GPPS Ц general-purpose polystyrene
GPPS (general-purpose polystyrene) is made by continuous polymerization in bulk (bulk-polymerized polystyrene). The product is made in the form of dyed or undyed stabilized granules with residue monomer content. Suspension polymerization and in-bulk polymerization are the main methods in polystyrene production.
GPPS is a solid, elastic, colorless substance, fragile thermoplastic material with high dielectric properties, chemically resistant to alkalis and acids, apart from nitric acid.
For in-depth analysis we seldom refer only to the Foreign Trade Code (Group 3903), but we make our own more precise correlation of GPPS types by each grade of each producer.
