Rubber
Elastomer contact material
Rubber is a family of elastomers, not one material. In brushes it is used for squeegees, wipers, paddles and soft-contact elements that push liquid or product rather than scrub. Which rubber, and how hard, decides whether it suits the chemicals and temperature, so the compound has to be named.

What is rubber in a brush?
Natural or synthetic elastomers, such as natural rubber, EPDM, nitrile, neoprene or silicone, that recover after being bent or squeezed. Hardness runs from about 30 to 90 Shore A, density from about 0.9 to 1.4 g/cm³, and water absorption is very low.
Where is rubber used?
In our range, in nearly thirty brushes: tire mold and tire brushes, rubber mold cleaning brushes, automotive detail and wheel brushes with rubber elements, banknote counter and motorcycle chain brushes, and rollers with rubber wipers or paddles that move product.
Which rubber should you choose?
- Natural rubber: elastic and grippy, but weak against oils, ozone and sunlight.
- EPDM: water, steam, weather and many cleaners; poor with oils.
- Nitrile: oils, fuels and greases.
- Silicone: heat, cold and food contact; covered on its own page.
How hot can rubber run?
It depends on the elastomer: data quote about -30 to 120°C across common grades. Silicone and some EPDM compounds go higher; natural rubber is lower. Name the temperature and the compound is chosen for it.
Where does rubber fall short?
A page or quote that just says rubber cannot promise anything about chemicals or heat. Without the compound, hardness and compatibility, the result is a guess. Rubber also wears on abrasive surfaces and can take a set under constant compression.
What should you tell us?
The job, the liquids and chemicals, the temperature, the hardness or the existing part, and the profile or blade section.
Questions buyers ask about Rubber
Which rubber is best for a squeegee or wiper blade?
EPDM for water, steam and cleaners; nitrile where oils and fuels are present; silicone for heat or food contact. Hardness is chosen for the surface and pressure.
Why do you ask which rubber I need?
Because rubber is a family. Natural rubber, EPDM, nitrile and silicone react very differently to oils, chemicals and heat.
How hot can a rubber wiper get?
About -30 to 120°C across common elastomers; silicone and some EPDM go higher. Name the temperature.

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.
