Vehicle valve stem seal |
abstract |
The present invention provides a vehicle valve stem seal having both durability and sliding properties at an extremely high level in addition to usual sealing performance. The present invention is a vehicle valve stem seal comprising an elastic member with a seal lip portion on an end of a valve stem guide, the seal lip portion slidably closely contacting with a valve stem of an engine, wherein the elastic member is formed of a composition containing a fluororubber and a fluororesin and has projecting portions at least on a surface of the seal lip portion, the projecting portions being substantially formed of the fluororesin contained in the composition, the fluororesin is a copolymer including a polymerization unit derived from ethylene and a polymerization unit derived from tetrafluoroethylene, and the fluororubber is a polymer including a polymerization unit derived from vinylidene fluoride. |
