Its temperature resilience, as well as its non-stick and inert properties, means silicone rubber has wide ranging applications in the food and beverage production industries.

Silicone Engineering’s clients are drawn from all over the world and have previously included Heinz, Kraft Foods and Cadbury’s.

With its hygienic, durable and flexible properties as well as being temperature resilient and and non-stick, silicone rubber has a variety of applications which can be applied in the following sectors;

  • Food Processing
  • Dairy
  • Vending Tubing
  • Breweries
  • Antimicrobial Belting

Food Processing

The food processing industry calls for tighter regulations and specifications in order to maintain a high level of health and safety. Silicone rubber is widely used throughout the industry due to its high temperature rating and great sealing properties making it ideal for cooking and mixing processes. Silicone seals and gaskets can be used on food processing machinery such as dough and cake mixers in bakeries. As all of our silicone is FDA approved, food manufacturers can be confident that the silicone rubber used is completely safe when in contact with food.

Dairy Industry

Demands for higher quality standards and improved yields have seen silicone rubber replace organic rubbers across a wide range of applications. Durability and hygiene are the most common factors influencing the transition over to silicone. With Silicone Engineering’s suraSil™DS range of dairy tubing, durability, flexibility and hygiene performance are what sets us apart from the competition.

Durability
suraSil™DS dairy tubing has been specially formulated to provide strong wall structure and is tested to withstand the daily wear and tear of dairy parlours.

Flexibility
suraSil™DS dairy tubing stays flexible up to -60°C ensuring no cracking or splitting occurs during cold winter temperatures.

Hygiene
suraSil™DS dairy tubing has been specially designed with an ultra-smooth inner surface to reduce the risk of particle build up from the milk. The smooth inner surface of the tube increases the efficiency of daily hygiene cleaning, reducing the risk of harmful bacteria building up.

Vending Tubing

Vending machines serving hot drinks such as tea and coffee require not only the health and safety benefits of silicone but also its physical properties to withstand high temperatures and high levels of usage. Silicone Engineering’s suraSil™ tubing is commonly used as delivery tubes to transport the hot beverage from the machine to the cup. The smooth inner surface of the tubing helps reduce the buildup of residue left by the beverage, and also makes cleaning much more efficient.

As Silicone Engineering’s vending tubing is compliant with FDA, BfR and WRAS approvals, suraSil™ is ideal to be used in vending machine applications. Our silicone ensures no taste contamination and offers the durability to withstand constant use. The suraSil™ range is available in A-scale shore hardness of 30 to 80 for extrusions.

Breweries

With over 25 years’ experience, Silicone Engineering is now able to provide brewery manufacturers a product that is durable, translucent and affordable. Our range of silicone tubing has a low bursting pressure, which means that it can be used for brewery hoses / gaskets / process valves. Whilst many brewery manufacturers may still prefer to use copper pipes when brewing their beer, other mainstream manufacturers have identified silicone tubing as easy to install, maintain and replace. The tubing is translucent, making the flow of liquid and air bubbles visible. If you’re looking for the best grade tubing to use for brewing, use silicone.

Accreditations

Silicone Engineering solid GP products are fully compliant with the requirements of the U.S Food and Drug Administration (FDA) and the German BfR.

Products have also been tested and approved by the Water Regulations Advisory Scheme (WRAS). This means that all our general purpose (GP) products can be used with drinking water up to 85°C.

We provide a range of products that are widely used in the food and beverage industry, these include;

Discover the benefits of FDA Silicone Sponge Sheeting

Silicone Engineering’s fully FDA approved silicone sponge sheeting is the ideal material for the food, beverage and pharmaceutical industry.

Tested and fully approved by the Food and Drug Administration for the full list of ingredients within the sponge formula, the silicone sponge can be used with complete safety in food applications, whether the food be dry, aqueous or fatty.

FDA silicone sponge rubber has a variety of applications which can be applied in the following sectors;

  • Food and Beverage Manufacturing
  • Bakeries
  • Medical
  • Pharmaceutical

The new material has been independently tested by Toxikon to analyse the total extractable substances, and proven to meet all criteria for extractables required by FDA 21 CFR 177.2600.

The composition of this product has also been positively assessed according to German BfR recommendation XV on silicone for food contact (BfR Empfehlungen XV zu Silicone).

We also manufacture other grades of silicone sponge sheets

Food Safe

Our food grade silicone sponge can be applied in a number of forms, most commonly as gaskets and seals to provide excellent sealing properties in machinery or units due to its exceptional compression set (5%) and high elongation 500% to 600%. With its extremely low water absorption properties, water, dust and dirt ingress is prevented from entering the machinery and more importantly the product.

All known FDA sponge products currently on the market, only state ‘compliance to’ FDA standards such as the extraction requirement. This does not mean the product is fully FDA compliant. Silicone Engineering has developed a silicone sponge that can be officially called FDA approved. The sponge rubber is prepared using only ingredients that are permitted for use by FDA 21 CFR 177.2600.

Along with full FDA approval, silicone’s high temperature resistance makes it a material of choice when high heat is being applied to food and beverage processes. With a standard temperature range from 230°C to -60°C, silicone can be applied in extreme environments whilst maintaining its high performance sealing properties.

In addition to our FDA silicone sponge, our solid silicone is fully compliant with FDA regulation 21CFR177.2600, EC1935/2004 as well as being WRAS approved (Water Regulations Advisory Scheme) for contact with drinking water.
