Polyurethane integral foam is produced by a chemical reaction between polyols and isocyanates. Due to the special composition of the reaction components an integrated skin is formed on the exterior of the moulded parts.
It has a thickness of about 1-2 mm, exhibits high mechanical durability and is largely closed. It can be smooth or textured depending on the nature of the mould. The foam core always retains its cellular structure.

Advantages of Mouldings of Soft and Semi-rigid Integral Foam
The high level of protection is one of the essential characteristics. This is based on the impact-absorbing character of the foam core in combination with the robust, tough and resilient skin.
The mouldings are subsequently omitted, because the design surfaces are produced that transfer the tool structure on the outer skin of the foam part.

Shapes that are not possible with conventional methods are easily realised with integral foam. In addition, elements used to carry and fasten can easily be foamed. Colour is also possible. Additional integration of functions is conceivable in almost unlimited ways.

Fields of Application for Moulded Parts Made of Soft and Semi-rigid Integral Foam
Mouldings made of soft and semi-rigid integral foam materials are primarily used in the automotive industry, e.g. for arm rests, head rests, steering wheels, gear knobs, as well as for front and rear spoilers. Here mouldings made of soft integral foam fulfil the high safety requirements of the automotive industry.
Baur is the first producer to introduce integral foam materials close to the engine encapsulation in motor vehicles.

Industrial customers mainly use integral foam materials for the manufacture of arm rests, arm supports, chair bases, impact buffers, shock absorbers, handles, etc. Here, in one operation, ironing and mounting elements are foamed and the surface of the moulded part is formed. This can, e.g. be provided with a leather grain.

In the medical field integral foam materials can, inter alia, be used for therapy devices, as well as arm or leg supports.

Basically, soft and semi-rigid integral skin foam material is used everywhere where parts are subject to shock and must be protected from temperatures or where a high degree of acoustic insulation is required.
