Plastics are desirable as substrates for gas microstrip detectors (GMDs) because of their flexibility, low density and long radiation length. GMDs have been fabricated on white Tedlar which has bulk electrical conductivity and on ion-implanted Upilex which has a thin electrically conductive layer on the surface of an insulator. The shielding effect of the thin conductive surface layer on the GMD gains has been investigated. High X-ray rate measurements show no charging or loss of gain for ion-implanted Upilex GMDs. Three such GMDs were recently tested in a high intensity beam at CERN. The anode signals were read out using fast, low noise, high gain amplifiers. Preliminary results of the test are presented.
