire retarding effect, becoming an important fire-retarding additive for the purpose of fire-retarding and smoke inhibitor.

The MHFR can be widely applied to composites, e.g. electrical wire, cable, PP, PE, PVC, PS, ABS and also to unsaturation polyester, paint and coating, and other plastics and rubbers.

The surface modified MHFR has improved the surface of magnesium hydrate and make it no aggregate to be dispersed into polymers as a fire-retardant. Its fire retardance, physical and mechanical properties has already approached or surpassed the international level of the same kind product.

Qualification

Item	Magnesium hydrate content (%)	Whiteness	Particle size D50 (μm)	Specific surface area (M3.g-1)	Free water content (%)	Packing density (g.cm-3)
Qualification	≥94	≥94	1-6	≥8	<0.3	0.62-0.66

Experiment formulation:

The magnesium hydrate fire retardant can be added with the ratio 20%-60% in PP, PE or PVC.

Product characteristics:

1. Safety and no poison: The MHFR is no poison oneself and does not produce any poisonous air at the decomposition temperature.

2. Good physical property: Although high filling in polymer, the products still keep its rigidity, high heat distortion resistance and high impact strength.

3. Good compatibility with polymer: The exudation and sublimate phenomenon of organic fire-retardant is nonexistent.

4. Compensation intensity: The fire retardant is functional filler since it have some compensation function.

5. High heat decomposition temperature: The heat decomposition temperature of the MHFR can go up to 330°C and 100°C higher than aluminum hydrate fire retardant for satisfying processing actual request of plastics.

6. The hardness of MHFR powder is lower, such it is has smaller abrasion to the equipments, and it is advantageous to the extension equipments service life.

Package Specification:

Kraft paper bag with an inner plastics bag, 20/25 kg/bag.
