Why Choose Silicone for Your Manufacturing Solution?
Romar Engineering has long excelled in silicone manufacturing. Our world-class team of material engineers implicitly understand silicone properties – and that expertise is key to delivering our tailored and first-class silicone manufacturing solutions.
Silicone is a high performance material with a variety of potential uses, as Carlo Cartini, Romar’s Director of Technical Development, explains. “Silicone rubber is a fantastic material,” he says. “It’s incredibly resistant to UV light, oxygen, ozone and general wear and tear. It’s heat resistant up to 250 degrees Celsius. It feels soft and lovely against the skin. It has great biomedical properties. It’s very inert. It’s a wonderful material and it is fast becoming the material of choice for many, many applications.”
Diverse thermal and environmental properties
Silicone rubber is extremely resistant to high and low temperatures (-50°C to +250°C; specialty grades: -110°C to +300°C) with only slight changes in physical properties between -50°C and +180°C. It can be used indefinitely at 150°C with virtually no change in its physical properties.
Silicone rubbers are highly UV-resistant and able to withstand extreme wind, rain, salt and abrasion, providing higher durability than organic rubbers in external and some industrial environments. Silicone rubber has a water-repellent surface, and it exhibits good chemical resistance and flame retardancy. When silicone rubbers do burn, they do not produce noxious gas.
Silicone’s long-term tensile strength and weatherability lead to its usage as adhesives, lubricants and sealants in highly regulated industries such as aerospace, mining and transport, in electronic devices and computer technology, and in power distribution. Silicone rubbers can be modified to exhibit radiation resistance with the addition of phenyl groups to the polymer molecules, and thus are usable as a material for cables in nuclear power plants.
With the ability to bond diverse materials, including concrete, glass, granite, steel and plastics, and absorb stress and movement from wind or earthquakes, silicone products are also found in construction applications.
Excellent biomedical properties
Silicone rubber has high purity levels, compared with other polymers. It exhibits a number of other properties that make it suitable for applications that need to meet strict safety and certification requirements within the biomedical and food industries.
Silicone is inert, odourless and tasteless. It is resistant to bacteria, does not react with other materials and does not irritate the body. When used externally, internally or intravenously, silicone materials do not generate unwelcome by-products or trigger allergic reactions.
At Romar, we manufacture silicone products and medical grade silicone that meet stringent quality standards. Typical applications include tubing for drug delivery systems or heart pacemakers. Given its exceptional cushioning and ability to most closely approximate the consistency of skin, silicone is frequently found in prosthetics.
Flexibility for optimum processing
A key benefit of silicone manufacturing is its flexibility and suitability for most industrial and commercial manufacturing applications. It is easy to formulate and we can modify it to suit specific applications and standards requirements across sectors.
Silicone is naturally translucent but can be manufactured in a range of colours. We can create varying degrees of hardness or softness and modify coefficient of friction as needed. Silicone has exceptional insulation properties, but we can alter it to exhibit semiconducting properties.
Silicone is readily cured and silicone molding is ideal for products as diverse as medical implants, automotive components and bakeware.
