Schluter-DITRA-XL is manufactured using high-density polyethylene (HDPE), which does not rot and is highly resistant to solutions containing salts, acids, and alkalis, as well as many organic solvents, alcohols, and oils. Its resistance to specific stresses can be provided if concentration, temperature, and exposure time are known. Schluter-DITRA-XL is waterproof and resists the transmission of vapor. The material is inert, non-toxic, and physiologically safe.
