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.

The global EPDM (Ethylene Propylene Diene Monomer) granules industry marked a strong start to 2026, driven by a 17.23% quarter-on-quarter price rebound, implementation of China’s strict new national safety standard GB/T 45201-2025, and widespread adoption of advanced continuous production technologies. Market data shows average EPDM prices rose to 25,397 CNY/ton in Q1 2026, reversing a year-long decline. Concurrently, over 89% of Chinese manufacturers have upgraded to closed continuous mixing lines, aligning with low-carbon and high-performance mandates. The sector remains robust amid global raw material volatility, with sports surfaces and playgrounds accounting for over 84% of downstream demand.

The global market for Ethylene Propylene Diene Monomer (EPDM) granules reached a valuation of $2.8 billion in 2024 and is projected to grow at a CAGR of 5.1% to $4.5 billion by 2034, according to a new industry report. Robust demand is fueled by the booming sports infrastructure sector, stringent safety standards for playgrounds, and the construction industry's shift toward durable, low-maintenance, and eco-friendly materials. Key trends include the rapid adoption of recycled EPDM granules, advancements in UV-stable color technology, and the development of low-VOC formulations for indoor applications. Leading manufacturers are expanding production capacities in Asia-Pacific and investing in R&D to enhance product performance and sustainability.
