Compound developments

Recent progress in plastic material has seen a number of new compounds enter the market that give designers superior properties

PolyOne has launched a long-fibre thermoplastic compound that is optimised for surface finish, stiffness and impact strength. The OnForce gives higher performance and better aesthetics, and can typically be used in metal replacement and structural applications.

It also retains its performance and properties across a wide temperature range, from -20°C to 160°C. Furthermore, it offers improved creep and fatigue performance, better dimensional stability, very good chemical resistance, and exceptional surface finish when compared to highly filled short-fibre products as well as other long-fibre thermoplastics.

Craig Nikrant, vice president and general manager of PolyOne Specialty Engineered Materials, says: "OnForce compounds are another example of PolyOne's ability to address design, processing, and market needs in developing new materials."

Additionally, UK firm 4Plas along with AD Majoris have been focusing efforts toward compounds for specific applications where they can bring cost and technical advantages to the end product. It has developed a long glass fibre reinforced polypropylene, which is being used by Jaguar.

AD Majoris is becoming a market leader in naturally filled compounds with the introduction of mixed fillers combining natural fibres and glass fillers where higher heat and greater stiffness is needed. Majoris has also overcome the old problems of burning, odour and colour previously experienced with naturally filled compounds.

Pointers

* A long fibre thermoplastic compound optimised for finish, stiffness and impact strength

* AD Majoris has developed a low cost long glass fibre reinforced polypropylene, which is currently being used by Jaguar
