从下面的描述里能否判断此grease 是否能用在尼龙齿轮上？ 多谢
The Xtreme Performance Grease with PTFE (L80) to use where others fail. L80 is a blend of Polytetrafluoroethylene (PTFE) fluorocarbon particles in a specially prepared lithium-based, water-repellent grease. L80 can be used in almost any greasing application to improve lubrication and reduce temperature and wear.
Benefits
L80 keeps water and dust out while a plating of PTFE is applied to the mating surfaces under working conditions. Seal performance is improved and operating temperature reduced, resulting in less grease "throw". L80 is applicable to the majority of situations specifying grease lubrication, especially in high pressure, water and salt-water conditions including wire ropes.
L80 has a continuous temperature operating range of -9°C to 150°C.
L80 provides a residual lubrication, which is added insurance, combined with savings through less wear and downtime, making it an economical benefit. Smoother running, increased efficiency and prolonged machinery life, less labour and less volume of lubricant, all indicate higher profits. Where L80 has been used on a continuous basis, seizing and pitting will not occur on the friction surfaces.

我搜到mobil 28 可以用在尼龙上，但是澳洲卖的太贵了。

好像不可以，因为是Petroleum-based，也是原油里提炼的基础油。一般来说multi purpose grease都是petroleum-based，主要用于金属和金属间，塑料和橡胶不适用。

Mobilgrease 28好像跟这个L80差不多，看官网说主要用于轴承齿轮什么的，可能也不适合塑料和橡胶。但尼龙……不太了解，如果是重要零部件，感觉还是谨慎为上。不知道Penrite的rubber grease能不能胜任。

可以试试Inox MX-8。Marine Grease.BCF就有卖。我是用在硬塑料的材质上。

食用机器上用的应该可以？像kitchenaid上有塑料的齿轮

哪里写Petroleum based？我找了半天没找着。

wd40很多都不行的。这东西不能用在bearing上。

记得在哪里看到过，褐色的multi purpose grease一般都是petroleum based。另外facebook上我问过valvoline关于它的MULTI LUBE LITH 2EP AND 3EP，回复说不可以用于塑料和橡胶，而它们的TDS文件里也没有明确说是petroleum based，只说lithium soap based.

还记得哪里看到说红色的rubber grease一般提炼自vegetable oil，对塑料和天然橡胶也是极友好的

不用费劲了，Molykote EM-30L Grease去查这个就行，专业用在塑料齿轮上的合成润滑脂
打印机里面的齿轮基本都是塑料的，都不给上这么好的
