Polyether block amide Pebax® MH 1657 resin is a thermoplastic elastomer made of flexible polyether and rigid polyamide.
Pebax® MH 1657 resin is an inherently dissipative polymer and can be dry blended or compounded with an isolative polymer to lower the surface resistivity of the final part.
This hydrophilic grade when extruded into either a thin film or laminated on to a substrate also offers excellent permeability to moisture vapor while remaining waterproof.
Main applications:
Breathable membranes.
Permanent antistatic additive.
Packaging:
This grade is delivered dried in sealed packaging (25 kg bags and 550 kg rigid containers) ready to be processed.
Shelf Life:
Two years from the delivery. For any use above this limit, please refer to our technical services.
