Silikon sheet – cut to size

Custom-cut silicone sheets are suitable for seals, supports, insulation and technical applications with high or strongly fluctuating temperatures. Our silicone sheets have a hardness of 60 ±5 Shore A, are temperature-resistant from -60 °C to +230 °C and are suitable for applications with high hygiene requirements. Width and length can be cut individually to the required size.

Custom-cut silicone sheets

Silicone sheets are frequently used as sealing material, protective support, insulation or elastic intermediate layer. With an accurately dimensioned cut, you reduce material waste and avoid additional processing steps in your own operation.

The silicone sheets can be configured individually in width and length. This makes them suitable both for one-off pieces and for recurring requirements in industry and trade.

Typical areas of use are:

• flat gaskets and sealing strips
• mechanical and plant engineering
• food processing
• packaging technology
• laboratory and medical technology
• electrical insulation
• protective and support mats
• thermally stressed components

How temperature-resistant are silicone sheets?

Silicone sheets are particularly suitable for applications with high and low temperatures. The material offered is designed for a temperature range of -60 °C to +230 °C.

Even at low temperatures, silicone remains comparatively flexible. At elevated temperatures, the material is characterised by good resistance to heat ageing.

Typical applications include seals on machines, thermally stressed supports, components in packaging systems or applications in food technology.

Are silicone sheets food-safe?

According to the product specification, the silicone grade offered is intended for applications with food contact in accordance with BfR XV, EC 1935/2004 and FDA 21 CFR §177.2600.

This makes the material particularly suitable for seals, supports and technical components in areas with increased hygiene requirements.

For specific applications, the respective legal and operational requirements should be compared in advance with the available material certificates.

What thickness should a silicone sheet have?

The suitable sheet thickness depends on the load and function of the component.

Thickness	Typical use
1–2 mm	thin seals, intermediate layers
3 mm	flat gaskets, covers, technical supports
4–6 mm	seals, protective supports, elastic intermediate layers
8–10 mm	greater damping and mechanical decoupling
from 12 mm	robust supports and applications with higher material requirements

A silicone sheet with 3 mm thickness, for example, is suitable for numerous general sealing and support applications. For higher mechanical loads or greater compensation requirements, thicker silicone sheets are often used.

Silicone sheet or silicone mat?

The terms silicone sheet and silicone mat are sometimes used for similar products. Thin or particularly flexible cut pieces are often referred to as a silicone mat, while technical semi-finished products tend to be called silicone sheets.

What matters is not the names, but the material quality, Shore hardness, thickness and temperature range.

A custom-cut silicone mat can therefore also be produced by means of an individually configured silicone sheet cut.

Silicone or EPDM: which material is more suitable?

Silicone and EPDM both have good weather and ageing resistance. However, there are clear differences in the service conditions.

Property	Silicone	EPDM
Temperature resistance	very high	high
Cold flexibility	very high	high
UV resistance	very good	very good
Ozone resistance	very good	very good
Food applications	very well suited depending on quality	depending on quality
Hot water/steam	good to very good	very good
Oil resistance	limited	limited
Cost	higher	usually more favourable

Silicone sheets are particularly worthwhile where high temperatures, strong temperature fluctuations or special hygiene requirements exist.

EPDM, by contrast, is often the more economical solution for general sealing and outdoor applications.

Machining silicone sheets

Silicone sheets can be machined in different ways depending on thickness, size and desired contour. Straight cuts can be made on thinner materials, for example, using suitable cutting tools.

For precise component geometries, industrial cutting or punching processes may be worthwhile depending on the requirement.

With a directly ordered custom-cut silicone sheet, subsequent adjustment of length and width is often eliminated entirely.

Properties

Silicone has several properties that distinguish the material from many other elastomers.

High temperature resistance: silicone is suitable for applications in which other rubber materials reach their thermal limits.

Cold flexibility: the material remains elastic even at low temperatures.

UV and weather resistance: silicone has very good resistance to UV radiation, ozone and weather influences.

Electrical insulation: the material can be used for various electrically insulating applications.

Elasticity: silicone can absorb deformation and then largely return to its original shape.

Ageing resistance: the material properties remain comparatively stable even under prolonged stress.

Applications

Mechanical and plant engineering

Silicone sheets are used as seals, intermediate layers, supports or thermal insulation. Applications with fluctuating or high temperatures are particularly relevant.

Food industry

Thanks to the material quality intended for food contact, silicone sheets are suitable for numerous applications on processing and packaging machines.

Laboratory and medical technology

Silicone is used wherever elasticity, temperature resistance and hygienic properties must be combined.

Electrical engineering

Due to its electrically insulating properties, silicone can be used as a protective and insulating material.

Vehicle and device technology

Silicone sheets are suitable for temperature-stressed seals, covers and elastic intermediate layers.
