Foam glass tube
Foam glass is a new type of inorganic material with uniform and independent closed (closed) air gap structure, which is made from ground glass powder as the main raw material by adding foaming agent, melting foaming and annealing cooling processing. Due to its moisture-proof, fireproof, and anti-corrosion properties, as well as the long-term performance of glass materials, this new material is highly favored by users in harsh environments such as insulation, deep cold, underground, outdoor, flammable, humid, and chemical erosion.
