Polyurethane Soft Foams are derived from the chemical reaction between polyol and isocyanate. The liquid, homogenized mixture reacts exothermically without energy input. For these systems the designation became generally accepted "cold-cure moulded foam", because of the low temperatures of the tools, in which the parts are foamed. In contrast to that "hot foam material" is manufactured in tools, which are heated briefly in very hot ovens, in order to cure the polyurethane foam. In moderate temperatured tools the reaction components froth up . Under pressure formation the reaction mixture fills the tool completely, at the same time air in the tool are exhausted. The foam part can be de-moulded after curing and supplied to its intended purpose. |

| Which advantages provides parts from PUR cold-cured moulded soft foam? | |
| First of all the almost unlimited creative possibilities have to be mentioned. Additionally carrier and fixations can be easily integrated. High resilience, low compression set and low compressive strength fatigue guarantee a durable and reliable quality. Soft foam parts can also be equipped in sub ranges by special heat shields for highly stressed thermal areas.
Important: With soft cold-cured moulded parts you have a serviceable product in the hand. These products can easily be reproduced, both often and accurately. |

| Where can you use parts from cold-cured moulded foam? | |
| Consider, for example, the automotive industry, where high quality, longevity and comfort are demanded: With automotive seating, central arm rests and head restraints. Also the entire sound insulation e.g. engine packaging, and their carpet back foaming is included.
Seat and furniture industries use cold-cured moulded foam parts for backs -, seat and side elements. Due to the relatively large volume these parts are foamed with a low density. At chair furniture soft foam is used for seats, backs and cushions: Thin cushions with relatively high specific gravity, which are padded afterwards. Particularly in this area the creative possibilities of cold-cured moulded soft foam parts come into operation. Further operational areas open with flame-protected systems in aviation as well as with railed and water vehicles. These moulded foam parts can also be used in the medical and optical industry, as well as in the toy and leisure industry.

The material can be optimized by the fact that the density of the part is adapted to the respective requirements. So you can also determine the economic efficiency of the production.
