Material Notes:
UL, Inc. has granted HST-II the highest thermal recognition ever achieved by any glass polyester laminate (U.L. File No. E81893). HST-II has a 220º C/210º C rating for 1/8" thick and heavier, and a 210º C/210º C rating for 1/32" thick up to 1/8" thick. HST-II is a high temperature polyester laminate that exhibits excellent retention of electrical and mechanical properties at elevated temperatures. Applications for HST-II can be found in high voltage transformers, D.C. motors and elsewhere when materials with high thermal indices are required. Available thicknesses - .031" - 2.00". Standard color - Brown.
