Extreme temperature protection for the most demanding industrial applications
RONDY high silica cloth represents the pinnacle of thermal protection technology, engineered to withstand extreme temperatures while maintaining exceptional flexibility and durability
RONDY high silica cloth is woven from premium silica fibers containing over 96% SiO2, creating a material that can withstand continuous temperatures up to 1000°C (1832°F) and intermittent exposure up to 1800°C (3272°F).
Unlike traditional fiberglass products, RONDY high silica cloth offers superior thermal stability, significantly lower thermal conductivity, and exceptional resistance to chemical attack, making it the ideal choice for the most demanding high-temperature applications


Exceptional Temperature Resistance Withstands continuous exposure up to 1800°F (982°C) and short-term surges up to 2700°F (1482°C) . Our High Silica Cloth remains flexible and structurally intact where other materials would fail, providing reliable protection in critical situations.
Excellent Thermal Insulation Its low thermal conductivity effectively contains heat, protecting personnel and equipment. This makes it an ideal choice for welding curtains, fire blankets, furnace curtains, and high-temperature gasketing.
Non-Asbestos & Environmentally Safe Composed of high-purity silica, our cloth is completely asbestos-free and emits no harmful smoke or odors when exposed to high temperatures, ensuring a safer workplace.
Outstanding Chemical Resistance Highly resistant to most corrosive chemicals, acids, and molten metals. It will not dissolve or deteriorate when exposed to most industrial compounds, ensuring long-lasting performance.
High Tensile Strength & Durability Despite its soft and pliable hand feel, the cloth possesses high tensile and tear strength, offering excellent durability and abrasion resistance for long service life in tough industrial settings.
Low Thermal Shrinkage Maintains its shape and dimensions even under prolonged exposure to high heat, ensuring consistent coverage and protection without becoming brittle.
