Tile Backer Boards

It features a polymer nano-quartz coating and is combined with alkali-resistant, high-strength fibers for excellent thermal insulation. It effectively prevents moisture penetration and dampens humidity during use, effectively addressing the heavy and difficult installation issues of traditional cement backboard. Ordinary XPS board suffers from weak surface bonding and poor impact resistance. This three-layer composite structure combines lightness and strength with thermal insulation and waterproofing, making it suitable for multiple scenarios. XPS board is the foundation of lightweight and thermal insulation. Its density is only 30-40 kg/m³. When renovating older buildings, it eliminates the need for a reinforced base layer, making it easy to transport and install. The polymer nano-quartz coating blocks water vapor penetration. Quartz particles with a size of ≤50 nm are evenly distributed throughout the coating, forming a dense waterproof membrane that prevents moisture from penetrating. The alkali-resistant, high-strength fibers provide impact and deformation resistance. The three-dimensional mesh structure increases the flexural strength from 1.5 MPa to 8-10 MPa, tile backer boards less susceptible to dents or cracks in the event of impact.

Tile backer boards provides excellent seismic resistance, isolating stress from cracks in the underlying base layer and reducing the risk of cracking in the finish layer due to deformation and vibration. Understanding its seismic resistance principle allows for better application. The backing uses a flexible buffer layer to absorb stress from cracks in the base layer, thereby reducing the energy transferred to the finish layer. The closed-cell structure of the XPS sheet maintains stability in vibrating environments, preventing the backing from cracking.

High-rise buildings experience micro-swaying when subjected to wind, known as wind vibration. Furthermore, building structures experience thermal expansion and contraction with temperature fluctuations, which can cause stress in the base layer and lead to cracking. Choosing tile backer boards reduces the cracking rate from 18% to 1.2%, thereby reducing subsequent maintenance costs.

In areas prone to earthquakes, even minor vibrations in the base layer can weaken the bond between tile adhesive and the base layer, leading to hollowing and tile loss. Choosing the right tile backing ensures strong adhesion between the backing and tile adhesive, ensuring a secure hold even under vibration. Users reported that after a magnitude 4 earthquake, the hollowing rate of the tiles was less than 2%, and they were very satisfied with the results.

The tile backer boards are made of brand-new materials during production, strictly controlling the use of hazardous substances. Volatile organic compounds (VOCs) like formaldehyde meet industry standards, making them suitable for homes with high air quality requirements, especially those in schools and hospitals.

The low-toxicity of the tile backer boards is not the result of a single effort; rather, rigorous control is applied at every step, from raw material procurement to production and processing to finished product testing. The XPS core material is made from "zero formaldehyde, low VOC" raw materials, with only environmentally friendly foaming agents added. The polymerized nano-quartz coating uses a water-based resin instead of a solvent-based resin, with a VOC content of ≤100g/L and no heavy metals. Clean processing is used during production to reduce pollution, and low-temperature screw extrusion technology prevents the excessive decomposition of the resin at high temperatures, which can produce volatile compounds like styrene and formaldehyde.

Homes have high expectations for the long-term safety of their indoor air, and the advantage of tile backer boards lies in their lack of "hidden pollution" risks, making them suitable for children and the elderly.
