Product Characteristics

All HEYI® magnesium mineral products have the following outstanding characteristics to
make it the ideal substitute building product for your choice.

a

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

b

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

c

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 .

d

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

e

Insulation against Heat & Cold

Lower heat conductivity coefficient than same density gypsum and fiber cement board, better heat & cold insulation performance

f

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

Why HEYI is the best

1. Advanced Technology System
Based on 10 years of professional theory & production practice experiences, researched & developed advanced technology system, including product modifier, special function annexing agent

2. High Quality Raw Materials
High active magnesium mineral powder & high active silica as main materials; high quality wooden fiber & high strength middle-alkali platinum fabric glass cloth as reinforcing materials; strict raw materials factory inspection

3. Dynamic Formula Production Technology
According to the performance requirements of different products, to design the molar ratios, and then based on the technical index of raw materials, dynamically determine best production formula, to achieve the best proportion of various raw materials ratio and the best crystal molecular structure inside the product

4. Strict Standard Production Process
Under the strict control of dynamic formula production process, conduct the production in accordance with the standard production procedure, definitely don’t reduce the production material cost by increasing the quantity of the additional stuffing materials and sacrifice the long term quality performance of the products; Auto CNC raw materials weighing system to precisely control the quantity of the needed materials, standardized raw materials mixing process, ensure the full mixing of the raw
materials

5. Standardized Product Curing System
Auto adjust temperature and humidity system, 15 days second maintenance with constant temperature & humidity; ensure sufficient internal chemical reaction and formation of internal stable 5-1-7 molecular structure

6. Thorough Finished Product Inspection
Random sampling from each batch of product to conduct physical & chemical inspection; product quality technical standard; quality assurance certificate
