To cater to anyone’s predilection or necessity, silicone rubber is offered in an array of colors from red to blue to black. There is even a translucent rubber sheet! Commercial manufacturers take advantage of the customizable capabilities of silicone rubber and produce colorful, eye-catching goods such as cell phone cases and baking utensils. Laboratory and food handling industries use white silicone rubber sheets to easily spot contaminants on the material’s surface. Whether it is purely aesthetic or strictly functional, the coloring of silicone is a handy feature of this elastomer.
Silicone – Premium Grade – Black – 60A
In its uncured state, silicone rubber is a highly-adhesive gel or liquid. In order to convert to a solid, it must be cured, vulcanized, or catalyzed. This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.
A common way of coloring silicone is to apply a pigment paste when the silicone sheet is on a roll mill. At this point of the manufacturing process, the rubber has not yet been cured. The paste can be blended into the material fairly easily by simply applying the paste with a paint scraper or similar instrument. When using pigment paste, virtually any color of silicone can be produced.
Silicone CG White – 50A
- White silicone sheet rubber features a smooth surface texture
- Has a good level of resistance against fungus
- Can be used outdoors thanks to durability against UV and ozone
- If you need a custom seal or gasket made out of this white silicone rubber, we encourage you to send in a drawing of the parts needed
Non-Marking, Professional Aesthetic: While other rubbers often come in a standard black, we offer a white colored alternative. White nitrile is meant to give an application a sleek, modern, and professional appearance while functioning the way a proper nitrile elastomer is supposed to. Even more importantly, a white elastomer is a non-marking material that will not leave any marks or stains on the objects it comes into contact with. The white colored nitrile is suitable for use in cosmetics, grocery stores, and medical applications where white is better suited for aesthetics than black.
Oil-Resistant Rubber: Nitrile, or Buna-N rubber as it was originally known, was developed to be an oil-resistant alternative to natural rubber back in the years after World War I. Nitrile material is still used today whenever good oil and grease resistance is needed. White nitrile can resist organic and synthetic oils. While other types of elastomers can degrade when exposed to oils and greases, nitrile rubber can keep its form and integrity, making sure that it does its part to keep your application functioning.
Silicone CG Gray – 50A
Normally, pigment pastes are used for commercial products and not industrial parts. There is no justifiable use for a pink gasket! Yet it’s common to see parts such as gaskets and seals made from colored material like red silicone sheets. This is because there are certain additives that inherently color the elastomer. For example, heat stabilizer additives are especially known to affect the shade of silicone, often resulting in a red, black or white silicone rubber sheet.
As previously mentioned, translucent rubber sheet is easily achieved since it is generally produced in this form naturally. No other rubbers can achieve the same translucency as silicone. This stands out as one of silicone’s defining characteristics. This ability is an invaluable feature for medical devices that require the properties of rubber with a degree of visibility through the material. This is just one of many functions of a colored silicone sheet!
Silicone CG Red/Orange – 70A
- Comes in a red/orange color
- Good resistance to materials like fungus
- Also available in lower durometer options
- Hard silicone rubber with a smooth surface texture
- Rolls of this sheet silicone are 25′ or 50′ depending on gauge
Hard Silicone Rubber: A rating of 70A indicates one of our most durable elastomers in stock. It is very important for to have a longer lasting wear part, even for the more commercial mid-grade types of applications. Solid silicone fights permanent physical indentation better than softer versions of this product. This hard silicone rubber’s durability can also be enhanced by the material’s thickness gauges, which come in options ranging from 1/16″ to 3/8″. Please keep in mind that this material is not recommended if you are looking for sheet rubber with good flexibility.
High Temperature Materials: Silicone is known to be one of the most heat resistant elastomers currently available. People regularly employ silicone for a wide range of heat related applications, such as laboratory and automotive activity. This sheet silicone rubber can withstand temperatures reaching up to 450 F. At the same time, these high temperature materials are also comfortable in cold settings, specifically to -103 F.
