France’s Arkema group has introduced a new family of thermoplastics which combine the properties of polyamide with those of polyolefins, “by producing co-continuous morphologies on a nanometric scale,” it says.
Trade named Apolhya, the range is claimed to offer better thermal stability than polyolefins, enhanced flexibility over conventional polyamides and good impact and chemical resistance.
The company envisages applications as halogen free flame retardants which are easier to process than cross linked polymers, as a compatibiliser or adhesion promoter in recycling of polyolefins and polyamides or as a performance enhancer in thermoplastic elastomers.
In addition, says the company, Apolhya’s manufacturing process allows properties to be tailored to specific requirements for particular applications and additives such as stabilisers, pigments and fillers.
Arkema claims to be the leader in the field of nanostructured materials with strengths both in carbon nanotubes through its Graphistrength powders as well as in acrylic block copolymers and is also cooperating with other companies such as Zyvex, in the US, in the field of enhanced epoxies.
