Fiberglass is harmful to people.
The material component of most fiberglass is silica, which itself is not toxic to humans. But it cannot be broken down in the human body. There is no problem with rinsing thoroughly after wiping the pan with it, otherwise silica residue can easily enter the appendix after entering the human body, triggering inflammation.
Contact dermatitis occurs more often in fiberglass workers, but some workers can gradually tolerate, known as "hardening phenomenon.
The degree of damage to the skin, depending on the fiber diameter and surface roughness varies, it is now recognized that the fiber diameter of more than 5μm, only with obvious irritation. Contact with glass fiber, rock wool workers, there are a few people with skin allergies, but so far not confirmed that these fibers themselves are allergens.

Glass fiber raw materials and their applications:
Glass fibers than organic fibers, temperature, non-combustible, corrosion-resistant, heat insulation, acoustic insulation, high tensile strength, good electrical insulation. But brittle, poor abrasion resistance.
Used in the manufacture of reinforced plastics or reinforced rubber, as a reinforcing material glass fiber has the following characteristics, these characteristics make the use of glass fiber is far more than other types of fibers to a wide range of development speed is also far ahead of the characteristics are listed below:
1, high tensile strength, elongation (3%).
2, high coefficient of elasticity, good rigidity.
3, elongation within the limits of elasticity and high tensile strength, so absorb impact energy.
4, inorganic fiber, non-combustible, good chemical resistance.
5, small water absorption.
6, scale stability, heat resistance are good.
