Polyurethane products

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 A  Customised from 15 Shore A to 95 Shore A
Hardness in Shore D  Customised from 40 Shore D to 77 Shore D
 Colours Various 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.
