SILICONE RUBBER OIL HOSE DEVELOPMENT

Oil transfer hoses made of silicone rubber have been developed for automobile and truck engine use. Four basic compounding approaches are: filling a general-purpose base with high levels of inexpensive filler; blending two general-purpose stocks to give desired durometer; selecting a stock especially developed for hose fabrication; and modifying a high-performance stock to improve oil resistance. Fabrication is either by hand layup or continuous extrusion. Some tradeoffs in formulations and fabrication methods include improved tensile and tear strength at higher cost, and hand layup vs. extrusion, the former giving good bursting strength at a cost penalty. The service life of a hand-fabricated hose is dependent on the liner stock and the fabric reinforcement. Laboratory test results on hand-fabricated hose indicate a greatly extended service life for the four formulations over that of organic rubber formulations. The extruded oil transfer line has not been sufficiently tested to draw any conclusions on its service life.
