Huntsman enhances production

Huntsman has developed faster processing and reduced production cycles to focus on high-performance chemistries to enable more efficient manufacturing techniques and increase the penetration of composites in to the automotive sector.

For composites to be cost-effective for the mass production of parts, both the manufacturing processes and resin systems need to be adapted. Huntsman has developed epoxy liquid resin systems for out-of-autoclave processes, such as 'high pressure' resin transfer moulding (HP-RTM), which enable production cycles as short as five minutes. Other fast curing epoxy systems, such as expandable epoxy systems (EES), are also available for wet compression moulding. EES allows the easy and exact moulding of complicated shapes and extremely short cycle times between 45-60 seconds at 145-160°C. The company also offers tooling materials for the construction of high-quality, lightweight, heatable composite moulds, which can be used for wet lay-up, resin infusion and high temperature prepreg applications.
