Product description
Dureflex® PT1700S is a specially formulated aromatic polyether based film.
Applications
Dureflex® PT1700S is for applications requiring high moisture vapor transmission. Dureflex® PT1700S maintains mechanical properties essentially equivalent to a conventional polyether TPU, yet this material allows water vapor to pass through it at a rate of 3 to 5 times greater. This material is intended for thin gauge film. Dureflex® PT1700S is supplied on a polyethylene carrier. As with any product, use of Dureflex® PT1700S in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
