Rubber flooring mats are widely utilized in recreational, commercial and industrial flooring systems for their superior safety, elasticity and environmental adaptability. Adhesive proportioning is a critical manufacturing and construction parameter that governs the interfacial bonding state between rubber granules and directly determines the molding quality and long-term service performance of finished mats. Different from macroscopic structural failure caused by extreme proportion deviation, subtle mismatches in adhesive proportion can induce latent defects such as inconsistent molding shrinkage, poor interfacial adhesion and attenuated weather resistance, which gradually degrade the overall performance of rubber mats in long-term service.

Rubber flooring mats are essential functional facilities for home and commercial gyms, whose thickness directly determines shock absorption, anti-slip performance, noise reduction effect and service scenarios. Selecting a reasonable mat thickness is critical to protecting building floors, reducing sports injuries, lowering exercise noise, and improving the overall service life of fitness equipment. This paper systematically classifies common thickness specifications of gym rubber mats, analyzes the functional advantages of mats with different thicknesses, and matches them with corresponding fitness scenarios including light aerobic exercise, functional training, heavy weightlifting and group fitness.

Rubber mats are widely applied in sports venues, public facilities, industrial sites and residential spaces due to their excellent shock absorption, anti-slip and wear-resistant properties. The adhesive mixing ratio is one of the core technical parameters that determine the overall performance of rubber mats, directly affecting the bonding strength, structural stability, mechanical properties and service life of finished products. Unreasonable proportioning of rubber particles and adhesive will cause a series of quality defects, including particle shedding, surface hardening, poor flexibility and shortened service cycle. This paper systematically analyzes the influence mechanism of adhesive mixing ratio on the key performance of rubber mats, discusses the quality problems caused by excessive or insufficient adhesive dosage, and summarizes the optimal proportioning principles and construction control points.

EPDM (Ethylene Propylene Diene Monomer) colored granules are widely applied in sports venues, children’s playgrounds, municipal walkways and commercial flooring due to their excellent elasticity, weather resistance, anti-aging performance and environmental friendliness. The weight composition of EPDM granules, including EPDM rubber matrix, inorganic fillers, plasticizers, color pigments, vulcanizing systems and functional additives, is the core factor that determines the mechanical properties, color fastness, service life and comprehensive cost of finished products. Improper component weight ratio matching will lead to common defects such as insufficient elasticity, easy fading, brittle cracking and poor wear resistance.

EPDM (Ethylene Propylene Diene Monomer) colorful granules are high-performance synthetic rubber composites widely used in sports surfaces, playgrounds, and leisure areas. Their formulation consists of EPDM rubber matrix, mineral fillers, plasticizers, vulcanizing agents, color pigments, and functional additives. This article systematically elaborates on each component’s chemical structure, content range, and functional mechanisms, as well as their synergistic effects on the granules’ weather resistance, elasticity, color stability, and mechanical strength. The composition ratio directly determines the quality and service life of EPDM granules, providing a theoretical basis for material selection and quality control in related industries.

Ethylene Propylene Diene Monomer (EPDM) granules are high‑performance synthetic rubber materials widely used in sports surfacing, playground safety flooring, industrial flooring and construction sealing. This article systematically introduces the chemical composition, core physical and mechanical properties, main applications, quality control indicators and sustainability advantages of EPDM granules. It focuses on analyzing the relationship between EPDM content, filler system and weathering resistance, as well as the performance differences between high‑grade EPDM granules and ordinary rubber granules. The research shows that EPDM granules with an EPDM content of more than 20% and a reasonable vulcanization system have excellent UV resistance, ozone resistance, elasticity and color fastness, which can meet the long‑term use needs of outdoor facilities and provide safe, comfortable and durable surface solutions for various scenarios.
