Glass fiber is mostly silicon dioxide, which is harmless to human body. But it can't be decomposed in the human body. It is no problem to rinse thoroughly after wiping the pot with it, otherwise the silicon dioxide residue will easily enter the appendix after entering the human body, causing inflammation.

Contact dermatitis often occurs in glass fiber workers, but some workers can gradually tolerate it, which is called "hardening phenomenon".

The degree of damage to skin varies according to fiber diameter and surface roughness. At present, it is recognized that the fiber diameter is more than 5μm, which has obvious stimulating effect. A few workers exposed to glass fibers and rock wool have skin allergies, but it has not been proved that these fibers are allergens themselves.

Raw material of glass fiber and its application;

Compared with organic fiber, glass fiber has higher temperature resistance, incombustibility, corrosion resistance, good heat and sound insulation, high tensile strength and good electrical insulation. But it is fragile and has poor wear resistance.

The glass fib used for manufacture reinforced plastics or rubber as reinforce materials has that following characteristics, which make the use of glass fiber far exceed other kinds of fibers, and its development speed is far ahead. These features are as follows:

1, high tensile strength and low elongation (3%).

2. High elastic coefficient and good rigidity.

3. It has large elongation and high tensile strength within the elastic limit, so it absorbs large impact energy.

4. It is an inorganic fiber with incombustibility and good chemical resistance.

5, the water absorption is small.

6. Good dimensional stability and heat resistance.
