Introduction
The thermal insulation lining is made of thousands of needles that continuously sew fine inorganic fibers up and down, and then comb them into felt. The main component is silicon dioxide, and there are small air cavities inside the fiber felt, so it has excellent thermal insulation and sound absorption properties, and can withstand long-term heat up to 550°C. It has good structural strength, does not contain adhesives, no carcinogens, high heat resistance, and corrosion resistance.
