PE6828 Refractory Fibre (RCF)

Refractory Ceramic Fibre Description

Refractory Ceramic Fibres (RCF) are synthetic vitreous fibres (SVF). They consist mainly of alumina (Al₂O₃) and silicon dioxide (SiO₂). The fibres are produced by melting and then blowing or spinning a precise 50:50 weight mixture of oxides. RCF exhibits low thermal conductivity, restrained heat accumulation and resistance to thermal shock and chemical corrosion. It is low in mass, permits easy installation and maintains stability at elevated temperatures.

High-purity grades of RCF may withstand maximum temperatures of up to 1 260°C and continuous operating temperatures of up to 1 180°C. Consequently, the material is utilised in industrial thermal insulation, marine insulation and high-temperature processing. Following the phase-out of asbestos materials worldwide, RCF is deployed to address thermal protection requirements.

Refractory Fibre Applications

·       Furnace and Kiln Insulation – The material is used as a lining in high-temperature industrial equipment.

·       Fire Protection – It is applied in blankets, curtains and building safety installations.

·       Marine Insulation – It is used in engine rooms and exhaust systems on ships.

·       Aerospace Heat Shields – It is employed in aircraft and spacecraft for thermal protection.

·       Automotive Heat Insulation – It is applied to exhaust components and engine parts.

·       Power Plant Insulation – It is utilised in turbines, ducts and reactors.

·       Household Appliances – Ovens, heaters and dryers incorporate the material.

·       Sealing and Gasket Material – The material fills gaps and seals areas exposed to high heat.

·       Lab Equipment – It is used for lining high-temperature test chambers.

Refractory Fibre FAQs

Q1: What is Refractory Ceramic Fibre (RCF)?
A: RCF is a synthetic fibre produced from a blend of alumina (Al₂O₃) and silica (SiO₂). It is designed for high-temperature insulation and may tolerate temperatures up to 1 260°C.

Q2: What are the key properties of RCF?
A: RCF displays low thermal conductivity, resistance to thermal shock, restrained heat accumulation, chemical stability and durability at elevated temperatures.

Q3: What industries use RCF?
A: It is employed in metallurgy, ceramics, petrochemicals, aerospace, power generation, marine applications and industrial furnace insulation.

Regulatory Compliance:

RCF is not currently prohibited but is subject to strict regulation. Employers must comply with safety standards such as:

COSHH Regulations (1994)

COSHH Carcinogens ACOP

REACH (EU Regulation for Registration, Evaluation, Authorisation, and Restriction of Chemicals)

Exposure Control:

According to occupational guidelines, exposure limits for synthetic vitreous fibres, including RCF, are 5 mg/m³ (8-hour TWA) and 2 fibres/ml (8-hour TWA). Employers must assess exposure and implement control measures so that these limits are not exceeded.

Substitution Priority:

The use of RCF should be avoided where possible. Given that less hazardous alternatives are available in line with the COSHH Carcinogens ACOP, substitution is recommended. Where substitution is not feasible, full risk control measures must be implemented.

Personal Protective Equipment (PPE):

Respirators, protective clothing and gloves must be used when handling RCF. Consequently, dust containment systems and local exhaust ventilation should be installed to prevent airborne fibre release.

Worker Training and Monitoring:

Training on potential risks and proper handling procedures must be provided. Regular health monitoring and workplace air quality assessments are required.

Safe Disposal:

RCF waste must be treated as hazardous material and disposed of in accordance with local disposal regulations.

SVHC Classification:

On 18/06/2012, the European Chemicals Agency (ECHA) added Alumino-Silicate RCF (Al-RCF) and Zirconia-Alumino-Silicate RCF (ZrAl-RCF) to the Substances of Very High Concern (SVHC) list due to suspected carcinogenicity. Usage and marketing of these materials within the EU are now subject to REACH controls.
