Summary
Yellowing on EPDM rubber surfaces is often caused by MDI polyurethane binders under sunlight. FieldsMaster offers two solutions: 21 EPDM granule colors for MDI binders and the yellowing-resistant FM 1185 aliphatic binder. These ensure vibrant, long-lasting colors for any climate.

· How the Yellowing Issue Happens to EPDM Rubber Surface
In the past 28 years of production process of FieldsMaster, we have continuously investigated the feedback of market users ,customers and partners, and continuously conducted research and discussions with our dealers.
In the communication with customers from all over the world, we also found that many customers cannot distinguish the "yellowing" and "fading" problems of the EPDM field very well. When problems occur in EPDM rubber fields, customers have not found the correct solution and cannot bring users a good sports experience, which in turn affects the market development of customers.
There are two main color problems of EPDM rubber fields. One is yellowing and the other is fading. In this blog we mainly discuss on Yellowing Issue.
Simply put, the main reason for the EPDM rubber field yellowing problem is polyurethane binder. There are two main types of binder used for the construction of EPDM rubber granules, one is aromatic binder, commonly known as MDI binder, and the other is aliphatic binder. MDI binder is quite popular in the market because of its price advantage. However, due to its special chemical performance, MDI binder will turn yellow under sunlight. However, the color of the EPDM surface where aliphatic binder has been applied will not turn yellow. In short, the color of the EPDM rubber granules is almost the same as the color of the rubber surface after application.
· How FieldsMaster Resolve Yellowing Issue on EPDM Rubber Surface
FieldsMaster currently has three self-invested automated factories, mainly producing colored EPDM rubber granules, and also has invested production line for producing polyurethane binder. Our product development team has conducted continuous exchanges and learning with well-known companies such as DOW and BASF, and has continuously adjusted and upgraded the product formula of polyurethane glue based on market feedback to meet the needs of market users in various climate conditions around the world.
Our FM-PU 8004 is a classic MDI glue. Over the years, we have continuously improved the formula based on continuous market feedback. It has good strength and hardness, and can resist wear and corrosion. Because the color of the EPDM granules after the construction of MDI binder will immediately turn yellow and the color will deepen, some customers will mind this color difference problem. For this reason, we have launched 21 colors of EPDM granules, which are suitable for site construction with our FM 8004 aromatic binder, which can well prevent the problem of serious color difference after the site construction is completed
Another type, FM-PU 1185 is Aliphatic binder, which has good yellowing resistance. Customers can freely choose the 62 color cards we mainly promote. After the construction of the site is completed, the site will not have a large color difference even under strong sunlight. Now FM 1185 has been widely applied in markets and proves to be a good choice for anti-yellowing.
FieldsMaster is well aware that the color of the site is extremely important to our partners. In China, we have cooperated with the top- 50 real estate companies. FieldsMaster's EPDM colored granules and polyurethane binder have been laid in nearly 8,000 residential areas. Most of these sites are on the ground of children's playgrounds and are built for children. Therefore, most of our real estate customers' site designers like to choose bright colors to design imaginative site patterns to bring more joyful experience to children's sports.
