Now in order to reduce production costs, many shoe material manufacturers have begun to use recycled rubber in the rubber soles, and some of the high-grade rubber soles usually use latex reclaimed rubber. In actual production, the latex reclaimed rubber used is different because of the performance requirements and appearance requirements of the rubber sole. Then, when the shoe factory chooses latex reclaimed rubber, what aspects do you need to start? How can I choose the right latex reclaimed rubber?
First of all, we should make it clear that latex reclaimed rubber, which is made from waste natural rubber, waste natural rubber products and waste latex products, is the most elastic variety. It is mostly used in rubber soles with natural rubber as the main raw material. The sole has high comfort and softness, and it is best to use latex reclaimed rubber for sports soles.
Latex reclaimed rubber is mostly white latex reclaimed rubber and black latex reclaimed rubber, plus a small amount of colored latex reclaimed rubber such as red latex reclaimed rubber, blue-green latex reclaimed rubber (very few on the market), generally light color, white sports soles White latex reclaimed rubber, color rubber soles also use white latex reclaimed rubber, one is easy to match color in the production process, and secondly, there are too few latex reclaimed rubbers on the market. Some black rubber soles can be directly used with black latex reclaimed rubber, which is more cost-effective and does not have to worry about “fading”.
Secondly, according to the tensile strength and elongation of the rubber sole, the latex reclaimed rubber with the closest index can be selected, so that the quality of the rubber sole can be ensured to the greatest extent and the raw material cost can be reduced. Generally, the latex rubber having higher rubber content has higher tensile strength, higher elongation at break, and better elasticity.
Latex reclaimed rubber is used in sports soles and sponge midsole. In addition to considering the color and various indicators of latex reclaimed rubber, shoe manufacturers also need to consider the shipping cost of recycled plastics to be purchased. Generally, latex reclaimed rubber with low gel content is best purchased nearby because of low gel content. Latex reclaimed rubber is filled with calcium carbonate, and we don't have to pay high shipping costs for cheap light calcium.
The quality stability of latex reclaimed rubber products is also an important consideration for shoe manufacturers. The quality stability is directly related to the quality stability of rubber soles. The production scale and inventory of reclaimed rubber plants determine whether the sole manufacturers can follow the production plan. normal production. Therefore, when choosing a latex reclaimed rubber, the shoe factory needs to select a good partner, and choose a reclaimed rubber factory with a certain scale and a registered trademark to ensure that the rubber sole will not be affected by the quality fluctuation of the latex reclaimed rubber, and the latex reclaimed rubber is out of stock. Out of stock brings unnecessary trouble to sales and production.
