FaraPack Polymers has access to stocks of well-characterised polymeric materials. One of the key areas of expertise is the synthesis of a wide variety of block copolymer combinations, molecular weights and architectures. These can be used either for research purposes or industrial testing. They have been used in a variety of applications including tissue engineering, adhesives, fibre formation, colour effects, etc.

Outlined below are examples of some of the techniques, architectures and materials either currently available or available at moderately short notice to illustrate our capabilities. If you are interested in finding out more about any of those shown or have a specific enquiry you would like to make then please contact us.
