Comparison of SBR, PU And EVA Backing for Synthetic Turf

Comparison of SBR, PU and EVA backing for synthetic turf

Synthetic turf, as the name implies, is a product that replicates the appearance and functionality of natural grass using artificial materials. At the core of its structure, the backing serves as a crucial component, acting as the connecting link between the turf surface and the underlying grass - roots level. This connection is fundamental for maintaining the stability of the turf under various conditions, ensuring that it remains firmly in place even during intense physical activities. Moreover, it significantly contributes to the overall aesthetic appeal of the turf, presenting a neat and uniform appearance. The quality of the backing has a direct bearing on the service life of the artificial turf. A high - quality backing can withstand repeated stress, wear, and environmental factors, thus extending the longevity of the turf. Additionally, it plays a vital role in enhancing user comfort, whether in sports fields where athletes need a reliable and cushioned surface or in residential lawns for a pleasant walking experience. Therefore, a comprehensive understanding of the different classifications and characteristics of the backing is essential when making a decision on artificial turf selection.

Classification of artificial turf adhesive

Based on different raw materials and production techniques, artificial turf backing can be mainly categorized into the following three types:

SBR backing synthetic turf

SBR (styrene - butadiene - acrylonitrile rubber) backing is a cost - effective option in theartificial turf market. It has gained wide acceptance due to its commendable abrasion resistance. In practical scenarios, such as sports fields where constant foot traffic and friction are inevitable, SBR backing can endure the rubbing action without substantial damage for an extended period. For example, in a local football field that hosts numerous matches and training sessions throughout the year, the SBR - backed artificial turf can maintain its integrity and playing surface quality. Its aging resistance also ensures that the turf does not deteriorate rapidly over time. This makes it a suitable choice for a diverse range of applications, including sports fields with budget constraints, as well as leisure lawns in public parks or residential areas.

PU backing synthetic turf

PU (polyurethane) backing represents the premium segment of artificial turf backings. It is highly regarded for its outstanding weather resistance. Whether facing the harsh rays of the sun, heavy rainfall, or extreme temperature variations, PU - backed artificial turf can maintain its performance and appearance. Take golf courses as an example. These are exposed to various weather conditions throughout the year. The PU - backed turf can resist the sun's UV rays without fading or degrading, and its flexibility enables it to conform well to different terrains. However, this superior performance comes at a cost. The production process of PU backing and the raw materials involved are more expensive compared to SBR. As a result, it is often chosen for projects where quality and long - term durability are of utmost importance.

EVA backing synthetic turf

EVA (ethylene vinyl acetate copolymer) backing is a relatively new addition to the artificial turf industry and is increasingly popular due to its eco - friendly nature. It contains no harmful substances, making it an ideal choice for areas where environmental concerns are a priority, such as kindergartens. Its excellent cushioning properties are a significant advantage, especially in sports venues. For instance, in a basketball court, the EVA backing artificial turf can provide a certain degree of shock absorption, reducing the impact on players' joints when they jump and land. This not only enhances the safety of the players but also improves their overall playing experience.

SBR backing synthetic turf

The most prominent advantage of SBR backing is its affordability. It offers a cost - effective solution for projects with limited budgets. In terms of performance, it exhibits stable physical properties under normal usage conditions. However, when it comes to weather resistance, it is relatively inferior compared to PU. Prolonged exposure to harsh sunlight or extreme weather may lead to faster degradation. In terms of environmental friendliness, although it is not highly polluting, it does not match the eco - friendly standards of EVA.

PU backing synthetic turf

PU backing's excellent weather resistance ensures that it can maintain its performance and appearance over an extended period. Its flexibility allows the synthetic lawn turf to be installed on irregular surfaces without cracking or losing adhesion. From an environmental perspective, it has good environmental performance, as it does not release harmful substances during its service life. However, its high cost restricts its application to projects where quality and long - term durability are the top priorities.

EVA backing synthetic turf

EVA backing stands out for its environmental performance. It is biodegradable to a certain extent, which aligns with the current global trend of environmental protection. Its cushioning performance is top - notch, making it suitable for areas where shock absorption is crucial. However, in terms of wear resistance, it is slightly less effective than SBR and PU. In high - traffic areas, it may show signs of wear and tear more quickly.

Application Scenario

SBR backing synthetic turf

SBR backing is well - suited for schools, where the budget for installing synthetic lawn turf may be restricted. In school playgrounds or sports fields, SBR - backed artificial turf can offer a safe and playable surface at an affordable price. Similarly, in community parks, where the focus is on providing a recreational space for residents without a large investment, SBR - backed turf can meet the requirements. For example, a community park in a suburban area installed SBR - backed artificial turf in its picnic and play areas. The cost - effectiveness of the SBR backing allowed the park to cover a large area with turf, providing a pleasant environment for families at a reasonable expense.

PU backing synthetic turf

Golf courses demand the highest quality artificial turf to ensure a consistent playing experience for golfers. The excellent weather resistance and flexibility of PU backing make it an ideal choice for this application. Football fields used for professional matches also require high - quality turf that can withstand intense use and various weather conditions, and PU - backed turf meets these demands. Tennis courts, where the surface needs to be smooth and durable, also benefit from the superior performance of PU - backed artificial turf. A professional football stadium recently replaced its natural grass with PU - backed artificial turf. The new turf not only withstood the rigorous training and match schedules but also maintained its quality throughout the season, regardless of the weather.

EVA backing synthetic turf

Kindergartens prioritize the safety of children. The soft and cushioned surface provided by EVA - backed synthetic lawn turf can reduce the risk of injury if children fall. In sports venues that require good shock absorption, such as trampoline areas or certain types of fitness training grounds, EVA - backed turf can enhance the overall safety and comfort of the users. A kindergarten in a city center installed EVA - backed artificial turf in its playground. The parents were reassured by the soft surface, knowing that it would provide an extra layer of protection for their children during playtime.

In conclusion, the choice of synthetic lawn turf backing should be carefully considered in light of the specific requirements of the application scenario. Each type of backing, SBR, PU, and EVA, has its own unique set of advantages and limitations. By understanding these in detail, one can make an informed decision to achieve the best results in terms of performance, durability, and cost - effectiveness.
