In silent hydraulic breakers, polyurethane (PU) components are not just about damping and noise reduction—they play a direct role in equipment lifespan, operational stability, and maintenance costs. Choosing a supplier solely based on price is risky. Instead, the value lies in the material performance behind the numbers.
You can find more information on our web, so please take a look.
Before making a purchasing decision, make sure to ask your PU supplier these 5 essential questions. They’ll help you identify whether you’re working with a true material solution partner—or just a parts vendor.
If a supplier says, “We’ll make whatever hardness you want,” that’s a red flag. It usually means they don’t understand either the material characteristics or your equipment’s requirements—and therefore can’t provide real engineering value.
Different parts of a breaker experience different loads and stresses. Choosing the correct Shore A hardness (typically between 80A and 98A) requires a clear understanding of your working environment—impact force, vibration frequency, temperature, and mounting constraints.
Wrong hardness leads to:
Poor damping effect
Cracking or deformation under load
Unstable operation
Frequent replacements and high maintenance costs
High-end hydraulic breakers typically require non-standard, custom-shaped parts. Custom PU parts are critical for:
Perfect assembly fit
Optimal vibration absorption
Longer service life under extreme working conditions
If a supplier only offers standard parts or cannot meet tight tolerance drawings, it’s a sign of limited technical capability.
Bottom Line: Custom parts = higher reliability + better performance
There are multiple PU systems (polyether, polyester, polycarbonate) and processing methods (CPU, TPU, spraying), and each has distinct performance profiles.
CPU offers superior tear strength, abrasion resistance, and fatigue life, ideal for high-frequency impact applications.
TPU may be suitable for light-duty parts.
Ask clearly about the system and process to avoid mismatches that may result in short service life or functional failure.
A trustworthy PU supplier should have a complete QC system, including:
Raw material inspection
Final product testing
Full traceability and factory inspection records
Tip: Ask for testing reports and client references—especially from major OEMs. If a supplier has passed audits by top-tier manufacturers, they are unlikely to deliver substandard parts.
PU performance can degrade under unexpected changes in load, environment, or frequency. A good supplier will:
Offer installation guidance
Analyze wear issues

What you need is not just a “supplier,” but a material solution partner who supports your entire operation lifecycle.
A polyurethane component may seem small, but it plays a massive role in hydraulic breaker performance. By asking these 5 questions, you’re not just managing cost—you’re investing in efficiency, safety, and long-term uptime.
Shore hardness and size aren’t the only factors when specifying sheets of material for construction, engineering or manufacturing. Quality polyurethane sheets have emerged as indispensable problem solvers in various industries.
High-density, resilient materials are needed for a multitude of purposes. This can include use as structural barriers and insulators, or to be machined down to size to create blades, pads, sleeves, slats, flaps, scrappers and liners, for example.
Polyurethane stands out as the material of choice for an increasing array of applications due to its remarkable versatility and performance. Why is that, and what do we mean by ‘quality’ polyurethane?
In this comprehensive buyer’s guide, we delve into why quality polyurethane is paramount and what defines its excellence. Additionally, we’ll explore two other crucial applications: polyurethane wheels and rollers. These components play pivotal roles in numerous industries, offering durability, traction, and smooth operation.
As polyurethane is now a popular, inexpensive and versatile option for creating parts, there are suppliers who offer cut-price sheet versions. The problem that raises is that moulding standards can vary considerably, and you can end up with a cheap polyurethane with intrinsic defects.
The sort of issues you face include contaminates or incorrect additives and catalysts in the mix, reducing PU’s effectiveness and durability. There could also have been a polyurethane moulding process that allowed air or moisture bubbles in the mix. This can also strip away some of the main benefits of using polyurethane, including its incredible durability.
It pays to find a quality version, from experts in this sector, flawlessly mixed, moulded and finished. The best sign of quality polyurethane is its stellar performance.

Each spec for polyurethane sheet stock is different. That’s even true if you are keeping them whole to use as structural features. You need to source the ideal thickness and density when ordering quality polyurethane sheets and ensure accuracy in the level of malleability.
One of the biggest considerations in construction, refurbishment and retrofit projects, is sheets that meet thermal and acoustic insulation requirements. However, polyurethane sheets may also need to carry out a number of other key tasks, such as forming a tough, durable protective layer around sensitive areas of the structure or its contents, or for shock and vibration management purposes within a building.

Quality polyurethane sheets are also increasingly used to create smaller parts that carry out demanding tasks. For instance, to engineer components that work brilliantly, while also managing moisture incursion, contamination spread or damage from acidic substances. This could be an engineered part such as a spacer, gasket or flexible liner for example.
You may even need to source polyurethane sheet according to colour, as well as dimensions and tensile properties, such as for chopping boards or other household projects.
One of the many advantages of quality polyurethane sheets is that they can be machined with confidence, and without leaving a ragged, flaky, scratched or warped cutting edge.
What about other detailing and special finishes required for quality polyurethane sheets?
In the hands of experts in polyurethane moulding, you get sheets that are 100% accurate and consistent across entire production runs. These sheets will then be incredibly resilient, which means you can’t reform or reheat them. However, they can be coated to your exact requirements, ready for problem-free machining.

Another reason to opt for quality polyurethane sheet is that they can outperform alternative materials, including rubber and plastic.
For example, unlike rubber, polyurethane is resistant to contaminates and can withstand a great deal of wear, tear and time, without ripping or warping in the face of friction or extreme temperatures. The way
PU sheets are made and also ensure they produce a material with excellent pressure and load-bearing values. This is another way in which they can be more resilient than rubber and plastic sheets.
Polyurethane sheets can be produced to have equal strength to metal ones, but they will be lightweight, versatile and far less expensive. They will also be far more resistant to abrasion and corrosion, adding to their superiority over metal sheets used for various purposes.
The thermal and acoustic management capabilities of quality polyurethane also set it apart from sheets made from other materials. When noise reduction matters, there really is no contest between PU and metal.
Sourcing quality polyurethane sheets from a British manufacturer also means you get a fast turnaround, as well as a sheet stock material that can match even the most exacting of standards
