Where FKM are used
Seals, O-rings and components requiring chemical, high-temperature and oil resistance. Fluoran UR is the De Grandi additive for these compounds.
Why they are chosen
Fluoroelastomers are chosen when service conditions exceed what ordinary elastomers can handle: contact with aggressive chemicals, elevated temperatures, exposure to oils and fuels. Their fluorinated structure delivers stability where other materials would degrade.
They are high-end materials, used where a seal failure is not acceptable and where safety and reliability come first. Hence the importance of high-purity additives in the compound.
Where
Fluoroelastomers are used where performance is critical and conditions are severe.
Fluoran URSeals and O-rings in contact with fuels, oils and high-temperature fluids.
Components where reliability and resistance are absolute requirements.
Seals in contact with aggressive chemicals.
Severe environments, high temperatures and pressures.
The contribution
A high-performance material such as a fluoroelastomer calls for adequate additives. Fluoran UR, high-purity coated calcium hydroxide, acts in the compound as both activator and acid acceptor: it contributes to a consistent curing rate, to thermal stability and to the mechanical integrity of the vulcanisate.
The non-hygroscopic nature of the product ensures that this performance remains unchanged even after months in storage, in any environment.
Full Fluoran UR data sheetFAQ
Fluoroelastomers are used where high chemical, high-temperature and oil resistance are required: seals, O-rings and components for automotive, aerospace, process industry and energy. They are chosen when service conditions exceed what ordinary elastomers can handle.
Because fluoroelastomers withstand conditions that would degrade ordinary elastomers: aggressive chemicals, elevated temperatures, contact with oils and fuels. Their fluorinated structure delivers stability and reliability where failure is not acceptable.
Mainly automotive (seals and O-rings in contact with fuels and oils), aerospace, process industry (seals in contact with chemicals) and energy, including oil and gas, where high temperatures and pressures are involved.
Fluoran UR is De Grandi's high-purity coated calcium hydroxide, used in fluoroelastomer compounding as an activator and acid acceptor. It contributes to a consistent curing rate, to thermal stability and to the mechanical integrity of the vulcanisate — all decisive factors in applications where reliability is the priority.
Fluoran UR is produced by De Grandi at its plant in Tromello, in the province of Pavia, Italy. For enquiries, samples and technical documentation you can contact the company on +39 0382 868402 or at info@degrandisrl.it.
