A rubber and plastics product Co., Ltd. in Foshan, Guangdong Province, in the expansion of business scope, research and development of production of white foam rubber soles, there is a problem: white rubber soles after the production line appeared after the yellowing migration, although not affect the use of performance, but the impact of beautiful After repeated inspections by the technical team, the white rubber sole formula being developed has no problem with accelerators, vulcanizing agents, rubber oils, etc. Therefore, it is impossible to find a reason. New product development plans can only be temporarily suspended.
Later, when engineers searched the Internet for yellowing solutions for rubber products, they accidentally saw the technical personnel of Hongyun’s view of the migration of rubber products and placed white foam rubber soles that had just been sampled in white plastic bags. A small test found that both the surface of the rubber sole and the packaging bag appeared yellowed, and as the technicians of Hongyun said, it is very likely that the rubber oil itself has a migration phenomenon and decided to change the oil, and then gave us Hongyun Sales Headquarters made a phone call and expressed the hope that it would send samples of Tar oils in the past.
Hongyun's environmental protection tar oil is an environmentally-friendly plant rubber oil produced from the pine nodules in Russia's alpine regions and produced through a complex process such as distillation. Its main components are fatty acids and rosin acids, and its emulsification rate is comparable to ordinary rubber oils. Faster, better disperse, no migration, more plasticizing effect. For this manufacturer, environmental protection and no migration are the most concerned. After testing, the yellow rubber phenomenon was solved after replacing the rubber oil in the original white rubber sole's original formula with Hongyun Environmental's Tar oil.
In the following contact, the manufacturer’s engineers sighed: Well, I was actually drawing a circle for myself, and I kept circling around in the circle. I just couldn't get out of it. I didn’t expect to lose to these 5 rubber oils. . When adjusting the white foam rubber sole formula, the accelerator, vulcanizing agent dosage and variety were all taken in account. The amount of rubber oil was also taken in consideration. The sole proprietor did not think of the problem of the rubber oil type, if not on the Internet, he saw the regenerative rubber. Maybe I'm still in circles?
Case Summary: There are many reasons that cause rubber products to undergo discoloration and migration. One of the causes of the yellowing of the surface of rubber products is the rubber oil problem, or the excessive use of rubber oil causes the surface of the rubber product to bloom, or the rubber used in the formulation. There is a migration phenomenon of oil itself, and this is irreparable in the later period; therefore, rubber product manufacturers must consider the quality of their products and the phenomenon of migration when they choose to soften the rubber products, especially light-colored and colored rubber products. Production.
