Plastic Additives

Plastics are not inherently perfect, and general-purpose plastics often have shortcomings in strength, weather resistance, processability, and other aspects, requiring performance adjustments according to different application scenarios. Plastic additives are the ‘invisible key’ to solving these pain points. High-end plastic additives are expensive and in high demand.

In plastic processing workshops, engineers often face the following dilemma:

The carefully formulated formula inexplicably turns yellow during high-temperature processing, greatly reducing the appearance of the finished product.
Newly produced plastic parts lose their toughness and crack shortly after use due to aging.

In order to meet environmental requirements, the raw materials were replaced, but it was found that the flexibility of the product suddenly decreased and the processing difficulty increased…

These seemingly insignificant problems all point to a key point – the choice of plastic additives.

Types Of Plastic Additives

Plastic additives, also known as functional masterbatch, have a wide variety of types, mainly divided into categories such as improving processing performance, mechanical performance, optical performance, aging performance, surface performance, etc., according to their functions.

According to their functions, common plastic additives include:

  • Improving processing performance: lubricants, release agents, stabilizers, processing aids, plasticizers, flame retardants, etc
  • Improving mechanical properties: reinforcing fillers, toughening agents, impact modifiers, coupling agents, etc
  • Improving aging performance: antioxidants, UV inhibitors, mold inhibitors, fungicides, etc
  • Improving surface performance: anti-static agents, anti-blue light agents, slip agents, wear-resistant agents, anti-adhesion agents, anti-fog agents, etc

 

Selection Of Functional Masterbatch Equipment

Different plastic additives require different types of equipment. Small and medium-sized devices account for the largest proportion, with MT36 and MT50 being the best-selling.

In addition, the selection of models varies depending on the raw materials used. It is necessary to set and select the model according to the actual purpose, for example:

  • UV resistant masterbatch: High-speed mixer + Twin-screw extruder L/D 44~48:1 + Water strand pelleting system
  • Silicone masterbatch: Twin-screw extruder L/D 48~52:1 + Water strand pelleting system
  • Defoamer masterbatch: High-speed mixer + Bedroom mixer + Twin-screw extruder L/D 48:1 + Die face air cooling hot cutting system
