Thermoplastic pvc hose for severe cold service

A hose comprising:

• at least one tubular layer formed from a polyvinyl chloride (PVC) composition comprising:
• a) one or more base polymer(s) present in a total amount of 100 phr, the base polymer(s) including one or more PVC polymer(s), the PVC polymer(s) being present in a total amount of at least 70 phr;
• b) one or more adipate plasticizer(s) present in a total amount from 50 phr to 85 phr, the adipate plasticizer(s) including one or more dioctyl adipate (DOA) plasticizer(s), the DOA plasticizer(s) constituting a majority by weight of the adipate plasticizer(s);
• and
• c) one or more non-adipate plasticizer(s) in a total amount from 0 phr to 30 phr;
• wherein a total plasticizer content of the PVC composition, including (b) the adipate plasticizer(s) and (c) the non-adipate plasticizer(s) when present, is in a range from 70 phr to 110 phr;
• wherein a total phr of the PVC composition, including (a) the base polymer(s), (b) the adipate plasticizer(s), and (c) the non-adipate plasticizer(s) when present, is from 170 phr to 210 phr;
• wherein the PVC composition does not contain more than 20 phr of one or more other ingredient(s) in total combination, the other ingredient(s), when present, excluding (a) the base polymer(s), (b) the adipate plasticizer(s), and (c) the non-adipate plasticizer(s);
• and
• wherein the PVC composition exhibits cold-temperature embrittlement resistance by not cracking when bent at temperatures of at least −65 F or colder as tested in accordance with ASTM D380.
