High-temperature tapes are a type of specially engineered adhesive tape used in electrical applications with excessively high temperatures. High-temperature tapes serve a dual purpose – not only do they provide much needed electrical insulation, but they are also resistant to temperatures in excess of 500o F. These tapes are especially crucial in cable terminations and splicing in several applications ranging from electronic circuit board protection to high-voltage power lines. In addition to operation in high-temperature environments, these tapes offer significant chemical resistance and superior tensile strength.
Robert McKeown Company, Inc. provides a wide range of tapes for use in a range of demanding applications across numerous industry leading manufacturers.
High-temperature tapes are designed to prevent failures associated with environments that display extreme operating temperatures. They are typically manufactured from thermally resistant PTFE, glass cloth, rubber, polyamide, and several types of composite materials. Various industries have different requirements; therefore, appropriate material and grade selection are essential to ensure that the tape performs effectively under the given thermal demand.
One of the primary modes of failure by tapes in high-temperature environments is the loss of adhesion. Furthermore, poor tape performance has also been linked to material deterioration and dimensional instability in extreme situations. As temperatures increase, most tapes tend to undergo warping and shrinkage, which further contributes to adhesion loss. The materials used in the fabrication of high-temperature tapes exhibit excellent thermal resistance, causing the tape to retain its adhesion and physical properties even when exposed to high temperatures.
At Robert McKeown Company, Inc., our selection of high-temperature electrical tapes are capable of maintaining high levels of adhesion to a wide range of substrates in environments that would otherwise be unsuitable for more common types of tapes. Excellent resistance to oxidation and other forms of chemical attacks make our solutions ideal for corrosive environments, which tend to cause chemical deterioration in unsuitable tape materials. Some of the primary features of our high-temperature tapes include:
- Excellent adhesion at extreme temperatures
- Flexibility and ability to conform to irregular shapes
- Adhesion to a wide range of surfaces
- Excellent dielectric properties
- High levels of thermal resistance (up to 500o F/260o C)
- Tear/puncture resistance
- Resistance to a variety of harsh solvents
Despite their dielectric properties, high-temperature tapes can also be used in a wide range of industries outside the electrical and electronic fields. In fact, any industry where reliable and durable bonding solutions are required can benefit from the unique properties of these tapes.
The uses of high-temperature tapes are highly diverse. Some typical applications across various industries include:
- Automotive – Bonding and splicing of wires in vehicle engines
- Electronics – Used in electrical boxes, conduits, and other fittings
- Consumer goods – Bonding of cables and wires in a wide range of appliances
- Medical – Bonding and protection of surgical and medical equipment
- Power generation – Used for gasketing, sealing, and insulation applications
High-temperature tapes are available in a variety of sizes, compositions, and grades. Selection of the appropriate tape for your specific application is crucial to ensuring proper long-term bonding performance. At Robert McKeown Company Inc., our extensive inventory of high-temperature electrical tapes offer solutions to satisfy the needs of even the strictest customer demands.
