Creates a strong, seamless, waterproof and electrically insulating layer.

Electrical tapes are typically made with a polyvinylchloride (PVC) backing and a non-corrosive rubber-based adhesive. The backing is what gives it the ability to stretch and conform to cables and wiring. This stretch is a critical characteristic of electrical tapes because it allows the tape to wrap tightly around cables for long-lasting insulation. Most cloth, film, and other types of tapes do not possess the elongation characteristics that allow electrical tapes to function properly.

Polyethylene tape is a type of plastic tape made from a polyethylene film backed with a rubber adhesive. Polyethylene film is made from a thermoplastic polymer made from the polymerization of ethylene gas. A rubber adhesive is added to the polyethylene film to make a strong tape that is durable and versatile.

You should use a minimum of two half-lapped layers of vinyl tape to insulate and jacket low-voltage components. A half-lap (see Figure above) consists of overlaying each turn by one-half the width of the tape. The general rule of thumb calls for a tape thickness of 1.5 times the thickness of existing wire or cable insulation. In every case, tension on the tape should be sufficient to conform the tape evenly to the surface. A slight reduction in tension is encouraged for the final wrap. Trim the tape end and allow it to return to shape before pressing down with the thumb to avoid lifting or flagging.

Additionally, butyl rubber is a preferred material for environmentally conscious companies. Its production process typically has a lower environmental impact compared to natural rubber, as it does not rely on extensive agricultural practices. Furthermore, the durability and longevity of butyl rubber rolls contribute to sustainability, reducing waste over time.

The most basic function of a hydraulic pump is to control the movement of pressurized hydraulic fluid. Typically, this fluid is pressurized by a motor, pumped out of a reservoir and travels through bidirectional valves, creating pressure and controlling the movement of hydraulic-powered machinery.

First, let’s talk about the product itself. Flex Tape comes in various sizes and colors, but the white 4” x 5’ version is particularly useful for a range of applications. The tape features a thick, rubberized backing that promises to conform to any shape, thereby creating a permanent, waterproof seal. This characteristic makes it ideal for both indoor and outdoor uses.

Follow up this first step by wrapping four half-lapped layers of rubber insulating tape over the cambric tape, which creates a moisture barrier and provides the primary insulation in the connection. Finally, over-wrap the assembly with a minimum of two half-lapped layers of vinyl electrical tape. This should extend approximately two tape widths beyond the ends of the rubber tape. Stretch this tape as you wrap it so you get good conformance to the underlying structure. This also helps complete the moisture seal.
