Rubber Grade Magnesium Oxide as an Acid Acceptor for Compounding

Martin Marietta Magnesia Specialties is a manufacturer of many unique and specialty grades of magnesium hydroxide and magnesium oxide. Customers around the globe specify our products.

Elastomag® MgO
It's like Time management for your Compounding Cycle
  • Engineered to ensure high activity
  • Stabilizes compounds up to 90 days
  • Repeatable cure rates
  • Excellent for fluoroelastomer applications
  • Suitable for every rubber application requiring MgO
  • Uniform particle size
  • Elastomag® products come in a variety of Grades
  • Available in 50 pound bags and 5 pound cartons

Consistent Quality for Minimum Cycle Changes, Minimum Losses, Maximum Stability
The key to successful compounding is the accurate timing of activity, the property that regulates the rate at which MgO accepts acidic byproducts. To predict activity Martin Marietta's Elastomag® magnesium oxide products are scrupulously manufactured to precise specifications in size, surface area, porosity and dispersion characteristics.

Martin Marietta’s precision means maximum predictability on the manufacturing floor. By knowing in advance, the exact activity rates of Elastomag® magnesium oxide, processors eliminate unnecessary cycle changes, reduce stock losses, and maintain control over product consistency.

Elastomag® is available in the following formulations:

  • Elastomag® 170 - A high activity, powdered magnesium oxide of uniformly small particle size.
  • Elastomag® 170 Special - Similar to Elastomag® 170 powder, but tested and assured to have a median particle size of less than 2.6 microns.
  • Elastomag® 100 - A high activity magnesium oxide powder but of lower activity than Elastomag® 170.
