PU Binder Manufacturer In India

Since its invention, polyurethane has been one of the most important compounds, with numerous applications. A leading participant in coating and printing applications, polyurethane is known for its flexibility, strong chemical structure, and user-friendly qualities.

Topfloors Sports Infra is a PU Binder Manufacturer in India and our one-component, moisture-curing, unpigmented PU binders are DESMOTOP-RR 2009 and DESMOTOP-RR 2008. Timber, polystyrene foam, plastic, urethane foam, reclaimed rubber, gravel, cloth, metal surfaces, and many more substrates can be bonded with these. Substrate, ambient temperature and relative humidity determine the PU binder cure rate. Using a hot press on PU binder can drastically shorten the curing period.

One form of adhesive or bonding agent made with polyurethane resins is a polyurethane (PU) binder for rubber. Rubber mats, playground floors, and athletic tracks are just a few examples of the many goods that bind rubber particles together.

Rubber goods are made better in terms of strength, flexibility, and longevity when PU binders are used. They make the rubber particles stick together well, making the substance strong and durable. As a result, rubber-based treatments work better and last longer.

When compared to other binding materials, PU binders are far superior in terms of bonding strength, durability, flexibility, and resistance to weather. Their versatility stems from the fact that they help rubber products remain stable and long-lasting in general.

Certainly, PU binders can withstand the elements. Outdoor rubber products, such as playgrounds, sports surfaces, and running tracks, benefit greatly from their high resistance to weathering, temperature fluctuations, and ultraviolet radiation.

One common method of applying PU binders is to combine them with rubber particles. The resulting slurry is then either poured or smeared onto a surface. After the binder cures, the mixture is balanced, and the result is a rubberized substance that is both strong and flexible.

When it comes to recycling rubber, PU binders are an important component. One way they can help with sustainability and trash reduction is by binding recycled rubber particles together to make new products.

The amount of time it takes for PU binders to cure is condition- and product-dependent. For the binder to completely cure and the rubber product to attain its intended qualities, it usually takes a few hours to a day.

Children’s play areas, walking paths, and jogging paths are made with PU binder mixed with EPDM-colored granules.

When making rubber goods, adhesives called polyurethane (PU) binders are utilized. They form a strong link between the rubber granules, making the surface resistant to wear and tear. Its sports surface applications are many.
