Glass packing HT type ESS-HT
Glass yarn of type HT applied in this packing is characterized by excellent thermal and mechanical resistance. Thanks to the applied strand, these particular characteristics are enriched with high elasticity of created packing. At exposition to high temperature, the packing loses its green colour, which does not affect utility parameters of the product. On a special order, the packing can be made with an elastomer core (type ESS-HT+R), which substantially increases the elasticity of sealing. The section and the material of the core is selected individually, depending on specific operating requirements.
Application
ESS-HT packing is a resting sealing, ideal to be used in furnaces, flaps, hatches, holes cleanout openings and expansion gaps. Applied e.g. in power plants (coal mills), in metallurgy (coke batteries), founding (forms sealing), ceramic industry (ceramic carts and furnaces), municipal economy (coal furnaces).
