EMKA shifts production to gaskets made of 100% EPDM


EMKA Beschlagteile GmbH is successively converting the material for the self-clamping sealing profiles of its 1011 range to EPDM (ethylene propylene diene monomer). Until now, the seals consisted of a mix of EPDM and polyvinyl chloride (PVC). With this transition, the EMKA gaskets are once again gaining significantly in quality: The new material has a broader thermal application range with high resistance to weathering, UV radiation and acids, which makes the material particularly durable.

DURABLE, HIGH COMPRESSION MATERIAL WITHOUT CONTENT

Due to continuous investments in its production lines, EMKA succeeds in making the conversion from EPDM / PVC to EPDM / EPDM cost-neutral: The higher quality gaskets, which EMKA manufactures in its plants in Spain and England, are offered at unchanged list prices. The conversion of the profiles takes place successively by reducing old stocks in a timely manner and discontinuing production. First samples and small quantities in the EPDM / EPDM version are already available from stock.

EMKA offers a wide range of gaskets for enclosures and control cabinet design as well as for railway, air-conditioning and hygiene applications. Since the material has a high-pressure elasticity and excellent resilience, it is very well suited for sealing switch cabinets. After stretching or compression, the elastomer returns approximately to its original state. Cellular rubber profiles are soft, offer excellent contact surface with the housing at light pressure and thus provide an ideal seal. Many tolerances on the control cabinet door can thus be bridged. EMKA sealing profiles are particularly high-quality and safe, as numerous certificates according to DIN, VDI, UL or fire protection standards can certify.

The material is very resistant to ozone, aging and weathering and is also highly repellent to hot water and steam. EPDM is not resistant to mineral oils and greases, but it is highly compatible with chemicals.

Overview of the advantages of switching to EPDM
 

  • Equivalent insertion and retention force
  • More significant functional travel with hose seals
  • Lower compression force
  • Better temperature ranges from -40 °C and 100 °C, short-term up to +130 °C
  • Better UV and media resistance
  • Vulcanised rings and frames possible
  • Option to manufacture profiles according to UL, EN 45545-2 or VDI 6022 standards (new tools may be required)
