Why Choose Silicone Rubber?

Silicone is a remarkable variety of rubber that offers some outstanding properties that can make it the clear choice among competing solutions. Firstly, silicone can handle very high temperatures in operation, up to 230°C (446°F). This allows it to maintain its properties at elevated temperatures that many other rubbers will not be able to handle! In addition, it has excellent resistance to UV and weathering, making it outstanding in outdoor applications. This includes heat, cold, freezing, direct sunlight, etc.

Silicone also has a low compression set – this means it can be compressed for a long period of time and will bounce back to close to its original profile when the weight has been removed. Think of this in a sealing application such as a door which is open and closed many times. The silicone will maintain the seal when compressed and will then return to its original form once the door is reopened. Also, the product is food safe and Redwood Plastics and Rubber can supply it in a new FDA blue variety.

There is a silicone rubber shortage currently in North America but not here! Redwood Plastics and Rubber carries significant levels of silicone stock in our central warehouse including FDA blue.

New FDA Food Safety Rules

The U.S. FDA is putting the finishing touches on some major rule changes and the rest of the world needs to take note (read more here). Why? Because these rules do not only affect domestic food but imports as well which must now be held to the same FDA standards. The emphasis of the new rules will be on prevention instead of reaction. Functionally, this means companies will be required to have a written, preventative food-safety plan that addresses food quality concerns. How do these rules relate to plastics? One word: contamination.

The threat of contamination is behind the development and recent proliferation of blue FDA approved plastics as well as X-ray and metal detectable acetals and UHMW-PE. These plastics could, and should, play a key role in preventative food safety moving forward. The plastics can be caught by detection machines if they ever break into the food and the blue plastic can be easily spotted by workers on the processing line. There is no excuse why these plastics cannot be implemented: they are FDA approved, have obvious advantages over traditional natural grades of plastic, and are available in several grades – even a FDA approved dryslide (extra low coefficient of friction) specialty grade! Like it or not, these new FDA rules are coming and formulating your preventative food safety plan should involve Redco foodsafe plastics.
