Introduction

PH 840 is a halogen-free modified phenolic system, designed for laminate with bright colour and good surface quality.

This prepreg material has been developed for industrial and rail applications with high specific mechanical properties and excellent FST (low heat-release and smoke-density) behaviour.

PH 840 can be cured between 120°C and 160°C (248°F and 320°F). Monolithic and sandwich structures can be easily manufactured with this prepreg. The curing can be performed by press, vacuum and autoclave moulding with a pressure of at least 0.7 bar / 10 psi. Such composite structures can be exposed easily to temperatures in the range of -55ºC up to +80ºC.

Applications

PH 840 prepreg is suitable for:

  • Rail industries
  • Machine industries
  • Marine and automotive applications
