EPDM
EPDM Materials for Seals and Gaskets
Discuss EPDM candidates for the weather, water or formulated-fluid exposure in your assembly. Selection should account for the complete medium, temperature cycle and mechanical requirements.
01 / EPDM
Define the EPDM compound and the interface
Start with the compound reference or required properties, the part drawing and the reason for selection. Describe the installed compression, mating surfaces and movement. A material-family name needs a project specification and identified samples before a purchasing decision.
02 / EPDM
Record the complete fluid exposure
Supply the fluid product, composition and concentration, including additives and assembly lubricant. Coolant, fertilizer solution, water treatment chemicals, urea solution and cleaning agents require their actual exposure conditions.
| Input | What to provide |
|---|---|
| Material | Compound identity, preparation and relevant existing reports |
| Fluid | Full product or specification, mixing ratio and additives |
| Lubrication | Lubricant product, quantity and contact during assembly and use |
| Sequence | Contact, cleaning, drying and changes between media |
| Conditions | Temperature, pressure, duration, circulation and interruptions |
| Material result | Required dimensional or property changes and acceptance limits |
| Assembly result | Installed sample, leak or functional check and approval responsibility |
03 / EPDM
Treat steam as its own exposure
For a steam duty, identify wet or dry conditions, temperature and pressure together, dwell, startup and shutdown, cleaning and installation stress. Define the compound and sample evaluation for that sequence. A dry-air aging result alone does not establish steam service life; agree the evidence for the intended maintenance decision.
04 / EPDM
Define outdoor aging and the installed joint
For an outdoor seal, provide sunlight, ozone, moisture and temperature exposure with the installed strain or compression and any bonded interface. An ozone evaluation needs the concentration, temperature, duration, strain and crack-assessment conditions. Agree both appearance and functional criteria; a material selection is separate from the complete enclosure’s performance.
05 / EPDM
Specify odor or emissions requirements separately
If odor or VOC results matter to the component, provide the customer method, sample state, conditioning, packaging history and acceptance criteria for each evaluation. Identify the actual compound and part tested. An odor observation, a VOC report and a material-property result do not replace one another.
06 / EPDM
Confirm the part, supply form and sample decision
Send the drawing, quantity, packaging and documentation needs. For a sheet or gasket enquiry, define thickness, profile and finished-part requirements so the material and manufacturing route can be discussed. For compound supply, define the receiving process separately. Agree dimensional inspection and assembly approval before repeat orders.
