Silicone rubber sheets based on VMQ silicone rubber provide a stable and reliable industrial solution for applications requiring a combination of high flexibility, thermal resistance, chemical inertness, and compliance with food-contact standards.
Sheets in stock are supplied in rolls with a width of 1200 mm, in thicknesses ranging from 0.3 mm to 12 mm, and are sold by the linear meter, allowing material savings, precise purchasing, and full compatibility with manufacturing processes.
The material is suitable for both serial production and one-off applications, while maintaining consistent properties over time.
Main Engineering Characteristics
Standard hardness: 50–60 Shore A
Thickness range in stock: 0.3–12 mm
Roll width: 1200 mm
High elastomeric flexibility, even in thin gauges
High thermal stability – does not harden or degrade with temperature changes, self-extinguishing (UL94)
Excellent resistance to aging, UV, and ozone
Chemical inertness to most commonly used substances
Approved for food contact (Food Grade)
Suitable for static sealing and light dynamic sealing applications
Clear Industrial Advantages
Material does not “flow” or change properties over time
Retains flexibility even after years of service
Easy to clean – does not absorb odors or contaminants
Suitable for wet, dry, and clean environments
Can be integrated into existing production lines without special modifications
Available from stock in common thicknesses, with the option for custom orders
Typical Applications
Food and beverage industry
Processing equipment, conveyors, and production lines
Gaskets, separation sheets, and partitions
Pharmaceutical and biotechnology industries
Laboratories, ovens, and testing equipment
Thermal and electrical insulation
Technical cut parts for OEM machinery
Damping and separation solutions between assemblies
Customization and Production on Demand
Beyond the standard specification, the following options are available:
Alternative hardness levels (softer or harder)
Custom material formulations according to operating conditions
Special, non-standard thicknesses
Compliance with specific regulatory requirements
Small-batch or serial production
Cutting and Processing
Sheets can be supplied as full rolls or processed to specification:
Cut-to-size sheets
Precision digital cutting (Knife / CNC / Waterjet, depending on application)
Manufacturing of gaskets, strips, rings, and complex shapes
Production according to drawing, DXF file, or physical sample
The precision of processing allows direct use on the production line without additional finishing by the customer.
