PU Binder Applications
PU binders supplied by Pro Sports Infra are commonly used in:
- EPDM & SBR Sports Flooring Systems
- Jogging Tracks & Playgrounds
- Gym Rubber Flooring & Shock Pads
- Rubber Tiles & Rubber Rolls
- Coating & Printing Applications
- Industrial & Commercial Bonding
PU Binder Performance Characteristics
The curing rate of polyurethane binders depends on:
- Substrate type
- Ambient temperature
- Relative humidity
For faster curing, hot press application can be used to significantly reduce curing time, ensuring efficient project execution.

PU Binder – Frequently Asked Questions (FAQ)
What is a PU rubber binder made of?
PU binders are made from polyurethane-based polymers that react with moisture to form strong, flexible bonds.
What are the benefits of using PU binder in rubber flooring?
PU binders improve strength, elasticity, weather resistance, and longevity of rubber flooring systems.
Can PU binders be used outdoors?
Yes, PU binders are weather-resistant and suitable for outdoor applications such as playgrounds and athletic tracks.
How is PU binder mixed with rubber granules?
PU binder is mixed evenly with EPDM or SBR rubber granules using a mechanical mixer before application.
Is PU binder compatible with EPDM colored granules?
Yes, PU binders work extremely well with EPDM granules, maintaining color vibrancy and surface integrity.
How does a PU binder cure after application?
PU binders cure through moisture reaction, forming a strong elastic bond over time.
