Special masterbatch: is based on user-specified varieties of plastic products, the choice of the same plastic as the masterbatch manufactured by the carrier. Such as PP masterbatch, ABS masterbatch selection of PP, and ABS as a carrier.
Universal masterbatch: some resin (often low melting point of PE) as a carrier, but it can be applied to the carrier resin resin coloring.
Universal masterbatch is relatively simple and convenient, but the disadvantage is more, it is recommended that you use the special masterbatch.
Why many companies do not produce universal masterbatch?
The vast majority of regular masterbatch companies generally do not produce universal masterbatch.
Universal masterbatch there are many shortcomings. In fact, the universal masterbatch 'Universal' range is very narrow, technical specifications, poor economic efficiency, in particular in:
The coloring effect of predictability
The masterbatch is of used to coloring, universal masterbatch pigment in the plastic will show different colors, so the coloring effect less predictable.
(2) affect the other properties of plastic products
In particular, the impact strength of the products are easily deformed, distorted, more obvious to the engineering plastics.
(3) the high cost of
Universal masterbatch order to be able to 'universal', often the choice of the higher heat levels of pigment, resulting in waste.
In addition to coloring, masterbatch whether a flame retardant, brightening, anti-static, anti-oxidation, anti-ultraviolet, and other functions?
The masterbatch can have certain kinds of functions, if the factory requirements in this regard.
Sometimes, the customer does not request the color of the parent company will be required to propose to add some additives, such as adding certain additives in masterbatch, such as brightening agent. Of course, this will increase the cost of the product.
