Latest Silicone Engineering Case Studies

See below some examples of ways in which Silicone Engineering have helped industry leaders to optimise their production chain by providing silicone solutions to a range of industry applications.

Global Construction Company

Silicone Sealing for LED Lighting

Silicone Engineering worked closely with a large engineering company who specialise in tunnel construction.

They were experiencing the problem of fogging within the LED lighting units which light the tunnel and wanted Silicone Engineering to develop a silicone solution to combat this.

Our engineers came to the conclusion that the light quality had decreased due to fogging; a common problem which occurs when volatiles are released from a silicone at high temperatures if the silicone has not been cured properly in manufacture. As the LED lighting heated up, this was causing volatiles to be released and therefore fogging occurred within the unit. Fogging is a problem directly related to the cheaper forms of silicone available on the market.

Silicone Engineering worked with the company to select the correct silicone grade for the application, taking other factors into consideration as well.

Not only is fogging a common problem in LED lighting applications when cheap silicone is used, but water and dust ingress occurs too if the silicone is not closed cell. Our silicone sponge is closed cell with extremely low water absorption and also holds IP rating of IP65 and IP66 ensuring the lighting units are sealing to the highest standards.

Leading Restaurant Chain

Silicone Solutions for the Restaurant Sector

One of the UK’s leading restaurant and pub chains contacted Silicone Engineering in an effort to source a silicone replacement for cotton cloths used in their pubs and restaurant chains. The decision to replace the cotton cloths was really one of necessity due to new Food Quality Standards. The cotton cloths are now classed as “unhygienic” and some of the kitchen staff were getting burned due to the poor heat resistance they offer.

The cotton cloths were also causing a safety risk as they were often the source of fires when attempting to clean them. The fires were caused when the cloths were being dry cleaned as the cooking oils on the fabrics would catch light. Silicone was seen as an ideal replacement as not only is it an FDA (Food & Drug Association) approved material but it has excellent temperature resistance, ranging from -60°C to 230°C, and also can be wiped clean due to silicone’s non-stick properties.  

After an initial discussion over the telephone, a meeting was arranged to discuss the customer’s exact requirements in order to provide the best solution. The customer decided that rather than having simple cut silicone sheets, they would prefer a moulded sheet. This would enable them to achieve a pattern or dimpled finish to the new cloths and give the product a better surface for gripping the oven dishes and plates.

A sample order was then sent out to allow the customer to trial the sheets in the kitchens before being approved for bulk production.

The new silicone cloth replacements are now in service and are being rolled out to all their pub and restaurant chains in the UK.

Major Confectionary Manufacturer

A major confectionery manufacturer was experiencing problems with gaskets in the pipe work of their production-line. Seals were splitting in pipes that carried cocoa powder to specific food mixers; this was causing the cocoa powder to escape and resulted in significant production downtime for the manufacturer.

We arranged to visit the client and their chief engineer demonstrated to us the problem first-hand. While on site, we took samples and measurements of the problematic gaskets. We determined neutraSil™ to be the most suitable of our products to address the leaking seal issues faced by our client.

The client was particularly impressed that neutraSil™ would not only solve the problem but additionally, offer the benefits of anti-microbial defence. Prototypes of neutraSil™ gaskets were produced for approval and testing. After a four-week trial of the prototype gaskets, a follow up visit to assess performance was arranged. It was found that no leaks had occurred throughout the duration of the trial. In response to the positive results, the gasket was approved and orders were promptly placed by the client to replace all existing seals on the product lines with new neutraSil™ gaskets.

Solar Panel Laminating Company

Our client offer laminating solutions for the solar panel manufacturing industry. They have the newest multilevel laminator on the market. The issue our client was experiencing was the membranes were splitting, which in turn was causing a loss of vacuum during the lamination process. The cause of this problem was the way they were putting the screws through the sheet which was causing cracks in the material, therefore reducing the life span of the product. Our specialist team here at Silicone Engineering went to visit the client over in Italy to discuss and try to resolve the problem.

The purpose of the visit was to understand how the laminator machines work, to visualise were the silicone membranes fit onto the machine and to discuss the issues that they are experiencing with the silicone membranes that they are currently using. The key points that our client was looking for in the silicone membranes was to have an increased product life cycle by the way of improved elongation and tear strength. After samples of the clients current membrane material was tested in our laboratories, the product test data, compared with our kSil™VAC silicone, highlighted that our tear strength and elongation was far superior to the material that they were currently using. After a trial period of testing the material on their laminators, the client was happy with the results which led to a complete product solution to the clients processing problem.

T.W Holden & Son

Jim Holden, Dairy Farmer, Ribble Valley in Lancashire

"We were using conventional black rubber tubing in our milking prior to 2006.  The rubber tubing is soft state when fitting to the milking machine. However over a period of time with continuous use twice a day, (milking and hygiene cleaning) the rubber becomes hard and starts to corrode inside.  This creates the build up of milk in the little cracks and in turn, particles of rubber were entering into the milk supply.  This obviously can affect the quality of the milk and also increases the bacteria build up, something which is of great concern to me and the quality of my milk. On average we used to change the tubing approximately every six months.

We started to use the Silicone Diary tubing and found the quality of the tubing far superior to the rubber. When the hygiene clean is completed the silicone allows a thorough clean every time and does not leave any milk residue in the tube at all due to its extra smooth inner bore.  This has improved our milk bactoscan results (bacteria in the milk) considerably. 

Also due to the silicone retaining its properties, it does not crack therefore no particles are entering into the milk, increasing the quality of our milk supply. The tubing lasts at least four times longer than the black rubber tubing so in the long term helps to reduce the costs for milking production.  The diary tubing that we have trialled from Silicone Engineering has been of excellent quality, and the longevity is excellent."
