Lotryl® grades are used for making monolithic breathable membranes with the moisture vapor transmission rate (MVTR) suitable for housewrap, roofing underlayment membranes, medical gowns… High polarity and low crystallization rate induce very good bond between Lotryl® and substrate (woven or fabric fibers).

Recommended Lotryl® grades:

• Lotryl® 20MA08
• Lotryl® 28MA07
• Lotryl® 29MA03
• Lotryl® 40MA05T

-Lotryl® resins have moisture breathability according to their Methyl Acrylate content, especially the grades with more than 20% of Methyl Acrylate.

-These Lotryl® grades are widely used for Breathable Membranes due to their excellent processing properties particularly Lotryl® 20MA08 & Lotryl® 28MA07 these resin can be used pure. They can also be blended with breathable copolyamides and copolyesters to improve their processability and reach high MVTR.

-The Combination of Lotryl® 40MA05T & Lotryl 28MA07 could cover a broad range of permeability make this blend a suitable choice for every application in construction.
