Johns Manville (JM) has introduced a new pioneered engineered reactive glass fibre for improved performance in Structural Thermoplastic Composites.

According to JM, this technology development has enabled products such as StarRovRXN886, which is ready for testing for use in the in-mould caprolactam polymerization process. It explains that StarRovRXN 886 maximises glass-matrix bonding, resulting in improvements in strength, multi-axial impact, aging performance, and dimensional stability of polyamide-6 based structural composites. The technology and product is ready for testing by customers in a variety of processes, including TP-RTM, TP-RIM, TP-pultrusion, and TP-filament winding.

JM also introduces two new chopped strand materials, ThermoFlow 674 and 601, for glass reinforcements in polyamide and PBT/PET engineered thermoplastics, respectively. These materials were developed to reinforce engineered plastics in compliance with COMMISSION REGULATION (EU) No 10/2011 of 14 January 2011 on plastic materials and articles intended to come into contact with food. JM explaisn that the new ThermoFlow 674 and 601 chopped strands, as well as ThermoFlow636 used in polypropylene, provide material engineers the needed flexibility to enhance thermoplastic performance when plastic materials and articles are intended to come into contact with food. This new offering is expected to further boost the use of engineered polymers in the consumer segments, such as electrical appliances.

Enno Henze, Vice President and General Manager for Engineered Products Europe/Asia stated, “Over the last couple of years we have focused our research and development activities on enhancing our product portfolio of chopped strands for the reinforcement of thermoplastic polymers. And the efforts are truly paying off.  Our ThermoFlow product line enables our customers to engineer reinforced polymer compounds with outstanding mechanical performance and chemical resistance whether they are based on polyamides, polyesters, polypropylene or specialty polymers. With our recent expansion of the Trnava, Slovakia facility, we are in a great position to support the growth agenda of our customers.”
