（全）氟弹性体组合物
摘要：
可通过过氧化物方式固化的(全)氟弹性体组合物，相对于100phr(全)氟弹性体，所述组合物包含：0.5－50phr作为填料的硅石，其具有根据DIN ISO 787－9标准测定的大于7，优选大于8的pH值；0.5－10phr作为交联剂的具有通式(I)的二烯，其中：R1、R2、R3、R4、R5、R6彼此相同或不同地为H或C1－C5烷基；Z选自C1－C18线性或支化亚烷基或亚环烷基，任选含有氧原子，优选至少部分氟化的或(全)氟聚氧亚烷基。
摘要（英）：

A (per)fluoroelastomeric composition curable by peroxidic way comprises: 100 phr as (per)fluoroelastomer; as filler, 0.5-50 phr of silica having a pH value, determined according to the DIN ISO 787-9 standard, higher than 7, preferably higher than 8; as crosslinking agent, from 0.5 to 10 phr of a bis-olefin having general formula (I) wherein: R1, R2, R3, R4, R5, R6, equal to or different from each other, are H or C1-C5 alkyls; Z is selected between a C1-C18 linear or branched alkylene or cycloalkylene radical, optionally containing oxygen atoms, preferably at least partially fluorinated, or a (per)fluoropolyoxyalkylene radical.
