Nylon 66 (PA66): This transparent or opaque milky white crystalline polymer is moldable with a melting point of 252 ℃ and a brittleness temperature of 30 ℃. It has excellent resistance to acid, alkali, most inorganic salt aqueous solutions, halogenated alkanes, hydrocarbons, esters, ketones, and other corrosion. It is also durable, self-lubricating, and has high mechanical strength.
Sealing Material:
Fluorinated Rubber (Viton): This material offers high-temperature resistance, oil resistance, and resistance to various chemical corrosion. It is highly stable and exhibits excellent aging resistance and ozone resistance. Fluorinated rubber has high gas solubility but a low diffusion rate, resulting in low air permeability.
Spring Material:
SUS316L Stainless Steel: SUS316L stainless steel is an acid-resistant and corrosion-resistant alloy material. It has high-temperature resistance, is easy to process, and has high strength.
