Silicone Rubber
Silicone elastomer contact material
Silicone rubber is the elastomer family behind molded silicone brush heads and blades, valued for elastic recovery, weathering and a wide temperature range. Standard and fluorosilicone grades resist different fluids, so the grade is matched to what the tool meets.
What is silicone rubber?
A cured silicone elastomer, about 20–80 Shore A, density 1.1–1.3 g/cm³, water absorption below 1% and a compression set of about 5–30% depending on grade. Fluorosilicone grades add resistance to fuels and oils that standard silicone lacks.
Where is it used?
In our range, in the molded silicone food cleaning brush for conveyors, trays, tanks and removable food processing parts. More broadly it is used for heat-tolerant soft contact, bottle cleaning and squeegee functions in kitchen, laboratory and wet-process tools.
How hot can it run?
Data quote about -50 to 200°C for silicone rubber, far wider than most elastomers. The rest of the tool must take the same range.
Where does it fall short?
It is not for aggressive scraping, rust removal or metal deburring, and standard silicone swells in some oils and fuels; fluorosilicone is the choice there.
What should you tell us?
The job, the fluids and cleaners, the temperature, the hardness, and any food-contact standard. The page on silicone covers molded bristle heads in more detail.
Questions buyers ask about Silicone Rubber
Is silicone rubber the same as silicone?
In brushes, yes in practice: silicone heads and blades are made of cured silicone rubber. The grade decides hardness and fluid resistance.
Does silicone rubber resist oil?
Standard silicone swells in some oils and fuels. Fluorosilicone grades are used where oil or fuel contact is expected.
What temperature can silicone rubber take?
About -50 to 200°C, much wider than most rubbers.

Share what the brush works on, the temperature and chemicals it meets, the form you need — strip, disc, roller or hand brush — the quantity and a drawing or photo.
We reply to every request within 24 hours, with a quotation or with the questions we need answered first. If the brush can be made on our existing tooling, we make the sample directly. If it needs new tooling, we quote a sample fee and a tooling fee, and the sample fee is credited against the bulk order. Need an NDA first? We sign yours before you send drawings, and the files you send are never shown to other customers.
