Greater cure time (crosslinking) and greater elastomer content increases the shrinkability as well as flame retardancy of the blends. Additive flame retardants hamper the heat shrinkability of the blend to some extent depending on various factors. The depression of shrinkability due to interference of flame retarding agent is less for cured sample and elastomer‐rich blend compared to uncured and plastic‐rich blend, respectively. At high temperature the shrinkability is higher, but the sacrifice of shrinkability in the presence of flame retardants increases with increase in temperature, for a particular blend. The highest flame retardancy is obtained in presence of Sb 2 O 3 /Chlorohor and TPP/Zn metaborate.
