Latex reclaimed rubber elasticity, elongation at break, is widely used in the production of various types of sports soles, both to ensure the flexibility and comfort soles, but also reduce the cost of raw materials, the largest amount of white latex reclaimed rubber. This is because the white latex reclaimed rubber has white color, easy color matching and can be used to produce all kinds of white, light-colored and colored sports soles. However, there are times when discoloration occurs in sports soles produced from white latex reclaimed rubber, mainly yellowing and turning blue. Why?
1, white sports shoes yellowing: general white sports shoes parked yellowing problems, usually the use of rubber in the production process improper use, or the quality of rubber oil, however, the phenomenon of migration, or the excessive use of rubber oil led to Spurt.
2, white sports soles pan-blue: In order to increase the viscosity of latex reclaimed rubber, plastic processing to improve performance, improve product brightness and elongation at break, the production of sports soles often add a certain percentage of rosin. Rosin, however, is an unsaturated acid that absorbs UV light and then oxidizes in the air or is induced to oxidize, causing the panning of white rubber sole surfaces.
Whether it is yellowing, or pan-blue, will affect the beauty of sports shoes, rubber products soles in the production of sports soles must pay attention: Do not save a little money to buy low-grade chemical additives, such as rubber oil, Carbon black, poor quality accessories will lead to rubber products produced from reclaimed rubber instability, resulting in discoloration and migration, resulting in a series of problems, it is worth the candle.
Use latex reclaimed rubber to produce sports soles. When choosing latex reclaimed rubber, be sure to choose not to relocate the latex reclaimed rubber, and carefully select cooperative manufacturers. If there is a migration phenomenon in the reclaimed rubber itself, the resulting rubber soles will experience migration. The rubber sole produced from high-quality latex reclaimed rubber has good elasticity, flexibility and flexibility. Substituting natural rubber can significantly reduce the cost of raw materials.
