Founded in 2014, Zhejiang Orcas refractories Co.,Ltd locate in Deqing county, Zhejiang province. The factory commits to the development of new energy-saving refractory industry. Our main products cover kinds of ceramic fiber, glass fiber and other refractories, such as ceramic fiber bulk, blanket, paper, board, textile, module, shaped pieces and glass fiber blanket, textile, and carbon fiber blanket, aerogel blanket.
Product Description
Fire resistant insulation at lowes ceramic fiber module is folded and compressed by ceramic fiber needled blanket, which is a kind of most commonly used adiabatic moudle in low temperature furnace. Simple and easy installation accelerates the construction speed of furnace lining. It has excellent chemical stability, resisting attack by most corrosive agents, expect hydrofluoric acid, phosphoric acid and concentrated alkaline.
