Polyurethane

Low mould costs with high quality and verified durability have made our polyurethane products very successful. This success is a direct result of our technical plastics expertise. Knowledge of material and design play an important role in the success of each project.

Designing polyurethane products with clients

Due to our extensive experience, we are able to deliver comprehensive solutions from mould to the finished final product. We provide surface treatments even for the most complex products in our own painting facilities. The component sizes and quality requirements grow hand in hand, the superiority of our products is highlighted. We engage in a close collaboration with our clients, which results in functional, practical and competitive solutions.

Hard integrals

Hard integrals

Hard integrals are cell plastics that consist of a sandwich structure, in which the hard surface and micro-cell core form optimal strength, lightness, rigidity and strength versus weight properties for each structure. The wall thickness can be varied within the same structure from 6 to 30mm avoiding the formation of suction marks on the outer surface. Various traditional materials, such as wood or metal, can be incorporated into the product during the manufacturing stage.

Typical properties in the final product:

  • Virtually unlimited moulding options
  • Good post-processing properties (like wood)
  • Good acoustic properties
  • Good impact strength and durability due to dense surface layer
  • Suitable for painting and serigraphy
  • Average density of final product from 300 to 700kg/m3
  • Fire classification UL-94 VO (5.9mm wall thickness)

The typical mould materials are epoxy and aluminium.

RIM/RRIM

Massive and flexible micro-cell polyurethane RIM and reinforced RRIM are materials with excellent strength, heat resistance and impact strength properties. RIM and RRIM are suitable for health technology devices and transportation equipment. They are mechanically strong and can be used in thin wall components and their wall thickness can be varied.

Typical properties of RIM/RRIM in the final product:

  • Accurate measuring properties
  • Good post-processing properties (like wood)
  • Excellent durability
  • Good electricity insulation and corrosion resistance properties
  • Suitable for painting and serigraphy
  • Can be protected against EMI
  • Recommended wall thickness 4 to 10mm
  • Fire classification UL-94 VO (4mm wall thickness)

The typical mould materials are epoxy and aluminium.

Elastomer

Polyurethane elastomers (polyester and polyether) are rubber-like materials. They can be either solid or cell-like depending on the final product demands.

Polyurethane elastomers have excellent properties such as strength, good durability, good gas, oil and aromatic hydrocarbon resistance and oxygen and ozon tolerance.

Typical properties in the final product:

  • Ability to add different surface patterns with a mould
  • Possibility to use stiffeners
  • Good corrosion resistance and impact strength
  • Good shock-absorbing properties
  • Reduces noise and vibaration
  • Ease of handling
  • Products are dyed throughout or IMC painted
  • Maintains elasticity within range of -25…+70°C
  • Average density of final product  800 to 1200kg/m3

The typical mould materials are epoxy and aluminium.

Cold cure flexible foam and rigid polyurethane foam
Close

Cold cure flexible foam and rigid polyurethane foam

Cold cure flexible foam and rigid polyurethane foam are polyurethane cell plastic materials that are used for example in furniture. The cell foam has an open structure throughout and it does not form a hard surface layer. The elasticity of flexible foam padding can be freely adjusted by altering the amount and mixing ratio of the material. The mechanical properties of rigid foam can be improved by altering its density.

Typical properties in the final product:

  • Virtually unlimited moulding options
  • Adjustable elasticity of cold cure flexible foam
  • Availability of IMO fire classified cold cure flexible foam products
  • Rigid foams are light and durable

The typical mould materials are epoxy and aluminium.

Foil technique

Foil technique facilitates the manufacturing of impressive product without post-processing painting or upholstery. The separate surface layer is cast on top polyurethane foam, and it gives the product finished appearance and is pleasant to touch. The surface layer may consist of either soft or rigid plastic film.

Typical properties in the final product:

  • Finished appearance
  • Pleasant to touch
  • Adjustable rigidity, sound absorption and lightness

The typical mould materials are epoxy and aluminium.

PDCPD

Polydicyclopentadiene PDCPD is a two-component, liquid plastic raw material with low viscosity. It has excellent impact strength, elasticity, lightness, corrosion resistance and painting properties. In addition to good mechanical properties, it is can be processed with more freedom of design compared to for example sheet structures. PDCPD is suitable for the manufacturing of large-scale specifically shaped items.

Typical properties in the final product:

  • Exellent impact strenght properties
  • Good heat resistance: optimal properties for indoor and outdoor use
  • Excellent surface quality, can be painted and glued
  • Excellent corrosion, acid and alkali resistace
    Virtually unlimited moulding options

The typical mould materials are aluminium and steel.
