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.
