Flexible Silicone Sheeting for Demanding Applications

Black Silicone Rubber 40 Shore A is a softer, more flexible silicone sheeting option designed for applications where compression, sealing contact, and material adaptability matter. Compared with harder silicone grades, the 40 Shore A hardness gives the sheet a more pliable feel, making it useful for sealing, lining, gasket cutting, and general technical rubber work.

This grade is described as FDA approved, making it suitable for buyers who need silicone material where food-grade suitability or compliance-led selection is part of the buying decision. It is also built for demanding environments, with strong resistance characteristics and reliable performance in heat, flame, ageing, and weathering conditions.

Why Choose 40 Shore A Silicone Rubber

The 40 Shore A hardness rating makes this material softer than many standard industrial rubber sheets. That softness is useful where the rubber needs to compress more easily against a surface or form a tighter seal under pressure.

For gasket work, washers, strips, and cut sheet components, this grade can be a practical choice when a firm material may not provide enough surface contact. It gives users a balance of flexibility and resilience without becoming too delicate for regular handling or fabrication.

Heat, Weathering, and Ageing Performance

This black silicone sheet is made for more demanding use than basic general-purpose sheet materials. Its resistance to heat and flame makes it suitable for environments where temperature performance is an important consideration. It also offers good ageing and weathering characteristics, helping it remain practical in conditions where exposure, movement, or changing environments may affect lower-grade materials.

The smooth finish supports easier cleaning and gives the sheet a neat surface for cutting, lining, and sealing applications. This is useful when the finished component needs to sit cleanly against a surface or form part of a more technical installation.

Chemical and Environmental Suitability

This material is listed for use around a wide range of substances, including acetic acid, AdBlue, brine, calcium chloride, carbon dioxide, carbon monoxide, carbonic acid, sodium hydroxide, citric acid, formaldehyde, glucose, hydrogen gas, hydrogen peroxide, hydrogen sulphide, lime, methyl alcohol, methanol, neon gas, nitrogen, ozone, phosphoric acid, potassium carbonate, sea water, sewage, sodium peroxide, steam, transformer oil, urea, vegetable oil, and vinegar.

For any sensitive or regulated application, the final choice should be checked against the exact operating conditions, including temperature, pressure, exposure duration, concentration, and whether the material will be used in static or moving contact.

Frequently Asked Questions

What does 40 Shore A mean?

40 Shore A describes the hardness of the silicone rubber. This grade is softer and more flexible than higher Shore A options, making it suitable for sealing, gasket cutting, and applications where compression is important.

Is this black silicone rubber FDA approved?

Yes, this silicone rubber is described as an FDA approved grade. It is suitable for buyers who need material where food-grade suitability or compliance-based selection is part of the requirement.

What thickness options are available?

This material is available from 1.0mm to 10mm. Thinner sheets are useful for lining and light sealing work, while thicker options can provide more substance for gaskets, strips, and technical cut parts.

Can this silicone sheet be cut to size?

Yes, the material can be cut using standard press-tools. It is suitable for producing strips, washers, gaskets, seals, and custom-cut shapes depending on the required dimensions.

Is 40 Shore A suitable for gasket making?

Yes, 40 Shore A silicone rubber is suitable for gasket applications where a softer, more compressible material is required. It can help form better contact against surfaces compared with harder rubber grades.

Does this material have good weathering resistance?

Yes, this grade is described as having very good ageing and weathering characteristics. It can be suitable for demanding environments, provided the exact working conditions match the material specification.

Can other colours or finishes be supplied?

Other grades, colours, and finishes may be available, but they are subject to minimum batch quantities. Availability should be checked before ordering if a specific finish or colour is needed.

Cutting and Fabrication Options

The sheet can be cut using standard press-tools, making it suitable for creating accurate components from roll material. It can be prepared as strips, sheets, washers, seals, gaskets, and other custom-cut parts depending on project requirements.

The 1.2m roll width gives flexibility for both larger sheet coverage and smaller cut components. With thickness options from 1.0mm to 10mm, users can choose the material depth that best matches the sealing, lining, or protection requirement.
