SBHPP in Automotive

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.

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!)

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.

Lubrication systems

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.
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

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.

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.

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

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.

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.

Electrical and Electronic

SBHPP proposes innovative solutions of encapsulation material of protection, moisture resistance and insulation for Electronic modules (ECU), Sensor modules, Power modules.

SBHPP materials are used in electric powertrain, such as wound rotor of synchronous motor whereas mechanical performance, temperature resistance and insulation properties are the key factor.

Tires and rubber goods

SBHPP resins are used for the production of rubber compoundswhich require a high degree of tackiness. It is therefore ideally suited to manufacture any type of tires. A wide range of rosins, terperne, modified terpene or terpene phenolic resins are available to get the best performance and compatibility with any type of associated rubber compounds.

The SBHPP phenolic reinforcing resins are used in rubber compounds where high stiffness and hardness are needed.

Fuel systems

SBHPP high performance engineering thermosets play a significant role in today's advanced fuel systems. Their high dimensional stability, tight molding tolerances and low fuel absorption properties can contribute to increase the pump efficiency by up to 30%.

Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine. SBHPP materials are used in SCR fluid carrying systems where the chemical resistance and compatibility are essential.
