PVC magnetic tape is an indispensable tool for organization and marking in warehouses and offices. Allows quick identification of goods and storage locations.
You can use dry-erase markers (for multiple description changes) or permanent ones (for durable markings). In the case of dry-erase markers, the inscription can be wiped off with a sponge and written anew.
Magnetic tape is flexible and soft, so it can be easily cut with ordinary office scissors. This gives full freedom in creating a warehouse marking system.
Unlike stickers, you don't have to scrape off glue residue when changing label location. Ideal for warehouses where goods location often changes (rotation).
We sell tape in 10m rolls, which is enough for many labels. Long rolls are economical for large logistics companies.

Strengths as well as weaknesses of neodymium magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:
  • They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
  • Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external magnetic fields,
  • The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • They are known for high magnetic induction at the operating surface, making them more effective,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Due to the possibility of flexible forming and adaptation to individualized requirements, NdFeB magnets can be manufactured in a variety of geometric configurations, which amplifies use scope,
  • Wide application in electronics industry – they are commonly used in computer drives, motor assemblies, precision medical tools, as well as complex engineering applications.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of NdFeB magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complicated shapes in magnets, we recommend using a housing - magnetic mount.
  • Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these magnets can complicate diagnosis medical in case of swallowing.
  • Due to complex production process, their price is relatively high,

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

Information about lifting capacity was determined for ideal contact conditions, assuming:
  • on a block made of mild steel, optimally conducting the magnetic flux
  • whose transverse dimension is min. 10 mm
  • characterized by even structure
  • without any insulating layer between the magnet and steel
  • under perpendicular force direction (90-degree angle)
  • in temp. approx. 20°C

Key elements affecting lifting force

In real-world applications, the actual lifting capacity results from a number of factors, presented from crucial:
  • Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
  • Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets
Powerful field

Handle with care. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.

Maximum temperature

Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Safe distance

Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).

Magnet fragility

Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Pinching danger

Big blocks can smash fingers instantly. Do not place your hand betwixt two strong magnets.

Magnetic interference

An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Maintain magnets close to a device to prevent damaging the sensors.

Danger to pacemakers

Patients with a pacemaker should keep an absolute distance from magnets. The magnetism can disrupt the operation of the implant.

Allergic reactions

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

Product not for children

Strictly keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.

Combustion hazard

Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
