Rubber flooring has become the standard choice for both home and commercial gyms due to its durability, safety, and versatility. The thickness of rubber mats directly impacts shock absorption, noise reduction, slip resistance, and overall performance. Selecting the right thickness ensures effective protection for floors, equipment, and athletes while optimizing workout comfort. This article explains common thickness specifications, their functional differences, and ideal applications for each, helping gym owners and users make informed flooring decisions.

The adhesive mixing ratio directly decides the bonding effect, structural performance and service life of rubber mats. A reasonable ratio must be formulated by combining multiple influencing factors. This article sorts out the main factors that affect the matching proportion between rubber granules and adhesive, including raw material characteristics, on-site construction conditions, application scenarios and technical requirements. It analyzes the influence mechanism of each factor, and provides reference for scientific batching and standardized construction in actual production and laying.

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.

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.

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.

EPDM (Ethylene Propylene Diene Monomer) granules are premium synthetic rubber materials renowned for exceptional durability, UV resistance, and shock absorption. As a versatile surfacing material, they dominate playgrounds, sports courts, and public spaces, delivering safety, aesthetics, and longevity. This article explores EPDM granules’ composition, core advantages, applications, and quality standards, highlighting their value in modern construction and recreation.
