Abstract
A plasticized thermoplastic PVC compound used for manufacturing at least one layer of a flexible or spiraled hose for transporting fluids includes (A) a suspended PVC matrix having (A1) 20-40% by weight of PVC with a K factor measured according to the DIN EN ISO 1628-2 standard greater than 95, and (A2) 20-40% by weight of PVC with a K factor measured according to the DIN EN ISO 1628-2 standard between 65 and 80; (B) 18%-45% by weight of at least one plasticizing agent; (C) 0.5-1% by weight of at least one stabilizing agent; (D) 1.5-4% by weight of at least one co-stabilizing agent; and (E) 0-10% by weight of at least one additive.

A method of manufacturing a hose, comprising:
- extruding the hose to have a first layer,
- wherein the first layer is made from a plasticized thermoplastic PVC compound comprising:
- (A) a suspended PVC matrix comprising:
- (A1) 20-40% by weight of a PVC having a K factor greater than 95 when measured according to DIN EN ISO 1628-2;
- and
- (A2) 20-40% by weight of the PVC having the K factor comprised between 65 and 80 when measured according to the DIN EN ISO 1628-2 standard;
- (B) 18%-45% by weight of at least one plasticizing agent;
- (C) 0.5%-1% by weight of at least one stabilizing agent;
- (D) 1.5%-4% by weight of at least one co-stabilizing agent;
- and
- (E) 0%-10% by weight of at least one additive;
- wherein weight percentages of components (A)-(E) are calculated with respect to a total weight of the plasticized thermoplastic PVC compound, and
- wherein a sum of the components (A)-(E) is 100%.
A flexible hose comprising:
- a first layer;
- and
- a second layer,
- wherein the first layer is made from a plasticized thermoplastic PVC compound comprising:
- (A) a suspended PVC matrix comprising:
- (A1) 20-40% by weight of a PVC having a K factor greater than 95 when measured according to DIN EN ISO 1628-2;
- and
- (A2) 20-40% by weight of the PVC having the K factor comprised between 65 and 80 when measured according to the DIN EN ISO 1628-2 standard;
- (B) 18%-45% by weight of at least one plasticizing agent;
- (C) 0.5%-1% by weight of at least one stabilizing agent;
- (D) 1.5%-4% by weight of at least one co-stabilizing agent;
- and
- (E) 0%-10% by weight of at least one additive;
- wherein weight percentages of components (A)-(E) are calculated with respect to a total weight of the plasticized thermoplastic PVC compound, and
- wherein a sum of the components (A)-(E) is 100%.
A spiraled hose comprising:
- a main body having at least one layer made from a plasticized thermoplastic PVC compound that comprises:
- (A) a suspended PVC matrix comprising:
- (A1) 20-40% by weight of a PVC having a K factor greater than 95 when measured according to DIN EN ISO 1628-2;
- and
- (A2) 20-40% by weight of the PVC having the K factor comprised between 65 and 80 when measured according to the DIN EN ISO 1628-2 standard;
- (B) 18%-45% by weight of at least one plasticizing agent;
- (C) 0.5%-1% by weight of at least one stabilizing agent;
- (D) 1.5%-4% by weight of at least one co-stabilizing agent;
- and
- (E) 0%-10% by weight of at least one additive;
- wherein weight percentages of components (A)-(E) are calculated with respect to a total weight of the plasticized thermoplastic PVC compound, and
- wherein a sum of the components (A)-(E) is 100%;
- and
- at least one reinforcement spiral embedded in the main body.
