DENSORB Guide: Rapid & Safe Containment of Leaks & Spills

In a busy production environments, accidents are going to happen. Leaks, drips and spills are something that needs to be prepared for - especially when dealing with hazardous substances. Any facility that uses, processes or stores hazardous substances should have an emergency plan in place for the effective containment and absorption of these materials. From minor machinery drips to large-scale spills, any escaped toxic chemicals pose a risk to staff, the environment and the very future of a company.

Our extensive range of market-leading DENSORB absorbents offer high-quality and reliability when you need it most. DENSORB absorbents are available for every conceivable application, so whether you're working with acids, alkalis, oils - and even unknown fluids - DENIOS has got you covered. 

Why should I use absorbents?

  • Absorbents protect employees, customers and the environment 

    Even in the case of minor leaks and machinery drips, the environment and your employees are at risk. Coming into contact with hazardous substances can be incredibly dangerous for your staff, and spills can also lead to slips and trips. High-performance DENSORB absorbents rapidly absorb spilled liquids, helping you to avoid incalculable risks and any associated costs - in all industrial and chemical areas.

  • Absorbents save money 

    Contamination of soil, sewage and ground water can cost a company a lot of money. Using DENSORB absorbents helps to avoid high clean-up and disposal costs.

  • Absorbents comply with legal regulations and environmental standards 

    Regulations and environmental standards such as ISO 14001 require responsible handling of hazardous liquids. It's your legal responsibility to source suitable absorbents and have them available onsite in the event of a spill. 

How do I use absorbents effectively?

The application possibilities of DENSORB absorbents are as diverse as the problems you can solve with them; whether as a preventive soil cover, underlay during filling, cleaning and maintenance work or for the rapid absorption of leaking liquids.

What are the benefits of DENSORB absorbents?

  • Capacity & Performance
    DENSORB absorbents have an exceptional absorption capacity of up to 16 times their own weight. Due to this ultra-high absorption capacity, consumption is minimised and the spilled liquid is absorbed at a rapid rate. All of this is possible due to the high-quality, fine-fiber structure of our absorbents. 

  • Savings on disposal 
    Thanks to the lower weight and high absorption capacity of our DENSORB products, these absorbents are significantly less expensive to dispose of than conventional binders.

  • Optimum safety
    DENSORB absorbents do not present any health hazards, but contribute to a safe and clean work environment. They also help to prevent slips and trips, which are the most common type of accidents in the workplace.

  • Popular choice
    DENSORB offers you the right absorbent for every application, making it one of our most popular products!

How to store absorbents

Absorbents should be protected against permanent UV exposure and stored in a dry place. The temperature hardly plays a role during storage, since the melting temperature is 170 ° C. Oil-bonding agents should always be stored separately from universal and chemical absorbents in order to maintain their water-repellent properties.

It is important to always provide sufficient absorbents within reach of stored substances so that you can react as quickly as possible in the event of a spill.

With our practical DENSORB spill kits, your absorbents are always where they are needed.

What should be considered during disposal?

The absorbents themselves do not pose a safety risk. However, when used the absorbents have the property of the absorbed liquid. Used chemicals and oil absorbents must be disposed of in accordance with legal requirements. The absorbed liquid is decisive. For example, an absorbent mat used to clean up an oil spill must be treated according to the regulations of oil/waste oil disposal. 

Which absorbents should I always have in stock?

According to the HSE an employer must use a risk assessment to determine whether the storage and handling of hazardous substances pose a risk to workers or other persons. In the context of this risk assessment, suitable remedial measures must also be defined.

Check which liquids you handle in daily operation, paying close attention to the type and quantity of the substances and which work is done with them. You should always have enough absorbents available to hold these liquids.

Further down the page you will find all the important information and support for choosing the right absorbent for your needs product. 

Choosing the right absorbent

DENSORB absorbents are available for a wide variety of applications and in many practical forms. So that you can quickly find the right product for your application, we have put together all the important information and decision aids below.

