A range of resins derived from natural  vegetable oils (Rapeseed, Soybean, Sunflower), aromatic plant oils such as Cashew Nut Shell Liquid (CNSL) or oils produced by algae. Bioresins can be used as sustainable alternatives to traditional petro-chemical materials resins as the adhesive matrix in the manufacture of a wide range of composite products, such as wood-based panels and fibre reinforced mats.

Cambridge Biopolymers technology uses naturally hydrophobic plant oils as starting materials for a range of resin products. The plant oil is transformed to a resin precursor that will polymerise when heated in the presence of an acidic or alkali catalyst. Typically, these resins can be used as formaldehyde-free alternatives to replace urea/phenol/ melamine formaldehydes and isocyanates in various applications.

The 'bioresin' technology uses the natural reactivity of ozone to attack the double bonds present in the oil, forming oxygen linkages that can be converted into crosslinkable units. Other resin products made from natural raw materials  employ chemicals to epoxidise the double bonds prior to polymerisation, but we have found ozone activation is an effective approach, which provides a very clean and efficient synthesis whilst generating little or no waste by-products.

Arabinoxylan (AXF)

A thermo-stable gellable material extracted from maize or wheat bran with proven utility as a de-briding agent in wound dressing and potential applications as a food ingredient and as an adjuvant for vaccine delivery.
