One datasheet per grade, grouped by polymer line. Elastomer grades are development grades: their values are design targets, shown with release limits, methods and the qualification plan, until measured lots replace them. The filled PTFE grades are samples that show how a PTFE datasheet is laid out.
FKM-RGD90P-01
A 90 Shore A peroxide-cured FKM for static seals in high-pressure gas, including sour gas. Built for rapid gas decompression: high modulus and tear strength to resist the expansion of dissolved gas, and a peroxide cure for resistance to H2S and hot water.
FKM-LT90P-01
A 90 Shore A low-temperature FKM for equipment that sees both ends of the temperature range: hot sour production and cold starts, blowdown or arctic storage. Designed for RGD resistance and for sealing at −46 °C under pressure.
FKM-GEN75B-01
A 75 Shore A bisphenol-cured FKM for general O-ring and seal duty in oils, fuels and hydrocarbons to 200 °C. Low compression set and a stable lot-to-lot record make it the base of a seal maker's catalogue.

FEPM-SOUR90P-01
A 90 Shore A FEPM for sour wells, amine corrosion inhibitors, completion brines, bases and steam to about 225 °C. Chosen where FKM-type fluoroelastomers lose to chemistry rather than to temperature.
FEPM-ESP80P-01
An 80 Shore A FEPM for electric submersible pump protector bags, bonded parts and diaphragms: flex-fatigue resistance with FEPM resistance to H2S, amines, brines and hot oil.
EPDM-STM75P-01

EPDM-H2-60P-01
A 60 Shore A peroxide-cured EPDM for PEM fuel cell stack gaskets and balance-of-plant seals: low compression set at 90 to 120 °C for a low closing force over a long life, resistance to humidified hydrogen and air, acidic product water and glycol coolant, low ionic extractables, flexibility for cold starts to −40 °C, and no fluorine.
