• Description:
  A study was conducted on the temperature dependence of the permeability of rubber gloves used by microelectronic workers to N- methylpyrrolidone (872504) (NMP). Gloves composed of butyl-rubber, natural rubber, or a combination of natural rubber with a trace of nitrile and neoprene rubbers were tested for permeation of NMP at temperatures ranging from 25 to 50 degrees-C. Condensation droplets were observed on the inner side of one of the natural rubber gloves and a large increase in the steady state permeation rate of this sample was seen when the flow rate was increased. The natural rubber and combination gloves demonstrated decreases in permeation resistance with increases in temperature and the breakthrough times and steady state permeation rates of these gloves were described well by Arrhenius relationships. No permeation through the butyl- rubber glove was seen at any temperatures. The steady state diffusion coefficients and activation energies were calculated and the experimental results were compared to those obtained using several permeation models.
