Acrylic Balls

GENERAL DESCRIPTION
Acrylics (Polymethyl-Methacrylate or PMMA) is an amorphous thermoplastic which is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio. Common trade names of acrylic include Plexiglas, Lucite, and Acrylite.

GENERAL PROPERTIES
Acrylics offer high light transmittance with a Refractive Index of 1.49 and can be easily heat-formed without loss of optical clarity. Prolonged exposure to moisture, or even total immersion in water, does not significantly effect the mechanical or optical properties of acrylic. Most commercial acrylics have been UV stabilized for good weatherability and resistance prolonged sunlight exposure.

Acrylics are unaffected by aqueous solutions of most laboratory chemicals, by detergents, cleaners, dilute inorganic acids, alkalis, and aliphatic hydrocarbons - however, acrylics are NOT recommended for use with chlorinated or aromatic hydrocarbons, esters, or ketones.

We offer highly quality acrylic balls which are available nowhere else. We also offer colored acrylic balls of optimum quality. Our acrylic plastic balls can be availed at quite reasonable prices. We have also become one of the prominent colored acrylic balls manufacturers in India.
