Permeability of elastomers
WebTwo mixed-matrix membranes (MMM) for gas permeability test were prepared by introducing inorganic fillers (silica (SiO2) and magnesium oxide (MgO)) in the composite blend of epoxidized natural rubber (ENR) and polyvinyl chloride (PVC). Inclusion of SiO2 and MgO particles in the membranes resulted in pores formation as observed through … WebThe properties of thermoplastic polyamide elastomers depend strongly on the type of polyamide block, the type of polyether block and the length and number of blocks. The key properties of TPE-A include: Good processability. High temperature resistance (up to 170°c) Good solvent resistance.
