RUBBER MATERIAL, SEAL COMPONENT AND HOSE

摘要

PROBLEM TO BE SOLVED: To increase the acoustic insulation of a rubber material without deteriorating its physical properties and increasing its weight.SOLUTION: Provided is a rubber material obtained by blending a rubber polymer with low molecular weight hydrocarbon based oil with a weight average molecular weight of 1,500 or lower and high polymer hydrocarbon based oil with a weight average molecular weight of 5,000 or higher. The high molecular weight hydrocarbon based oil is preferably blended by 10 to 90 mass% to the total oil content in the rubber material. A weather strip 1 and a hose 2 are formed by the rubber material.
