Polyethylene and
EVA cellular plastics

Polyethylene (PE) is the most commonly used thermoplastic in the world, and it can be used to manufacture anything from packaging materials to insulation, sealants and protective gear. Our specialists will choose just the right kind of PE for your needs, produce a prototype and manufacture the finished products in series.

What is
PE?

Polyethylene is the most common plastic on the market. Polyethylenes are divided into three categories based on their density: high density (PE-HD), medium density (PE-MD) and low density (PE-LD). Low-density polyethylenes are soft and ideal for plastic bags, for example. High-density polyethylenes are harder materials that are used to make beverage crates, for example. Adding some EVA (ethylene-vinyl acetate) to the material makes it tougher and its consistency becomes slightly more rubbery and flexible.

Benefits of polyethylene

  • Lightweight and affordable
  • Good insulation properties
  • Resistant to moisture, chemicals and temperature variation
  • Good buoyancy properties
  • Suitable for food packages
  • Can be shaped into various shapes
  • Available in various hardnesses and colours

EVA cellular plastic

EVA (ethylene-vinyl acetate) is a copolymer of ethylene and vinyl acetate. It is a soft and flexible elastomer-like material with a wide variety of uses ranging from knee pads and helmet paddings to shoe insoles and various hospital equipment.

We will help you find the material that best suits your needs and produce a prototype of the product, as well as manufacture the product in series at the scale you require. Let us know about your idea – we will help you make it a reality.

What is EVA cellular plastic?

EVA (ethylene-vinyl acetate) is a closed-cell semi-rigid cellular plastic. It has a fine, consistent cellular structure and it is suitable for a wide variety of applications. The benefits of EVA plastic are flexibility, softness, good weather resistance and chemical durability. Furthermore, it has excellent buoyancy, shock absorption and thermal insulation properties.

 

How does EVA differ from polyethylene?

EVA cellular plastic is a softer and more elastic than polyethylene. Different kinds of plastics are often mixed together to give the final product the benefits of the different materials.  The higher vinyl-acetate level of EVA and increasing the EVA level in XLPE plastic foam typically improve impact and tear strength – they increase softness, flexibility and surface friction.  The lower melting point of EVA also improves the thermoplasticity of the mixture.
