What’s the Polyurethane blade

Polyurethane blade

A polyurethane (PU) squeegee blade is a popular choice in the printing industry for its durability and flexibility. It is frequently used to push ink through screens onto substrates like textiles, paper, or plastic.

The unique properties of PU make it an excellent material for squeegees because it has a high resistance to abrasion and chemicals, making it ideal for long-lasting use.

Moreover, PU blades are available in different hardness levels ranging from soft to hard. The softer blades are better suited for printing on delicate fabrics as they conform better to the surface.

On the other hand, harder blades are ideal for printing on flat surfaces as they provide greater control and pressure on the print area.

It’s crucial to select the right PU squeegee blade based on your specific printing needs. Quality brands offer various sizes and shapes with different degrees of durometer that can cater to all sorts of printing applications.

A good quality PU squeegee blade can significantly enhance print quality while minimizing wear and tear on the screen-printing equipment over time.

Benefits of PU Blades

PU squeegee blades are becoming increasingly popular in the printing industry due to their numerous benefits.

One of the main advantages of using PU blades is their durability. Unlike traditional rubber blades, PU blades are resistant to wear and tear caused by ink and solvents, making them a cost-effective option for high-volume printing.

Another benefit of PU squeegee blades is their versatility. They can be used with a wide range of inks, including UV-curable and solvent-based inks, which makes them ideal for various printing applications.

PU squeegee blades also offer superior precision when compared to traditional rubber blades. This precision helps to ensure consistent results throughout the entire printing process, resulting in high-quality prints that meet or exceed customer expectations.

In summary, choosing a PU blade over a traditional rubber blade can save money on replacement costs while providing better performance and more consistent results.

Suitable Surfaces

When it comes to using a PU squeegee blade, choosing the right surface is crucial. The blade works best on smooth and flat surfaces such as glass, metal or polished stone.

Uneven or textured surfaces can cause the blade to skip or leave streaks behind. It’s important to ensure that the surface is clean and free from debris before using a squeegee blade.

In addition to the type of surface, consider the temperature and humidity levels in the environment. High temperatures can cause the blade to soften, while low temperatures can make it brittle and more prone to chipping or cracking.

Similarly, high humidity levels can cause moisture buildup on the surface, making it difficult for the blade to glide smoothly.

Overall, using a PU squeegee blade on suitable surfaces with ideal environmental conditions will result in a streak-free finish that looks professional and polished. Be sure to take into account all these factors when selecting your next project!

Tips for Use

When it comes to maintaining a clean and streak-free surface, a PU squeegee blade can be an essential tool in your cleaning kit. To make the most of this versatile tool, here are some tips for use.

Firstly, ensure that your squeegee blade is free from damage or imperfections before use. This will prevent any scratching or damage to the surface you are cleaning.

Secondly, choose the appropriate size of squeegee blade for the task at hand. A smaller size may be suitable for cleaning windows while larger sizes may be more effective on floors or walls.

When using your PU squeegee blade, maintain an even pressure across its width as you move it across the surface being cleaned.

Use long and overlapping strokes for best results. Finally, rinse the squeegee blade frequently with clean water to remove any debris or dirt buildup during use.

With these simple tips, you can make the most of your PU squeegee blade and achieve a spotless finish on various surfaces around your home or workplace.

When it comes to maintenance, the PU squeegee blade is an important component in printing equipment that needs regular care.

The first step in maintaining a PU squeegee blade is keeping it clean. Residual ink can accumulate on the blade, causing it to become brittle and break down over time. Use a rag or sponge to remove any leftover ink from the blade after each use.

In addition to cleaning, proper storage of your PU squeegee blade is also crucial for its longevity. Avoid storing it in direct sunlight or extreme temperatures as this could cause it to warp or crack. Instead, keep the blade stored in a cool and dry place until its next use.

Lastly, replacing your PU squeegee blade on schedule will ensure good print quality and prevent damage to other components of your printing equipment.

Be sure to check with your manufacturer’s guidelines for when replacement is recommended based on usage frequency and intensity.

By following these simple maintenance tips, you can extend the life of your PU squeegee blades and keep them working at their best for years to come!


In conclusion, the PU squeegee blade is an essential tool in any print shop. Its unique properties make it a superior choice over other materials like rubber or vinyl.

PU blades have excellent resistance to chemicals, abrasion, and wear – making them last longer than other options.

Moreover, the flexibility of PU squeegee blades allows for better ink transfer and smoother printing processes.

This gives printers more control over their work, leading to higher quality prints and satisfied customers. Additionally, the flexibility of a PU blade reduces the risk of damage to screens or substrates during printing.

In summary, investing in high-quality PU squeegee blades can significantly improve your printing process’s efficiency and outcome while reducing costs associated with frequent replacement of inferior products.

With its numerous benefits regarding wear resistance, chemical resistance, and ink transferability – this option is undoubtedly worth considering for anyone in the printing business looking to enhance their workmanship.
