Artificial turf technology has moved far past the short nylon carpet of the 1960s. The biggest recent advances are tougher, more upright fibers, cooler and non-rubber infills, shock pads that drain, single-polymer carpets built for recycling and new PFAS rules. None of it makes turf as cool as grass, but knowing what changed helps you choose a better backyard sports turf.
Key Takeaways
- A 2024 review of 23 studies found synthetic surfaces ran about 17 to 61°F hotter than grass. Cooling fibers and infills narrow the gap but do not close it.
- Monofilament blades are designed to stay upright and resist matting better than slit film.
- Tire crumb now competes with TPE, EPDM, cork, coconut, engineered wood and infill-free designs.
- The Synthetic Turf Council’s guideline keeps impact hardness (Gmax) below 165 for a field’s life.
- Colorado has barred installing turf with intentionally added PFAS since January 1, 2026. Maine bans its sale starting in 2029.
How Has Artificial Turf Technology Changed?
Big-venue turf is traced to 1966 and the Houston Astrodome, where a dense, short nylon carpet went over compacted soil.
Sand-filled carpets came next. The third generation, the type now in common use, arrived in 1997 at a Pennsylvania high school: longer fibers with rubber, or rubber and sand, packed between them.
A 2019 review in Sports Health puts modern pile height at about 1.6 to 2.8 inches, with 1 to 1.6 inches of infill. Recent work targets heat, infill chemistry, cushioning, drainage and waste.
| Component | Older Approach | Newer Options |
|---|---|---|
| Fibers | Short, dense nylon | Longer polyethylene, monofilament or single-polymer fibers |
| Infill | Sand, then tire crumb | TPE, cork, coconut, engineered wood, or none |
| Heat control | Watering | TPE infill, reflective fibers, moisture-holding infill products |
| Cushioning | Foam pad, then rubber infill | Drainable shock pads built to a Gmax target |
| End of life | Hard to recycle | Mechanical separation, reusable TPE infill |
| PFAS | Often undisclosed | State bans, ASTM F3782 testing |
Turf Fibers: Monofilament, Slit Film and Polyethylene
Slit film blades are cut from sheets, slit into grass-like strips and twisted together. Monofilament blades are single, thicker strands designed to resist wear, stand upright and mat down less. Upright fibers are believed to affect ball roll, so monofilament is a common pick for soccer.
Polyethylene is now the most popular fiber, ahead of nylon and polypropylene. Infilled polyethylene turf is also much less abrasive than early nylon carpets, though both are more abrasive than well-kept grass.
Compare denier, the thickness of each filament, which the Synthetic Turf Council (STC) says affects resilience, performance and wear.
Newer Fiber Designs
TenCate builds its ONE DNA carpets from polyethylene alone, fiber to backing, so they can be mechanically recycled where facilities exist.
A bigger change is turf with no loose infill. TenCate says its Pivot system, in development since 2019, earned FIFA certification without infill or a shock pad. Grip and cushioning come from the fiber design itself.
Can Heat Resistant Artificial Turf Stay Cool?
A 2024 systematic review of 23 studies found synthetic surfaces ran about 17 to 61°F hotter than natural grass. Air temperature above the turf was only about 1 to 2°F higher.
Product swaps help less than you might hope. In Penn State’s 2012 heat lamp tests, 11 fiber and infill combinations landed within 12°F of each other, and every one topped 150°F.
What Lowers Surface Heat
- TPE infill. In one study in the review, a TPE plot averaged about 114°F against 128°F for tire rubber.
- Reflective fibers. “Cool climate” fibers reflect sunlight. One study measured about 104°F on them against 82°F grass, and the review warns they may raise radiant heat above the surface.
- Moisture-holding infill products. A product added to the turf helps the infill store water. Treated turf ran cooler than standard turf, yet in one study it still averaged about 153°F against 92°F grass.
- Engineered wood infill. Brock USA says its pine infill typically runs at least 20°F cooler than rubber when dry, and can be 40°F or more cooler when moist, based on its own field comparison.
Tip: Check surface heat with an infrared thermometer before play. The Massachusetts Toxics Use Reduction Institute (TURI) describes a Burlington, Massachusetts schools policy that allowed turf play up to a 120°F surface when the air was below 82°F, and moved activity to grass above that.
