Solid Butyl Rubber

Advanced Seals & Gaskets supply a diverse range of solid rubber materials, one of which includes solid butyl rubber, also known as Isobutylene-isoprene (IIR).  Solid butyl rubber is manufactured in roll form at thicknesses starting from 1mm, and at 1.4 meters wide x 10 meters long, which can be supplied in roll or sheet form, or as finished cut parts.  

As we carry out all our conversion on-site, we can cut these rolls down to produce usable products including gaskets, washers, pads or strips, using one of our many states of the art machines such as presses, kiss-cut presses, log cutters, bandsaws or CNC machines. Solid silicone rubber can also be used to produce tubes, mouldings and extrusions. 

What is Solid Butyl Rubber?

Solid Butyl rubber is a synthetic rubber made up by blending isobutylene with isoprene, this creates a property known as Polyisobutylene, commonly known as PIB.

This material offers many desirable properties including excellent thermal stability and resistance to UV and weathering, it also has an impermeable structure required for air retention or gas sealing applications, but is not recommended for use with petroleum, oils or chlorinated solvents. 

Solid butyl can be supplied as pre-cut parts such as washers, strips and gaskets, or taken as full sheets and rolls, giving customers the flexibility to convert them into a range of usable products as and when required.

    Why use Solid Butyl Rubber?

    Solid butyl rubber is frequently used in demanding applications that involve high-pressure gasses such as compressed air pipelines, air retention or high-pressure vacuum sealing. Butyl rubber is known for its thermostable properties which partnered with the weather and ozone resistance make butyl it excellent for both internal and external use.

    The material is flexible with good resistance to flex cracking, abrasion, impact and tear.  Due to its low gas and vapour permeability, butyl rubber is an important material in the manufacturing of tubeless tires, inner tubes, sports-ball bladders and used in making gas masks,  It can also be utilised as a waterproofing material as pond and tank liner or roofing membranes and as vibration impending shock mounts and bushings.

    Other Types of Solid Rubber Available:

    • Neoprene
    • EPDM
    • Silicone
    • Polyurethane
    • Nitrile
    • Hyalon
    • Insertion Rubber
    • Shotblast

    Benefits of Solid Butyl Rubber

    • UV & Ozone resistant
    • Impermeability To Gases compressed air and moisture 
    • Shock and anti-vibration properties
    • Wide operating temperature range
    • Excellent sealing properties
    • Flexible with resistance to Flex cracking, abrasion tear and impact

    Advantages of Using Solid Butyl Rubber

    Solid butyl rubber offers many advantageous properties, characteristics and uses.  It’s a flexible material even at low temperatures with a wide operating temperature of  -40°C to +140°C and is pre-manufactured in a range of thicknesses ready for use as liners or for converting into gaskets and washers or moulded into pipes, o-rings and other bespoke profiles. 

    Solid Butyl resists degradation caused by UV, weathering, heat, moisture and some acids and alkaline chemicals.  Its structure is impermeable to gas and compressed air, making it an excellent choice for air retention, therefore creating gas and air seals inner tubes, vacuum sealing, tubeless tyres, inner tubes, sports-ball bladders and in the production of gas masks. 

    It can also be used for a range of indoor and outdoor waterproofing purposes such as pong/tank liners or roofing membrane.  Solid Butyl rubber can be manufactured as mouldings, extrusions or in sheet and roll for use as liners or to be cut into other products, many of which can be supplied with a self-adhesive or foil backing.
