At JEC Europe 2013, Johns Manville (Denver, Colo.) said its new, engineered reactive glass fiber is expected to improve performance in structural thermoplastic composite applications. The technology development reportedly has enabled products such as StarRov RXN886, which is ready for testing in the inmold caprolactam polymerization process. According to the company, this fiber maximizes the glass/matrix bonding strength and the multiaxial impact, aging performance and dimensional stability of polyamide-6-based structural composites. It is ready for testing by customers in a variety of processes, including thermoplastic RTM, thermoplastic RIM, thermoplastic pultrusion and thermoplastic filament winding. Also new: ThermoFlow 674 and 601 chopped glass strand for reinforcement of polyamide and polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) engineered thermoplastics, respectively. The products comply with Commission Regulation (EU) No 10/2011 regarding plastic materials and articles that are intended to come in contact with food.
