B0201ML - Ultra-thin amber polyimide tape high temperature

An ultra-thin polyimide tape for precision technical applications

TheB0201MLis a single-sided adhesive tape made of amber polyimide with high-temperature silicone adhesive, designed for applications where the thinness of the material is a key criterion. With a total thickness of only35 µm, it ensures reliable electrical insulation and precise technical masking while minimising the thickness in the assembly.

It is particularly suitable for electronic, electrotechnical, and industrial environments where space is limited, or when a highly conformable tape is required to closely follow the geometry of components or areas to be protected.

A thinner version of the B0201M

TheB0201MLbelongs to the same product family as theB0201M, which it shares the technical logic: amber polyimide backing, high-temperature silicone adhesive, good electrical insulation, and excellent thermal stability. The main difference between the two references lies in the thickness.

TheB0201MLis theultra-thin version, ideal when priority is given to low thickness, flexibility, and conformability.

TheB0201M, thicker, will be more suitable when looking for a bit more mechanical presence, robustness in handling, or a more 'visible' hold in the application.

This complementarity allows for a more precise choice of the right reference according to the constraints of your application:

• B0201MLfor maximum finesse
• B0201Mfor a more robust compromise

A high-performance solution for high-temperature insulation and masking

TheB0201MLis particularly suited for masking operations in electronics, wave soldering, and the insulation of coils, transformers, motors, and capacitors. Its high thermal stability allows it to withstand harsh process environments, while its dielectric strength of6 kVmakes it a reliable solution for fine electrical applications.

Despite its low gauge, it maintains good resistance to abrasion, tearing, puncturing, and solvents, which enhances its relevance in demanding industrial uses.

An ultra-thin construction for low thickness

The main advantage of theB0201MLis its total thickness of0.035 mm, very low for a high-temperature technical tape. This finesse makes it particularly relevant for applications where every micron counts.

This allows for:

• a very low thickness
• better integration into compact assemblies
• more discreet masking
• a more precise application on small areas

A thin version in the B0201 family

TheB0201MLshould be understood as the thinnest version of the silicone polyimide familyB0201. For users needing a slightly thicker, more robust or easier to handle solution, there is also theB0201M.

This allows for:

• choosing the version suited to the actual need
• directing towards the B0201ML for thinness
• directing towards the B0201M for more robustness
• covering similar applications with two thickness levels

A high-temperature polyimide support

The polyimide support of theB0201MLis designed to withstand very high temperatures while maintaining good dimensional stability.

This allows for:

• excellent heat resistance
• good resistance to extreme cold
• reliable stability in process
• adaptation to severe thermal environments

A silicone adhesive stable in hot environments

The silicone adhesive mass of theB0201MLremains effective in high-temperature processes. It is particularly suited for technical applications requiring good tape performance despite the heat.

This allows for:

• good performance up to 240°C continuously
• performance up to 268°C in the short term
• better bonding stability
• compatibility with industrial thermal processes

Good electrical insulation

With a dielectric strength of6 kV, theB0201MLeffectively meets the electrical insulation needs in fine applications.

This allows for:

• isolating compact components
• securing sensitive areas
• using a very thin substrate without compromising safety
• improving the reliability of technical assemblies

Good chemical and mechanical resistance

TheB0201MLoffers excellent resistance to solvents and chemical agents, as well as good resistance to abrasion, tearing, and perforation.

This allows for:

• better performance in industrial environments
• greater durability of the tape
• better handling resistance
• good stability in demanding processes

An ideal solution when thinness is a priority

TheB0201MLis particularly interesting when the application requires high-performance insulation or masking with minimal thickness.

It allows for:

• reducing bulk in assembly
• improving placement accuracy
• better integration into compact systems
• achieving very fine technical insulation

Excellent temperature resistance

TheB0201MLmaintains its performance in very severe thermal environments, making it a particularly reliable tape in hot industrial processes.

It allows for:

• continuous use up to 240°C
• point resistance up to 268°C
• better stability in thermal processes
• good safety for technical operations

Good insulation for fine electrical applications

Its dielectric strength and low thickness make it a very relevant solution for electrical applications where compactness of the assembly is important.

It allows for:

• the insulation of fine components
• the protection of compact electrical areas
• reliable safety in technical systems
• adaptation to electronic environments

A finer alternative to the B0201M

TheB0201MLperfectly complements theB0201Min the range. Where theB0201Mprovides more mechanical presence, theB0201MLmeets the needs for extreme fineness and high conformability.

It allows for:

• choosing the right thickness according to the use
• using the B0201ML for fine areas
• using the B0201M for more robust uses
• having a consistent range according to technical needs

Productivity and performance

• ultra-fine and conformable
• excellent high-temperature resistance
• good electrical insulation
• good chemical and mechanical resistance
• also available in a thicker version: B0201M

Masking in electronics

TheB0201MLis very suitable for masking operations in electronics, especially when a high level of precision and excellent thermal stability are required.

It allows for:

• locally protecting sensitive areas
• creating fine masks
• working on compact components
• improving the precision of operations

Insulation of coils, transformers and capacitors

Thanks to its good electrical insulation and high thermal stability, theB0201MLcan be used for the insulation of various electrotechnical components.

It allows for:

• the insulation of coils
• the protection of transformers
• the insulation of motors
• the protection of capacitors

Wave soldering and thermal processes

TheB0201MLis suitable for wave soldering processes and other industrial applications exposed to heat, especially when the tape needs to remain very thin.

It allows for:

• protecting certain areas during soldering
• withstanding high thermal cycles
• ensuring precise technical masking
• using a thin tape in a hot environment

Powder coating and high-temperature protection

Like the other silicone polyimides in the range, theB0201MLcan be used in certain masking applications before powder coating or heat treatment.

It allows for:

• masking specific areas
• maintaining precise contours
• withstanding process heat
• improving finish quality
