Semi-conductive Tape
What is Semi-Conductive Tape
Semi-conductive tape is a semi conductive ethylene propylene rubber tape based insulating tape with good conformability. No need for vulcanization, stable performance, wide temperature range, stable conductivity, and good compatibility with cable shielding materials. It is a new type of material with high elasticity, wear resistance and electrical conductivity, and is widely used in electronic and electrical fields. This material can withstand high temperature, low temperature, strong acid, strong alkali and other harsh environment, so it has been widely used in various electrical equipment, electronic products, communication equipment, semiconductor fields.
Advantages of Semi-Conductive Tape
No residue, no mess
Crucially, unlike tapes with adhesive, semi-conductive tape leaves no sticky residue. This quality not only ensures a clean application but also allows for easy removal and reapplication if needed.
Versatility in applications
The self-amalgamating nature of the tape makes it suitable for various tasks. Whether it's wrapping around electrical connections, sealing plumbing joints, or providing a protective layer for automotive wiring, the tape's working mechanism remains consistent.
Bonding strength
Semi-conductive tape provide excellent bonding strength, enabling them to hold materials together securely. Depending on the type of tape and its intended purpose, adhesive tapes can offer varying levels of adhesion. Some tapes are designed for permanent bonding, ensuring a long-lasting hold, while others allow for easy removal and repositioning.
Surface compatibility
Another insulationadvantage of semi-conductive tape is their ability to adhere to various surfaces. Whether you are working with paper, plastic, metal, glass, fabric, or even uneven surfaces, there is an adhesive tape suitable for the task. Insulation tapes are engineered to provide optimal adhesion on different materials, making them a versatile choice for numerous applications.

How to Choose the Quality of the Semi-Conductive Tape
In fact, there are two standards for the quality of the adhesive tape in use, one is initial adhesion, and the other is retention. The two are inversely proportional. In general, adhesive tapes with a viscosity less than 10 are less coated with glue, generally only about 20 microns, such as stationery tapes, ordinary promotional binding tape. The initial adhesion of normal sealing tape is between 15-20, and the thickness of this tape is generally 22-28 microns. It is the standard thickness. However, most of the tapes on the market are doped with impurities, so the thickness is increased. To mask the impurities, the glue is also doped with color powder, so the transparent tape appears egg yellow and light green. Such tapes are generally inferior.
For colored tape, yellow and khaki are more common. Tighten the sticky and then quickly pull it apart. You can pull off the glue on one side and you can see the purity and transparency of the original film. You can also look at the thickness of the glue. If no glue is pulled apart or pulled apart in a point, there is a lot of impurities in this glue, and the glue has no cohesion. The second is that there is too much water and it has evaporated. At this time, the initial adhesion of this tape has dropped very much, and the hand can be distinguished. In fact, there are many ways to distinguish the quality of the tape. As long as you pay more attention to your life, you can tell the quality of the tape.
The application range of semi conductive rubber tape is very wide, and the following are some common use scenarios:
Electronic products: Semi conductive rubber tape is widely used in the production process of mobile phones, TVS, computers and other electronic products. Because it can effectively isolate and shield electromagnetic interference, it can reduce the failure rate and damage rate of the product.
Communication equipment: In various communication fields such as wireless network equipment and satellite communication equipment, semi conductive rubber tape is also widely used, which can effectively reduce noise and electromagnetic interference and improve communication quality and speed.
Power equipment: In the field of power equipment, semi conductive rubber tape have also been widely used. It can help power equipment effectively isolate and shield electromagnetic interference, improve the reliability and stability of power equipment.
In the process of using electricity, although people have noticed that the size of the cross-sectional area of the power cord has an impact on the safe use of electricity, they often fail to pay attention to the use of insulating tape on the joints. The laying of power lines is becoming more and more messy, running under the wooden floor, in the wall, in the partition, and wet underground or in the water. If the insulating tape is used improperly, electric leakage will occur, endangering personal safety. Therefore, we must use the insulating tape correctly. The power cord connectors are divided into “+” word connection, “-” word connection, and “T” word connection. The joint should be tightly wound, lubricated and free of burrs. Otherwise, before disconnecting the thread, use wire cutters to press it lightly, then wind to the pressure port, and then swing left and right, the thread will be compliantly disconnected at the joint. If the joint is in a dry place, first wrap 2 layers of insulating black tape, then 2 layers of plastic tape, and then use insulating self-adhesive tape to stretch about 200%, wrap 2 to 3 layers, and finally wrap 2 layers of plastic tape.
