Close cooperation between SEFPRO and Glassmakers all over the world has greatly contributed to progress in the glass industy.
In Container Glass, the furnace accounts for no more than 20% of the total investment for a complete plant. However, the entire facility’s success depends on optimum furnace operation. SEFPRO provides container glassmakers with materials and solutions designed to ensure this success, taking into account the specific constraints of this market.
Flat Panel Displays, mostly LCD, have taken over the TV and PC monitor markets away from the bulky CRT screens. For glassmakers, this has created major challenges entailing development of new glass compositions, new processes and entirely new equipment. Benefiting from its unique R&D resources, SEFPRO is at the leading edge of refractory solutions, working hand in hand with the glassmakers in absolute confidentiality.
These glasses, with up to 12% Boron Oxide, are particularly demanding in terms of refractory corrosion. With its full range of fused-cast High Zirconia, and unique qualities of Isopressed Zircon Silicate materials, SEFPRO has the right answer to all furnace designs.
Crystal symbolizes the beauty and purity of glass. Totally defect-free transparency is an absolute necessity. SEFPRO materials, associated to its unrivalled experience in glass defects expertise, are a major asset for the glassmakers in this field.
Neutral Glasses are used for pharmaceutical applications. Although less corrosive than their Hard Borosilicates “cousins”, the high level of purity required by their application makes SEFPRO materials a major feature for these furnaces.
These glasses require by nature the very best level of quality. SEFPRO’s experience in the choice of refractories for each furnace area, and innovative solutions like ER 2001 SLX very low exudation AZS material, are at the glassmakers disposal to reach this target.
This Glass forming process is going through an exciting development thanks to the growth of Photovoltaic Cells, requiring extra-white, highly oxidized glasses. From furnace materials, down to the widest choice of solutions for the lip stones, SEFPRO is working side by side with the Glassmakers to face these new challenges.
The exhaustive range of SEFPRO materials allows to find solutions to all cases covering the extremely wide range of Enamel compositions.
Float Glass furnaces are long-term, heavy investments with lifetimes approaching now 20 years for the best ones. Glass quality, energy efficiency and safety are therefore the major axis for SEFPRO’s solutions and developments.
In the frame of rising environmental concerns, Insulation Fiberglass is facing a double challenge of fast growing market opportunities and increasing demands for limiting the process environmental impact. SEFPRO with its production capacities, combination of Chromic Oxide sintered and AZS fused-cast materials ranges, and R&D power, works with Glassmakers to build increasingly efficient furnaces while protecting our environment.
Lighting Glass covers a wide variety of families of glasses : Sodalime, borosilicates, alumino-silicates, etc…SEFPRO proposes solutions for all the needs, including the high quality expandables such as mandrels for the Danner process.
Given the very aggressive nature of Opal Glasses, furnace lifetime is a constant concern. SEFPRO’s wide range of High Zirconia Fused-Cast materials is a significant advantage when selecting the best adapted refractories.
Combining the isopressed Chrome and Zircon materials from Corhart (USA) and SG Linyi (China) with the complete range of vibrocast and pressed materials from Savoie Refractaires (France), SEFPRO is the world leader in offering complete, state of the art refractory sets for the Reinforcement Fiber industry.
