hese components, manufactured by our company, are very important constituents of the sealing system of an automobile. The wear and tear that these components go through due to the nature of their application has meant that they are manufactured in high-end EPDM compositions. The components have to ensure perfect sealing from the external environment without compromising on the cushioning required during the operation of the doors. Thus the factors like sponge levels, relaxed modulus, compression set, ageing properties and other related parameters have to be delicately balanced and stringently monitored to provide optimal product characteristics.
