Features Of Dow SILASTIC 590 EU Silicone Rubber

  1. Platinum-cured, two-part addition-cure silicone rubber offering excellent dimensional stability and low compression set.

  2. Meets EU Regulation (EC) No. 1935/2004 for food contact materials and is compliant with FDA 21 CFR §177.2600 for repeated-use food applications.

  3. High tear strength and outstanding flexibility across a wide temperature range (–60 °C to +200 °C).

  4. Low viscosity before cure enables easy dispensing, degassing, and mold filling—even in complex geometries.

  5. Excellent electrical insulation properties and resistance to aging, ozone, and UV exposure.

Typical Applications Of Dow SILASTIC 590 EU Silicone Rubber

  1. Food-grade gaskets and seals for industrial processing equipment and packaging machinery.

  2. Medical device components requiring biocompatibility and sterilization resilience (e.g., autoclave, gamma, EtO).

  3. High-reliability encapsulation and potting of electronic sensors and control modules in demanding environments.

  4. Custom molded parts for household appliances, including oven door seals and steam-resistant interfaces.

  5. Prototyping and low-volume production of precision elastomeric parts in automotive and white-goods OEMs.
