Raw materials:
Belt: Japanese neoprene (CR) or hydrogenated nitride rubber (HNBR) as the main raw materials
Skeleton materials: Japanese glass fiber cord
Belt tooth: nylon 66 for protection
Clean, full profile, long life span, low noise characteristics
Characteristics of automotive timing belt:
CR belt:
heat is good can be at 120 ° c and below, working environment and long-term use
Anti-aging is good especially ozone-resistant properties must gifted
Good chemical stability: in addition to strong oxidizing acid, the chemical resistance of the general erosion
Great fire, water-resistant properties
HNBR belt:
Oil resistance excellent oil resistance with very low inflation, higher oil resistance
Durability good dynamic performance than chloroprene rubber belt for the gifted, first choice in the luxury car drive belt
Wear properties gifted wear than small chloroprene rubber belt to reduce the noise, effectively extending the life span of the belt

HNBR automotive timing belt in the applications:
Hyundai motor because of energy-saving, environmental protection, comfort and security requirements increasing, making the whole engine room structure complex, compact, high working temperature, rubber pieces which should have high temperatures performance
Improved engine lubrication technology, lubricants used in a new additive, in engine oil resistance of the rubber pieces to higher demand
Other hand, long maintenance period, durability of rubber pieces there are increasingly high requirements
Hyundai motor rubber pieces require oil resistance in certain conditions in the -40 to +150°C transmission belt is the important automotive rubber parts, including OHC engine when used with the regulation that is synchronous belt, automotive auxiliary drive V-belt use in cars and multiple wedge zone and the newly developed CVT institutions (CTV) by the variable V-belt
Since 1975 HNBR announcement of the first patents, HNBR is becoming today's world car production preferred standard synchronous belt elastomeric material
Modern cars on the synchronous belt specific requirements:
Durability increase 1.5 times higher than the bandwidth reduced 20%, increased 10°C heat
Synchronous belt by the rubber and fiber tensile body (fiberglass or kevlar) and composed of nylon cloth tooth complex
HNBR manufactured synchronous belt whether fatigue life