Although the Semi-Conductive Tape has outstanding insulation voltage resistance, flame retardant, weather resistance and other characteristics, it is suitable for wire connection, electrical insulation protection and other characteristics, but if the operation is improper, it will not only not have the protective effect, but may also endanger the human body. Safety may cause a fire. Therefore, when using it, it is necessary to have basic common sense in this area.
How to Determine the Strength of an Semi-Conductive Tape
An semi-conductive tape is a strong and durable tape that is commonly seen in use in a variety of industries.
In the application of an semi-conductive tape, the backing comprises an elastomeric or polymerized elastic polyurethane film. This backing is typically a nylon-mesh-like substance, although other types of materials may be used. The tape can also have an adhesive side featuring conductive thread work that runs along the entire length of the backing. There are two types of adhesives used in this type of tape: Mechanical or electrical. Mechanical adhesives use physical forces to apply the adhesive. Electrical adhesives use electrical energy to apply the adhesive, thereby allowing it to be more powerful.
The amount of adhesive will determine the thickness of the vinyl material that the tape will be applied to. Adhesive tapes are usually applied with a trowel and will provide a smooth, flat surface for the adhesive to adhere to. The thickness of the adhesive material that is used in the application of the tape will vary, depending on the application.
When measuring the thickness of the tape, one must consider the total weight of the carrier. The measuring device used to measure the adhesive's strength is referred to as a torsion spring. This type of torsion spring is commonly found on packaging tapes that have been printed with adhesives and other materials.
The other consideration when measuring the strength of an adhesive tape is the type of fabric to be measured. Some tapes are manufactured from a combination of different materials. These materials may include; polyurethane foam, polyurethane, polyester, nylon, cotton, and weft fibers. Most manufacturers specify the thickness of the electrically conductive stretchable fabric on the packaging tape's packaging slip. The thicker the material of the tape, the stronger the tape will be.
Moisture, often absorbed into the tape from humid air, breaks down the long-chain polyester molecules that are the major structural ingredient of the recording and back-coat layers. The reaction, called binder hydrolysis, produces a residue of low-molecular weight oligomers and carbolic acid. This residue has adhesive properties that interfere with tape usage. The hydrolysis reaction can also weaken the tape structure.
The amount of moisture a tape is exposed to determines the speed and degree of hydrolytic decay. Long-term exposure to high relative humidity conditions will tend to increase the amount of “adhesive” oligomer residue. Extended exposure to low rh can stabilize or even reduce the amount of residue.
Humidity has three additional effects on magnetic tape. It can impact the physical dimension of tape, it can allow for damaging fungal growth and it can compromise a tape’s elasticity.
Tape expands and contracts with moisture content. Even though tape can be thousands of feet long and only a very small fraction of an inch thick, the primary vector of expansion is thickness. As tape absorbs moisture, the tape gets thicker and tightens the pack. This can cause stretching. As tape releases moisture in low rh environments, it gets thinner and loosens the pack. This can result in tape slippage, folding and cinching.
If relative humidity is high enough for an extended time, fungus can grow on and damage tape. For this reason, tape should never be stored in an environment that exceeds 50% rh.
Should tape actually be submerged, even for short periods of time, the elasticity and structural integrity can be compromised. Extreme care must be taken handling wet tapes as physical stress put on tape when the elasticity is compromised can cause permanent deformation.
How to Make Your Semi-Conductive Tape Stick Better
Clean the surface
Make sure that the surface is clean and dry before applying tape. If there is any dirt or grease on the surface, it will prevent the tape from sticking properly. To clean your surface, start by washing it with rubbing alcohol. Make sure to dry it thoroughly afterwards with a soft cloth.
Keep in mind that some surfaces just make it difficult for tape to stick, no matter how much you’ve cleaned them. Rough surfaces of any kind don’t make good contact with the tape and require the use of a product with stronger, thicker adhesive.
Mind the temperature
General purpose tape won’t stick properly at low temperatures. It will become brittle and dry, and peel within days. This is because the adhesive freezes in the cold, gradually turning into a tack-free solid. If you are dealing with cold surfaces, you’ll need to warm them up somehow (you can apply heat with a hairdryer) or use a tape that’s specifically designed for low temperatures.
Apply it properly
If you want your tape to stick better, you need to apply it correctly. Adhesive tape uses what’s called pressure sensitive adhesive. This means an even pressure needs to be applied over its full width in order for a secure bond to form. Use a smooth, even motion to apply the tape. After the application, you can use a roller or your fingers to press it down. This will make sure there are no air bubbles under the tape.
