Silicon rubber cap

Silicon rubber cap

Silicon rubber cap is one of the many types of caps and plugs that you can buy from us. Some caps differ in shape and size, and some in material, such as silicon rubber cap. A silicone or polysiloxane is a polymer that is colorless and odorless. It performs especially well when in contact with water or other fluids, such as petroleum fluids. Another fantastic feature of silicone is the temperature range at which it can operate. It can operate from – 80 degrees Celsius to over plus 250 degrees Celsius. Silicone can even withstand temperatures below minus 110 degrees if exposed to such low temperatures for a short time. Its tear resistance is significantly weaker compared to natural rubber, but the chemical stability is excellent, making it ideal for contact with food and beverage. The silicon rubber cap has all these characteristics as well, so you now understand for what purposes silicon rubber cap is best.

The purpose of the silicon rubber cap is very diverse. They are used as protections during production, storage and transportation. Many components can be easily damaged during transport, and rubber caps will effectively protect them. Caps are often used for masking, when welding or painting, and a certain part should be protected. It can also be used for product finishing.

For whatever purpose you are using it, size is very important. For example, if you use rubber caps for masking, and the size is not appropriate, paint will end up on the part that needs to be protected and the like. So our advice is to be very cautious when ordering a size, and to choose the right size, you need to measure each part carefully. Then the silicon rubber cap will fulfill its duty and you will know that the part you want is completely protected.
