Plastic Compounders Foresee Growing Market

Plastic compounders accounted for a global market worth $59.1 billion in 2019, with an expected annual growth rate of 5.2% from 2020 to 2027.

It’s a market that meets the need for specialized materials for a broad array of end uses. To accommodate these applications, custom compounders alter the physical, thermal, electrical or aesthetic characteristics of plastics by incorporating a wide range of materials, including:

  • Antioxidants
  • Processing aids
  • Colorants
  • Additives to improve wear resistance
  • Blowing agents
  • Lubricants
  • Fillers
  • Reinforcements
  • Antistatic agents
  • Slip/ anti-slip agents
  • Anti-block agents
  • Flame retardants
  • Light stabilizers
  • Impact modifiers
  • Cross-linking agents

These additives are generally combined with plastic resin and melted in an extruder. The melted compound exits the extruder in strands, which are cooled and cut into pellets.

Advantages of Using Plastic Compounders

Toll compounding presents several advantages for plastics product manufacturers:

It extends manufacturers’ capacity, reducing the need for additional equipment.

Custom compounding allows companies to manufacture products with enhanced properties beyond those presented by the base plastic resin. It also creates specialty compounds that can set a manufacturer’s products apart from a competitor’s.

Aside from developing custom materials, plastic compounders also can meet manufacturers’ proprietary formula requirements. A good custom compounder will follow your recipe to a T, delivering specific compound ratios.

Plastic compounders can meet a wide array of order sizes, ranging from small batches for experiments or promotions to large runs for major manufacturing operations.

Identifying the Right Compounder

But how do you know you’ve found the best plastic compounder for your application?

Getting answers to the following questions is a step in the right direction:

  1. Does the plastic compounder understand your industry’s regulatory and environmental standards?
  2. Do they have local support in your region?
  3. Does the compounder have the equipment and expertise necessary to produce consistent quality products?
  4. What is the compounder’s quality assurance process?
  5. What is the compounder’s customer service reputation?
