Technology leader in the production of nonlinear optical crystals, piezoelectric crystals, optical window crystals, and related materials, with two First Prizes of State Scientific and Technological Progress Awards.

Key materials provider for major national projects and large scientific facilities such as Shenzhou spacecraft, Micius satellite for quantum science experiments and Experimental Advanced Superconducting Tokamak (EAST), supporting the development of high-tech industries including lasers, new materials, semiconductors, and aerospace.

We are one of the early pioneers in developing both wet synchronous and asynchronous stretching technologies. Our products cover 3-12 μm wet separators and various coated separators. We built the world's first 4 × 50 wet bidirectional synchronous stretching production line. These products are widely used in fields such as electric vehicle batteries, 3C consumer batteries, energy storage batteries, etc.

Air Filtration Membrane: We have developed technology and advanced industrialization equipment for membrane materials with multiple independent intellectual property rights, for which we have won the First Prize of State Scientific and Technological Progress Award and China Patent Gold Award.

Our products cover environmental protection filtration, purification filtration, energy battery materials, and functional organic membrane materials. These products are widely used in fields such as building materials, metallurgy, power, and chemicals, and are sold to Europe, America, Asia Pacific, the Middle East, and other regions.

We own multiple brands including BNBM, YUWANG, SHUYANG, JINMUZHI, OTAI, YUEHUANG, SAITE, YUANDA HONGYU, etc.

Our products cover more than 100 varieties in 5 categories, including self-adhesive waterproofing membranes, polymer-modified asphalt waterproofing membranes, polymer waterproofing membranes, waterproof coatings, as well as waterproofing and anti-seepage auxiliary materials (supporting products and flooring materials).

We are deeply involved in engineering and construction markets, providing one-stop system solutions widely used in various fields including infrastructure construction, residential and commercial properties, and modern industrial buildings for both construction and renovation, delivering comprehensive, user-oriented solutions.

Our well-known brands of coatings include Loong Brand, Carpoly, Beacon, and Great Bridge.

Architectural coatings are used in fields such as interior and exterior wall coatings, wood coatings, floor coatings, external wall insulation, artistic coatings, waterproof coatings, decorative stone coatings, auxiliary decorative materials, inks, and coating services.

Industrial coatings are applied in fields including industrial anti-corrosion, aerospace, marine anti-corrosion, wind turbine blades, new energy, and engineering & agricultural machinery, etc.

BNBM powder coatings are 100% solids, solvent-free, and feature zero VOC emissions. As 4E coatings, the products are widely applied in photovoltaics, new energy, automotive, and engineering machinery sectors.

We provide fused cast refractories, sintering and non-sintering refractories, monolithic refractories and various special wear- and heat-resistance materials.

We have built 5 national-level green factories and the industry's first transparent factory digitally visualized manufacturing facility.

CNBM's raw material-grade graphite powder covers a full range of product specifications and is exported to more than 30 countries and regions including Japan, the United States, Germany, the United Kingdom, and Southeast Asia.

Material-grade products such as spherical graphite, high-purity graphite, and natural graphite anode materials are widely used in fields such as new energy, semiconductors, and aerospace technology.
