Interface Polymers: Changing the face of Polyolefins. Forever

Interface Polymers: Changing the face of Polyolefins. Forever

Interface Polymers is a spin-out from the University of Warwick. Its unique Polarfin® additive technology is able to modify the properties of common plastics to enable them to stick to and mix with other materials. It’s set to transform the performance and cost competitiveness of polyolefin-based materials across a wide range of market applications. There is great potential to add value across a diverse range of applications in the packaging, construction, agriculture and automotive sectors.

“The ICURe funding enabled me to undertake an intense period of market validation. I spoke to over 100 industrial contacts, that I hadn’t previously known, a significant proportion of whom were very positive about our solutions.”

“Up until that point I had been a junior researcher, inventing and developing Polarfins® in the university lab. ICURe was a big enabler in helping me to take the invention beyond the four walls of the university and to start building a business to commercialise the proposition. It also allowed me to gain a better understanding of how my invention could be developed to satisfy unmet needs in the market.”

“We went through the Options Roundabout in December 2015, with a very positive outcome. We were invited to submit a long-term business plan that forecast a turnover of £100m per annum after 7–8 years. Based on this, we were awarded the Initial Innovate UK grant – which was the key turning point. As a start-up, being first to market is absolutely vital. The grant was paid in advance quarterly over a 12-month period which meant we could move quickly, capitalising on the interest and momentum I had generated in the market validation phase”.

“In 2017, we’ve secured two significant private investment rounds. We will be using the funds to prove the additives work and to scale-up production to an industrial pilot level. In collaboration with the Universities of Loughborough and Warwick, we have also won a second Innovate UK Grant under the Materials and Manufacturing initiative. The aim of this project is to develop a new product variant and production process that will improve the performance of crop protection coverings. We have named this project Polarfin® Green for obvious reasons”.
