NP513B

It is a pre-preg composed of a high temperature, electrical grade epoxy resin (T_g= 170°C), combined with a woven glass substrate. This grade of pre-preg is not flame retardant. With a non-brominated resin system, the product offers high mechanical strength at temperatures up to 170°C. Properly cured, it will retain 50% of its room temperature flexural strength at elevated temperatures (150°C, after conditioning at 150°C for one hour), E-1/150, T-150. NP513B is softer than NP511B making it easier to form until its final cure. This electro-mechanical grade is suitable for power generator slot insulation.
