What are the specifications of automotive-specific tapes?
2 Answers
Automotive-specific tapes include PVC tape and fabric tape. PVC tape: PVC tape, fully known as polyvinyl chloride electrical insulation pressure-sensitive adhesive tape, has a base material of soft PVC film and an adhesive layer primarily composed of natural rubber, acrylic adhesive, or synthetic rubber. PVC tape exhibits excellent characteristics such as temperature resistance, cold resistance, corrosion resistance, oil resistance, and flame retardancy. Fabric tape: Fabric tape, also referred to as PET tape, commonly includes the following types: fiber fabric tape, polyester fabric tape, wool-polyester fabric tape, flannel tape, felt tape, electrical insulation waterproof tape, and non-adhesive fabric tape. The typical color of fabric tape is black, with a thickness generally ranging from 0.25-0.8mm.
In my DIY car projects, I often use automotive-specific tape, which comes in various specifications, with size being a key factor. Common widths like 19mm or 25mm are suitable for general sealing, while 50mm wide tape works well for securing larger parts. The length is typically 10 meters or 20 meters per roll, minimizing material waste. The material is mainly PVC, with a thickness of about 0.15mm, providing resistance to stretching and tearing. Temperature range is crucial—it must withstand lows of -40°C and highs of 120°C, making it suitable for use near the engine or in cold regions. Adhesive strength is generally above 100 N/m² to ensure parts stay secure. Black is the most common color, as it absorbs less heat for better stability. When purchasing, check the brand and specifications—avoid using regular tape to prevent failure under high temperatures, which could lead to minor issues. In summary, size and heat resistance are the priorities; measuring carefully before use saves time.
