How can rubber products prevent fading?

Answer:

Light and white rubber products are prone to yellowing in the course of use and storage, thus affecting appearance and quality, resulting in various economic disputes and irreversible losses.
That is to add UV absorbers, white, then add more titanium dioxide, there is no good way, as well as your choice of pigment, as far as possible difficult to fade, such as inorganic pigments.
For example, footwear product quality inspection process found in the yellowing resistance of some poor performance materials, shallow white soles during the experiment; and meet many enterprises in the production of light, white shoe sole in the process of use and storage in color yellowing phenomenon; even found some enterprises in the production of light, white sole test HG/T3689-2001 "footwear yellowing resistance test method" to determine the material in the approximation of the sun light, ultraviolet radiation resistance to yellowing ability, the observed color change of sample surface degree of occurrence is not large, but the sole is made into shoes in the process of use and storage is prone to yellow phenomenon.
