Description

They are block copolymers made up of rigid polyamide blocks and soft polyether blocks. Manipulating these blocks and their relative ratio allows for the creation of a large range that spans the flexibility spectrum from very hard and rigid to very soft and flexible, without the need for plasticizers. These unique polymers maintain the highly desirable combination of the toughness traditionally associated with polyamides and the flexibility/elasticity more often seen with polyethers/polyesters.

This material data has been provided by M-Base.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
