Barrier parameter is usually hard to acquire at special temperatures. This article mainly tell us a concept of permeability parameters data fitting and relative theoretical principles. Continue reading
It introduces the main characteristics and reasons of Low Permeability Materials by analyzing the objective factors of test methods, instruments, and test temperatures. Continue reading
When temperature become higher, the movement of gas molecule will be acuter, diffusion coefficient will be higher. Permeability coefficient has a direct ratio with film transmission rate . Continue reading
When temperature rises, the diffusion rate of permeance molecule in the polymer is accelerated; the energy of gas molecule is increased, so the permeability of the materials will be increased. Continue reading
Labthink has got an excellent testing results in a data comparison test presided by German Mecadi Lab and acquire a high praise. Continue reading
