ABSTRACT:
Flexible PVC hose can be used with toilet systems in vehicles, such as boats, recreational vehicles, etc, or at pumpout stations. The hose includes about 40-55% by weight PVC resin, and at least 10% by weight of an EVA high molecular weight plasticizer. The hose also typically includes a low molecular weight plasticizer, stabilizer, lubricant, filler (such as 5-20% by weight dense filler like calcium carbonate), and pigment. The hose typically will not fail (that is will not transmit odor) for the life of the toilet system, or mechanical life of the hose.
