Absorbents: Frequently asked questions

Not only when buying, but also when storing and handling absorbent materials, questions arise again and again. It is best to find out about the most important do's and don'ts in advance - because if, for example, a leak has already occurred, there is not much time left to clarify open questions. Therefore, we have already compiled the most frequently asked questions on the topic of absorbents for you.

Stocking & Storage

Which absorbents should I always have in stock?

The employer must carry out a risk assessment to determine whether the storage and handling of hazardous substances poses a risk to employees or other persons. Within the framework of this risk assessment, suitable measures for remedial action must also be defined. Check which liquids you handle in your daily operations. Take into account the type and quantities of the substances and which jobs are carried out with them. You should always have enough absorbents available that are suitable for absorbing these liquids.

How long can absorbents be stored? What should be considered during storage?

Absorbents made of polypropylene should be protected from permanent UV radiation and stored in a dry place. Temperature hardly plays a role in storage, as the melting point is 160° C. If these criteria are met, they can also be stored for a long time. The usability of the products should be checked at regular intervals.


Should I test absorbents before use?

We have already tested the compatibility of DENSORB® absorbent materials with various chemicals and presented it in a compatibility list. You can find this list here. Due to uncontrollable influencing factors, DENIOS cannot guarantee 100% absorbency. For your safety, we recommend carrying out a compatibility and absorbency test of your chemicals with DENSORB® binding fleeces before purchase.

What should be taken into account when handling absorbents?

DENSORB® absorbents are made of polypropylene with a melting point of 160°C and an ignition temperature of 430°C. Therefore, they should be kept away from hot surfaces and open flames and should not be used to contain extremely hot liquids.

Caution with used absorbents:

The type and degree of saturation of the absorbed liquid have a considerable influence on the flash point, which can be significantly reduced in extreme cases. Because oil spills and the absorption of volatile chemicals can produce explosive gas or vapour-air mixtures, attention must also be paid to ignition hazards due to electrostatic charges.

After use

How are soaked absorbents disposed of?

Used sorbents must be disposed of in accordance with the legal regulations. The final disposal depends on the absorbed liquid, the properties of which the binding fleece takes on. Binding fleeces impregnated with mineral oil are classified as waste requiring special monitoring and are disposed of in the same way as oily operating materials.
