The oak models the sponge heat preservation board tube main feature is the closed foaming structure, the thermal conductivity is small; Has the fine heat insulation effect, but energy conservation consumption; The closed type bubble structure and the compact epidermis cause the water vapor not permeable, and the water-absorptivity is low; The product rich flexibility, and divides into the oak to model the heat preservation board, the oak models the tubular holder work great convenience, the labor saving saves on materials; Outward appearance refined clean; Is suitable the temperature range broadly (- 40℃ to 105℃) the weathering resistance to be good, prolonged practical; The unique being flame-resistant formula, the naming material has the fine fire protection being flame-resistant effect.
