Silicone Rubber Translucent
Silicone Translucent is a silicone sheet material used for the manufacturing of silicone flexible sleeves, and silicone cut gaskets.
Filcoflex offers a wide range of silicone flexible sleeves and silicone cut gaskets in translucent silicone. Silicone flexible sleeves, and Silicone cut gaskets can be made in various thicknesses.
Filcoflex custom makes silicone flexible sleeves in round, rectangular and many other shapes to customer specifications. Silicone cut gaskets can be cut from sheet using cutting machines, water jet cutting, or by punching.
Silicone rubber is a semi-organic synthetic made from sand and alkyl or aryl halides. While silicone rubber looks and feels like organic rubber, it has a completely different type of structure than other elastomers. Silicone rubber consists of a chain of silicon and oxygen atoms rather than carbon and hydrogen atoms as found in other types of rubber. This structure gives silicone rubber a very flexible but weak chain. Silicone’s structure also provides a material that has very small change in dynamic characteristics over a wide range of temperature.

- Silicone has a broad temperature range and is generally odorless / non-toxic.
- Silicone offers excellent resistance to high temperatures, ozone, oxygen, UV light, moisture, and fungus.
- Silicone also has excellent vibration damping and maintains its dielectric strength.
- Silicone has low compression set and offers good fatigue resistance, flex resistance, and elongation.
- Silicone offers excellent resistance to Corona discharge, Cosmic radiation, Ionizing radiation, and weathering in general.
- Silicone has an excellent resistance to CIP cleaning and Cleaning Chemicals.
- Standard Silicone sheet materials have a poor tear resistance.
(Filcoflex offers a special silicone sheet material quality called PKSR that has a knitted polyester mesh to improve tear strength by 200%.)
- Silicone has poor resistance to most concentrated solvents, concentrated acids, concentrated alkaline, oils, fuels, hydrocarbons, and steam.
- Silicone may become porous to high concentration fatty substance such as coffee oil at higher temperature applications (above 70° C/158° F).
For a detailed chemical resistance, we advise you to please see our chemical compatibility chart.
Pressure Resistance for Flexible Connectors
0,34 Bar / 5.0 PSI For temperatures up to 90 °C / 195°F. Please see “Operating Pressure Guide” for further information. We recommend using the shortest possible connector for applications where increased pressure and/or high temperature is expected. Please contact us for more information.
High volume weight and capacity weighing, and dosing applications please see “weighing and dosing guide” for further information.
ATEX & Explosion Safety
Silicone translucent sheet is very restricted in how it can be used as a silicone flexible sleeve in explosion hazardous environments. Silicone translucent sheet has not yet been assessed in how it can be used in an ATEX environment.
Alternative material in ATEX environments:
- Filcoflex offers a special silicone sheet material called PKSR for the manufacturing of silicone flexible sleeves, a silicone sheet with a polyester mesh ply reinforcement to improve the tear strength for short pressure bursts and tensioning of vibratory equipment.
- PKSR has been tested extensively for its electrostatic properties and an elaborate assessment provide a lot of information about the restrictions of use in explosion hazardous environments containing explosive dust and air mixtures.
- PKSR provides the benefits of a silicone sheet material and the improved tear strength combined with a elaborate knowledge how to apply it with in the restrictions of an ATEX environment.