For all applications

DENSORB absorbents are available in many practical formats. Whether for economical use with smaller machinery drip losses or with high daily consumption: 


DENSORB Rolls >>


DENSORB rolls are ideal for covering large areas and are available in different widths to meet your requirements.

All rolls are perforated in the middle and across every 40cm, allowing you to easily tear off the amount required and use only as much as you need. 




Whether for absorbing liquids during maintenance or cleaning work or for the effective control of leaks - DENSORB mats are truly multi-talented.

They enable a need-oriented and economical application in daily operation and are also perfect for long-term use wherever small drip losses have to be absorbed. DENSORB mats are also suitable for absorbing spills and leaks.



DENSORB Schlangen

DENSORB Socks >>


DENSORB socks are indispensable in the fight against leaks. They have a high absorption capacity and are easy to use.

Socks are ideal for use to absorb liquids that have leaked from machines, drums, and in work areas. The flexible polyester case makes it easy to bend the absorbent sock into shape, therefore containing the leak and preventing it from spreading.

DENSORB socks can also reach areas that are difficult to access.


DENSORB Cushions >>


DENSORB cushions have a large capacity and a small footprint, and thanks to their flexible shape, they are ideally suited for reliably absorbing leaking liquids or drip losses in difficult-to-access areas.

A special polypropylene filling provides a particularly good absorption capacity and are therefore perfect for continuous use.

DENSORB Varioform

DENSORB Varioform >>


With DENSORB Varioform you have a product for 4 different formats.

Varioform can be used universally as a roll, mat, snake or cleaning cloth and is suitable for daily use as well as for combating unexpected leaks. The binding material is already provided folded on a roll.

Thanks to the multiple perforations, however, the appropriate format can easily be torn off for every application.

In the practical and space-saving dispenser box, DENSORB Varioform is ideally suited for mobile use or on workbenches and ensures rapid deployment at all locations.

DENSORB Fassauflage

DENSORB Drum Covers >>


When using pumps or funnels on the standing drum, DENSORB reliably ensures that the drum lid remains clean and nothing goes wrong.

DENSORB drum covers are specially designed for 205 litre drums and are exclusively available in UNIVERSAL Version for the absorption of oils, coolants, solvents and non-aggressive acids and alkali.

In our online shop you will find even more practical DENSORB formats such as oil blocks, oil cubes, oil skimmers, oil veils, granules and emergency spill kits.

Material Thickness

Other important criteria for the right product to meet your needs is the level of absorption capacity and its durability. These are, among other things, dependent on the material thickness of the products.

DENSORB rolls and mats are available in two thicknesses.  



Normal material thickness, very flexible and ideal for absorbing small amounts of liquid during repairs, smaller leaks or in production areas.


HEAVY = double absorbing capacity

Extra thick material thickness with maximum absorption capacity.

The high tear strength allows for longer-term use and / or absorption of higher amounts of liquid. 


The higher the durability, the stronger and longer the product can be used and remain in use. Depending on the application, you should therefore consider whether you need an extremely strong durability or whether a normal quality is sufficient for your purposes.

DENSORB rolls and mats are available in 3 different qualities:

In our online shop you will find even more practical DENSORB formats such as oil blocks, oil cubes, oil skimmers, oil veils, granules and emergency spill kits.


High absorption capacity ensures long-term use. 

DENSORB rolls and mats in premium quality are suitable for the highest demands on durability and cleanliness thanks to their multi-layered construction. A two-sided reinforcement of the binding fleece by a liquid-permeable protective layer ensures highest tear and abrasion resistance. Another advantage: Premium quality tapes are lint-free and ideally suited for sensitive applications and surfaces.


Extra quality for high demands on durability and efficiency. 

DENSORB mats and rolls in extra quality have an additional lint-free protective fleece on the upper side. This additional robust layer provides a high tear and abrasion resistance.

Ideal for almost all applications - for example as a hard-wearing floor cover, for long-term use or for cleaning work.


Designed for most everyday applications. 

DENSORB mats and rolls in economy quality are high-strength absorbent material without additional reinforcement on the upper or lower side. They are suitable for economical use in the disposal of small leaks or for daily use in cleaning, maintenance and repair work.
