A high-temperature, abrasion-resistant bearing polymer has been developed by Vesconite Bearings from all food-grade ingredients.
The polymer is known as Hitemp 150 FG (food grade), and its name signifies that it can be used in applications that run at temperatures up to 150ºC and in which food contact is incidental or likely.
The previous version of Hitemp 150 did not explicitly use food grade ingredients, but, as a result from calls from the food industry to produce a similar hard-wearing product for use in food applications, alternative ingredients were sought for food safety.
“We have produced a product in which a food-approved ingredients have been used,” comments technical sales representative Eddie Swanepoel.
“It is cream with a streaky marble look as opposed to the previous rust-coloured Hitemp 150 polymer,” he notes.
The next step is to have the polymer approved as compliant with Standard 51 of the US’s National Sanitation Foundation (NSF), the standard that deals with polymer materials and components used in food equipment, including products that come into contact with food and beverages.
Vesconite Bearings is confident that the newest version of the polymer will be judged to be food grade since all the raw materials ingredients are certified as food grade.
