Understanding Halogen-Free Cable Compounds
Halogen-free cable compounds are materials used for insulation and sheathing that do not contain halogen elements such as chlorine or bromine. This feature makes them more environmentally friendly and safer in case of fire, as they typically emit less toxic smoke and corrosive gases. However, there are several factors to consider when choosing the appropriate compounds.
Key Properties of Halogen-Free Compounds
Flame Retardancy:
- Look for compounds with well-established flame-retardant properties.
- Review certifications and tests (e.g., UL 94) showcasing their performance in fire situations.
Mechanical Strength:
- The compound should have high resistance to wear and tear.
- Consider factors like tensile strength, elasticity, and tear resistance, especially in applications with high movement.
Thermal Stability:
- Ensure that the compound can withstand high temperatures without degrading.
- Investigate the thermal aging properties to ensure long-lasting performance.
Chemical Resistance:
- Identify the environment where the cables will be installed.
- Select compounds that can resist chemicals, UV exposure, and moisture.
Application-Specific Considerations
Selecting halogen-free cable compounds can vary depending on the specific application. The following are specific applications and the relevant considerations for each:
Industrial Automation:
- Choose compounds with high flexibility and abrasion resistance to accommodate constant movement.
Construction:
