Vulcanizates made from the peroxide-curing  ELASTOSIL® R 752/50 OH exhibit a very low rebound resilience and high damping capability.


This product can be used within a temperature range of - 55 °C to + 210 °C.


The addition of heat stabilizers at service temperatures of more than 180 °C is recommended.

Specific features of ELASTOSIL® R 752/50 OH

  • High damping

ELASTOSIL® R 752/50 OH is particularly suitable for the manufacturing of low-modulus rubber articles by compression, transfer or injection molding.


Some special applications, such as highly damping elements, require silicone rubbers with low rebound resilience.

The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous incorporation is a must. At processing temperatures below 30°C the stickiness on the roll mill can be reduced. Pot life is depending on the used peroxide and storage condition.

For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".


This product is available in 20 kg and 540 kg cardboard packaging.


Please store the cardboard boxes in a dry and cool place. Already opened boxes should be closed again to avoid any contamination. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
