Thermoplastic Prepregs

Kordsa produces woven based PP and PA thermoplastic prepregs. Matrices of the fiber based thermoplastic composite such as PP and PA have already been used notably in automotive, industrial, sports and leisure industries thanks to their cost saving and light weighting properties as well as being  easy to process with  the low processing temperature and pressure. Kordsa’s product range for polymer matrices is PP and PA6.6. The resin systems are specially formulated by Kordsa, which has excellent compatibility with reinforcing fibers such as E-glass or carbon. Prepreg is available as sheets with maximum dimensions of 1.2 m x 1.2 m. Laminates are usually produced from one to four layers depending on customer requirements. Kordsa’s woven glass fabric based PP thermoplastic prepreg exhibit 25% better flexural properties compared to its counterparts.
