The low air permeability material compounds were developed in the area of tire inner liner rubber. Butyl rubber compounds, which contain special resin or plate crystal-structure filler could improve barrier properties. Using this rubber compounds, tire inner liner thickness decreased by 40%. As a result, tire weight and tire rolling resistance are reduced.

In order to respond to the increasing global environmental regulations, we are continuously carrying out tire lightening research. Studies conducted to make the thickness of under-tread thin. And the performance of the tread adhesion test method was verified in response to the thickness thinning. As a result of comparing the thinning effect of the cap tread and the under tread under the same weight condition among the tread regions, it was confirmed that thinning the under tread was effective in improving rolling resistance and braking distance compared to the cap tread. Based on this study, it was confirmed that rolling resistance can be improved without loss of driving performance.

A wheather strip is a sponge form rubber by a forming agent, which prevents the penetration of water and dust, also reduces wind-noise and vehicle-vibration while driving. Recent, an investigation of abrasion resistance reinforced coating is demanded, due to an occurrence of a problem, which is a tearing and wearing of body-side weather strip. So, a development of a new wheather strip coating is promoted. As a result, an abrasion resistance reinforced coating is developed and applied to automobiles, which coating shows 10 times improved abrasion resistance performance, in comparison with current wheather strip coating.

Oil resistance of EPDM (Ethylene Propylene Diene Monomer), a rubber material for general purpose in automobile industry; is developed by high loading of carbon black. This paper describes improving procedures for compounding the EPDM rubber for air intake hose. Through the testing of material, part, and vehicle test, low oil swell EPDM for air intake hose is fully verified.
