Ceramic fiber rope is manufactured in three construction types — twisted, round braided, and square braided — each delivering a distinct combination of density, flexibility, and gas-tight sealing performance. The construction method determines fiber orientation, density, compressive behavior, and ultimately whether the rope can hold a high-pressure furnace seal or only serve as passive thermal fill. This guide explains how each type is made, how it performs, and how to select the correct one for your groove geometry and operating conditions.
Aluminum silicate fiber board is a rigid, high-density refractory insulation panel vacuum-formed from high-purity alumina-silicate fibers (also known as ceramic fiber board or alumina fiber board). The fibers are bonded with an inorganic binder and pressed into flat boards with bulk densities of 260–320 kg/m³, providing high compressive strength, low thermal conductivity (≤0.12 W/(m·K) at 600°C), and continuous service temperatures from 1000°C to 1400°C depending on Al₂O₃ content. It is widely used as a structural ceramic fiber board alternative to traditional refractory bricks in furnace linings, burner blocks, and hot-face insulation. Reference Price: USD 2.00 – 15.00 / kg (varies by grade, density, and order volume)

Power plants face critical pain points with waste heat boiler pipes: irregular shapes make insulation hard to fit, and high temperatures (800–1200℃) cause excessive heat loss, cutting energy efficiency. Highland Refractory’s Ceramic Fiber Products solve this—flexible ceramic fiber blankets (1260℃ grade, thermal conductivity ≤0.12 W/(m·K)) conform tightly to curved pipes, eliminating air gaps that leak heat. Ceramic blanket insulation, with its lightweight design (1/10 the weight of bricks), simplifies installation without straining pipe structures. These products reduce heat loss by 35%, boosting boiler efficiency and lowering fuel costs, making them ideal for power plants prioritizing energy savings and easy maintenance.
Industrial and commercial chimneys struggle with two key issues: high-temperature corrosion (from flue gases) and insulation that peels or degrades, leading to heat loss and structural damage. Highland’s ceramic fiber insulation—including dense ceramic fiber blankets (1430℃ grade, tensile strength ≥0.08 MPa)—resists corrosion and thermal shock, withstanding 1100℃ quenching cycles 50+ times. Unlike rigid alternatives, it seals chimney joints tightly, reducing heat loss by 30% and preventing condensation that accelerates rust. This durability extends chimney lifespan by 5+ years, cutting replacement costs for facilities like factories and commercial heating systems.
Furnaces, boilers, and heaters demand linings that handle extreme heat (1200–1600℃) and frequent thermal cycles without cracking—traditional bricks fail here, causing unplanned downtime. Highland’s Ceramic Fiber Products excel: 1430℃ ceramic fiber blankets line boiler fireboxes, offering quick heat-up and cool-down, while 1600℃ ZrO₂-reinforced ceramic fiber insulation lines high-temperature furnaces (e.g., metallurgy). These products are easy to cut and install, reducing lining replacement time by 50%. Their low thermal conductivity also lowers energy use, making them a reliable choice for industries like metalworking and chemical processing.
Kilns and furnaces need backup linings that are easy to store, quick to install, and compatible with existing structures—generic linings often misfit, causing costly production delays. Highland’s pre-cut ceramic fiber blankets (1260–1430℃ grades) and modular ceramic blanket insulation are tailored to common kiln/furnace sizes, ready for immediate use. They bond seamlessly with primary linings, providing temporary heat resistance during emergency repairs or scheduled maintenance. Lightweight and compact, they save storage space, while their durability ensures consistent performance—keeping facilities like ceramic or glass factories operational with minimal downtime.
