When designing or upgrading a synthetic football pitch, the choice of infill granules is just as important as the artificial turf itself. Infill affects player safety, comfort, durability, heat behavior, and environmental perception of the field.
Among performance infills for football turf systems, SBR rubber infill, EPDM rubber infill, and TPE infill granules are the three most widely used polymer-based options. While all deliver proven playability, they differ significantly in source material, cost, consistency, environmental profile, and typical applications.
This guide compares these three infill types to help you select the most appropriate solution for your project.

Overview: Polymer Infills for Synthetic Football Turf
Polymer infills are installed between turf fibers to:
Support the grass blades
Absorb shock and reduce injury risk
Provide traction and ball response
Protect the turf system from excessive wear
SBR, EPDM, and TPE are all synthetic infills, but they serve different market segments and performance priorities.
Core Differences at a Glance
| Aspect | SBR Rubber Infill | EPDM Rubber Infill | TPE Infill Granules |
| Source material | Recycled tire rubber (crumb rubber) | Virgin synthetic rubber (ethylene-propylene-diene) | Virgin thermoplastic elastomer (plastic–rubber blend) |
| Cost | Lowest cost; most economical option | More expensive than SBR | Similar to or higher than EPDM; clearly above SBR |
| Performance & feel | Good shock absorption and traction; proven for football and rugby | Stable performance across temperatures; soft underfoot, good UV resistance | High comfort, resilient, resists compaction, retains shape long-term |
| Consistency | Variable due to mixed tire sources | Highly consistent size, elasticity, and color | Very consistent; can be manufactured smooth and round |
| Heat buildup | Gets very hot in direct sunlight | Similar heat behavior to SBR | Can be engineered in lighter colors with lower heat retention |
| Environmental profile | Reuses waste tires but associated with microplastic and perception concerns | Virgin material with known composition; not microplastic-free | Virgin, recyclable material; often positioned as lower-impact synthetic |
| Typical positioning | Budget standard for schools and community fields | Premium or “elite” sports pitches | High-performance, sustainability-focused projects |
