Product overview

Our range of high quality CARADOL* polyether polyols are derived from propylene oxide. When reacted with isocyanates they form polyurethanes, which are used in a number of product applications such as flexible and rigid foams, and in Coatings, Adhesives, Sealants & Elastomer (CASE) systems.

As a result we may encounter them in a wide variety of products including furniture, car seating, bedding, building insulation, paints and coatings, artificial sports tracks, playground surfaces, ski suits and other waterproof leisure wear.

CARADOL polyether polyols are available in a wide range of molecular weights that meet the application and processing needs of flexible foam and non-foam (CASE) manufacturers.

Polyols can also be used in non-urethane applications such as surfactants and oil demulsifiers.

Our strengths in polyether polyols 

  • Consistent high quality CARADOL products based on leading technologies
  • World-class integrated manufacturing sites
  • Global supply and logistics capability
  • Expert R&D, focused technical support and professional customer service
  • High standards of HSSE and product stewardship

Product Safety

We share our HSSE standards, knowledge, experience and best practice with customers. An example of this is our commitment to sharing and applying standards for handling Toluene Diisocyante (TDI), an essential ingredient in polyurethane manufacture, along with polyether polyols.

Our global sales team use information on product handling, HSSE risks and controls, and Emergency Response to provide customers with timely, quality advice. We engage with customers, distributors, transporters, industry associations and government agencies to promote an attitude to safety that goes beyond compliance with regulatory requirements.

Emergency information 

By providing local 24-hour emergency contact numbers on up-to-date Material Safety Data Sheets and drum labels and maintaining our HSE training material and checklists on the Customer Lounge website, we ensure that customers have 24-hour access to the information they need in case of an emergency.

Discover the world of polyurethanes 

Polyurethanes are all around us. They are innovative and durable and their properties can enhance resource efficiency in applications such as buildings and cars. Discover more about the world of polyurethanes in this animation, which has been produced by ISOPA – the European Diisocyanate and Polyol Producers Association.

Polyols for foams

Shell Chemicals companies produce a wide range of polyether polyols to suit customers’ varying requirements in respect of processing latitudes and end use properties. As well as producing conventional polyols, we offer co-polymer polyols with varying Styrene Acrylonitrile (SAN) solids content to enhance the foam's load-bearing capacity. We also offer polyols for producing High Resilience (HR) foams with improved comfort characteristics as well as polyols to produce moulded foams.

Applications

Have you ever thought what your average day would look like without a mattress? A comfortable sofa? A car seat? Dishwashing sponges?

Polyurethane (PU) flexible foams are lightweight, durable and have excellent energy absorbing characteristics. CARADOL polyether polyols are the main base material for polyurethane flexible foams used, in applications such as:

  • Mattresses
  • Automotive seats, interior parts and sound deadening
  • Upholstered furniture

Polyether polyols are a major component in the production of rigid foams. These foams are typically used in insulation panels, as well as in structural and decorative moulded items.

Polyols for CASE

Shell Chemicals companies are among the leading CASE (Coatings, Adhesives, Sealants and Elastomer) polyether polyol suppliers.

CASE systems are among the most versatile of urethane applications and are characterised by their light weight, great durability and unique low temperature mechanical properties. They are often preferred to alternative materials as they can be formulated to deliver tailored performance properties for specific end-uses in the automotive, construction and surfacing industries.

A new production process incorporating proprietary continuous process technology has enabled a significant expansion of our CASE production capacity. The continuous process also delivers some advantageous product properties. The polyols typically have fewer by-products, leading to less odour and less volatile organic compounds (VOCs) than those made via a batch process.

Examples of CASE urethane systems are:

  • Adhesives that glue the glass into a car window frame, giving the car structural stability and forming a seamless seal between the metal and glass
  • Adhesive that bonds rubber scrap into tiles
  • Micro-cellular moulded elastomer that covers the metal frame in a car steering wheel
  • Elastomeric sheets that dampen the sound and vibrations under rail tracks

Formul8

Formul8 software

Formul8* is a software package that predicts flexible slabstock polyurethane foam properties and costs from formulation input data.

Available exclusively to key CARADOL polyol customers, the software can help to reduce much of the time-consuming calculations and trial and error development needed in making predictions about foam qualities. 

Following training from a Shell Chemicals technical representative, Formul8 can be used to:

  • develop new foam formulations
  • calculate foam costs 
  • modify formulations to ensure consistent foam quality in variable climatic conditions 
  • select the lowest cost foam formulation to produce specific foam properties 
  • provide fire warnings associated with high risk formulations 
  • limit the processing problems associated with unsuitable formulations

Formul8 is only available via the Customer Lounge. It is available in eight different languages: English, French, Italian, German, Mandarin, Portuguese, Spanish and Dutch. 

Software updates are available to:

optimise foam formulations to obtain specified foam properties

customise the database with input from the customer's slabstock machinery to maximise the accuracy of prediction

ease the introduction of new CARADOL grades
