A throw: Degradation of the anti adhesive revettement

After a few uses (3 since purchase) the non-stick coating of the plate began to detach from the plate and to stick on the pastry that was placed there! Is it a carcinogen as is the cooking stoves Teflon ??? It also seems that I have exceeded the return period of a day and it remains for me to throw this material in the TEFAL brand! But is it the hardware of this trademark. Eventually I doubt having also another plate of this type for years with no evidence of deterioration has appeared there ...
