One of the most unique protective lining systems in the market today is PYROFLEX® acid-resistant membrane system. This system is a flexible, uniformly thick sheet membrane used as an impervious barrier between acid-resistant brick and corrosion-prone steel, alloy or concrete shell. This non-porous, non-aging thermoplastic:
PYROFLEX® 500 acid-resistant membrane system is a fiber-reinforced composite applied in sheet form by fusing directly to a properly cleaned and primed surface without the use of an adhesive. It is an extremely dense material that absorbs less than 0.1% of boiling water. Because of its thermal stability, it has an outstanding performance record in masonry-lined towers.
PYROFLEX® DUPLY lining consists of PYROFLEX membrane with an overlay providing additional protection.
Additionally, we offer other lining materials to meet customer specifications, like:

Knight Material Technologies (KMT) is the world’s leading provider of hydrometallurgical brick linings, mortars and acid-resistance membranes. KMT’s proven solutions protect autoclave steel shells providing thermal, mechanical and chemical protection in elevated temperature and pressure environments.
Materials with good chemical resistance include polymers like polyethylene, polypropylene, and polyvinyl chloride (PVC), as well as high-performance plastics like PTFE and PVDF. Additionally, certain metals and alloys, such as titanium and Hastelloy offer excellent chemical resistance in various corrosive environments. The choice of material depends on the specific chemicals and concentrations involved in the application.
