注: 建议图片大小150px*50px The PU binder used for EPDM rubber granules is the core material for building high-performance sports fields, designed specifically to firmly bond EPDM granules into a uniform, flexible, and weather resistant surface. It endows the runway with excellent elasticity, durability, and shock absorption performance, ensuring that the track remains stable under extreme temperatures and high-intensity impacts, making it an ideal choice for creating a safe and professional sports space.
FAQ
Q1: What is the recommended mixing ratio of PU binder and EPDM granules?
A: To ensure the best bonding effect and surface elasticity, it is usually recommended to control the weight ratio of PU binder to EPDM granules between 15% -25% (e.g. 1:6 to 1:7). The specific proportion can be adjusted according to the construction environment, granule size, and site functional requirements.
Q2: What types of sports fields is this binder suitable for?
A: Widely used in plastic running tracks, park walking trails, children's play areas, basketball courts, tennis courts, and various indoor and outdoor leisure activity venues, especially suitable for areas that require all-weather use and high shock absorption requirements.
Q3: What are the requirements for temperature and humidity during construction?
A: It is recommended to work in an environment of 10 ℃ -35 ℃ and avoid working in rainy, snowy, or high humidity conditions. If encountering low temperature environment, preheating treatment should be carried out on the material to ensure normal curing.
Q4: Is the product environmentally friendly and safe?
A: Our PU binder strictly follows environmental standards, does not add toxic or harmful substances, has TVOC emissions far below national standards, has no irritating odor, and ensures safety and health during construction and use.
Addressing the core needs of users
We are well aware that in site construction, you face multiple challenges such as material compatibility, construction stability, and long-term durability. Our PU binder is designed to solve these problems: it is not only perfectly compatible with various EPDM granules, ensuring that each granule is evenly wrapped, but also maintains excellent adhesion and elasticity under complex climatic conditions. Whether pursuing beautiful designs with rich colors or professional sports venues that require extremely high wear resistance, we can provide a one-stop solution from material selection to proportioning guidance, making your venue construction more worry free and reliable.
Widely applicable scenarios
Professional sports venues: track and field tracks, semi-circular area, auxiliary area, providing shock absorption and rebound force that meets the standards of the event.
Public leisure areas: park trails, community fitness paths, children's playgrounds, balancing safety and beautiful colors.
Special functional areas: golf course walkways, pedestrian overpasses, school sports equipment areas, providing anti slip and wear-resistant protection.
Excellent product advantages
Super strong adhesion: forms a flexible bonding layer, effectively preventing threshing and peeling, and extending the service life of the site.
All weather performance: UV resistance, ozone resistance, acid rain resistance, can be used after rain, not affected by seasonal temperature differences.
Convenient construction: Supports mechanical paving and manual construction, with controllable curing time, greatly improving project efficiency.
Customer Application Cases
Nordic indoor children's playground: (Anonymous: Copenhagen chain amusement park in Denmark)
Project background: The amusement park is located in a shopping mall and has extremely strict requirements for odor (the mall management requires that the construction period should not affect the business of other merchants). At the same time, colored patterns such as animal footprints need to be pieced together, and the boundaries between particles of different colors should be clear and not mixed.
Solution: Use our colorless transparent PU adhesive combined with 1-2mm six color EPDM particles, and adopt the mold partition paving process. PU adhesive quick drying formula (operation time 25 minutes), layered construction, each layer thickness 6mm, total thickness 12mm.
Usage effect: Construction was carried out at night, and no odor complaints were received from other floors of the mall. The pattern has clear edges and bright colors. After two years of use, the amusement park has reported that there are no loose particles in high flow areas (slide exits, under climbing frames), and daily maintenance only requires cleaning with a vacuum cleaner.
Customer review: "We have tried three types of adhesives, and only this one meets Nordic standards in both color reproduction and environmental indicators
