The term ‘prepreg’ defines a reinforcing tape or a reinforcing fabric pre-impregnated with a resin system. Kordsa, as a global player, serves to the composite industry manufacturing epoxy, hybrid, cyanate ester, polyvinyl butyral (PVB), phenolic and modified phenolic prepregs with different reinforcement matrices such as carbon, glass, aramid and hybrid.
Kordsa provides an extensive product portfolio for industrial, automotive, defense and aviation industries. The products can be also categorized according to their service temperatures so as their glass transition temperatures. Being aware of the customer needs, Kordsa provides autoclave, press and oven curable prepregs.
Kordsa offers both structural, semi structural and visual prepregs for different applications at the desired toughening and tackiness levels. Kordsa’s diversified product range includes fast cure prepregs which are hot moldable and hot de-moldable, significantly reducing tact times for automotive industry. Additionally, it provides special prepregs for fatigue and low fire smoke toxicity (FST) requiring applications. Kordsa with an extensive knowledge on aramid fiber processing for many years, it also supplies ballistic prepregs.

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.
Typical features which we supply in the standard products:
- High stiffness
- High toughness
- Shorter manufacturing cycles
- No need for cold storage
- Recycling potential
