Endurance test for stringent demands
DENSORB® absorbent mats can be used in many applications. They often have to endure a lot - for example, if they are a high-absorbent surface near the machine. To ensure our products always perform at their full potential in your company, we subject them to detailed load and quality tests in our in-house test laboratory.
A quality check is always necessary when a product is being developed - but also for long-term quality monitoring. We use official standards from the American Society for Testing and Materials (ASTM). Whether the product meets our requirements is checked in detail and in several test runs using comparative measurements
Depending on the design, DENSORB® absorbent mats should withstand strong and permanent loads. A high tear resistance is especially important if the application involves strong mechanical loads.
We demonstrate this with a tensile strength test. Test pieces are prepared in the form of cut strips (150 x 25 mm). These are clamped in a force-displacement measuring device and stretched at a constant speed. Does the material withstand the required load? Only if the answer is "yes" will the next test step be tackled.
Weight (ASTM 3776) and Thickness (ASTM 5736)
The low weight of our DENSORB® absorbent mats is an important quality factor as it contributes significantly to lower disposal costs. It also ensures that handling and storage is much easier for the user. Therefore, in our tests, we examine the basic properties of the material, weight and thickness. Test pieces with a diameter of 113 mm are prepared, measured and weighed for this purpose. If the test pieces meet the requirements, we'll give them the green light.
Absorption (ASTM 726)
One of the most important tests is of course absorption capacity. DENSORB® absorbent mats absorb oil up to 16 times their own weight visibly faster than conventional absorbents, ensuring optimum results when cleaning up leaks. Absorbency is therefore demonstrated in our testing laboratory. The test piece is immersed in oil for 30 seconds. It is weighed before and after to determine the absorption quantity which is the weight difference. If the required performance is proven - the test is passed.
Only products that can withstand all the requirements of our quality criteria will make it into our DENSORB® range.

Mobile absorbent emergency kits: Tackle hazardous substance leaks quickly wherever they occur.
DENSORB® offers speed and flexibility when responding to emergency spills. These emergency response kits are designed to quickly and safely mop up and contain spills. They can be taken directly to the spill site and used at individual workstations, around machinery or service vehicles.
The 7 biggest mistakes when emptying spill pallets
It is not uncommon for liquids to leak and this can happen at any time. But what then? How does the liquid get out of the tray? This is not as trivial as it sounds: when emptying drip pans, serious mistakes can happen. Here you can find out what you should never do under any circumstances - and how to do it correctly.
Responding correctly in an emergency - Our Academy instructor shows how to
Tobias Authmann has a degree in biology and has been working for the DENIOS Academy for many years as a specialist for hazardous substance storage and occupational safety. In his practical training course "Leakage Emergency Training", he imparts the necessary know-how for avoiding and combating hazardous substance leaks. We talked to him about his experiences.
DENSORB® nonwovens are used in many areas of application. They often have to withstand a lot - for example, when they are permanently used as a highly absorbent underlay near the machine. Read here which load and quality tests are carried out in our in-house test laboratory.
Time and again we hear about oil spills on the water. In the general public, it is mainly the very large catastrophes that gain sad notoriety, but even on a supposedly small scale, oil spills can have catastrophic effects if they get into local waters. But how can companies take precautions? We answer the most important questions.
