ELASTOSIL® R 865/40 S

ELASTOSIL® R 865/40 S offers numerous functional advantages. The material ensures superior rebound resiliencey and a minimal compression set.

The compounds are easily pigmentable with ELASTOSIL® PT Pigment Pastes and have good processing characteristics. The various grades (ELASTOSIL® R 865/40 - ELASTOSIL® R 865/70) can be blended in any proportion to achieve intermediate hardness.

 

Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances.


Properties

Specific features of ELASTOSIL® R 865/40 S

  • Food-contact
  • High rebound resilience
  • Ultra-low compression set

ELASTOSIL® R 865/40 S is especially designed for peroxide curing applications as
 

 

  • extrusion 
  • calendering
  • molding

The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous incorporation is a must to maintain best processing behavior. Pot life is depending on the used peroxide and storage condition. Please consider the technical data sheet of the corresponding curing agent.

 

We recommend to use following amount of peroxide:

ELASTOSIL® AUX Crosslinker E: 1.5 % 50% paste of bis-(2,4-dichorobenzoyl)-peroxide in silicone fluid

ELASTOSIL® AUX Crosslinker C6: 0.5 % 45% paste of 2,5-bis-(t-butylperoxy)-2,5-dimethyl-hexane in silicone rubber

ELASTOSIL® AUX Crosslinker C1: 0.3 % (Dicumyl peroxide 98%)

Preliminary tests lead to optimized results.
