What is the molecular weight of ETFE and PTFE?

Question

i know that molecular weight effects the tensile strength and i know that ETFE has a higher tensile strength than PTFE so i assume that the molecular weight of ETFE is more than PTFE but i need to prove this

Answer 1

PTFE:

Molecular formula CnF2n

Density 2200 kg / m^−3

Melting point 327 °C

ETFE:

It is a copolymer comprising of tetrafluoroethylene (C2F4) and ethylene (C2H4).

ETFE has strong molecular structure and so the tensile strength.
