METHOD FOR PRODUCING A MOLDING COMPOUND
A method for producing molding compounds, at least including a binder and a softener, the binder and the softener being in the form of plastisols, the plastisol being essentially composed of PVC and softener, the method of production has the following steps: in a first step, mixing the PVC powder and the amount of softener with optionally other admixtures and/or additives and carrying out the mixing process at a mixing temperature of approximately 55 to 70° C.
1 - 6 . (canceled)
7 . A method for producing a molding compound, including at least a binder and a plasticizer, the binder and the plasticizer being in the form of a plastisol, the plastisol being composed substantially of PVC and plasticizer, the method comprising the steps of: subjecting a PVC powder and an amount of plasticizer with any other supplements and/or additives to a mixing process at a mixing temperature of 55 to 70° C.
8 . The method according to claim 7 , wherein a plasticizer content is between 32 and 60% by weight.
9 . The method according to claim 8 , wherein the plasticizer content is between 35 and 55% by weight.
10 . The method according to claim 9 , wherein the plasticizer content is between 38 and 53% by weight.
11 . The method according to claim 7 , wherein the plasticizer is formed as a phthalate-free or a phthalate-containing plasticizer.
12 . The method according to claim 11 , wherein the phthalate-free plasticizer is based on citric acid, adipic acid and/or benzoate ester.
13 . The method according to claim 11 , wherein the phthalate-free plasticizer is acetyl tributyl citrate, tri(2-ethylhexyl) acetyl citrate, trioctyl citrate, tridecyl citrate, tributyl citrate, trihexyl citrate, triethyl citrate, dioctyl adipate, diisodecyl adipate, diisononyl adipate, diisononyl 1,2-cyclohexanedicarboxylate, acetic acid ester of monoglycerides, benzoates or a mixture of at least two of said substances.
14 . The method according to claim 7 , wherein the molding compound is composed of at least
20-68% by weight binder
32-60% by weight plasticizer
0-40% by weight filler
0-20% by weight other additives.
