The main differences between LSZH (Low Smoke Halogen-Free) and PVC (Polyvinyl Chloride) lie in their combustion characteristics, environmental friendliness, cost, and flexibility. LSZH produces very little smoke and harmless white smoke when burning, while PVC releases toxic black smoke and corrosive gases. Therefore, LSZH is more suitable for applications with strict safety and environmental requirements. Although it is more expensive and slightly less flexible, PVC is more cost-effective and offers better flexibility.
LSZH (Low Smoke Halogen-Free)
Combustion Characteristics: Releases very little smoke when exposed to fire, halogen-free, and produces white smoke upon combustion.
Environmental Friendliness: Halogen-free, does not produce toxic or corrosive gases, and is safer for humans and the environment.
Applications: Suitable for public places with high safety and environmental requirements, such as subways, airports, hospitals, and areas containing sensitive electronic equipment.
Flexibility: Relatively low, unsuitable for applications requiring continuous bending, such as robotics.
Cost: More expensive than PVC. PVC (Polyvinyl Chloride)
Combustion Characteristics: Produces large amounts of dense black smoke and corrosive acidic gases when burning, resulting in low visibility.
Environmental Impact: Contains chlorine, releasing toxic and harmful gases upon combustion.
Applications: Widely used in general construction, household wiring, and other fields, offering cost-effectiveness.
Flexibility: Relatively soft, easy to install and handle.
Cost: Relatively low price.
