Physical and mechanical behaviour of polysiloxane filled silica sheet

Polysiloxane (POS) is a unique polymer and contains silicone and oxygen in polymer chains. Degradation is a common problem of polymer material which leads to material properties decreased. Heat, light and chemicals are the main cause of polymer degradation (Moeller, 2008). In order to reduce the ten...
