Infill

Infill is the loose particles that are brushed into the synthetic turf playing field’s carpet.

Uses:

Resiliency

The taller fibers used today are usually made of polyethylene (PE), a non-abrasive and relatively durable material. However, PE is, chemically speaking, a lazy fiber — it needs other more resilient materials to hold it up. Otherwise it would just fall down and would not last the full warranty period. This is done with infill particles and/or with more resilient nylon fibers.

Shock Attenuation

Infill is often used to absorb the impact of falls.

Ballast

Infill is also used to stabilize the turf carpet. By weighing down the turf, infill can help prevent movement and wrinkling.

You Should Know:

Due to recent public controversies about crumb rubber, alternative infills are getting more attention, and clients are demanding more options. But, all too often, we see clients, designers, and other turf companies look at alternative infill options in a vacuum. They say, “Oh, no crumb rubber? Let’s just substitute something else.” Rather, infill should be looked at as one element of an overall system that is comprised of synthetic turf carpet, infill, and pad, with each element interacting and affecting the others.

Dropping a very expensive alternative infill into the same carpet that would have been used with crumb rubber and sand is wasteful. Instead, AstroTurf has designed systems specifically for alternative infills. With a shorter, denser turf carpet and a pad, you can often get the guaranteed shock absorption of a re-usable pad, the performance of a cutting-edge infill, and increased density and durability from the turf carpet… all for about the same price you would spend sinking more alternative infill into a taller system!

We’ll walk you through a variety of commonly used sports grass infills below.

Available Options:

SBR

sports grass infill

SBR stands for Styrene-Butadiene Rubber. It is by far the most commonly used infill material in synthetic turf fields. It is made of ground up recycled tires.

Features:

  • Most economical shock absorbing infill
  • Most widely studied infill (70+ independent studies)
  • No study has ever found ill environmental or human health effects
  • Absorbs shock
EPDM

EPDM sports grass Infill

Ethylene Propylene Diene Monomer (EPDM) is a virgin rubber material. It is a high quality, high dollar replacement for crumb rubber.

Features:

  • Few issues with quality in the marketplace
  • Attenuates shock
  • Very high melting point
  • No negative perceptions in the marketplace
Z-CAP

ZeoFill sports grass Infill

Z-CAP is a very interesting infill. Used for industrial waste cleanup and sold in healthfood stores, zeolites have a honeycomb molecular shape that allows the material to absorb and contain toxins. This molecular shape also allows it to absorb and slowly release water for noticeably cool field temperatures. Z-CAP is an affordable top dressing to traditional SBR fields that reduces field temperatures substantially.

Features:

  • Absorbs and slowly releases water for lasting temperature reduction
  • Does not require water
  • Does not require additional maintenance
  • Inexpensive alternative infill
BrockFILL®

BrockFILL sports infill

BrockFILL is an engineered wood particle infill specifically designed for artificial turf. It’s made here in the USA from a species of southern pine that is grown, harvested, and replanted in continuous cycles, making it ideal for a sustainable, renewable organic infill product.

Features:

  • Durable
  • Optimal Traction
  • Low Splash
  • Cooling properties
  • No irrigation required
Silica Sand

Silica Sand sports grass Infill

Silica sand is often used for synthetic turf ballast. It comes from multiple quarries throughout the country, contributing to its low cost. Silica sand is often used in combination with other performance infills.

Features:

  • Very inexpensive
  • Widely used and proven
  • No negative market place perceptions
  • Good ballast material
Nike Grind Infill

Nike Grind sports grass Infill

Nike Grind partnered with AstroTurf to deliver cutting-edge turf systems. Nike Grind infill is a rubber infill material that is derived from the excess materials collected during the manufacturing of Nike shoes. The rubber outsoles are collected, chopped up and sized for optimal field drainage, and encapsulated with a premium green coating that bolsters infill resiliency and creates a more uniform and plush field appearance.

Features:

  • Nike Grind is engineered for human contact and conforms to Nike’s stringent quality standards and Restricted Substances List (RSL)
  • Sustainability (Each Nike Grind field diverts 160,000 pounds of materials into next uses)
  • Plush and uniform field appearance
  • Temperature reduction (versus black crumb rubber)
  • One of the more affordable alternative infill selections
  • Absorbs shock
  • No negative public perception
TPE

TPE sports grass Infill

Thermoplastic Elastomers (TPE) are a class of copolymers or a physical mix of polymers (usually a plastic blended with a rubber). These are virgin materials that are either extruded or molded.

Features:

  • Varied shapes of TPE are less likely to compact
  • No perception issues of crumb rubber
  • Attenuates shock