Infill Options: Tire Crumb, TPE and Organic Turf Infill
Infill holds the blades upright and adds cushion. Options now go well beyond tire rubber.
| Infill | Made From | What to Know |
|---|---|---|
| Crumb rubber (SBR) | Scrap car and truck tires | Most common; hotter than TPE in tests |
| EPDM | Synthetic rubber | Resists abrasion; keeps its form in heat |
| TPE | Thermoplastic elastomer | Cooler than SBR in tests; reusable |
| Cork, coconut, walnut shells | Plant materials | Less studied; some raise allergy concerns |
| Engineered wood | Southern pine particles | Will not float once saturated, per maker |
| Sand | Silica or acrylic-coated sand | Very fine particles can be a breathing hazard |
In March 2026, California’s Office of Environmental Health Hazard Assessment finalized a study of 35 fields and more than 100 chemicals. The Synthetic Turf Council, an industry group, reports it found crumb rubber turf not likely to harm players or spectators.
TURI, by contrast, sees tire crumb as the infill likely to raise the most chemical concerns, and plant and mineral infills as likely carrying fewer hazardous chemicals.
What Goes Under Artificial Turf? Shock Pads and Drainage Backings
Sports turf sits on a porous base, often compacted gravel. An optional shock pad, up to about 1 inch thick, goes on top, then the carpet. Every layer should let water pass through.
Shock Pads
Impact hardness is measured as Gmax, the peak force of an impact in units of gravity. Lower means softer. The Synthetic Turf Council’s guideline is a Gmax below 165 for the life of a field, and pads are designed to help hold it there.
Modern pads also move water. Brock USA says its expanded polypropylene panels drain vertically at more than 700 inches per hour. The tradeoff: in one study in the 2024 review, a padded plot ran about 3°F warmer.
Drainage Backings
The tufted backing gets a coating of polyurethane, latex or hot melt. Fully coated backings built to drain get holes punched at regular intervals.
Can Old Artificial Turf Be Recycled?
Sports fields are typically replaced every 8 to 10 years, per TURI. Its 2020 fact sheet projected 1 to 4 million tons of used turf waste over the following decade, most of it not fully recyclable. Newer fixes:
- Separation. Re-Match mechanically splits old turf into polymer, sand and rubber without water or chemicals.
- Single-polymer carpets. All-polyethylene designs are built to be mechanically recycled where facilities exist.
- Reuse. The STC notes that TPE infill is recyclable and can be reused as infill when a field is replaced.
What Should You Know About PFAS in Artificial Turf?
PFAS are persistent chemicals, and some last in the environment for centuries. Nonprofit testing found PFAS in turf backing and signs of it in every fiber sample tested. TURI’s PFAS fact sheet says one possible use is as an extrusion aid in fiber making.
Rules are tightening. Colorado’s SB24-081 has barred installing artificial turf with intentionally added PFAS since January 1, 2026. Maine bans sales of turf with intentionally added PFAS from January 1, 2029. California lawmakers passed a turf PFAS ban in 2023, but the governor vetoed it.
ASTM F3782, published in 2026, standardizes how turf fiber and backing are sampled at the factory and tested for PFAS. It does not cover infill or shock pads. STC members committed in 2024 to stop using intentionally added PFAS.
Which Turf Advances Matter Most in a Backyard?
A backyard turf area faces the same issues on a smaller scale. Ask your builder:
- Is the fiber monofilament or slit film, and what is its denier?
- Which infill is specified, and how does it compare with rubber for heat?
- Is there a shock pad, and what Gmax should the surface test at?
- How do the backing and base drain?
- Can the supplier show PFAS test results for the fiber and backing?

Frequently Asked Questions About Artificial Turf Technology
What is the newest artificial turf technology?
Recent advances include infill-free systems that build grip and cushioning into the fibers, single-polymer carpets designed for recycling, alternative infills such as TPE and engineered wood, and shock pads that drain. A new 2026 ASTM standard also sets a consistent way to test turf fiber and backing for PFAS.
Is there artificial turf that does not get hot?
No. Research consistently finds synthetic surfaces hotter than grass in sun, by about 17 to 61°F across a 2024 review of 23 studies. TPE infill, reflective fibers and moisture-holding infill products lower surface temperature, and watering helps briefly. In summer, check the surface before bare feet touch it.
What is the best infill for backyard artificial turf?
It depends on use and climate. Crumb rubber is the most common but ran hotter than TPE in tests. Cork, coconut and engineered wood avoid rubber, though some raise allergy concerns and many are less studied. In hot climates, ask for heat data on each option.
Does artificial turf contain PFAS?
Some has. Nonprofit testing reported by TURI in 2020 found PFAS in turf backing and signs of it in fibers, possibly from extrusion aids. Colorado now bars installing turf with intentionally added PFAS, Maine bans its sale from 2029, and STC members pledged in 2024 to stop adding it. Ask for fiber and backing test results under ASTM F3782 before you buy.
