Plastic Balls- Polypropylene
Polypropylene balls have excellent chemical resistance and low density, as well as the highest melting point of the volume thermoplastics. Polypropylene balls also have high tensile strength. They are an excellent electrical insulator, with low dielectric constant and loss factors. Polypropylene balls are highly resistant to acids, alkalis, alcohols and Many inorganic chemicals, and are non-toxic.
