Butyl Rubber Seals

Advanced Seals & Gaskets Ltd offers a diverse range of electrical insulation products, including Mylar pads, to meet the specific needs of various industries. Mylar, also known as BoPET (Biaxially-oriented polyethylene terephthalate), Melinex, and Hostaphan, is a polyester film renowned for its electrical insulation properties. These thin, flexible films, measured in microns rather than millimeters, come in a range of thicknesses from 12 to 500 microns and are manufactured in roll form. This allows us to cut these rolls into sheets or custom-made components, such as pads, gaskets, washers, and strips, tailored to the unique dimensions provided by our customers.

Mylar, being a heat-resistant polyester film, is designed to provide excellent dielectric strength and resistance to moisture and various chemicals, except alcohol. It remains flexible, strong, and durable under normal use conditions. Additionally, Mylar's temperature range, spanning from -70°C to +150°C, makes it a versatile choice for a wide range of applications. The material's white color and excellent moisture and chemical resistance contribute to its appeal in various industries.

Customers can choose from square or rectangular pads, which can be customized with or without radius corners, as well as circular or oval-shaped pads. These Mylar pads can be ordered in various thicknesses and in plain or self-adhesive finishes. Mylar is widely used for cable insulation, heating elements, solar panels, motors, aerospace applications, and more, making it a highly versatile electrical insulation material. The rough surface of Mylar aids in handling, conversion, and adhesion, which is beneficial for various applications.

We offer our customers the flexibility to order pre-cut Mylar pads or rolls of material that can be further converted into components as needed. Mylar provides an excellent solution for applications requiring electrical insulation, whether in standard sizes or tailored to specific requirements. With its unique combination of properties, Mylar is a trusted material across various industries, from electronics to packaging and beyond.

Collaborating with multiple manufacturers and suppliers, Advanced Seals & Gaskets (ASG) offers a diverse selection of solid rubber seals. Among these, solid butyl rubber, also known as Isobutylene-isoprene

Seals constructed from Solid Butyl rubber offer a host of exceptional properties and characteristics. This flexible material retains its flexibility even at low temperatures, boasting an impressive operating temperature range spanning from -40°C to +140°C. It's pre-manufactured in various thicknesses, ready to serve as liners or for conversion into gaskets, washers, or molded into pipes, O-rings, and other customized sealing profiles.

Solid Butyl rubber stands resilient against degradation caused by UV exposure, weathering, heat, moisture, and certain acids and alkaline chemicals. Its structure exhibits impermeability to gas and compressed air, making it an excellent choice for applications involving air retention. This quality is vital for creating seals in inner tubes, vacuum sealing, tubeless tires, sports-ball bladders, and even in the production of gas masks. Moreover, Solid Butyl rubber serves well for a multitude of waterproofing needs, both indoors and outdoors, including pond and tank seals, liners, and roofing fittings.

is a prominent material choice.

ASG provides top-quality solid butyl rubber seals in various configurations, such as gaskets, washers, O-rings, mouldings, and extrusions. These seals serve the vital purpose of preventing leaks and inhibiting the ingress of air, fluids, and gas, while also offering insulation and protection. Every seal is custom-made to meet specific requirements, based on customer-provided samples or drawings, ensuring a precise fit for the intended application.

Manufacturing these seals requires distinct processes for each type, and ASG has made substantial investments in various machinery. This enables the production of various seal types in both high and low quantities, ensuring flexibility and adaptability to customer needs. The emphasis on high-quality materials and precise manufacturing makes ASG a trusted source for solid butyl rubber seals across industries and applications.

    What Are Solid Butyl Rubber Seals?

    The term 'seal' encompasses various product forms, including cut gaskets, strips, washers, extruded or molded profiles, and edge trims. These components serve as precise gap fillers between surfaces, acting as effective separators or barriers to prevent the escape or penetration of liquids, particles, or gases. They find utility in a range of applications related to vibration damping, sealing, and insulation.

    Solid Butyl rubber is a synthetic rubber compound formed by blending isobutylene with isoprene, resulting in a unique structure known as Polyisobutylene (PIB). PIB exhibits impermeable properties ideal for air retention and gas sealing applications. However, it is not recommended for use with petroleum, oils, or chlorinated solvents due to its limitations in compatibility.

    Why Use Solid Butyl Rubber Seals?

    Seals manufactured from Solid Butyl rubber are a common choice for demanding applications involving high-pressure gases, such as compressed air pipelines, air retention, and high-pressure vacuum sealing. Butyl rubber stands out due to its exceptional thermostable properties, coupled with its resistance to weather and ozone, making it suitable for both internal and external applications.

    The material exhibits flexibility and offers robust resistance against issues like flex cracking, abrasion, impact, and tear. Its low gas and vapor permeability render butyl rubber indispensable in various uses, including the production of gas masks, applications in roofing construction, utilization as vibration-absorbing shock mounts and bushings, sealing for windows, and within hydraulic systems.
