Introduction to Alkylated Naphthalene
Alkylated Naphthalenes (AN) are a reaction of olefins with a naphthalene nucleus resulting in a base oil with excellent thermal and oxidative stability. In addition AN has first-rate hydrolytic stability and is miscible with other synthetic hydrocarbons, most notably Polyalphaolefins (PAO). Alkylated Naphthalenes summary:
- Temperature range of -30 to 180°C
- Excellent thermal and oxidative stability
- Good plastic/elastomer compatibility, can have issues at higher temperatures
- AN blended with PAO shows a synergistic effect
Keep in mind that if a Alkylated Naphthalene is used as the base oil for a grease, the thickener and additives also used in the formula will have an influence on the final characteristics and performance of the finished grease/lubricant.
Take a look at our typical thickener systems characteristics used to make a base oil into a grease.
