SAN plastic, also known as Styrene Acrylonitrile copolymer, is a widely used thermoplastic material known for its excellent combination of strength, transparency, and chemical resistance. This article aims to provide an insightful overview of SAN plastic, highlighting its properties, applications it offers in diverse industries. Read on to explore the world of SAN plastic and uncover its potential for your specific needs.
1. What is SAN Plastic?
SAN plastic, or Styrene Acrylonitrile copolymer, is a type of thermoplastic material that is formed by the copolymerization of styrene and acrylonitrile monomers. The copolymerization process involves combining these two monomers in specific ratios and subjecting them to polymerization reactions.
The composition of SAN plastic typically consists of a majority portion of styrene and a smaller portion of acrylonitrile. The exact composition can vary depending on the desired properties and application requirements. Generally, the styrene content ranges from 70% to 80%, while the acrylonitrile content ranges from 20% to 30%. The styrene monomer contributes to the rigidity, transparency, and processability of the material. It provides good impact resistance and imparts favorable aesthetic properties to SAN plastic.
