What is Solid Rubber?
Solid rubber has almost all the same properties as foam rubber except without the cushion created by air. Rubber of all types is very versatile as it carries natural resistant properties, but can also be treated for use in specific industries.
Why use Solid Rubber?
The use of solid rubber materials are used in shock absorbers, truck bumpers, and anti-vibration pads for vehicles, machinery, and equipment. These industrial rubber products reduce the risk of downtime by protecting mechanical parts.
Advantages of Solid Rubber?
Solid Robber has many advantages including its density, rigidity and force distribution.
Disadvantages of Solid Rubber?
Rubber has disadvantages including its sturdiness and performance efficiency when compared to other potential materials.
MF775 solid Silicone rubber is a highly non-flammable and fire safe material, approved to BS6853, EN45545-2 and UL94 approved to V-0 and HF-1.
In addition to these properties, MF775 also maintains good resistance to UV and ozone, combined with resistance to extremely low and high temperatures, making it ideally suited for outdoor use.
Most commonly, MF775 Silicone rubber sheeting is used for applications in the mass transit industry. It is approved by and widely used within the London Underground system

CB Frost are a UK preferred convertor of the BISCO range of Silicone-based foams and rubbers and have a relationship with Rogers Corporation extending over 30 years.
HT200 (Sound Block) Silicone rubber materials are specifically designed to reduce the transmissions of sound within interior space and preventing the spread of fire and smoke. The elastomeric materials use a filler technology to solve acoustic, fire and smoke issues within a variety of markets.
They are supplied in roll form and are available with or without adhesives and supported backings to aid in your installation on various surfaces, wall panels, doors, flooring, and ducting.
Applications
- Sub-flooring for railcars
- Interior vehicle panels
- Air ducts
Installation
- Available with a pressure-sensitive adhesive on one or two sides to allow easy application to a variety of
surfaces. - Also available with a fibreglass backing on either side of the product at no extra charge to allow users a
variety of options for installation. The fibreglass backing enhances the strength and tear resistance of the
material, which allows users to mechanically attach the Sound Block to various surfaces such as carpet or
steel without sacrificing the integrity and durability of the BISCO Sound Block material.
Design Considerations
BISCO Sound Block may be applied and used in various forms. Please contact +44 (0) 121 773 8494 for further
assistance or samples.

Nitrile Rubber is a synthetic rubber co-polymer of acrylonitrile and butadiene..
Also known as Buna-N or NBR, Nitrile rubber is resistant to aliphatic hydrocarbons, oils, and fuels; and has a temperature range of -20 ˚C to + 70˚C. Nitrile Rubber is similar to commercial and natural rubber, as it can be attacked by UV/Ozone. Nitrile is widely used in the aeronautical, petrochemical, and automotive industries as O rings, gaskets, and seals.
It exhibits an impressive resistance to water-based chemicals as well as vegetable based hydraulic oils.
Nitrile rubber can be supplied in a selection of different grades depending on your requirements, including commercial, BS2751 (British Standard) and food grade specifications.

Commercial Rubber, or SBR Rubbers, exhibit excellent physical properties, for example, good tensile strength, low compression set and high tear properties.
Whilst Commercial Rubber has a high resistance to abrasion, it tends to degrade much quicker when subjected to contact with UV and ozone, so commercial and insertion rubber gaskets are not ideal for outdoor use.
Commercial rubber offers an excellent economical alternative to other grades of rubber materials including Neoprene, EPDM and Silicone. With prices of Commercial rubber tending to be much more competitive in price, Commercial/Insertion rubber gaskets provide a cheaper option for a wide variety of applications. In addition to the benefits in terms of cost, Commercial rubber gaskets can also be supplied in a selection of grades including BS1154, shore hardness (40 to 80 shore A, depending on grade), and in a good range of thicknesses.

Commercial Insertion rubber is mixed with other polymers as a method of keeping costs to a minimum.
An economy grade 70 shore A rubber with a single ply polyester insertion makes it ideal for use as vehicle mud flaps, door skirts/draught excluders, work top counters and general gaskets.
CB Frost hold stock in a range of thicknesses on the shelf, from 1mm up to 6mm. Rolls are 1.4mtrs wide by 5 or 10mtrs long depending on thickness.
This grade (1 ply) cannot be extruded or moulded into shapes/gaskets.
There are no European or International standards that SBR insertion rubber sheeting is required to meet, and it is not Food safe.

Fine Fluted Ribbed Matting is a 65 shore A rubber that has narrow ribs running down the length of the roll and a cloth mark surface on the reverse side.
The narrow strips give the material a non-slip surface, making it suitable as floor covering for temporary or semi-permanent use in industrial and commercial areas, horse boxes, steps, ramps, pickup and van load beds and tool top boxes.
CB Frost stock Fine Fluted Ribbed Matting at 3mm and 6mm thick. Rolls are either 915mm, 1mtr or 1.22mtrs wide x 10mtrs long.
