Case study: "I want to create a completely white baseball base! Rubber products are not just 'black'! We have published solutions to problems such as difficulty in coloring and discoloration!"

信栄ゴム工業

When it comes to rubber products, the image of "black" is quite strong. This is because carbon black, a "black" reinforcing agent, is added to the rubber, making it "black." This carbon black is a very important chemical for strengthening the rubber. However, we often receive inquiries about wanting to color the rubber in various colors such as "white" or "red." One representative example is a baseball "base." The baseball base is "pure white." We use rubber materials that are "pure white." If dust or the commonly used "black" carbon black gets mixed into the materials during the mixing stage, or if it adheres to the materials after mixing, the color of the materials can change instantly. Even during the molding stage, the color of the product can change due to dust or dirt on the mold. Additionally, if the product gets sunburned after molding, it can turn brown, so caution is necessary. *For more details, please download the case study from the link below or contact us.*
