Awarded by a JEC Innovation Award 2010 in the category Bio-Based Materials, Hunstman will also present at JEC Show Paris a new range of composite bonders and its third nanoreinforced composite RTM system.
JEC Innovation 2010 Bio-Based Materials Award
Huntsman has supplied the Lineo development team with resin solutions for both pre-treatment of flax fibres and final impregnation which allows the incorporation of renewable materials in composite products without any loss of mechanical performance. The result is a winning flax yarn based prepreg for vibration damping applications which makes it particularly suited to the sports market for products such as tennis racquets and bike frames, and which illustrate the involvement of Huntsman in sustainable and eco-friendly chemistry. By leveraging our core competencies, which include synthesis and formulation, testing and analysis, process manufacturing technology and technical service, we can develop sustainable products that benefit our customers, consumers and the planet as a whole.
New Specialist Adhesives For Bonding Composite Parts
Adhesives have numerous advantages over mechanical joining techniques. This becomes even more obvious when it comes to the assembly of dissimilar substrates as well as lightweight composite parts. Bonding allows a uniform distribution of strain and stresses across the joint, which makes it the ideal technique to join composites of different constitution.
Due to this increasing need in specialised adhesives, Huntsman Advanced Materials is launching a new range of composite bonders, consisting of the high temperature resistant system Araldite® AW 4858 / Hardener HW 4858 as well as the high-strength Araldite® AW 4859 / Hardener HW 4859. Both epoxy based adhesives are available in cartridges, and display lap shear strengths of up to 40 MPa on composite parts. The methacrylate based adhesive Araldite® 2048 has been developed especially to meet the need of bonding untreated composite parts. In contrast to the high-strength epoxies, this product is more balanced in terms of strength and flexibility, and is performing well even on otherwise difficult to bond surfaces. The range is completed by a pair of silane modified, one component, moisture curing adhesives, Araldite® 2060 and Araldite® 2061. Both products are highly flexible, over-paintable and show superior durability and weather resistance. Araldite® 2061 is black in colour in order to match a composite look.
All of the above mentioned products are phthalate-free, with Araldite® 2060 & 2061 not even carrying a hazard symbol.
Third Generation Toughened High End Araldite® NanoTech Composite RTM system
Following the successful application of this patented new nanotechnology for ice hockey sticks, this system is attracting a great deal of interest from sport, automotive, marine and other sectors. This revolutionary new technology significantly improves fracture resistance without affecting other vital physical properties such as flexural modulus, temperature resistance and viscosity. The result is a material with exceptional mechanical properties of strength and the ability to withstand shock without developing micro-cracks making it superior to standard resins.
Hunstman will be exhibiting on Booth G65 at JEC Show Paris on April 13, 14 & 15, 2010.
