An insight into new halogen free flame retardant TPEs

Ryosuke Kurokawa from Sumitomo Chemical will be discussing new halogen free flame retardant TPEs at this year's Thermoplastic Elastomers Summit. We spoke to him ahead of the event to hear more.

Smithers Rapra: Your presentation looks at new halogen free flame retardant TPEs; can you briefly go into what this entails?

Ryosuke Kurokawa: Our developed HFFR-TPEs lead to an eco-friendly way of reducing the risk and damage from fires, as those materials can suppress a carbon monoxide and smoke generation. (* HF: halogen free, FR: flame retardant)

Smithers Rapra: Your presentation looks at a number of applications for this technology, why is it important to share this with the industry?

Ryosuke Kurokawa: Our HFFR-TPEs don’t contain halogen based FRs and are eco-friendly materials. Then, they are flexible and easy to mold and can be used for wide range applications such as train car, photovoltaic module, architecture gasket and so on.

Smithers Rapra: Within the industry you serve, what changes or developments have you noticed recently?

Ryosuke Kurokawa: Halogen based FRs tend to produce hazardous halogen gases during combustion. Therefore, there is a strong demand from the market for halogen free based FRs in terms of health and safety reasons.

Smithers Rapra: What do you think the impact of these developments will be on the remainder of the industry and supply chain?

Ryosuke Kurokawa: The halogen based FR-TPE should be the only product having both excellent flexibility and high flame retardancy which meets UL 94V standard. By combining the FRs and the FR auxiliary, high flame retardancy was achieved without using a halogen based FRs. Those new HFFR-TPEs with both flexibility and flame retardancy at a high level will replace the halogen based FR-TPE.

Smithers Rapra: What are you most looking forward to by attending the TPE World Summit 2017 conference?

Ryosuke Kurokawa: We would like to hear information about the market and meet new customers at the conference.
