Cost Effective Engineering Solutions through Material Technology
Trends in today’s Automotive industry see a renewed emphasis on durability as well as a continued drive to lower weight and improved fuel economy. But these market trends need to be achieved in a cost effective way. The key characteristics of the SBHPP portfolio are centered around Phenolic chemistry which has a unique position on the cost/performance curve. Durability in terms of Heat and Chemical resistance are a perfect fit for Underhood & Brake systems. Cost performance vs Thermoplastics with the same properties provides a significant economic advantage.

Below is an overview of the pioneering applications developed by Automotive Engineers in partnership with SBHPP.
-
Cooling systems
Molded components in SBHPP materials offer weight and cost savings, combined with improved cooling efficiency in water pumps, impellers, thermostat housings, water inlets & outlets.
1 Water pumps
In water pumps their high mechanical strength and creep resistance withstand the severe side load caused by belt tension and the comprehensive load generated by direct bolting to the engine block (without metal insert!)
2 Thermostat housings, water inlets & outlets and impellers
The exceptional chemical resistance in Long Life Coolants at -40°C / +135°C coupled with the high mechanical strength, retention of stiffness at elevated temperatures and the excellent dimensional stability make glass fiber reinforced phenolics the best choice for thermostat housings, water inlets & outlets and impellers. As additional bonus feature the pump performance increases due to the very smooth surface finish of the impellers reducing fluid cavitation.

1 Oil pumps
Oil pump sliders in SBHPP engineering thermosets are now widely used in variable oil pumps by the automotive industry to replace sintered steel. The huge gain in mass is done without compromising any of the oil pump characteristics.
2 Oil caps
Thanks to innovation development done by SBHPP-Europe some years ago, the use of SBHPP thermosets is progressively extended to the oil pump housings, rotors and blades of variable oil pumps and other specific oil pumps systems like scavenge and COR oil pumps.
Basically, the oil cap can appear as just a small plastic cap which sits on top of the oil inlet. In fact it requires thermal and mechanical properties at optimized cost - offered by SBHPP thermosets - to ensure the engine works properly.

Belts, pulleys and idlers
1 Belts - Rubber tackifiers and reinforcements
SBBHP phenolic resins are used on rubber products, such as accessory belts (multi-v) and timed belts to improve reinforcement, vulcanization and formability. SBHPP offers various types of phenolic resins, tackifiers which have good compatibility with various rubbers.
2 Pulleys - Accessory and toothed pulleys
Multi V pulleys and toothed pulleys manufactured with SBHPP engineering thermosets have a number of benefits. They allow the possibilty of producing pulleys without metal hub insert (excepted press-fit fastening systems) which is resulting in a high cost reduction, a substantial weight saving and eliminates corrosion. The glass fiber and mineral reinforced phenolic material has very good dynamical properties, very low creep, extra wear resistance and no agressivness towards the rubber belt.
3 Idlers and tensioners
Idler and tensionner pulleys offer a weight saving of up to 75 % over a metal version, they run cooler and quieter at all engine speeds and do not require balancing or anti-corrosion treatment.

Transmission, Clutch and Friction
1 Clutch facing
SBHPP resins are the binding component of many clutch facing systems. Various types of phenolic resins are available to provide superior heat resistance, good flexibility, high mechanical strength and good friction properties.
2 Transmission systems
Over the past decades, glass fiber phenolic molding compounds has always been the material of choice to produce torque converter reactors of automatic transmissions. This material withstands the severe loads and environment represented by the automatic transmission oil at elevated temperature.
Many other transmission components are also using engineering thermosets such as pistons, valve systems where the dimensional precision and stability are primordial. For instance, valve block of dual clutch systems made with glass fiber phenolic compound doesn't require extra machining after molding offering a significant cost savings compared to aluminum alloys.Product focus
