Some of the most outstanding mechanical and chemical properties of PEEK™ include a low coefficient of friction, high wear and abrasion resistance, dimensional stability at high temperatures, and thermal stability. The thermal stability of PEEK™ is important for its industrial applications, and thermal degradation occurs between the crystalline transition and melting temperatures. Its modulus of elasticity is strongly influenced by its degree of crystallinity, and due to its viscoelastic nature, different values of tensile strength are obtained depending on the temperature. PEEK is lighter than steel, aluminum, and titanium

Polyvinylidene fluoride or PVDF is a highly chemically inert thermoplastic fluoropolymer. It is commonly used in conditions that require high purity, strength, and resistance to acids, bases, and solvents, as well as high temperatures, aging, and ultraviolet radiation.
