摘要:
The present invention relates to a method for making nitrosamine-free silicone articles by treating the mixture of vinyl containing organopolysiloxane and filler with hindered phenols, a nitrosamine-free composition and a nitrosamine-free article made therefrom. A preferred nitrosamine-free molded article is a baby bottle nipple.
摘要:
The present invention provides novel vinyl containing organopolysiloxane elastomers which possess excellent low compression set and heat aging characteristics and which can advantageously be formulated into liquid silicone elastomer moldable compositions.
