Under the hood – thermo resistant polymers and the automotive industry

Stanyl polyamide 46 was introduced approximately three years ago in the automotive industry by DMS and since then, the popularity of high temperature polymers for under the hood applications increased significantly. These high-performance materials offer plenty of advantages, being suitable for various car parts, as the manufacturer declares. The first car part manufactured from this material was an air intake manifold with integrated charge air cooler. Below you will find more information regarding these materials and their use in the automotive industry.

Biobased materials will take up to 200ºC

Biobased materials are generally used for crankshaft covers, a crucial element which can be found under the hood of all vehicles. An intricate element, with an incredible design and care and attention for details, this element must meet certain requirements in order to offer an incredible quality and to meet all the necessities of the industry. For these elements, biobased materials have proved to work just perfectly. They are easy to mold into the desired shape, so they can seal tightly and minimize warpage. Due to the high temperatures that can usually be found under the hood, high temperature polyurethane is just perfect material for these elements, being a great alternative to various lightweight metals. And since we mentioned lightweight metals, we should also mention that these materials are also incredibly light, which makes them perfect for this industry. Also, since this material is so resilient, it will successfully survive for the numerous fixing bolts usually installed with it.

PA6 – the preferred material for oil sumps

Weight-reduction wise, oil sumps offer a great opportunity for all manufacturers in the automotive industry. Because of this reason, manufacturers choose to invest in PA6 in order to reduce the overall weight of a vehicle. Because of its amazing qualities and resilience, this material is perfect for the somehow exposed position of oil sumps. Being vulnerable to rocks flying on the road when driving the necessity of a resilient material emerged. And the French manufacturer Steep Plastique developed these parts from alternate materials in order to reduce weight by 60%, and increase resilience on the road at the same time. For the oil sump, the manufacturer used a glass reinforced and heat stabilized and oil resilient polyamide 6.

PA46 – an incredible heat resistant material

We mentioned in the beginning that the first heat-resistant air manifold was introduced on the market by DMS and since then it knew a great success. Although during the development phase there were incredible challenges regarding the high temperatures and high internal pressure under which these elements are put through. However, with an intelligent cooling system and with increased heat resilience, the PA46 can take up to 250ºC. This makes it just perfect for applications in the automotive industry.

These are only a few of the most popular high temperature polymers that are currently used in the automotive industry. PET is also popular, and there is expected to emerge on the market an increased number of other heat-effective materials.
