Rubber floor mats are versatile floor coverings made of natural, synthetic or recycled rubber materials, featuring excellent durability, slip resistance, impact absorption and easy maintenance. Due to their outstanding performance, they are widely applied in residential, commercial, industrial, sports and public environments. This article elaborates on the main uses of rubber floor mats in various scenarios, highlighting their role in ensuring safety, protecting floors, enhancing comfort and reducing noise, so as to provide a comprehensive understanding of their practical value.

Rubber content is the core parameter determining the performance of EPDM (Ethylene Propylene Diene Monomer) granules. This article systematically analyzes the critical impact of rubber content on physical properties such as elasticity, durability, and weather resistance. It provides clear, evidence-based rubber content recommendations tailored to different application scenarios, including residential areas, public playgrounds, school sports fields, and professional athletic facilities. By referencing international standards (e.g., EN 71-3, Labosport) and Chinese national standards (GB/T 14833-2020, GB 36246-2018), this guide helps engineers, contractors, and purchasers balance performance, safety, and cost-effectiveness to achieve optimal material selection.

Yellowing and performance degradation of polyurethane adhesives under ultraviolet (UV) radiation are critical issues limiting their outdoor and long-term applications. This paper elucidates the fundamental causes of yellowing in polyurethane materials and analyzes the underlying mechanisms of anti-yellowing polyurethane adhesives that maintain color stability against UV exposure. The primary anti-yellowing mechanisms include UV energy absorption, free radical scavenging, polymer structure stabilization, and synergistic protection systems. By integrating aliphatic isocyanate structures, UV absorbers, hindered amine light stabilizers (HALS), and antioxidants, these adhesives effectively prevent the formation of yellow chromophore groups, preserve molecular integrity, and maintain long-term transparency and bonding performance. This review provides a comprehensive understanding of the anti-yellowing principles essential for developing high-performance UV-stable polyurethane adhesive formu

Virgin EPDM (Ethylene Propylene Diene Monomer) rubber granules are high-performance synthetic rubber materials manufactured from pure, non-recycled raw materials. This article explores the core raw material composition of virgin EPDM rubber, including primary monomers, auxiliary additives, and the critical processing techniques. It analyzes how these raw materials endow the granules with exceptional properties such as UV stability, elasticity, weather resistance, and durability. The article also distinguishes virgin EPDM granules from recycled alternatives, highlighting their superior quality and reliability for high-standard applications like athletic tracks, playgrounds, and industrial safety surfaces.

This paper systematically compares two prevalent techniques for creating decorative patterns on EPDM (Ethylene Propylene Diene Monomer) colored surfaces: spray painting and direct colored granule inlay. It analyzes the core differences in material composition, construction processes, aesthetic effects, durability, safety performance, and economic costs. The research reveals that while spray-painted patterns offer advantages in fine detail and cost-efficiency, granule-inlaid patterns excel in long-term color stability, seamless integrity, and impact absorption. This comparison provides a practical reference for selecting the optimal pattern application method based on project requirements, budget, and expected service life.

Virgin Ethylene Propylene Diene Monomer (EPDM) granules are high-performance synthetic rubber materials manufactured from pure, newly polymerized EPDM raw materials. This article focuses on the fundamental properties of virgin EPDM raw materials, the complete production process from polymer synthesis to granulation, and the superior performance characteristics derived from virgin materials. Compared with recycled or blended rubber granules, virgin EPDM granules exhibit excellent UV resistance, weatherability, elasticity, color stability and long-term durability. This paper systematically elaborates the chemical composition, synthesis principles, production technology and core advantages of virgin EPDM materials, providing theoretical and practical references for the selection and application of high-quality rubber granules in sports surfaces, playground safety paving and outdoor engineering fields.
