A versatile new NBR material

With its new prod­uct devel­op­ment P 300, seal man­u­fac­tur­er C. Otto Gehrck­ens now expands its range to include an NBR mate­r­i­al that pos­sess­es cru­cial approvals for use in the food and drink pro­duc­tion indus­try. P 300 is cer­ti­fied to FDA 21 CFR 177.2600 plus 3‑A San­i­tary Stan­dard, and also com­plies with the essen­tial EU Direc­tive (EC) 1935/2004. COG’s com­pound is also man­u­fac­tured with­out the use of ani­mal-derived ingre­di­ents, there­fore also meet­ing the ever-more com­mon require­ment that seals that come into con­tact with food­stuffs should be guar­an­teed ADI-free.

As an NBR mate­r­i­al, P 300 impress­es thanks to its good mechan­i­cal prop­er­ties, which in com­bi­na­tion with its high wear resis­tance and high lev­el of sta­bil­i­ty means it can be used in the widest pos­si­ble range of appli­ca­tions. This resilient prod­uct inno­va­tion there­fore comes into its own in sys­tem com­po­nents that are sub­ject to intense mate­r­i­al stress, and is also suit­able for dynam­ic appli­ca­tions. Fur­ther­more, P 300 also demon­strates excel­lent resis­tance to oils and fats, and is also resis­tant to dilut­ed acids and alka­lis. These prop­er­ties, along with its var­i­ous approvals, mean that this new NBR mate­r­i­al is of par­tic­u­lar inter­est to the food indus­try. It has numer­ous poten­tial uses in this sec­tor, such as for exam­ple in the milk and meat pro­cess­ing indus­tries, bev­er­age pro­duc­tion or ice cream production.
