The right choice of polymer material

You can optimise plastic component features such as product lifetime, thermal properties, stability, temperature and UV resistance.

Polymer or plastic? 

In short, all plastics are polymers, but not all polymers are plastics. Confused? Don’t be – we’ll guide you.  

Both the terms polymer and plastics are often used to describe ‘plastic’ the way consumers understand the term. So let’s have a look at the two terms in order to define them and understand the differences. 


Polymers consist of chains of molecules or monomers.Thus, polymers are molecules made of often large amount of smaller, identical molecules. There are a number of different types of polymers, often categorized in three overall groups:  

  • Natural polymers (like proteins) 
  • Processed polymers (like rubber) 
  • Synthetic polymers (like thermoplastic and other raw plastic materials) 

So, polymers are the building blocks of a wide range of raw materials, including plastic materials – but can also be the building blocks in other natural or synthetic materials such as wool and others.  


Plastics – a part of the polymer family 

Plastics are a specific type of polymers, comprised of a long chain of polymers.  

Plastics are primarily derived from oil or petroleum and natural gas. Thus, they're organically-based materials which are further processed into many different “synthetic” types. 

The various types of plastics all have different structures that determine their properties, like rigid or soft, flexible, and so on. These characteristics, and their combinations, are limited only by the imagination. 

Endless possibilities with plastic

Plastics can be formed into an enormous variety of complex shapes; it can be rigid or flexible, and it can facilitate design solutions in thousands of applications. Plastics can also be co-extruded to achieve a combination of properties.

Primo can find a plastic solution which in most cases will be superior to any other materials you may have in mind. 

Furthermore, product properties can be improved by mixing different types of materials or adjusted with colours and additives according to your needs – and always concerning flexibility, sustainability and recyclability.

Plastic advantages

Multifunctional: Plastics can be rigid or soft,  light or heavy – any colour – any application for any purpose. Plastics are ideal materials for purposes like for instance insulating, protecting, covering and decoration.

Strong and resistant: Plastics offer high impact resistance and bending strength. Plastics are non-corrosive and resistant to weather, acids, lye, solvents and oil. Furthermore, they are UV-resistant and offer perfect water resistance.

Low friction: Plastics have a low friction coefficient and are ideal for durable and moving parts such as gears, cogwheels, conveyor belts, bearings etc.

Eco-friendly: Plastic is non-conductive and energy-saving in production, transportation and maintenance – plus it can be recycled and reused.

Eco-friendly and sustainable use of plastics 

The properties of thermoplastic make extruded plastic profiles perfect for recycling since thermoplastic products can be melted and reused a number of times – usually without changing the material properties and qualities.  

Thermoplastics are easily recyclable, compared to for instance thermosets, because the polymer chain does not degrade when melted. 

Besides thermoplastics, Primo uses other types of sustainable plastics materials like biodegradable plastics and bio-based plastics.

Traceability & documentation

Computer control and monitoring ensure that all information is updated during production.

Our tracing system is a part of our ERP system, Oracle, with an integrated quality module that guarantees one hundred per cent control.

All Primo products are fully documented, and data sheets can be delivered by request.

Digital monitoring of the polymer extrusion manufacturing ensures traceability

We have 60 years of experience with testing and documenting the properties of a wide range of plastics materials, and we are here to share those insights with you.
