VITOFLEX
CM-L

One-sided self-adhesive, soft cellular rubber for protecting, damping, insulating and sealing

VITOFLEX CM-L is a one-sided self-adhesive, flexible cellular rubber with a closed-cell structure, based on EPDM (Ethylene Propylene Diene Rubber). VITOFLEX CM-L is resistant against many acids and alkalis at standard concentrations, water and steam up to 100°C, seawater, potassium and sodium compounds (for example saline solution), aqueous alum, detergents, photographic chemicals, cold ammonia, acetylene, alcohols, glycerine, glycol-based brake fluids and antifreeze, carbonic acid, ozone, silicone oil and grease, aqueous chlorinated lime; as well as wet and dry chlorine gas, hot ammonia and hydrochloric acid.
