Properties and advantages of EPDM rubber.

Performance
Aging-resistance
Weather resistance: EPDM rubber can maintain good performance under various climatic conditions, such as high temperature, low temperature, sun exposure, rain, wind and frost. This is because there are no unsaturated double bonds in its molecular chain, making it less prone to aging reactions such as oxidation and ozone cracking. For example, EPDM rubber products that are exposed outdoors for a long time, such as car window seals, can still maintain elasticity after years of exposure to sunlight and rain, and will not easily crack or harden.
Heat resistance: In high temperature environments (up to around 150 ℃ for continuous use), its physical and chemical properties are relatively stable. Can be used to manufacture rubber products that work in high-temperature environments, such as rubber components in car engine compartments.
Chemical Resistance
It has good tolerance to most media such as acids, bases, salts, and water. For example, it can be used to make sealing gaskets for chemical pipelines, which can prevent leakage and ensure the safe operation of pipeline systems when transporting liquids containing acidic or alkaline substances.
Low temperature resistance
It has excellent low-temperature resistance, low glass transition temperature, and can maintain a certain degree of elasticity at around -50 ℃. This allows it to function normally even in cold environments, such as in northern cold regions where sealing materials for buildings can prevent the intrusion of cold winds and air.
Insulation
EPDM rubber is a good electrical insulation material, characterized by high insulation resistance, low dielectric constant, and low dielectric loss. It can be used to manufacture insulation layers for wires and cables, ensuring the safety of current transmission and reducing energy loss.
elasticity
Has good elasticity and tensile strength. The tensile strength can reach 15-18MPa, and the elongation can reach 400% -500%. Capable of withstanding significant deformation without easily breaking, suitable for making various rubber products that require elasticity, such as rubber springs, seals, etc.
advantage
Excellent comprehensive performance: EPDM rubber combines various excellent properties such as aging resistance, chemical corrosion resistance, high and low temperature resistance, etc. It stands out among many synthetic rubbers in terms of comprehensive performance and can meet the requirements of various complex working conditions.
High cost-effectiveness: Compared with some high-performance but expensive specialty rubbers, EPDM rubber is relatively reasonable in price and can achieve good performance in many application scenarios, with high cost-effectiveness. For example, in the automotive industry, a large amount of EPDM rubber is used to manufacture various seals, shock absorbers, etc., which not only ensures the performance quality of automotive components, but also plays an advantage in cost control.
Good processing performance: The mixing, rolling, extrusion molding, and vulcanization processes of EPDM rubber are relatively easy, and various vulcanization methods can be used, such as sulfur vulcanization, peroxide vulcanization, etc., which can meet the needs of different production processes and facilitate the production of rubber products of various shapes and sizes.
Good environmental friendliness: It does not contain harmful substances such as halogens, and does not produce a large amount of toxic gases when burned, making it relatively environmentally friendly in waste disposal.
