In this developed era, we can all see the development of the plastic industry. For example, our polyester masterbatch also has a relatively good function and is widely used. Then what raw materials are mainly used for polyester masterbatch? Let's talk to us about it.

Polyester masterbatch is a kind of color masterbatch, so do you know the meaning of the masterbatch, first of all, we should know the meaning of the masterbatch: by a high proportion of pigments or additives and thermoplastic resin, good dispersion of plastic colorant, the resin selected has good wetting and dispersing effect on the colorant, and has good compatibility with the colored material. Namely: pigment + carrier + additive = masterbatch.

And polyester masterbatch is polyester resin as the main body, and then mixed with carbon black or other colors of pigment extrusion, resulting in small particles used in other plastic products for dyeing. Is to take polyester resin as the main body, and then mixed with carbon black or other colors of pigment extrusion to create small particles used in other plastic products for dyeing.

There are two main types of raw materials used for polyester masterbatch: colorant and carrier. According to the different colorant and carrier used, some masterbatch also need to add additives. Usually if the colorant is selected as organic or inorganic pigment, the carrier is selected as a low melting point polymer, generally need to add appropriate additives. If the colorant is polyester soluble dye, the carrier is polyester itself, then generally do not need to add any additives. The former situation is similar to the general plastic masterbatch, but the indicators are more demanding, here will not be repeated. If high-grade polyester masterbatch is prepared, such as filament polyester masterbatch, it is generally considered that polyester soluble dye is used and polyester itself is the better carrier.

The above is about the use ratio of polyester masterbatch raw materials
