Why do European and American markets require the use of halogen-free and low-smoke cable sheath materials?- Hangzhou Meilin New Materials Technology Co., Ltd.

The European and American markets require the use of halogen-free and low-smoke cable sheath materials, mainly based on the following new safety standards:

ML-H9001B1 90℃ Halogen-Free Low Smoke Flame Retardant Class B1 Sheath Compound

1. Environmental protection and human health protection

Halogen-free requirements:
Halogen hazards: Traditional cable sheath materials often contain halogens (such as fluorine, chlorine, bromine, iodine, and astatine). These elements release toxic gases such as dioxins when they are at high temperatures or burn, which cause great harm to human health and the environment.
Halogen-free advantages: Halogen-free and low-smoke cable sheath materials do not contain halogens and do not produce toxic gases when burned, which effectively reduces the risk of poisoning during fires and protects human health.
Low smoke characteristics:
Smoke hazards: The smoke generated when the cable burns will seriously affect the evacuation and rescue of personnel, and increase casualties and losses in fires.
Low smoke advantages: The amount of smoke generated when the halogen-free and low-smoke cable sheath materials burns is very small, and the smoke concentration is low and the light transmittance is high, which provides better conditions for personnel evacuation and fire rescue.

2. Improved fire safety performance

Flame retardant performance:
Flame retardant requirements: The European and American markets have strict requirements on the flame retardant performance of cables. Halogen-free low-smoke cable sheath materials usually have good flame retardant properties and can effectively delay the spread of fire when a fire occurs.
Flame retardant advantages: By adding flame retardants or using flame retardant materials, halogen-free low-smoke cable sheath materials can form a carbonized layer when burning, preventing the further spread of flames and heat, and improving the fire safety performance of cables.
Self-extinguishing:
Self-extinguishing requirements: The cable should be able to extinguish itself after leaving the fire source to prevent the fire from rekindling.
Self-extinguishing advantages: Halogen-free low-smoke cable sheath materials usually have self-extinguishing properties and can be extinguished quickly after the fire source is removed, reducing the risk of fire rekindling.

3. Comply with international standards and regulatory requirements

International standards:
The European and American markets generally follow the cable safety standards formulated by the International Electrotechnical Commission (IEC) and others. These standards have clear requirements for the environmental protection, flame retardancy, low smoke and other properties of cables.
Halogen-free low-smoke cable sheath materials comply with these international standards and can meet the requirements of the European and American markets for cable safety performance.
Regulatory requirements:
Governments in Europe and the United States have issued relevant regulations to restrict or prohibit the use of cable materials containing halogen in public places, building facilities, etc.
The use of halogen-free low-smoke cable sheath materials is a necessary measure to meet these regulatory requirements, which helps companies avoid legal risks and market access barriers.

4. Market trends and sustainable development

Market trends:
With the improvement of environmental awareness and the popularization of the concept of sustainable development, halogen-free low-smoke cable sheath materials have become the mainstream trend in the cable industry.
As an important area for cable consumption, the European and American markets continue to grow in demand for halogen-free low-smoke cable sheath materials.
Sustainable development:
The use of halogen-free low-smoke cable sheath materials helps reduce environmental pollution during cable production and use, and meets the requirements of sustainable development.
The use of halogen-free low-smoke cable sheath materials by enterprises can not only help improve product competitiveness, but also establish a good corporate image and win the trust and support of consumers.
