**EPDM Rubber Properties and Characteristics:**
– EPDM is classified as an M-Class rubber under ASTM standard D-1418.
– It is composed of ethylene, propylene, and a diene comonomer and is typically compounded with fillers and plasticizers.
– Crosslinking of EPDM occurs mainly through vulcanization with sulfur.
– Mechanical properties include a non-transparent black appearance, hardness ranging from 30-90 Shore A, tensile failure stress of 17MPa, elongation after fracture of ≥ 300%, and variable density from 0.90 to 2.0g/cm.
– Thermal properties encompass a linear coefficient of thermal expansion of 160µm/(m·K), a maximum service temperature of 150°C, a minimum service temperature of -50°C, and a glass transition temperature of -54°C.
– EPDM exhibits excellent weather resistance, high thermal stability, good electrical insulation properties, superior ozone resistance, and resistance to acids, alkalis, and polar solvents.
**EPDM Rubber Applications:**
– EPDM is commonly used in external harsh environments due to its superior resistance to heat, light, and ozone exposure.
– It is widely employed for sealing, gasketing, membranes, and diaphragms in various industries.
– Specific applications include automotive weatherstripping, roofs, and waterproofing membranes, electrical insulation, radiator and cooling system hoses, as well as seals and gaskets.
**EPDM Rubber Manufacturing Process:**
– The manufacturing process involves the use of ethylene and propylene monomers.
– Polymerization is conducted to create the base EPDM material.
– Vulcanization is employed for cross-linking the polymer chains.
– The material is then mixed with additives and fillers before being extruded or molded into final products.
**EPDM Rubber Advantages and Sustainability:**
– EPDM rubber is known for its durability and longevity, requiring low maintenance.
– It offers a wide temperature range tolerance and is considered an environmentally friendly material that is easy to recycle.
– These advantages make EPDM a preferred choice for various applications in different industries.
**EPDM Rubber Market Trends and Outlook:**
– The demand for EPDM rubber is growing in the construction industry, particularly for waterproofing applications.
– Its usage in the automotive sector is also increasing, driven by its properties and versatility.
– Global consumption trends, competitive landscape, and key players in the EPDM rubber market are essential factors shaping the industry’s future.
