The Phomi MCM strip stone wall cladding panel made of RL-EOSD modified clay has A-level fire resistance, waterproofing, and resistance to atmospheric environments for more than 20 years. It is lightweight, stable in performance, easy to install, widely used in more than 40 countries or regions around the world, and is a low-carbon and environmentally friendly building exterior wall Phomi MCM strip stone wall cladding panel. These characteristics can be supported by multiple pieces of evidence. Firstly, the RL-EOSD Phomi MCM strip stone wall cladding panel has Class A fire resistance performance. According to, the insulation Phomi MCM strip stone wall cladding panel is divided into A1 level fire-resistant and B1 level flame-retardant types, among which A1 level fire-resistant materials fully meet the increasingly strict requirements for fire-resistant design and use. In addition, it was mentioned that Guochuang Bafuli's new A-grade fireproof insulation material has true non combustible characteristics and meets green environmental protection requirements. This indicates that the modified clay Phomi MCM strip stone wall cladding panel has reached the national A-level standard in terms of fire resistance performance. Secondly, the RL-EOSD Phomi MCM strip stone wall cladding panel has waterproof performance. It is mentioned that the product has strong waterproof performance, with a moisture content of only 5%. It is also pointed out that the exterior wall Phomi MCM strip stone wall cladding panel has waterproof and anti mold functions, and is suitable for various building environments. These pieces of information indicate that the modified clay Phomi MCM strip stone wall cladding panel exhibits excellent waterproof performance. Thirdly, the Phomi MCM strip stone wall cladding panel has been used in atmospheric environments for over 20 years. It is mentioned that polyester topcoat is coated on aluminum zinc alloy steel plate using baking paint technology, and it will not fade for 10-15 years when used outdoors, with a service life of over 45 years. This indicates that the Phomi MCM strip stone wall cladding panel has significant advantages in weather resistance and service life.
