Stanyl nylon 46 for VW intercooler endcaps

DSM Engineering Plastics (Sittard) : 04 March, 2004  (Application Story)
Stanyl TW200F6 has been selected for the intercooler end-caps of Volkswagen.
Stanyl TW200F6 has been selected for the intercooler end-caps of Volkswagen. The end-caps are connected to both sides of the aluminium intercooler body. Hot air with a temperature up to 210C enters at one side and is cooled down in the intercooler. The aluminium intercooler and the plastic end-caps need to be capable of withstanding intermittently applied pressures of up to 2bar.

To ensure the sealing integrity to the aluminium body at the elevated temperatures encountered, the material used for the end-caps has to have a high modulus and excellent creep and fatigue resistance.

Stanyl TW200F6 a high temperature resistant PA46 reinforced with 30% glass fibres - offers a unique combination of stiffness, high fatigue resistance and excellent heat-ageing resistance while at the same time providing a high quality surface. In addition, Stanyl has excellent flow properties and its fast rate of crystallization lead to short cycle times.

Intercoolers cool down turbocharged air and this allows maximum power to be obtained from - mainly diesel - engines. The use of a turbocharger in combination with a charge air cooler allows car manufacturers to equip cars with smaller and lighter engines which are more environmentally friendly.

The full Stanyl family of PA46 formulations is produced and marketed exclusively by DSM Engineering Plastics and delivers a performance similar to high end materials such as liquid crystal polymer (LCP), polyphenylene sulfide (PPS) and polyetheretherketone (PEEK) combined with the ease of processing and design of PA6, PA66, polybutylene terephthalate (PBT) and polythene terephthalate (PET).

Stanyl formulations provide resistance to high temperatures, good mould flow behaviour, excellent mould and tooling longevity, and overall economy of processing. Stanyl PA46 is offered in a wide variety of grades, including unfilled and reinforced (glass fibre and mineral), self-lubricating, impact-modified, and flame-retardant.
