Crodamide

Crodamide is the world leading range of slip and anti-blocking additives from Croda. Manufacturing for over 50 years, we have gained unrivalled experience and knowledge in production, application and research in this area.

As a speciality polymer additives company, achieving tailored slip performance via the optimisation of product combinations has become one of our technical strengths, and is an exciting area of development for the polymer additives team. By understanding additives at the molecular level, from the seed growing stage onwards, we can offer a superior range of primary amides, secondary amides and secondary bis-amides with precisely controlled functionality.

How do Crodamide additives work?

Crodamide speciality additives are incorporated directly into the polymer during the extrusion process. Products can be added directly to the polymer at the processing stage, pre-compounded or included via masterbatch. They work by migrating to the surface as the polymer cools forming a solid lubricating layer at the surface. This acts to lower the friction or adhesion between contacting polymer surfaces and the polymer and other materials.

What makes Crodamide different to other amides?

Security of supply

The Crodamide range is manufactured at three independent manufacturing sites to ensure maximum security of supply. These manufacturing sites are based in the UK, Netherlands and China. This ensures we can supply product to customer where and when they need it.

We are doubling the capacity of our flagship Crodamide manufacturing site in Hull, United Kingdom, to meet the growing demand of our customers. This £27million investment is the second biggest in our company history and ensures we can continue to offer faultless supply of amides when our customers need it. It will enable improved consistency or product and ensure no variation in application use. More space on the plant will mean more space to deliver new and innovative products that answer the unmet needs of our customers.

Local warehousing allows us to keep stock close to customers and reduce lead times, while back integration of raw materials ensures a consistent and reliable supply chain.

Sustainably sourced and manufactured

The Crodamide range is manufacturied using 100% renewable carbon.  Our crops are grown exclusively for industrial uses, ensuring not only security of supply but robust and sustainable raw materials, that do not complete with food crops. We have long-standing commercial relationships with growers meaning we are able to optimise and utilise our own seed lineage to develop preferential crop characteristics, build in consistency of crop and maximise yield and minimise agricultural land utilisation. For example, over the last 10 years we have increased our crop yield by 26% reducing our reliance on land and allowing more food crops to be grown.   

Sustainable transport options are used where possible to reduce carbon emissions. For example, at our Hull site raw materials are transported by barge, displacing approximately 1000 trips by road tanker. Our on-site wind turbine contributes to our 100% green energy use and reduces our carbon emissions by 2000 tonnes per year.

Effects

Crodamide™ BR (bead)

An bio-based anti-blocking additive suitable for use in a range of polymers. Provides optimal anti-block and film clarity when used in combination with inorganic anti-blocking solutions

Crodamide™ SRV (Bead)

A bio-based refined steramide in bead form that provides anti-blocking performance to polyolefins and rubber at low temperatures.

Crodamide™ EBO (Bead)

A secondary bis amide providing a medium slip and anti-block effect in polyolefin polar copolymers. It is particularly useful as an anti-tack additive in EVA pellets and hotmelt adhesives.
