Sealing Materials for Demanding Processes
Our expertise lies where standard solutions are no longer sufficient. Whether chemically aggressive media, extreme temperatures or strictly regulated industries – INNSEALS develops and supplies sealing materials that are precisely tailored to the respective application.
In doing so, we combine in-depth materials expertise with a clear understanding of the requirements of industrial processes. The result: solutions that deliver technical performance and prove reliable in long-term operation.
Hygienic & Certified Sealing Materials
Food & Pharma
In the food and pharmaceutical industries, the highest requirements apply to purity, traceability and media compatibility. Sealing materials must not only perform technically – they must also be demonstrably compliant.
INNSEALS supplies elastomers and plastics that are tested and certified for use in hygiene-critical applications. Our materials meet the requirements of relevant standards and approvals, including FDA, USP Class VI, 3-A Sanitary and the UBA Elastomer Guideline.
- Peroxide-Cured EPDM – FDA Approval
- Peroxide-Cured EPDM – FDA, USP, 3-A Sanitary, UBA Elastomer Guideline
- FKM – FDA, UBA Elastomer Guideline, USP Class VI
- FFKM – FDA, USP Class VI, 3-A Sanitary
- HNBR – FDA • NBR – FDA, UBA Elastomer Guideline, DVGW W270, 3-A Sanitary
- Silicone (VMQ) – FDA, BfR
Seals for Extreme Temperatures
High and Low Temperature
Extreme temperatures place special demands on sealing materials: materials must remain dimensionally stable at continuously high temperatures or retain their elasticity at low temperatures. Standard materials often fail prematurely under these conditions.
INNSEALS offers specially selected high-temperature and low-temperature sealing materials designed for continuous operation under extreme thermal conditions. The selection ranges from cryogenic applications to high-temperature processes in the chemical and process industries.
- FEPM (AFLAS®) – -10 °C to +230 °C
- FKM – -15 °C to +230 °C | Low-temperature variant: -50 °C to +200 °C
- FFKM – -15 °C to +325 °C
- PTFE – -200 °C to +260 °C
- EPDM – -50 °C to +125 °C
- Silicone (VMQ) – -60 °C to +200 °C
- NBR – -50 °C to +120 °C
BAM-Tested and Standards-Compliant
Gas & Oxygen
The sealing of gases – especially oxygen – places high demands on material selection and material safety. In addition to media compatibility, permeation, flammability and pressure resistance are decisive selection criteria.
INNSEALS supplies sealing materials that are qualified for safe use in gas and oxygen systems. Our FKM materials for oxygen fittings are BAM-tested; NBR materials for gaseous media are certified according to DVGW in accordance with DIN EN 682 and DIN EN 549.
- FKM for Oxygen Fittings – BAM-Tested
- NBR for Gaseous Media – DVGW Certificate in Accordance with DIN EN 682 and DIN EN 549
Sealing Materials for Hydrogen Applications
Hydrogen H2
- FKM – Low Outgassing Rate, High Material Density
- EPDM – Low Outgassing Rate, High Material Density
- Polyurethane (PU) – Low Outgassing Rate, High Material Density
Chemical-Resistant Seals
Chemicals
In the chemical industry, sealing materials are often exposed to aggressive media, elevated pressures and fluctuating temperatures. Incorrect material selection leads to premature failure, unplanned downtime and safety risks.
INNSEALS supplies chemical-resistant sealing materials for critical application areas: FKM for biogenic media as well as hot water and steam applications, and FFKM for applications involving the highest chemical exposure and thermal stress.
- FKM – for Biogenic Media
- FKM – for Hot Water and Steam Applications
- FFKM – Maximum Chemical Resistance and Thermal Load Capacity
For the Oil and Gas Industry
Oil & Gas
In the oil and gas industry, sealing systems are exposed to extreme loads: high pressure, aggressive hydrocarbons, H2S-containing media and explosive decompression events (AED/RGD) place high demands on the material and design.
INNSEALS supplies sealing materials that have been tested and qualified in accordance with the NORSOK M-710 standard – the recognized testing standard for elastomers in oil and gas production. Our portfolio includes FKM, FFKM and HNBR in NORSOK-compliant versions.
- FKM – Tested in Accordance with NORSOK Standard M-710
- FFKM – Tested in Accordance with NORSOK Standard M-710
- HNBR – Tested in Accordance with NORSOK Standard M-710
