Excellent Elongation EPDM O-Ring

Size: Standard and Custom made

Material: Peroxide cure EPDM, others

The elongation of EPDM

The elongation of EPDM is generally between 250-500%, and high elasticity can also reach over 800% (low hardness, high filling oil). Elongation at break=(length after break - length before break)/length before break * 100%. Jiacheng New Material can provide excellent elongation EPDM O-ring based on your material performance data requests.

Elastic of EPDM O ring

Because there is no polar substituent in the molecular structure of Ethylene propylene rubber, the molecular cohesion energy is low, and the molecular chain can maintain flexibility in a wide range, second only to natural rubber and Polybutadiene, and can still maintain at low temperatures.

Strain characteristics of EPDM rubber parts

EPDM rubber parts need to withstand various complex strain states in the actual use process, so its strain characteristics are also very important. The strain characteristics include elastic modulus, tensile strength, elongation at break, and other contents. The elastic modulus is the ratio of stress to strain on a material, which reflects the stiffness of the material during the elastic stage; Tensile strength is the maximum stress that a material can withstand during stretching, reflecting the strength of the material; The elongation at break is the degree of elongation of a material at fracture, reflecting its toughness. And tensile strength and elongation at break are the two most important indicators in strain characteristics.
