Abstract

To reduce the weight of the engineering plastic Nylon 6 resin, two high-temperature foaming agents, p-toluenesulfonyl semicarbazide (PTSS) and 5-phenyltetrazole (5-PT) (0-10 phr), were added and foamed without other additives. We investigated the effects of the foaming agent type and content on the foam density (g/cm3) and percent weight reduction rate of the Nylon 6 foam, and 5-PT exhibited better foaming performance than PTSS. In the case of 5-PT, the weight reduction rate was above 36% when the blowing agent content was 1.5 phr or higher, indicating that 5-PT is an effective blowing agent for reducing the Nylon 6 foam weight. Additionally, we studied the effect of the nucleating agent Talc content (0-0.4 phr) on Nylon 6 foaming, and the nucleating agent Talc considerably reduced foaming.
