Oyaide NRF-005L (Non-magnetic noise suppression sheet)

Our Business Hours is Mon to Fri / 11:00 to 18:00 JPN time
We will close Sat and Sun, so we will reply to inquiry that received weekend on next week.
Your understanding will be appreciated.

We are receiving the customer order with first comes first serves basis both on website and at real shop.
So occasionally it will be sold out while having email communication.
Please understand in advance.

Japanese consumption tax is not required for international shopping. However you may be required to pay duty, tax and import fee when receiving your items in your country. You must pay all these duty, tax and fee as receiver/importer and we do not cover any of them.

★Non-magnetic, anti-wrinkle sheet made with high-performance nonwoven fabric PULSHUT

Following on from the tape type "NRF-005T", we now have the "A4 sheet type" which has been highly requested.

The NRF-005T is suitable for wrapping electrical wires and attaching ICs and electronic components, while the NRF-005L is suitable for attaching to large areas such as the inside and outside of housings and around the circuit boards of audio equipment.

Once again, our focus is on not letting the fish out of the clear water. Audio accessories that claim to have noise-absorbing properties can, unless carefully designed, filter out the nuances and realism that should be present in music and video, causing them to lose their vitality.

The NRF series resolves the dilemma between noise reduction and fidelity to the original sound, offering groundbreaking and innovative products for all audiophiles.

■Five features of Parshut R ◎High-performance nonwoven fabric that does not use any magnetic materials.
◎Effective against noise over a wide frequency range from the MHz to GHz bands.
◎The base material is thin at 0.05mm and extremely lightweight.
◎Excellent flexibility, allowing it to be attached to uneven surfaces.
◎Both the sheet surface and the cut surface have high insulating properties, so it can be attached to conductive surfaces.

■What is "PULSHUT"?
Conventional noise suppression materials have the property that the amount of noise suppression can be controlled by adjusting the magnetic material and amount used. They have high magnetic loss characteristics and achieve noise absorption by converting electromagnetic noise into heat. However, this increases impedance in certain frequency bands, which also affects the waveform of the original sound. This is similar to the property of ferrite cores. In the audio industry, it is well known that magnetic materials cause electromagnetic fields to be generated, which changes sound quality, and noise suppression and fidelity to the original sound have been mutually exclusive. This means that, just like EMC/EMI countermeasures, appropriate noise countermeasures are also needed in audio.

By applying a special surface treatment to high-performance nonwoven fabric, PULSHUT R has high noise suppression performance despite being non-magnetic. This characteristic makes it possible to suppress only the noise component while minimizing the impact on the waveform of the original sound.

■Features of NRF-005L
The NRF-005L is A4 size (297 x 210 mm) and features a versatile sheet shape. The Pulshut R is very thin at 0.05 mm thick and highly flexible, so it can be cut to any size you like. Of course, you can also stick an A4 sheet directly onto it without any problems.

The NRF-005L is packaged in a custom-made file. Please use this to store any remaining NRF-005L.

Recommended use for NRF-005L: Inside and outside the housing of audio equipment (recommended when the frame ground is connected to the circuit)
・Around the circuit board and pattern surfaces of audio equipment ・Around the motherboard and pattern surfaces of PC audio ・Around the body earth of in-car audio

■Complies with the RoHS Directive and reduces environmental impact.The content of environmentally hazardous substances (lead, mercury, hexavalent chromium, cadmium, etc.) is kept below the measurable limit, complying with the RoHS Directive.

■Excellent noise absorption with simple use. It's incredibly simple to use. Simply attach it to the input/output terminals of audio equipment, around noise-prone areas, or on cables and plugs to achieve superior noise suppression. It lowers the noise floor without distorting or modifying the original sound waveform, improving delicate expression with minimal extraneous noise. It also reduces blurring of video contours and enhances color clarity. In terms of sound quality, it improves the signal-to-noise ratio, stabilizes the center of gravity, focuses the sound image, eliminates noise that fills air gaps, and creates a sense of expanded sound field. In terms of video, it contributes to improved tonal expression and color reproduction.

■ Flexible, easy to cut and apply. To properly cut the sheet type, use sharp scissors or a cutter. Its excellent flexibility allows it to be applied to curved surfaces such as cables, making it easy to process and work with. The acrylic adhesive provides reworkable adhesion while retaining sufficient holding power, allowing it to be reapplied multiple times. The protective layer uses PET resin, which keeps the shape stable even after cutting, allowing the nonwoven fabric to be applied without fraying. The key to a neat finish is to apply it with light tension.

■Precautions for use
1. It can be used in a wide temperature range of -20 to 90°C, but please avoid attaching it to parts (CPU, GPU, vacuum tubes, etc.) that are expected to overheat or cool beyond this temperature.
2. Avoid using the product in a way that hinders heat dissipation, such as blocking the heat dissipation holes of an amplifier or computer.
3. Avoid storing in direct sunlight.
4. Avoid storing or using the product in hot and humid conditions, as this may cause the adhesive to deteriorate.
5. Be sure to thoroughly wipe off any dirt or oil from the adherend (opposite surface) before proceeding with the application.
6. The adhesive is reworkable, but repeated application and removal will weaken the adhesive.
7. The tape is designed to not leave any adhesive residue, but just to be safe, please do not stick it in places where leaving marks would be a problem.
8. After application, you can remove it by hand, but just to be on the safe side, please avoid applying it to places where it will be difficult to remove.
9. When marking, please use an oil-based pen or ballpoint pen on the surface of NRF-005L, as the separator (release paper side) is ink-repellent.
