Perspex SA manufactures two different grades. Our High gloss has a top surface that is shiny and the bottom is matt. The second grade does not have a GPPS layer and this provides you with a Matt/Matt surface finish on both sides of the sheet. Due to the increased availability of raw materials, HIPS pricing has seen some improvement for Quarter one and we remain optimistic for the balance of 2022.
