The backing is one of the most important components in controlling dimensional stability.
A high-quality non-infill turf system may incorporate:
- Primary backing
- Secondary backing
- Reinforcement mesh
- Polymer coating
- PU or other suitable adhesive systems
Reinforcement can help control deformation and distribute tensile forces more evenly across the turf sheet.
Reinforced Backing
A backing reinforced with materials such as glass-fiber mesh can improve dimensional stability and tensile behavior.
Potential benefits include:
- Better resistance to stretching
- More consistent dimensional behavior
- Improved seam stability
- Reduced risk of localized deformation
PU-Based Backing Systems
Some advanced turf systems use polyurethane-based backing technologies.
Depending on formulation and manufacturing process, these systems may offer:
- Strong tuft retention
- Good dimensional stability
- Resistance to moisture-related degradation
- Consistent bonding performance
However, PU backing should not automatically be considered superior simply because it is polyurethane. The complete formulation and independent test results remain important.
