Gasket

The rubber gasket is positioned between the front cover and the door. It serves to keep the drum watertight while in use and to protect the door from damage upon closing. Therefore the gasket has to be elastic, watertight and long-lasting

The gasket is made of Ethylene Propylene Diene Monomer (EPDM) rubber, and has probably been manufactured with the process of die casting.

EPDM Rubber

Ethylene Propylene Diene Monomer (EPDM) rubber is widely used in sealing and gasketing. EPDM exhibits outstanding resistance to heat, ozone, steam and weather. It is an electrical insulator too. It has a service temperature from -50°C to 150°C which is well beyond the temperature it needs to withstand.

A video on the manufacturing process of EPDM rubber can be seen below.

Synthetic Rubber

Made from various petroleum-based monomers unlike natural rubber
Properties can be altered by changing chemical composition
Generally offers better resistance to abrasion than natural rubber
Superior resistance to heat and the effects of aging
Easier to manufacture than natural rubber.

Natural Rubber

Made from latex, a white, runny, milky liquid that oozes from some plants when you cut them
Has high tensile strength that synthetic rubber can't imitate
Renewable and biodegradable
Moderate resistance to damage from exposure to heat, light and the ozone in the air
Arguably better overall properties than any synthetic plastic.
