We’re considering LS Series No.2. The usage range is -15°C to 200°C, but what is the proper storage temperature? Also, what happens to the grease shape at -20°C? We’d appreciate your advice.

Regarding storage temperature, we recommend storing the product within a range of 5°C to 35°C, avoiding direct sunlight.

Storing the product outside this temperature range may increase the risk of oil separation, softening, or hardening over long periods.

As for the condition of the grease at around -20°C, since this product is based on lithium grease, it tends to harden under low temperatures and become brittle—
e.g., like margarine at room temperature (soft and spreadable) vs. margarine kept in the freezer (crumbles easily).

This change is caused by increased oil viscosity and structural changes in the thickener, preventing the grease from maintaining its normal pliable state.

Therefore, we do not recommend long-term storage or use in -20°C environments.

If exposure to low temperatures is temporary, the grease may recover its flexibility once the temperature returns to normal, but for reliable performance, please store it within the recommended temperature range.
