When constructing insulation projects in areas with potentially explosive gases, vapors, mists, or dust, materials typically need to meet ATEX requirements. This text will discuss which materials used to make removable insulation blankets/jackets can meet ATEX ZONE standards.
What is ATEX Zone?
The term “ATEX zone” refers to areas where explosive atmospheres may occur. The name ATEX is derived from the French title of the 94/9/EC directive: “Appareils destinés à être utilisés en ATmosphères EXplosibles”. This European Union directive is aimed at improving the safety and health protection of workers potentially at risk from explosive atmospheres. It classifies hazardous areas into different zones based on the frequency and duration of the presence of an explosive mixture:
- Zone 0 (for gases): An area in which an explosive gas atmosphere is present continuously or for long periods.
- Zone 1 (for gases): An area in which an explosive gas atmosphere is likely to occur occasionally in normal operation.
- Zone 2 (for gases): An area in which an explosive gas atmosphere is not likely to occur in normal operation and, if it occurs, will exist for a short period.
- Zone 20 (for dusts): Similar to Zone 0 but concerning combustible dust.
- Zone 21 (for dusts): Similar to Zone 1 but concerning combustible dust.
- Zone 22 (for dusts): Similar to Zone 2 but concerning combustible dust.
What Are The Materials for Removable Insulation Blankets in ATEX zone?
When selecting materials for removable insulation blankets used in ATEX zones, consider the following factors:
Explosion Resistance: Materials must comply with ATEX directives to ensure safety in potentially explosive environments. Temperature Resistance: They should withstand high temperatures in the working environment. Chemical Resistance: Materials need to resist chemical corrosion, especially in environments where they may come into contact with chemicals. Durability: They should have a long lifespan, resisting wear and tear. Flexibility: Materials should be easy to install and remove for maintenance. Fire Resistance: They must be fire-resistant to minimize fire risk. Weight: Materials should be lightweight for ease of handling and installation. Water Resistance: In humid environments, they should be waterproof. Acoustic Performance: Materials should have sound absorption capabilities if noise control is required. Cost-Effectiveness: Choose materials that are economical while meeting all technical requirements. Ensuring compliance with all relevant safety standards and regulations is crucial.
The following products all meet the above requirements and are widely used in ATEX ZONE areas.
Anti-static PTFE Coated Fiberglass Fabric (Suntex-8001X)
Anti-static PTFE fiberglass fabric is ideal for removable insulation blankets in ATEX zones due to its unique properties. It effectively dissipates static electricity, reducing ignition risks in explosive atmospheres. This fabric combines the durability and heat resistance of fiberglass with PTFE’s chemical stability and non-flammability. Its anti-static feature prevents sparks, crucial in environments laden with flammable gases or dust. Moreover, it maintains flexibility and thermal insulation efficiency, ensuring safety and performance in demanding conditions. Thus, it meets the stringent requirements for use in hazardous locations.
Suntex offers anti-static PTFE coated fiberglass fabric, with a thickness of 0.4mm, available in single-sided and double-sided coatings.
Anti-static Silicone Coated Fiberglass Fabric (Suntex-1288)
Anti-static silicone fiberglass fabric is suitable for removable insulation blankets due to its ability to effectively dissipate static electricity, minimizing ignition risks in explosive atmospheres. It combines thermal resistance and flexibility, ensuring reliable performance under extreme conditions while preventing static build-up. This makes it safe for use in ATEX zones, offering necessary insulation without compromising safety or durability. Additionally, anti-static silicone coated fiberglass fabric has a cost advantage over anti-static PTFE fiberglass fabric, making it a more economical choice without sacrificing quality or effectiveness. Its robustness against heat, chemicals, and physical stress further ensures long-lasting protection in demanding industrial settings.
Suntex offers anti-static Silicone coated fiberglass fabric, with a thickness of 0.4mm, available in single-sided and double-sided coatings.
Below sheet is the difference between the two fabrics.
| Feature/Aspect | Anti-static PTFE Fiberglass Fabric | Anti-static Silicone Fiberglass Fabric |
|---|---|---|
| Thermal Resistance | Excellent thermal stability across a wide range. | Good thermal resistance, suitable for many applications. |
| Chemical Resistance | Superior chemical resistance, especially against corrosive substances. | Good chemical resistance but may not match PTFE’s level. |
| Anti-static Properties | Effective in dissipating static electricity to prevent ignition risks. | Effective in dissipating static electricity to prevent ignition risks. |
| Flexibility and Durability | Good flexibility and durability | High flexibility and durability |
| Cost | Generally more expensive due to advanced properties. | More cost-effective compared to PTFE alternatives. |
| Application Suitability | Ideal for extreme environments with high chemical exposure. | Suitable for a broad range of applications, especially where cost is a concern. |
| Non-flammability | non-flammable, enhancing safety in explosive atmospheres. | non-flammable, enhancing safety in explosive atmospheres. |
| Environmental Resistance | Resistant to UV light, water, and most chemicals. | Good resistance to environmental factors but can degrade faster under UV light compared to PTFE. |
