Sealing Capabilities of Red Silicone Rubber Washers.
Our Red Silicone Rubber is a premium-quality, industrial grade Silicone Rubber Sheet with excellent sealing properties. This rubber has excellent temperature resistance, very good electrical insulation properties and wide-ranging chemical resistance. These, and other properties, are expanded on more below:
Food Grade and Potable Water Approved.
Washers and seals cut from our Red Silicone Rubber inherit this materials food and potable water certification. Red Silicone Rubber Washers from Swift are made from food grade rubber which allow them to be used in sealing equipment that will have direct contact with food (as per FDA and EU standards) and for sealing potable (drinking) water (as per WRAS).
This rubber also carries certifications for several other applications which are detailed more on the attached technical data and over on the specifications tab.
Excellent Heat and Cold Temperature Resistance.
Seals made from our Red Silicone Rubber will withstand ongoing exposure to temperatures between -60°C and +230°C as well as short-term spikes to 250°C.
This is important as most other rubbers (Viton/FKM is the other exception) simply will become brittle and crack well before -50°C and will exhibit serious degradation before 160°C. Silicone doesn't and maintains excellent flexibility and sealing performance. An important attribute for high or low temperature seals.
Excellent Sealing Characteristics.
Silicone Washers are Seals are often selected because of this rubber excellent sealing performance. All the washers featured on this page are made from 60 Shore A Durometer Rubber sheet and have excellent compression, recovery and mechanical strength.
This results in washers which are very long lasting and offer reliable sealing performance.
