Industrial Sealing
Industrial sealing is where silicone is chosen for temperature range and compression recovery — and where the wrong grade shows up as a leak three months later.
We supply compounds for moulded gaskets and O-rings, extruded profiles, silicone bags and sleeves, and sheet stock for punched seals. Service conditions range from −60 °C to 250 °C, with compression set and tear strength as the properties that actually decide whether the seal survives.
For chemical service we ask what the media is before recommending anything. Silicone is excellent in water, steam, air and many foods, and poor in hydrocarbons and concentrated acids — if your application is the latter, the honest answer is a different elastomer.
Compression set
Recovery after long hot cycles — the property that decides seal life.
Tear resistance
Profiles that survive installation without nicking or splitting.
Temperature range
−60 °C to 250 °C, with the actual usable range quoted per grade.
Media check
We ask what the seal contacts before quoting, including the failures.
Material Ranges Used in This Sector
These are the product lines we normally quote for Industrial Sealing. If your part needs something outside them, tell us the requirement — custom formulation is a normal request, not an exception.
What Ships With the Material
Every lot leaves with paperwork. What changes by sector is which documents your customer will ask to see.
- COA per batch — hardness, tensile strength, elongation, tear strength and specific gravity on the lot you receive.
- TDS — full curing and processing guidance, not a marketing sheet.
- Compliance declarations — FDA, LFGB, RoHS, REACH, PAHS and VOM as applicable to the grade.
- Third-party test reports — arranged on the specific grade you buy, through SGS or an equivalent laboratory.
Certificate copies are available for download, and we can issue a declaration naming your market and application.
Questions Buyers Ask About Industrial Sealing
Temperature decides it first: silicone holds −60 to 250 °C, EPDM tops out much lower but is far better in water, steam and glycol. If the part sees hot air or needs cold flexibility, silicone; if it sees hot water long-term, EPDM is often the better buy.
Specify the test condition, not just a number — 22 h at 175 °C and 70 h at 200 °C are not comparable. Send the standard your customer uses and we will quote a grade against that exact method.
Yes, both moulded and extruded. Extrusion needs a drawing with tolerances; for moulded parts we also need the groove dimensions so the seal volume is right before the tool is cut.
