PURPOSE:To obtain a fluoro lubricant which can be used suitably for machinery having a rotary or sliding mechanism and consisting of thermoplastic housings or parts, by using a fluoropolyether. CONSTITUTION:A lubricant which is used for machinery made of thermoplastic and comprises a fluoropolyether or a mixture thereof. Examples of the fluoropolyether include those of formula I (wherein p, q, and r are each 0 or a positive integer; 2<=p+q+r<=200), those of formula II (wherein n is a real number; 2<=n<=60), and those of formula III (wherein the ratio of n to m is approximately 40:1; the molecular weight is about 400-7,000). Examples of the thermoplastics include modified PPO, ABS, AS, and HIPS. |
