Polyurethane products

Polyurethane forms its own family of polymers. The material is very versatile and combines the mechanic properties of plastic with the elasticity of rubber. This makes the material broadly applicable in the industry.

Ridderflex casts polyurethane products in all possible shapes. We do this both manually and mechanically. Highly complex products, such as three-dimensional products, are moulded through injection moulding. Hollow products are moulded through rotomoulding.

Polyurethane properties

Polyurethane (also known as PU) has a number of special properties:

  • Excellent wear resistance;
  • Good tear resistance;
  • Pressure resistant (only the hard grades);
  • Highly resilient (even the hard grades);
  • Resistant to mineral oils, fuel, greases and various solvents.

Variation in polyurethane properties

From a technical point of view, polyurethane offers more possibilities than rubber or plastic. Because Ridderflex itself mixes the right components into polyurethane systems, it is possible to create a great variety in polyurethane properties. The material can be hard, soft, flexible, tough, light as well as different colours. Almost anything is possible.

Hardness in Shore ACustomised from 15 Shore A to 95 Shore A
Hardness in Shore DCustomised from 40 Shore D to 77 Shore D
ColoursVarious colours possible. For the food industry, white and FDA blue are recommended.

The materials are based on the application of the product. We can influence the polyurethane properties by adding various additives, such as: flame retardants, UV protectors, Mos2, Steel and aluminium powders. We can offer you a great range of possibilities and solutions, because we can always vary in polyurethane properties.

Customised polyurethane products

We can cast or rotomould polyurethane products or cover your product in PU according to your specifications. This can be based on a drawing or model. And is possible in various hardnesses and colours. Our specialists are happy to help you choosing the right material. Please call +31 (0) 180 46 34 71 or send us an e-mail.
