摘要： A fluororubber composition comprising 1 to 100 parts by weight of a needle-like filler or fibrous filler having an average particle diameter of 5 µm or less, an average particle length of 40 to 60 µm, and an aspect ratio of 10 to 12, based on 100 parts by weight of fluororubber. A fluororubber vulcanization-molded product obtained from the fluororubber composition has resistance against deformation due to the shape effect of the filler, and thereby can suppress the deformation of the oil seal sliding surface towards the sliding direction. More specifically, the fluororubber vulcanization-molded product can achieve less friction, while maintaining sealing properties by increasing the amount of oil pumping, from the initial use of an oil seal to after the abrasion of the oil seal.
摘要翻译：一种氟橡胶组合物，其包含1至100重量份的平均粒径为5μm或更小，平均粒子长度为40至60μm，纵横比为10至12的针状填料或纤维填料，基于在100重量份的氟橡胶上。由氟橡胶组合物获得的氟橡胶硫化成型体由于填料的形状效果而具有抗变形性，能够抑制油封滑动面向滑动方向的变形。更具体地说，氟橡胶硫化成型产品可以实现更少的摩擦，同时通过增加从油封的初始使用到油封的磨损之后的抽油量来保持密封性能。

摘要： There is provided a sealing apparatus capable of suppressing wear of a seal lip portion in a low temperature environment. A sealing apparatus (1) includes an elastic body portion (2) made of an annular elastic body and a reinforcing ring (3) made of an annular metal. The elastic body portion (2) includes an attaching portion (4) fitted in a portion to be attached and a seal portion (5) in close contact with a shaft in a manner the shaft is slidable. Grease is applied to a seal lip portion (51) of the seal portion (5). The grease contains at least one of a synthetic hydrocarbon oil and a mineral oil as a base oil and has a low temperature starting torque of 25 N·cm or less at -30°C.
