I'd like to know CO2 permeability of pet and nylon

[ankur2061]

Gas permeability (CO2, oxygen) for polymers such as PET and Nylon determines the barrier properties for beverage storage in bottle-grade PET or Nylon. Are you doing some research on barrier properties? If such is the case than the permeability is a function of the composition of PET / Nylon or its blends with other co-polymers and will vary from producer to producer. Your best bet is to contact a PET and Nylon manufacturer to get these properties.

Some general information is available at the following links:

Hope this helps.
