Cork insulation tape

Types of cork insulation tape

There are various cork insulation tapes; each one varies in usage, thickness, and adhesive type, ensuring optimal thermal, acoustic, and vibration protection across multiple industries. Here are some common types:

• Standard cork insulation tape

  This is a very general-purpose tape made with a base layer of cork and uses a rubber adhesive system. Because of its high insulation performance, it is mostly utilized on pipes, ducts, and equipment in a facility. Its thickness can differ, often around 1/8 inch, enabling it to stretch around awkward surfaces while still offering solid cork thermal insulation tape properties.

• Corked rubber insulation

  Cork rubber insulation tape is a mixture of cork and rubber compounds. Because cork blocks serve separate purposes as thermal insulators and noise suppressants, this kind of tape is particularly helpful in bright, mission-critical environments looking for greater insulation. Apart from the broad scope of its adhesive style, cord rubber insulation tape differs from the standard cork insulation tape regarding its thickness and surface.

• Self-adhesive cork insulation tape

  This sort of tape includes a peel-and-stick backing for easy application with no additional adhesive elements. Self-adhesive cork insulation tape is broadly applied for temporary fixing or situations where quick application is required without the additional need for tools. This tape generally has a thickness of around 2mm, which fits flushing with a surface yet provides excellent insulation and cushioning.

• Expanding cork insulation tape

  Expanding cork insulation tape was created to provide a perfect seal around pipes and ducts in enhancing insulation. This tape's core is made from cork and will expand once exposed to heat, thus filling any gaps or fissures. Expanding cork tape is useful in environments that possess high temperatures or where insulation failure can generate enormous energy losses. This tape usually has increased thickness and comes with a distinct adhesive backing that continues to hold well in high-heat conditions.

• High-temperature cork insulation tape

  This insulation tape is highly effective at cork and rubber thermal insulation, which is unaffected by heat. Usually, this tape is made from silicone adhesive and standard cork withstanding over temperatures of around 500°F. Seamlessly integrate this tape into any mechanical job in an automotive or aerospace company, where insulation is critical under high heat. Tape thickness often ranges at about 1/16 inches, making it very flexible for insulation purposes.

Design of cork insulation tape

The cork insulation tape contains cork, which features a porous and compressible nature, allowing it to serve as an effective insulator against temperature, sound, and vibration. The pores in cork are microscopic and air-filled, providing thermal resistance. That's why cork holds heat or cold. Apart from that, the compressibility also enables cork to absorb vibrations efficiently.

The cork is combined with rubber or some other adhesive when designing the cork insulation tape. Rubber is used because it possesses good elasticity, weather resistance, and adhesive properties. The rubber core can also be filled with microscopic air bubbles during the manufacturing process to enhance its insulating efficiency. Air bubbles are tiny pockets of trapped air within the rubber. These act as additional insulating layers similar to how cork functions. The outer layer or backing of the insulation tape is usually a very thin rubber layer to protect the cork or cork rubber from harsh or damaging environments. This layer also ensures the tape has a smooth finish and can be applied to adhesive surfaces easily.

The adhesive system is one of the major factors that drive the performance of cork insulation tape. Different adhesives have distinct properties and purposes. For instance, rubber adhesives are versatile, with excellent adhesion to multiple surfaces and environments. Silicone adhesives, on the other hand, are designed to withstand higher temperatures due to high and low temperature stability. Cork insulation tape is designed in various thicknesses, usually ranging between 1/16 inches to 1/8 inches. Thicker tapes provide better thermal barriers and cushioning. At the same time, thinner options offer flexibility and easier application to curved or irregular surfaces.

Lastly, cork insulation tape is often treated with a protective finish or sealant. This helps enhance the tape's durability properties by minimizing moisture absorption, protecting from chemicals, or blocking out air to promote enhanced insulation properties.

Scenarios of cork insulation tape
