High Performance Plastics for Transmission

When looking for a truly original, sustainable – and good-looking - material for engine covers in the new Mercedes-Benz A-class, the auto giant chose a material that produces just 40% of the carbon dioxide of traditional chemical-based materials. EcoPaXX is a super-light, bio-based polyamide 410 made principally from castor beans - providing the perfect marriage of form and function…  Most importantly the engine cover - used on turbo-powered petrol-engine versions of the new A-Class - needed to perform in temperatures of up to 200°C. EcoPaXX has met this challenge through a deflection temperature under 1.8 MPa load (DTUL) of 200°C.

Meanwhile the reduced weight of the material has enabled the design of an engine cover that can resist high dynamic loads of engine vibrations. In fact the beauty cover weighs just 1.320kg yet…can survive continuous-use temperatures of 200°C, with short-term peaks of 235°C. This in turn has helped Mercedes-Benz achieve a 26 percent fuel consumption improvement based on previous models.

Lighter, tougher crankshaft covers - for Volkswagen

Producing high performance crankshaft covers with lower weight and system costs is every manufacturer’s goal: KACO and DSM joined forces to make it a reality by creating a crank shaft cover based on our biobased EcoPaXX polyamide 410 for Volkswagen.

The replacement of aluminum in this crankshaft cover – part of the MDB modular platform for diesel engines across its Audi, Seat, Škoda, and VW brands - has been achieved with a 45% reduction in weight and system costs.

And of course lower fuel consumption and carbon emissions: EcoPaXX is 70% bio-based and made principally from topical castor beans and is 100% carbon neutral from cradle to gate.

The results: crank shaft covers with zero material waste and even greater energy efficiency.

CVT Transmission Systems: Scoop Snubbers

Automotive | Drivetrain | CV Joints

Stanyl® TW341 PA46 allows for sustainable solutions (up to 1 g/km lower CO₂ emissions) because of lower friction coefficients at elevated temperatures compared to PA66; Stanyl® PA46 allows for reliable solutions (7 times longer life time) due its higher abrasion resistance in comparison with PA66; Stanyl® PA46 allows for cost effective solutions due to faster cycle times in comparison with PA66

Crankshaft Covers

Automotive | Drivetrain | Transmission

ForTii® PA4T, Stanyl® PA46 and EcoPaXX® PA410 allow for light weight solutions (50% less weight compared to metal) and for cost effective solutions (up to 25% lower system/part costs compared to metal); ForTii® PA4T, Stanyl® PA46 and EcoPaXX® PA410 allow for reliable solutions due to good compatibility with FKM/LSR rubbers and to good creep&fatigue resistance in case of Stanyl® and to good temperature resistance up to 150-200°C in case of ForTii® and EcoPaXX®; Xytron™PPS can provide lots of benefits on creep, fatigue&oil resistance, even at elevated temperature.

Engine Cover with Air Inlet Filters

Automotive | Drivetrain | Transmission

Akulon® PA6 allows for reliable solutions due to high temperature resistance (better than PP), great surface appearance (better than PA66) and low warpage levels; Akulon® Ultraflow grades allow even for more cost effectiveness due to 25% cycle time advantage and due to high flowability enabling thinner walled designs

Engine Covers

Automotive | Drivetrain | Transmission

Akulon® PA6 allows for reliable solutions due to high temperature resistance (better than PP), great surface appearance (better than PA66) and low warpage levels; Akulon® Ultraflow grades allow even for more cost effectiveness due to 25% cycle time advantage and due to high flowability enabling thinner walled designs

Engine Covers (close to turbo charged components)

Automotive | Drivetrain | Transmission

EcoPaXX® PA410 allows for reliable solutions to its high temperature resistance (better than PA6), its great surface appearanceand low warpage level; EcoPaXX® PA410 allows for more sustainable solutions due to its excellent carbon footprint (70% biobased) as compared to PA6 and PA66

Pulley covers

Automotive | Drivetrain | Transmission

Akulon® PA6 allows for reliable solutions due to high temperature resistance (better than PP), great surface appearance (better than PA66) and low warpage levels; Akulon® Ultraflow grades allow even for more cost effectiveness due to 25% cycle time advantage and due to high flowability enabling thinner walled designs

Rocker Valve Covers

Automotive | Drivetrain | Transmission

Akulon® PA6 allows for 40-60% weight reduction and better NVH performance versus metal; Akulon® PA6 allows for cost effective solutions versus metal (due to the possibility of function integration) and versus PA66 (PA6 more economical choice); Akulon® Ultraflow grades allow even for more cost effectiveness due to 25% cycle time advantage and due to high flowability enabling thinner walled designs
