Product Characteristics
All HEYI® magnesium mineral products have the following outstanding characteristics to make it the ideal substitute building product for your choice.
Outstanding Fire Performance
Non-combustible class A building material; Fire-resistant temperature ≥ 12000C; Can achieve fire ratings as high as 4 hours given the correct installation. The best fireproof and flame retardant performance building materials of all the inorganic building materials, the best fireproof and flame retardant sheathing building materials of light & heavy steel structure buildings
Eco Friendly
100% Free of harmful substances e.g. asbestos, formaldehyde, benzene; No poison smoke in case of fire, no inorganic volatiles; creating a green & healthy living space
Tough & Impact Resistant
The highest strength & highest tenacity sheathing building materials of all the inorganic building materials, 3 times strength of cement building materials with same density; Stronger and more rigid to allow thinner
material to do the same job .
Damp Proof
Moisture proof, softening coefficient is 0.95-0.99, strength loss is less than 1-5% after several days soaking in water test
Insulation against Heat & Cold
Lower heat conductivity coefficient than same density gypsum and fiber cement board, better heat & cold insulation performance
Durable & Anti-Corrosion
Anti-corrosion, ageing resistant, wear-resisting, high surface hardness, long service life, can be widely applied to be the sheathing building materials of steel structure in the field of chemical, electroplate, refining and
breeding industry which need additional anti-corrosion protection
