Polysilazane precursor​

ZhengZhou Quartz Master New Materials Co., Ltd. is dedicated to the development and application of polymer-derived ceramic precursor resins. High-performance polymer-derived ceramic precursor resins are one of the key raw materials blocked by foreign countries from China.

In recent years, they have shown tremendous application potential in numerous high-end fields, including petrochemicals, aerospace, marine engineering, photovoltaic cells, porous ceramics, high-temperature resistant coatings, ceramic fibers, and ceramic-based composites.

The company is currently collaborating with Sinopec, PetroChina, and other companies to develop products for applications in the petrochemical industry, including high-temperature resistance, erosion resistance, corrosion resistance, and anti-coking.

Polymer-derived ceramic precursors

Polymer-derived ceramic precursors are a class of organic polymer materials with unique properties and broad application prospects. Their backbones are composed of repeating -5i-N- units, with molecular weights (Mw) > 200,000 g/mol. Their exceptional solubility and meltability offer significant advantages in various processing techniques. Notably, they spontaneously crosslink at high temperatures, transforming into stable inorganic silicon-nitrogen-carbon or silicon-nitrogen ceramics. This characteristic imparts remarkable thermal stability and exceptional chemical inertness.

• Special Properties: Can be converted into a ceramic at high temperatures, with a temperature resistance exceeding 1350°C.
• High-Temperature Resistance: Ultra-long corrosion and oxidation resistance.
• Low Density: Suitable for lightweight material needs.
• Versatile Processability: ① Dissolvable, can be combined with nanopowders to create high-performance coating materials;
  ② Meltable, can be combined with various fibers to create high-performance structural materials.

Key Applications:

• Ceramic Precursors: Preparation of high-performance ceramic fibers and ceramic coatings.
• Microelectronics Packaging: Insulating passivation layers, providing high dielectric strength and improving device reliability.
• Composite Prepregs: Excellent binder for high-temperature-resistant fiber materials.
• Thermal Barrier Coatings: Ultra-high-temperature-resistant, anti-graffiti, and easy-to-clean materials.

High temperature resistant polymer derived ceramic precursor plastics

This product utilizes our company’s independently developed polymer-derived ceramic precursor resin as a matrix, incorporating high-temperature-resistant active fillers, reinforcing fibers, additives, and auxiliaries. This high-temperature-resistant polymer-derived ceramic precursor plastic exhibits excellent thermochemical stability and thermodynamic properties. The synergistic use of high-temperature active fillers and reinforcing fibers ensures mechanical strength at varying temperatures.

This new plastic is dense, waterproof, and resistant to high temperatures, acid, alkali, and salt spray corrosion, aging, and wear. It addresses the issues of traditional plastics with low mechanical strength and susceptibility to corrosion and oxidation in high-temperature environments.

Key Features:

• After curing, it undergoes high-temperature pyrolysis to form a ceramic composite material with ultra-high temperature resistance (1500°C).
• Ultra-high salt spray resistance, with a duration of up to 3500 hours.
• Excellent acid and alkali corrosion resistance.
• Excellent water and oil resistance.
• • High strength even in high-temperature environments.

Designed Applications:

Can be used in aerospace high-temperature composite structural materials, electronic packaging materials, semiconductor packaging materials, high-temperature corrosion-resistant structural components, and high-temperature combustion chamber interiors to protect against oxidative corrosion. New energy vehicle battery packs with high-temperature corrosion resistance are also used. They can also be used in the nuclear power, hydrogen fuel, energy, petrochemical, marine engineering, automotive, metallurgical, and other manufacturing industries. They can also be used for high-temperature special switchgear and socket strips, and for heavy-duty corrosion and oxidation protection of offshore platform structures.
