If you have ever taken your car to a mechanic and watched him/her perform repairs, you have most likely noticed them wrapping certain parts of the car with tape or another material. While it’s not something that would be particularly interesting to most, it’s actually quite important. This tape – and other materials like glue or sealant – are used to prevent or control leaks in different parts of the vehicle and keep them intact, thus making sure the car remains functional and doesn’t lose its value over time due to damage caused by leaks or other factors. This article provides a brief introduction on the different types of adhesive tapes used in automotive industry along with the benefits of using each type.
Adhesive tape – an overview
Most people are familiar with adhesive tape from its common household uses, such as sealing envelopes or wrapping presents. But did you know that adhesive tape plays an important role in the automotive industry? In fact, there are different types of adhesive tapes specifically designed for use in cars, trucks, and other vehicles. Each type of tape has its own unique benefits that make it ideal for different applications.
Self-adhesive based tapes
There are different types of self-adhesive based tapes available on the market, each with its own set of benefits. Some of the most popular types include: acrylic foam tape, double sided tape, transfer tape, and VHB tape. Acrylic foam tape is usually made from a polyester fabric coated with a pressure sensitive adhesive. They have a long lifespan and can provide good moisture resistance for automotive applications. Double sided tape consists of an adhesive layer on both sides to ensure secure bonding to various surfaces, including metal, plastic, rubber, paper, or glass. Transfer tape is made up of one side coated with an adhesive to adhere materials together while the other side provides protection from moisture or chemicals that could potentially damage the surface being adhered to. Lastly, VHB (very high bond) tapes provide an even stronger hold than regular tapes due to their thicker construction and larger amount of adhesive material per square inch.
Mechanical bonding based adhesive tapes
Silicone rubber tape
Another popular type of adhesive tapes used in automotive industry is silicone rubber tape. As the name suggests, this tape is made of silicone rubber, which is a synthetic rubber that is heat resistant and has excellent electrical insulation properties. This makes it ideal for use in cars, where it can withstand high temperatures and protect against electrical shocks. Silicone rubber tape is also very flexible, making it easy to apply to uneven surfaces. It is available in different widths and thicknesses.
Polyurethane (PU) foam tape
PU foam tape is a type of adhesive tape that is made from polyurethane. This material is known for its excellent moisture resistance, making it ideal for use in automotive applications. PU foam tape can be used to seal doors, windows, and trunks, as well as to secure exterior trim pieces. It can also be used to dampen noise and vibration. PU foam tape is available in a variety of thicknesses and widths, making it easy to find the right product for your needs.
Pressure sensitive adhesive tape
There are many different types of pressure sensitive adhesive (PSA) tapes used in the automotive industry, each with its own benefits. Double-coated tape is often used to attach trim and molding, while acrylic foam tape is used for weather-stripping and sealing. PSA tapes can also be used for wiring harnesses, interior paneling, and exterior applications. When choosing a PSA tape, it’s important to consider the type of surface it will be applied to, the temperature range it will be exposed to, and the amount of time it will need to stay in place.
