changing the general performance characteristics of those rubbers for example hevea rubber made for use as a textile elastomer as used in bungee cords waistbands suspenders and hundreds of other products in this case 34 gauge rubber thread which has a useful life expectancy of approximately 2 years according to the manufacturer was treated with this invention with dye included the result was a dyed rubber which retained its original performance characteristics stretch recovery modulus etc and would be as useful today in standard applications as during its intended lifespan this sample was treated fifteen 15 years ago this indicates that a certain aspect of longevity of usefulness has been introduced by this invention what the inventor calls u201c fortification u201d which is distinct from other processes such as vulcanization coloration and fortification of rubber may also be achieved prior to product forming if the user includes this invention with colorants dyes and pigments in the solid or liquid states of rubber prior to product formation this invention may also be used to color carbon black before it is included in the compound mix ensuring a better u201c jetness u201d to the black through the entire body of the finished product other methods are used to color carbon black but they are by their own description u201c paints u201d this invention introduces a penetration dye or pigment coloring the alternative methods are recommended for use on rubber products where there is no need for retention of performance characteristics such as in tires recycled for use as playground and road surfaces in some cases for example but not limited to when the flash point of the formulation is of concern to the end.
