If you’re planning to use plastic hinges, you’ll need to choose the right lubricant. Hinges consist of two leafs that, when interlocked, form a central knuckle. The knuckle is the pivot point, allowing one leaf to swing away from the other leaf. Regular lubrication ensures that the hinge’s leafs can move smoothly while also minimizing the risk of squeaking and corrosion.<\/p>\n\n\n\n

Beware: The Wrong Lubricant Can Damage Plastic Hinges<\/h2>\n\n\n\n

You can’t use just any lubricant on plastic hinges. While there are many general-purpose lubricants, some of them can damage objects made of plastic, including hinges.<\/p>\n\n\n\n

Lubricants contain chemicals, such as petroleum distillates. Plastic reacts differently to these chemicals than metal. When exposed to petroleum-based chemicals, plastic can swell, crack or become brittle — and it doesn’t take long for damage such as this to occur. Research shows that petroleum-based chemicals can damage plastic in as little as 48 to 72 hours.<\/p>\n\n\n\n
