Polyamide replaces metal, rubber automotive parts
A polyamide thermoplastics is finding increasing use as replacement for metal in assemblies that have traditionally been made of metal and rubber.
Fibre and film added to plastics portfolio
Stanyl, a high-heat polyamide 4,6 (PA46) resin from DSM Engineering Plastics, is adding a new market segment, fibre and film to its existing broad portfolio.
By limiting thermal oxidative breakdown, Stanyl Diablo withstands more than 3,000h temperature exposure up to 230 deg C with less than 15% loss in mechanical properties.
Requirements for Under The Bonnet (UTB) applications are changing constantly.
Environmental requirements, EURO V and VI legislation and the call for reduced fuel consumption have resulted in significant changes, e g, the use of smaller engines with higher turbo pressures and EGR (Exhaust Gas Recirculation).

Engineering plastics improve characteristics
Latest innovative engineering plastics developments include materials for automotive 'under the bonnet' products and improved materials for injection moulding.
Resin development lowers moulding costs
Compared with existing, standard resins, a product shortens production cycles in injection moulding and packaging to lower costs per part.
As a consequence, automobile UTB components such as air ducts, air intake manifolds and charge air cooler end-caps are exposed to continuously rising operating temperatures.
With increasingly critical temperature and tougher life time requirements, long term service life of components made from current thermoplastics can be at risk.
Turbo Systems Application Development manager at DSM, Ton Vet, said that continuous temperature levels up to 230 deg C are now increasingly common for UTB applications.
Vet added: "Stanyl Diablo OCD2100 outperforms current high heat resins on high temperature stability, but also on weldability, weld strength and the weld's long term heat stability".
He said: "Longer and better lifetime reliability of parts is also possible because of the material's low creep and its fatigue behavior.
Part design and function can be reached more easily and, more importantly, UTB part reliability can be guaranteed for the lifetime required".
Global marketing manager Stanyl, Dan Bishop, said: "With Stanyl Diablo OCD2100, metal replacement options have been expanded tremendously.
In addition to the cost reduction that can be achieved by replacing metals, the use of Stanyl Diablo OCD2100 also offers possible cost down options for applications running in specialty materials such as PPS".
Bishop added that Stanyl allows the cost effective design of UTB applications, owing to the following factors.
* Excellent retention of stiffness at elevated temperatures.
* Superior toughness levels.
* Resistance to greases.
* Ease of processing, especially when compared to other high performance materials such as PPS, PPA and PEI.
After an intense study of both chemical and physical degradation mechanisms, DSM Engineering Plastics' R and D Department was able to identify the exact material properties that needed to be controlled in order to develop this next generation of high temperature resistant Stanyl Diablo grades.
Product development specialist for Stanyl, Willy Sour, underlined that this fundamental knowledge of the exact degradation mechanism was the key to Stanyl Diablo's success.
He said: "Stanyl Diablo does not only rely on traditional anti-oxidants, as is the case for competitive products.
By actual control of the oxidation mechanism, loss of mechanical performance is effectively reduced, as shown in the attached pictures of cross sections of long term heat treated test bars.
That is why Stanyl Diablo is able to offer best-in-class long term heat stability".
