Description

  • Peroxide Cured EPR Heat Resistant Rubber Sheet 60º Shore is a Peroxide Cured, heat resistant rubber sheet made of EPR (Ethylene Propylene Rubber) rubber, suitable for use in applications where good weather and ozone resistance is required.
  • It also has good resistance to acids and strong bases.
  • EPR is a similar compound to EPDM.
  • However, they differ in the creation processes and in some of their applications.
  • EPR is vulcanized using a peroxide-based cure system, whereas EPDM can use peroxide or sulfur-based systems.
  • This is due to the third monomer, Diene, found in EPDM.
  • When it comes to their applications, little separates the two, except in extreme or demanding applications.
  • EPR, for instance, excels when used in nuclear facilities.
  • EPDM, however, is superior when the applications involve concentrated acetic acids.
  • In most other applications, the differences are near-indefinable.
