What is a PU rubber binder made of?

A PU rubber binder is made from polyurethane resin and is used as an adhesive to bind rubber particles together in products like rubber mats, playground flooring, and athletic tracks.

What are the benefits of using PU binder in rubber goods?

PU binders improve strength, flexibility, and durability. They enhance bonding and help rubber products last longer and perform better.

To what extent do PU binders improve rubber products?

PU binders offer superior bonding strength, durability, flexibility, and resistance to weather compared to other materials, ensuring long-lasting rubber products.

Is it possible to use PU binders outside?

Yes, PU binders are ideal for outdoor applications because they resist weather conditions, temperature changes, and UV exposure.

How is a polyurethane binder mixed with rubber?

PU binders are usually mixed with rubber granules to form a slurry which is then applied to a surface. Once cured, it forms a strong and flexible rubber layer.

Is it possible to recycle rubber using PU binders?

Yes, PU binders help recycle rubber by binding recycled rubber particles into new products, promoting sustainability.

When applied, how does a PU binder typically cure?

Curing time varies by condition and product, but normally takes a few hours up to a day for full curing.

Are EPDM-colored granules compatible with PU binder?

Yes, PU binder is commonly mixed with EPDM-colored granules for walking paths, jogging tracks, and children’s play areas.

When would you use a PU binder?

PU binders are used in manufacturing rubber surfaces to create strong bonds between granules, making the product durable and wear-resistant, especially in sports surfaces.
