Blends based on nitrile rubbers are used in underground wire/cable covering automotive weatherstripping, spoiler extensions, foam-integral skin core-cover armrests, and window frames footwear and flexible, lay-flat, reinforced, rigid, and spiral hose for oils, water, food, and compressed air. 

EPDM is the fourth highest volume general purpose elastomer used today in the ruhher industry. At 2.7 hillion pounds of global annual production in 2010, EPDM represents about 10% of the total synthetic rubber production. However, unlike NR, SBR, and BR, this synthetic rubber is mostly used in the nontire sector (only a small amount of EPDM may be used in tire white sidewall compound, cover strip, and bicycle tires). EPDM is commonly used in single-ply roofing, in automotive weatherstrips, and hundreds of other applications. 

The effect of graphite on the coefficient of frietion depends to a great extent on the graphite s purity. Graphite grades which were found suitable for low friction automotive weatherstripping had a carbon concentration above 95% (inferior... 

It is eustomary for automotive weatherstripping to be coated with silieone or urethane spray to impart a low coefficient of fiiction surface for easy door elosure and freeze release. This is to prevent automobile doors and trunk lids from freezing shut at low temperatures. ... 

A comparative analysis of TPV vs. EPDM with respect to noise reduetion is examined for automotive weatherstrip body sealing apphcations. Specifically, EPDM sponge is eonqjared with JyFlex , a TPV compound of equivalent stiflhess. The study is performed using multiple acoustic tests (road and component), supported by FEA analysis as a diagnostic tool [1],... 

Bayer, USI, and DuPont are U.S. suppHers. There is an estimated 2300—4000 t/yr of EVA used in the United States. Uses include automotive electrical system components, eg, ignition cable, footwear, weatherstripping, and misceUaneous O-rings and seals for industrial appHcations. 

NitrinexEPDM. [A.Schulman] EPDM for wire and cable insulation, automotive parts, hoses, seals, extruded and mold goods, weatherstripping. 

The applications are automotive window seals and fiiel filler gaskets, industrial door and window seals and weatherstripping, wire/cable covering, and hand-held power tool housing/handles. Nonslip soft-touch hand-held tool handles provide weather and chemical resistance and vibration absorption.i Translucent grade is extruded into films for face masks and tube/hosing and injection-molded into flexible keypads for computers and telephones. Certain grades are paintable without a primer. Typical durometer hardnesses are Shore A 60, 76, and 80. 

The automotive industry usually eites technieal shortcomings rather than health eonsiderations for attempting to reduce its dependence on PVC in vehiele eomponents. Flexible PVC has been used in the past in underseal, instrument panels, wiring insulation, weatherstrip, window sealants, body side protection strips, door panels, seats, armrests and sun visors. Many of these applications require a soft, flexible material that used to be diffieult to produce without PVC, but can now be made using a modified polyolefin formulation. 

The main uses of EPM and EPDM are in automotive applications as weatherstrip profiles, automotive coolant hoses, air-conditioning and brake hoses, and seals. In building and construction EPDM is used in sealing profiles, roofing foil, and seals in cable and wire as cable insulation and jacketing and in appliances in a wide variety of mostly molded articles. 

Automotive manufacturers continue to demand improvements in the colour stability of their weatherstripping. The iridescence sheen phenomenon occurs particularly in EPDM when the fabricated articles are exposed to UV light and ozone. Recently a unique new filler called Neuburg siliceous earth has arrived in the North American marketplace from Europe. This study compares the influence of these unique fillers with those presently used in North America. This study will also... 

Rubber weatherstripping for automotive exteriors is usually produced from compounds based on EPDM. These weatherstrips can be dense (no voids), cellular (closed cell structure), or semidense. Weatherstripping is commonly extruded and cured in a continuous vulcanization unit (CVU). Some new production lines are switching over to thermopiastic elastomers (TPEs), which eliminate the curing step, with a reduction in production costs. 

In the automotive market, cyanoacrylates are used to bond weatherstripping to automotive bodies and to position rubber gaskets before assembly. They are used to bond polycarbonate positioning clips to side windows of automobiles, alternator horn assembly components, and rubber gaskets to automotive thermostats. One of the most common automotive applications is the use of cyanoacrylates in the repair of flexible PVC side trim strips. 

Solvent cements of the neoprene or SBR type are used in automotive interiors to fasten roof linings, sound deadener pads, and rubber weatherstripping to doors or door openings. Hot melts of the polyamide type are used as carpet-to-floor adhesives and to anchor instrument gauge springs.
