When it comes to industrial-grade high-temperature insulation, Quartz Wool & Felt are standout solutions crafted by Technical Glass Products. These materials are made from pure fused quartz (SiO₂), offering unmatched performance in extreme environments.
What Are Quartz Wool & Felt?
Quartz Wool is a non-woven assembly of extremely fine fused quartz fibers—often referred to as fused quartz wool or felt. These fibers are non-combustible, chemically inert, and derived directly from pure quartz glass.
While Quartz Wool is commonly sold in loose form, Quartz Felt refers to the same fibrous material produced in mats, pads, or sheets—ideal for structured insulation uses.
Key Properties
- Exceptionally Heat‑Resistant: With melting points exceeding 1,660 °C and thermal stability to 1,710 °C, quartz wool and felt maintain structural integrity in ultra‑hot processes.
- Low Thermal Expansion: The material’s coefficient of thermal expansion is extremely low, minimizing stress and cracking during rapid temperature changes.
- Chemical & UV Resistance: Being pure SiO₂, it’s resistant to most acids, solvents, and UV exposure.
- High Purity & Mechanical Performance: Mechanical strength and insulation properties make quartz wool ideal for both furnace linings and delicate filtration setups.
Applications of Quartz Wool & Felt
1. Industrial & Laboratory Furnaces
Use quartz wool and felt to line furnace chambers, kiln interiors, and heating elements. Their high-temperature capabilities and insulating performance help maintain process efficiency and protect structural components.
2. Thermal Insulation
As insulation packs, seals, gaskets, and pipe wraps, these materials help reduce heat loss in thermal processing, glass-melting, or petrochemical equipment.
3. Filtration & Catalyst Supports
Fine quartz fibers act as inert, thermally stable filtration media or substrate for catalytic coatings—ideal for high-temperature chemical processes.
4. High Purity & Optics-Based Research
Quartz wool and felt are well-suited for semiconductor manufacturing, UV-transparent applications, and laboratory experiments needing high chemical purity and thermal resilience.
