Problems solved by technology
[0009] However, the disadvantage of OBSH is that the amount of gas released during foaming is relatively small and the decomposition temperature is low. Therefore, under the general processing conditions of vinyl chloride resin, compared with ADCA foaming agent, it lacks foaming characteristics such as foaming ratio, foaming rate, etc. Foam cell stability, etc.
