Ethylene Propylene Diene Monomer (EPDM) granules are widely used in sports surfaces, waterproofing materials, and automotive sealing products. The rubber content is a core indicator that directly determines the elasticity, wear resistance, durability, and overall performance of EPDM products. This paper systematically reviews the mainstream detection technologies for rubber content in EPDM granules, including solvent extraction, thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), elemental analysis, and rapid field testing methods. It elaborates on the detection principles, operational procedures, accuracy, advantages, limitations, and applicable scenarios of each method. Furthermore, it combines domestic and international standards such as GB/T 14833-2020, ASTM D297, and ISO 9924-3 to analyze the standard requirements and quality control benchmarks for EPDM rubber content.

EPDM (Ethylene Propylene Diene Monomer) rubber granules are widely used in playground surfacing, sports flooring, and landscaping projects due to their excellent durability, UV resistance, shock absorption, and color stability. The construction quality of EPDM granules directly determines the service life, safety performance, and aesthetic effect of the finished surface. This article systematically summarizes the key precautions throughout the EPDM granule construction process, including pre-construction preparation, on-site construction operations, post-construction maintenance, and safety and environmental protection requirements. It aims to provide practical guidance for construction personnel, avoid common construction errors, and ensure that the EPDM surface meets relevant standards and usage needs.

Anti-yellowing polyurethane adhesive designed for EPDM granules is widely applied in EPDM elastic surfaces, playgrounds, sports courts and other projects for its high bonding strength, good flexibility and excellent UV resistance. To guarantee bonding quality, maintain long-term anti-yellowing performance, ensure construction safety and environmental compliance, standardized operation is essential. This article summarizes key precautions covering pre-construction preparation, mixing and application, curing control, storage requirements, safety protection and waste disposal, providing practical guidance for constructors and users.

Ethylene Propylene Diene Monomer (EPDM) is a high-performance synthetic rubber widely used in construction fields such as roofing waterproofing, outdoor flooring, and building sealing due to its excellent weather resistance, ozone resistance, water tightness, and flexibility. The construction quality of EPDM is directly determined by the details of each construction link, and any neglect of key details may lead to problems such as material detachment, water leakage, and shortened service life. This paper focuses on the core details of EPDM construction, systematically elaborates on the preparation work before construction, the key operation points of each construction process, quality control measures, common problems and solutions, and summarizes the key precautions in the construction process. It aims to provide practical technical guidance for construction personnel, ensure the standardization of EPDM construction, and improve the durability and stability of the project. The researc

In the first quarter of 2026, rising requirements for yellowing resistance in outdoor paving, landscape projects and colored pavements have driven rapid technological innovation in anti-yellowing polyurethane adhesives. Several new aliphatic polyurethane adhesives have been launched, featuring stable molecular structures for long-term yellowing resistance under outdoor exposure. These products pass strict weathering tests, providing high bonding strength and low-temperature flexibility while being eco-friendly and odorless. Widely used in bonded stone, permeable pavements and EPDM surfaces, they effectively solve yellowing, cracking and delamination problems of traditional adhesives, leading to steady growth in market application.
