Refractory blanket LYTX–212 / LYTX-312 / LYTX-512

Price: on request

 
Ceramic fiber blanket is a kind of new type refractory material that supplied to the customer. It is with white color and regular size and without any binder to set fire-resistant, heat preservation and thermal insulation in one. Luyang ceramic fiber blanket can keep its excellent tensile strength, toughness and fiber structure when it is used in the neutral and oxidizing atmosphere. Luyang ceramic fiber blanket are unaffected by oil stain and it thermal and physical properties are recovered after drying. All the blanket products are manufactured by spinning fibers and have excellent chemical stability same as its corresponding bulk fiber and higher strength in room temperature and after heating.
