POWERSIL® XLR® 630 A/B is an especially low viscous, two-component silicone compound with excellent processing properties. The vulcanized rubber is noted for the good mechanical properties as well as for the excellent dielectrical behaviour.


  • ready-to-use, two-component system
  • extreme low viscosity as a liquid rubber
  • excellent processing with suitable mixing and dosing equipment (low pressure mold filling)
  • excellent dielectric properties
  • best suitable for outdoor applications (UV & weathering resistance, excellent hydrophobic properties)

Spezifische Merkmale von POWERSIL® XLR® 630 A/B

  • kriechstromfest
  • niedrige Viskosität

Components A and B are delivered ready to use in drums of 20 and 200 litres capacity. They can be pumped by means of standard metering equipment from these drums and mixing in a static mixer straight into the heated mold. The mixing ratio is 1 : 1.

The extreme low viscosity and resulting high volumetric flow rate ensure consistent, void-free production at constant mould temperature, also of large-volume moulded parts. The very low inner mould pressure minimizes the danger of deformation of FRP tubes or other inserts.

At room temperature, mixtures of A and B components have a pot life of at least two days.

The "Best use before end" date of each batch is shown on the product label.

Especially in warm climate, storage of the material in an air-conditioned warehouse with cool (below 25 °C) and dry conditions is mandatory.

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.
