Skim Block Visually Graded Rubber
Skim Block Rubber is a distinctive rubber product, produced through a specialized process involving coagulated latex and various forms of field coagulum such as tree lace, shell scrap, and earth scrap. This process includes multiple passes through heavy rolls known as crepers, followed by air-drying at ambient temperatures. The result is a crinkly lace rubber characterized by its rapid-curing and granulated nature.
Differing from other rubber types, Skim Block Rubber has a notable higher proportion of non-rubber substances. This characteristic not only defines its unique composition but also its range of applications. As a by-product of the latex centrifuging process, it contributes to more sustainable rubber production practices by utilizing materials that would otherwise go to waste.
Features of Skim Block Rubber:
- Sustainable Production: Utilizes by-products of latex processing, reducing waste and promoting environmental sustainability.
- Unique Composition: Contains a higher proportion of non-rubber substances compared to conventional rubber types.
- Versatile Use: Its composition allows for a wide range of applications across different industries.
Applications of Skim Block Rubber:
Skim Block Rubber is used in various applications, leveraging its unique properties for different industrial needs:
- Conveyor Belts and Mats: Suitable for creating durable industrial conveyor belts and mats.
- Rubber Products: Its flexibility and composition make it a suitable material for a variety of rubber products including rubber bands and car mats.
- Shoe Soles: Can be used as a filler in the production of shoe soles, offering durability.
Skim Block Rubber offers a practical solution for manufacturers looking for a versatile and sustainable rubber material. Its unique production process and composition allow it to serve a wide array of applications.
