EPDM rubber sealing strips are very suitable for refrigerated box doors, mainly because their superior performance can effectively ensure the stability of the internal temperature of the box and prevent the entry of external hot air, thereby achieving energy saving and improving refrigeration effect.
Product Features
Low temperature resistance
EPDM rubber has excellent low temperature resistance and can maintain elasticity without hardening at extremely low temperatures.
Good sealing
The elasticity of EPDM rubber enables it to fit tightly to the door seams of the cabinet to form a reliable seal.
Ozone resistance and weather resistance
The ozone resistance and weather resistance of EPDM rubber enable it to resist the erosion of environmental factors such as ultraviolet rays, ozone, moisture, and is not easy to age, crack or harden.
Chemical resistance
EPDM has good tolerance to many chemicals such as detergents, greases, acid and alkali solutions.
Water resistance
EPDM rubber has excellent resistance to water and will not deform, swell or corrode due to long-term contact with water.
Food grade
EPDM rubber is non-toxic, odorless, and meets high standards of food safety.
