Release Time: 2025-09-28

In fields such as aerospace, high-end kilns, and industrial high-temperature equipment, where stringent requirements are placed on thermal insulation and safety performance, the quality of materials directly determines the stability and efficiency of projects. Rosewool Insulation Refractory Co.,Ltd, a seasoned manufacturer with over a decade of expertise in thermal insulation and refractory materials, has emerged as a preferred brand in aerospace-grade material applications. Through its independently developed coke-bonded ceramic fiber blankets, the company offers six core advantages: "white appearance, high-temperature resistance up to 1430°C, thermal insulation, fire resistance, heat insulation, and soundproofing and vibration resistance." These features provide reliable thermal insulation solutions for various high-precision and advanced engineering projects.

Rosewool has emerged as a standout in the fiercely competitive market, thanks to its comprehensive and robust capabilities. In terms of technological R&D, the company has assembled a research team led by materials science experts and aerospace insulation technology consultants, consistently focusing on industry technical challenges and market demands. For the performance optimization of cokesite ceramic fiber blankets, the team conducted hundreds of formula adjustments and process iterations. By innovatively using high-purity cokesite as the core raw material, combined with advanced centrifugal blow-molding and high-temperature sintering technologies, they overcame the industry-wide challenge of "high-temperature resistance leading to brittleness, and flexibility compromising thermal resistance." This breakthrough enables the product to achieve both exceptional heat resistance and outstanding flexibility.

In the production and quality control processes, the company has established a stringent standard system. With a modern production base covering nearly 20,000 square meters, it is equipped with five dedicated production lines for ceramic fiber blankets made from coke-bonded graphite. Utilizing advanced equipment such as automated material mixing, precise temperature-controlled firing, and intelligent cutting, the company achieves fully standardized production from raw materials to finished products, with an annual capacity of 1.5 million square meters. This enables it to meet the bulk procurement demands of large aerospace projects and industrial furnace projects while also responding swiftly to urgent orders to ensure timely delivery. Additionally, the company has introduced internationally advanced testing equipment, where every batch of products undergoes rigorous inspection across 12 criteria, including high-temperature resistance, thermal conductivity, and tensile strength. This ensures that all products leaving the factory 100% comply with aerospace-grade material standards, preventing any substandard products from entering the market.

The ceramic fiber blanket from Rosewool, made from coking basalt, has become a representative of aerospace-grade thermal insulation materials, with its product advantages fully meeting the demands of high-end applications. First, its high-temperature resistance of 1,430°C and exceptional thermal insulation are its core highlights. The product uses high-purity coking basalt as raw material, processed through specialized techniques, enabling long-term stable operation in high-temperature environments up to 1,430°C without softening, deformation, or shedding—far exceeding the 1,260°C thermal limit of ordinary ceramic fiber blankets. Additionally, the porous mesh structure formed within the fibers reduces thermal conductivity to as low as 0.03 W/(m·K), effectively blocking heat transfer. In applications such as aerospace engine compartments and industrial high-temperature kilns, it can reduce heat loss by over 40%, significantly helping enterprises cut energy consumption costs.

Secondly, the product combines a pristine white appearance with fire-resistant safety. Its pure and clean exterior makes it suitable for highly demanding cleanliness fields such as aerospace manufacturing, food processing, and pharmaceutical production, avoiding issues like slagging and dust pollution common with traditional ceramic fiber materials. Additionally, the product meets the national Class A non-combustible standard, remaining flame-retardant and free from toxic or harmful gas emissions when exposed to fire. It effectively blocks flame spread in high-temperature environments, providing a robust defense line for the safe operation of aerospace equipment and industrial facilities.

Moreover, the excellent sound absorption and shockproof performance further expand the product's application scope. The ceramic fiber blanket made of coking clay, through its unique porous structure formed by intertwined fibers, effectively absorbs high-frequency noise generated during equipment operation, reducing noise levels by 25-30 decibels and significantly improving the working environment. Simultaneously, the fibers themselves possess good flexibility and tensile strength, enabling them to withstand minor vibrations and impacts during aerospace launches and equipment operation. This prevents insulation layer cracking and detachment caused by vibrations, extends the material's service life, and reduces maintenance and replacement costs

In addition, the product boasts advantages of being lightweight and easy to install. With a density only 1/10 that of traditional refractory bricks, it significantly reduces the load-bearing burden on aerospace equipment and kiln furnace walls. Moreover, its flexible material allows for arbitrary bending and cutting, enabling rapid installation of complex shapes. Compared to traditional refractory materials, construction efficiency is improved by over 60%, effectively shortening project timelines.

Today, the ceramic fiber blankets made of bauxite from Rosewool have been widely used in aerospace component heat treatment furnaces, equipment insulation for satellite launch bases, large industrial high-temperature kilns, and building fireproof isolation zones. They provide thermal insulation support for multiple national key projects and have earned high recognition from clients such as aerospace technology companies and major steel enterprises
