Spheretex’ latest product development will be launched at JEC World in Paris from 6 to 8 March 2018.

 “We listen to our customers and take their requests seriously. For this reason we developed Sphere.core PSI, a core material meeting the requirements that many FRP producers were asking for.” says Managing Director Mr. Christoph Esser.

Sphere.core PSIis an advanced solution for making light and stiff FRP laminates in closed mold process.It is a glassfiber-based core material with an internal high-quality flow medium which leads to a steady and fast resin impregnation. Overall part costs could be reduced due to savings in disposable flow media and working time.

This new development is an outstanding alternativefor making light laminates of excellent surface quality – even when applying high vacuum.

Sphere.core PSI is available in 2-5 mm thickness and is suitable for infusion and injection processes such as VIP, LRTM and RTM. It is compatible with common UP, VE and EP resins.

Spheretex has been developing and producing laminatable core materials in Hilden, Germany for more than 30 years. Their range includes a variety of single layer core materials as well as ready-to-use combinations of core material, reinforcement and flow medium. All products are designed to make light and durable FRP parts for many kinds of composite applications, such as marine, transportation, wind energy, pipes, tanks and many more.
