Mylar-teippi Lenovo 5M21H89569 — eristävä teippi elektronisille komponenteille, malli 5M21H89569

Mylar tape Lenovo 5M21H89569 is a thin polyester (Mylar) insulating and adhesive tape designed for use in electronic assemblies and computer components. The tape provides reliable electrical insulation, heat resistance and surface protection for cables, connectors and printed circuit boards. It is suitable for repair, manufacturing and shielding tasks where a stable, non-conductive tape is required and compatible with typical laptop and desktop internal assemblies.

Advantages

The Mylar polyester construction offers dimensional stability and low stretch, maintaining insulation properties over time. A pressure-sensitive adhesive backing ensures secure adhesion to plastics, metals and silicone-coated surfaces commonly found in electronic devices. Heat-resistant characteristics allow the tape to withstand elevated temperatures during soldering or operation without degrading, while the smooth non-conductive surface protects component surfaces from abrasion and short circuits.

Suitable for

• Insulating and protecting cable runs inside laptops and PCs
• Masking and protecting components during soldering or rework
• Securing and insulating connectors and flex cables
• Shielding sensitive areas on circuit boards from abrasion or accidental contact

Key specifications

• Material: polyester (Mylar)
• Function: electrical insulation and surface protection
• Adhesive type: pressure-sensitive adhesive suitable for electronics
• Thermal behavior: heat resistant for typical electronics soldering and operating temperatures
• Physical form: thin flexible tape suitable for conforming to curved surfaces

How to use

Ensure surfaces are clean, dry and free of oils or dust before application. Cut the required length of Mylar tape and apply with gentle pressure to create full contact with the substrate; press down along the tape to activate the adhesive and avoid trapped air. For overlapping layers, apply successive strips with slight overlap to maintain continuous insulation. When used during soldering, leave sufficient clearance between the heat source and adhesive edge to prevent swelling or discoloration.

Recommendations

Store the tape in a cool, dry place away from direct sunlight. For critical high-temperature or precision RF shielding applications, verify compatibility with the device materials and operating environment before large-scale use.
