Compounds,

masterbatches

& additives

I

f an article or paper on

masterbatches is accom-

panied by photos, one of

them is sure to picture open

containers of pigments in

vivid candy colours, making

for the most attractive

illustrations in wiremaking.

To the eye of an expert,

this will not blunt the

vital importance of these

concentrated mixtures of

additives which – together

with compounds – call

for the most exquisitely

precise transmission and

distribution of extrusion

and pelletising power.

A

leading

provider

of

thermoplastic

elastomers

describes a masterbatch as

a “package” for colouring

plastics. It is a package that

has been perfected over

many decades for wire-

makers who have come to

rely on its contents for some

very exacting attributes, not

even excluding electrical

conductivity

and

UV

resistance.
