trials and testing


We recognise that every Client will have their own materials and formulations and that these may respond differently to HSM processing.


Watson Brown will carry out small scale trials on your materials to verify the process and characterise the operating parameters.

For the in-house recycling of materials, two scales of trial are typically carried out:

  • characterisation trials

    Small scale trials usually performed on a bench-top machine.   Sample sizes range from 20g to 100g. (Usually 5kg of materials supplied by customer). Testing of mechanical and chemical properties can be carried out at this scale Sample materials and report sent to customer

  • process trials

    Laboratory scale trials usually performed on a 2 litre laboratory machine.   Sample sizes range from 1kg to 20g.  Testing of mechanical and chemical properties can be carried out. Process trials carried out at Customer site to ensure

  • Further large scale trials can be carried out to ensure full process acceptability, usually based on materials generated by a 20 litre HSM system.


    For application trials, suitable applications are manufactured and tested to suit.


    Dependant on the nature, magnitude and priority of the trials, a small charge to cover direct costs may be requested.


    Watson Brown has carried out a number of trials on customer materials. Information on these trials and their results cannot be distributed due to the confidential nature of the information that they contain. A limited set of results generated by Watson Brown and third parties is available to registered users of this website. These results include the results from:

  • trials on EPDM automotive sealing materials
  • trials on Nitrile gasket materials
  • trials on tyre tread materials (NR and SBR) for standard and laboratory materials
  • application performance trials
  •   Please contact Watson Brown for registration details in order to view these results or to request trials on your own materials.

    disclosure

    All trials are carried out under the cover of a Non Disclosure Agreement (NDA).

    The standard Watson Brown NDA is provided here.

    Please print and sign two copies and send them to Watson Brown before sending any materials for trials.

    One fully signed copy of the NDA will be returned to you for your records.
