Polaris Oil Reservoir   Industry Other Industries Material Stanyl® TW200F3 - PA46-GF15   Processing Technology Injection Molding Description Polaris Industries' ATVs have been delivering adventure and reliable performance for years. Used for farming, ranching, hunting, and recreation the automotive components in these 4X4 machines must withstand high operating temperatures. One component in particular that must meet harsh operating conditions is the oil storage compartment. Metal can meet all requirements for this part, but at a high cost compared to plastic. The 2002 Polaris Sportsman 400 and 500 model ATVs have been produced using new Stanyl® oil reservoirs. The Sportsman 400 and 500 models are dry-sump engine designs which do not have an internal oil reservoir within the crankcase, thus requiring an external reservoir. Polaris designed a new oil reservoir to replace the die-cast aluminum reservoir that was similar in shape and mounted to the exterior of the vehicle. It was imperative that the reservoir withstand exposure to oil that reaches 300ºF, while maintaining stiffness and providing impact resistance. Stanyl® delivers on these demands providing better impact and stiffness over other thermoplastic materials at high temperatures and better property retention after 5,000 hours of exposure to hot oil and thermal cycling. Replacing the die cast aluminum with Stanyl® resulted in a cost reduction and a 51% weight reduction as well as a better performance to cost ratio in hot oil applications over its competitors. When harsh operating conditions are to be met and sports performance is an issue, Stanyl® is the material solution to replace expensive metal parts. OEM Polaris
