Slipper white marks:
The problem of slipper white marks usually refers to the uneven color, spots, or patches that appear during the production or use of slippers. This situation may be caused by various factors, including material quality, production process, usage environment, etc.
The following is a detailed analysis of the problem of slipper white marks:
1.Why there are slipper white marks:
Material quality:
The raw materials of slippers, especially EVA (ethylene vinyl acetate copolymer) and other materials, if the quality is unstable or contains impurities, it is easy to cause white spots. During the production process of EVA materials, if different batches or properties of raw materials are mixed in, uneven color may occur.
Production process:
Improper control of parameters such as temperature, pressure, and time in the production process may also lead to slipper white marks. For example, uneven mold temperature and unstable injection pressure during the injection molding process may affect the molding quality of slippers.
Usage environment:
During the use of slippers, prolonged exposure to sunlight, moisture, or chemical substances may also cause color fading or spot formation.
2.How to solve slipper white marks:
Choosing high-quality materials:
Choosing raw materials with stable quality and low impurities is the key to avoiding slipper spots. Manufacturers should strictly control the quality of raw materials to ensure that each batch of raw materials meets production requirements.
Optimize production process:
By optimizing the production process, such as adjusting injection molding temperature, pressure, and time parameters, ensure that slippers can be uniformly heated and pressure distributed during the molding process, thereby reducing the occurrence of slipper white marks.
Adding additives:
For the problem of white spots in EVA slippers and other products, specialized additives can be added to improve it. Xiangxi silicone masterbatch,DX518 is a product specifically developed for addressing the issue of white spots in EVA products, which can significantly improve the phenomenon of white spots and enhance the surface glossiness of the product.

Improving the usage environment:
When using slippers, it is advisable to avoid prolonged exposure to sunlight, moisture, or chemicals to minimize the impact on the color of the slippers.
3. Market situation:
At present, there are various styles and materials of slippers on the market, among which EVA slippers are widely popular due to their lightweight, soft, and wear-resistant characteristics. However, with the increasing demand of consumers for product quality, issues such as slipper spots have gradually attracted attention. In order to meet market demand, some manufacturers have begun to develop and promote products and technologies that can effectively solve the problem of slipper white marks.
The issue of slipper white marks are complex problems involving multiple aspects such as materials, craftsmanship, and usage environment. By selecting high-quality materials, optimizing production processes, adding additives, and improving the usage environment, the occurrence of slipper spots can be effectively reduced and product quality can be improved.
