Product details

Product Introduction

Polystyrene (PS) is a transparent thermoplastic in natural, but addition of pigments can make it into masterbatch with many colours. It is also one of the most commonly used thermoplastics in the world, with several million tons produced every year. PS can be solid or foamed due to its weak barrier to liquid or gas. For PS colour masterbatch, solid granules are the common practice. 

PS colour masterbatch has a wide application in making protective casing (i.e. CD, DVD case), containers, trays and disposable cutlery, etc. In comparison, the usage of expanded PS (XPS), such as disposable food containers, has been reduced significantly in recent years as it cannot degrade and hardly recyclable. To get a well dispersed PS colour masterbatch, intermeshing twin screw extruders are commonly used with three different pelletizing method: water strand pelletizing, water ring hot-face pelletizing and under/in water pelletizing.
