153553Temperature Resistance

DSP has excellent ability to withstand temperature cycling without loss of its properties. Hence, its applications include providing a more stable microstructure. This suggests that specialized curing regimes will be necessary for optimum performance. However, 200 to 250° C is the upper limit for this system. As a solution to overcome this limit, polymer impregnation with a high-temperature polymer (Novolac epoxy resin) has been used. It is verified by experiment that vacuum impregnation can significantly improve flexural strength.
