HEPHA’s main business is the design and manufacture of ready-to-use refractory castables packaged in bags or Big Bags.
Our product range includes
Dense castable refractory concretes with medium, low and ultra-low cement content
Dense gunning refractory concretes (standard gunning and low-cement-content gunning)
Our dense refractory concretes are based on raw materials such as silica-alumina, bauxite, chamotte, andalusite, mullite, silicon carbide, zircon and other special materials
Insulating castable or gunning refractory concrete
Our insulating refractory concretes are based on raw materials such as vermiculite, light chamotte, perlite and expanded clay
Throughout the manufacturing process, from monitoring the raw materials through to storage, our castables are inspected and tested according to the applicable standards.
Samples are taken at each stage and laboratory tests are carried out (mechanical tests, particle size, proportioning, etc.). That is how we guarantee that we deliver materials which fully comply with the technical specifications.

HEPHA’s LIGHT RANGE comes in castable and gunnable versions (LIGHTCAST and LIGHTGUN). From a density of 0.5 with very low thermal conductivity to a level of 1.7 for products that combine mechanical resistance with insulation, the range covers numerous applications. Our silica-alumina are recognized in the glass, incineration and cement industries, as well as many other fields, and are present in a wide variety of compositions, specific to each industry.
HEPHA’s STANDARD RANGE comes in castable and gunnable versions. These products are particularly recommended for zones operating at low temperature (< 1000°C) with little or no ceramization. Also suitable for temperatures of up to 1800°C, the standard range is recognized for its robustness and easy implementation.
