1 Automotive Thermosets Rev-up Performance, Design, and Efficiency Dow Elastomers

2 Bumper to bumper, we ve got an elastomer for your automotive thermoset part Elastomers play a significant role in the auto industry and continue to give engineers and stylists exciting options for inspiring new designs. These versatile materials are critical to a car s coolant system, air conditioner, power steering system, engine, brake system, belts, electrical system, and more. Dow offers exceptional elastomer choices for the varied functions and performance characteristics you are looking for. Belts, hoses, and molded gaskets made with NORDEL EPDM are longlasting and more consistent to produce. Weatherstripping, belts, and vibration isolation parts made with NORDEL EPDM resist heat and nature s elements to keep working for consumers and give manufacturers lower production time. In addition, producers will get a high performance-to-cost advantage when they use TYRIN Chlorinated Polyethylene (CM) resins on a variety of parts from hoses and tubing, to wire and cable jacketing. Selecting a Dow elastomer presents groundbreaking possibilities for both you and your customers. Underhood and powertrain When you need to adjust to industry developments, Dow elastomers offer solutions. Dow s commitment to innovation has bred elastomers based on the needs of extended warranties, higher engine temperatures, the call to reduce emissions, and more. In choosing a Dow elastomer, you will be ready to handle the emerging needs for building the underhood and powertrain of a vehicle.

3 Cooler solutions Coolant hoses need to handle continuous exposure to heat and resist deterioration from coolant fluids. Hoses made with NORDEL EPDM will do both, with the added benefit of exceptional processing in hose fabrication. Transmission oil cooler and engine oil cooler hoses need to deliver heat and oil resistance at an even higher level. TYRIN CM resins offer heat resistance at 135 to 150 C and exhibit exceptional oil and ozone resistance giving hoses made with TYRIN resins the potential for a much longer life. Power steering hoses require a refined balance of heat resistance and strength. TYRIN resins couple strength with heat resistance for impressive performance at a low cost. Additionally, air conditioner hoses need exceptional heat resistance to survive under the hood. NORDEL EPDM offers improved heat resistance (to 150 C and beyond) for the air conditioner hose tube and cover. Changing the way the wind blows When forming air intake ducts, you need a material that is easily processed. TYRIN CM resins and NORDEL EPDM are easily molded into large diameters and convoluted geometries necessary for duct creation. Cleanside ducts require high resistance to oils, residual fuel, heat, and ozone. TYRIN resins offer excellent resistance to all of the above. Return air ducts also need long-term heat and ozone resistance. NORDEL EPDM provides impressive heat and ozone resistance for longer life expectancy of ducts.

4 A fashionable trend Accessory belts need to hold up to high temperatures to do their job. NORDEL EPDM provides excellent resistance to high temperatures for long service in standard and multirib-fead (Front End Accessory Drive) belts. Power up As electrical systems have close proximity to the engine, they need to be heat and oil resistant as well. TYRIN Chlorinated Polyethylene resins are used for ignition wire and battery jumper cable jackets and provide exceptional heat and oil resistance, protection against ozone and chemical damage, and flexibility. In electrical systems, it is important to have good insulation. Insulation and spark plug boots made with NORDEL EPDM deliver exceptional electrical performance and resist high engine block temperatures. Dow elastomers combine to create top-notch performing electrical systems designed to last. Chassis and underbody Dow elastomers that go beneath the vehicle and in the chassis are critical to the braking, steering, and suspension systems and add the reliability your customers look for in a vehicle. Stop settling for average. Go with Dow elastomers. Safety is one of your customers main concerns. Brake hoses, for example, made of NORDEL EPDM provide exceptional performance in the most critical of automotive safety systems. Tire sidewalls need to maintain their properties under enormous pressure. NORDEL EPDM provides exceptional ozone resistance that helps provide longterm protection and the black color of the tire in addition to reducing or even eliminating the need to use expensive chemical anti-ozonants during production. Its high molecular weight, low ethylene content, and granular form are why it has excellent processability. Additionally, when making tire inner tubes, NORDEL EPDM improves processability. Its low viscosity and low ethylene make it compatible with butyl rubber for easy blending. SOFT, DURABLE DOOR PANEL, CONSOLE, AND ARMREST SKINS BELTS 4

5 Elastomers that can stand the heat and the friction and the elements From hoses to tires, Dow has the elastomers you re looking for. Dow s commitment to innovation is critical for taking care of your emerging needs as the auto industry changes. These elastomers present inspiring options for both you and your customers. TYRIN Chlorinated Polyethylene Resins For everything from power steering hoses, to transmission oil cooler hoses, to battery jumper cable jackets, TYRIN Chlorinated Polyethylene Resins offer an unmatched performance-to-price ratio. The resins high-level resistance to heat, oil, and other automotive fluids make these materials an obvious choice for hoses, tubing, air ducts, and other high performance underhood components where close engine proximity is an important factor of selection. The ability to resist heat at 135 to 150 C will give parts made with TYRIN resins the potential for a much longer life. TYRIN resins are soft thermoplastic modifiers that increase impact resistance. They are excellent impact modifiers of rigid ABS (acrylonitrile butadiene styrene) and PVC (polyvinyl chloride) systems. The resins contain no plasticizers, so they do not contribute to fogging of windows. TYRIN resins are also easily molded, so they can be contorted into abstract shapes for air intake duct components. NORDEL EPDM NORDEL EPDM is a next generation ethylene propylene diene monomer with very low gel levels that gives manufacturers the chance to achieve improved levels of consistent production and appearance in elastomeric goods ranging from belts, to coolant and brake system hoses, to air intake ducts. NORDEL EPDM products offer resistance to heat and fluid deterioration, making them an excellent choice for belt, hose, insulation, and spark plug boot production. Their exceptional resistance to high engine block temperatures gives brake hoses, cups, and boots molded of NORDEL EPDM top-notch performance for automotive safety systems.

6 Key Benefits Temperature range: -40 to 150 C Inherently ozone resistant Excellent resistance to sunlight, weather, and UV exposure Color and odor free Resistant to coolants and brake fluids Impact resistant Cleanliness for high quality surfaces Temperature range: -35 to 150 C Oil and grease resistant Thermoplastic and thermoset uses Ozone resistant Convenient powder form NORDEL EPDM is also easily molded, making it an excellent material for air intake ducts that need to be molded into various geometrical configurations. NORDEL EPDM is a good choice for weatherstripping, coolant hoses, hose covers, engine mounts, and muffler hangers. Its high molecular weight allows for high filler and oil acceptance for fast processing and strong mechanical properties, while also providing heat and weather resistance. These durable products are easily processed and help provide economical, longer lasting, and safer parts for your customer.
