  • Vyncolit N.V. (Belgium)

Laboratories

  • High Performance Plastic Products Laboratories

Features

Flexible combination of resin and fiber for specific applications

We offer the best combination of resin (phenolic, epoxy or bismaleimide) and long fiber (glass, carbon or aramid) to meet specific requirements.

High mechanical strength and reliability

Our long fiber reinforced thermoset plastic molding composite has excellent mechanical strength and reliability such as high impact resistance, tensile strength, flexural strength, good creep property under high temperature and dimensional stability for structural parts.

Good moldability (3-dimensional form is available)

Our long fiber reinforced thermoset plastic molding composite is a dry-type composite (solvent free) for easy operation compared to conventional wet-type long fiber materials. Compression molding and transfer molding are available and injection molding technology is under development.
