DSM Engineering Plastics polyamides used for transmission sensor Two glass reinforced polyamides from DSM Engineering Plastics are used for the housing and rotor for a transmission sensor used on heavy-duty full size and commercial trucks.
Wabash Technologies selected Stanyl* for the transmission sensor used on heavy-duty full size and commercial trucks. Stanyl TW200F8 (40% glass reinforced polyamide 46) is used for the main body of the sensor and Stanyl TW271F6 (30% glass reinforced polyamide 46) is used for the rotor. The sensor, which determines whether the transmission gear is in park, neutral, or the various drive gears, demands high temperature transmission oil resistance, high temperature stiffness (150°C) peaks to 170°C, and excellent wear resistance. Polyamides are well known for their resistance to a wide range of chemicals. Stanyl is no exception. At higher temperatures its resistance to oils and greases is excellent. Due to its high crystallinity, Stanyl retains a high level of stiffness up to temperatures very close to its melting point. This provides wider safety margins for critical applications than standard engineering plastics (e.g. PA6, PA66, and polyesters). Stanyl has an excellent wear resistance and outperforms other engineering/high performance plastics under most conditions but especially at higher temperatures or high torque/loads.
DSM engineers provide OEM’s and suppliers with the technical support they need to turn their innovations into successes delivering added value through knowledge, performance, and confidence. The cover of the sensor and the interface of the body needed to be flat and match up so the two parts could fit together and be ultrasonically welded. Engineers were able to provide design assistance, mold flow and gating recommendations for part dimensions allowing for the successful design of this sensor. Wabash Technologies DSM Engineering Plastics is a business group forming part of DSM's Performance
Materials cluster. DSM Engineering Plastics is a global supplier of Stanyl
PA46 and Akulon* 6 and 66 polyamides, Arnitel* TPE-E, Arnite* PBT and
PET polyesters, Xantar* polycarbonate, Yparex* extrudable adhesive resins,
and Stamylan* UH Ultra High Molecular Weight PE. These materials are used
in technical components for electrical appliances, electronic equipment
and cars, in barrier packaging films as well as in many mechanical and
extrusion applications. The business group had annual sales of EUR 705
million in 2005. With Stanyl, it is the global market leader in high-heat
polyamides. Read a recent press release from DSM about; 'An Italian company Badinotti, manufacturer of aquaculture nets for commercial fishing, introduces a new predator net for protection of farmed fish made with fibers from DSM.'
