Reutlingen, Germany – BASF's Elastocoat C6226/107 a polyurethane resin for pultrusion that is stable at up 200° C has won an Award.
The material gained an Innovation Award in Foamed Plastics and Polyurethane 2019 from the FSK – Fachverband Schaumkunststoffe und Polyurethane
Polyurethane resins offer advantages over other pultrusion resins. They have lower viscosity so they wet the fibres well and can be pulled at low forces.
The new formulation has an 'innovative catalyst which makes it possible to process at up to 200° C.
BASF said that this means it could be used in automotive or construction applications. The matrix material is suitable for both glass- and carbon-fibre reinforcements.
The company said that it has developed lithium chloride salt-based complex catalyst. This is used with an epoxy and internal mould release and controls the reaction pathway between PU and PIR. The balance of reactions can be fine-tuned in innovative ways. This system produces PU-rich and PIR-rich nanoscale segments.
.The new formulation has a combination of temperature and chemical stability of a PIR bond and non-brittle PU mechanical properties,' explained Julia Liese, Laboratory Manager in Polyurethane Research at BASF.
The award was presented at the FSK meeting in Reutlingen in mid-November.
