 process with a typical production lead time in the range of 24 hours, meaning that industrial mass production requires comprehensive machinery.
To alleviate or avoid these disadvantages a number of propositions have been made relating to the production of uridoms and similar products using different materials and methods.
The Danish patent application No.1549/79 thus discloses a method for manufacturing prophylactic devices such as condoms and fingerstalls by thermomoulding, whereby an extruded piece of a film of a thermoplastic polyurethane elastomer is deformed by means of a mandrel. The method thus requires a preprocessing of the PUR material into film and a subsequent extrusion into small units which in the moulding process are heated to a temperature high enough to soften the material.
Applying this method it is difficult to obtain the thin wall thickness, 150-200 u, which is required of a uridom and, added to this, polyurethane does not have sufficiently good elastic properties to be a user-friendly alternative to the conventional latex uridoms, inasmuch as a polyurethane product will be perceived as tight.
In addition, base materials which are based on polyurethanes contain substances that are detrimental to the environment, such as, e.g. isocyanate.
U.S. Pat. No. 4,817,593 discloses a method for manufacturing condoms by which a mandrel is dipped into a polyurethane solution in an organic solution and is cured at a high temperature. Contrary to the latex technology the mandrel is dipped into the solution only once, but the method does not remedy the above-mentioned deficiencies in using polyurethane as base material.
U.S. Pat. No. 4,808,174 discloses a method for manufacturing condoms of plastics such as polyethylene, polypropylene or vinyl. The method is identical to the one described in the above-mentioned Danish patent application, i.e. preprecessed films are heated to a temperature which is high enough to soften them and are then moulded on a mandrel.
The Danish publication No.137 243 describes a method for manufacturing rubber products by repeated dipping into an elastomer solution consisting of a SBS or SIS block copolymer strained with 5-100 percentage by weight of a mainly naphtenic/aromatic petroleum oil and dissolved in 200/1200 percentage by weight of an aliphatic hydrocarbon, preferably petrol. The method first and foremost implies an environmental hazard, because comparably large quantities of solvents are employed and, furthermore, the
process with a typical production lead meter in the compass of 24 hours, meaning that industrial mass output requires comprehensive machinery. 
 To alleviate or debar these disadvantages a number of proposition have been made relating to the output of uridoms and similar products use unlike materials and methods. 
 The Danish patent lotion No.1549/79 thus unwrap a method acting for manufacturing prophylactic devices such as condom and fingerstalls by thermomoulding, whereby an extruded piece of a film of a thermoplastic polyurethane elastomer is deformed by means of a spindle. The method therefore requires a preprocessing of the PUR material into film and a subsequent extrusion into little units which in the moulding process are heated to a temperature high enough to cushion the material. 
 Applying this method it is difficult to obtain the thin wall thickness, 150 - 200 u, which is required of a uridom and, added to this, polyurethane does not suffer sufficiently good elastic properties to be a drug user - friendly option to the ceremonious latex uridoms, inasmuch as a polyurethane product will be perceived as tight. 
 In addition, base materials which are based on polyurethanes control substances that are detrimental to the environment, such as, e.g. isocyanate. 
 U.S. Pat. No. 4,817,593 discloses a method for fabrication condoms by which a mandrel is dipped into a polyurethane solution in an organic solution and is cured at a high temperature. Contrary to the latex paint engineering the spindle is dipped into the solution only once, but the method does not remedy the above - mentioned deficiencies in using polyurethane as base fabric.
