Main Raw materials

Natural mineral fibers (chrysotile, crocidolite, etc.)

Artificial synthetic ceramic fibers (such as aluminum silicate, etc.)

Safety

Highly dangerous (Strong carcinogen, inhaling dust can cause asbestosis and lung cancer)

Safe and environmentally friendly (non-toxic, harmless, and no carcinogenic risk)

Long-term using temp

Approx  550°C - 700°C (Later, It will become powderize and brittle)

Approx 1000°C - 1200°C( Using Temp depends on the model)

Short-term temp

Approx 800°C - 1000°C

Min 1260°C

Chemical resistance

Strong alkali resistance, but poor acid resistance

Excellent acid and alkali resistance and resist to most chemical corrosion

Physical resistance

The fibers are brittle and have lower strength

The fibers have good flexibility, high tensile strength and strong thermal shock resistance

Main application

Historical use for insulation and fire prevention (now banned/phased out)

Industrial heat insulation, sealing, fireproof curtains, welding protection, automotive heat insulation

The environmental protection

It remains an environmental hazard after being discarded (requiring hazardous waste treatment).

Environmentally friendly materials have a small impact on the environment after being discarded
