Mold flexibility

In more recent years, molded flexible foam products are becoming more popular. The bulk of the molded flexible urethane foam is employed in the transportation industry, where it is highly suitable for the manufacture of seat cushions, back cushions, and bucket-seat padding. TDI prepolymers were used in flexible foam mol ding ia conjunction with polyether polyols. The introduction of organotin catalysts and efficient siHcone surfactants faciHtates one-shot foam mol ding, which is the most economical production method.

Molded flexible urethane foams have been used for producing intricate foam products, such as automotive seats and furniture cushions. Molded foams are composed of high-density foam skin and low-density foam core. An example of density distribution of a 10-cm thick molded mattress foam is shown in Figure 9.

Transportation markets have historically been a major user of polyurethane products. Molded flexible foam cushioning provides superior seating and significant reductions in assembly labor costs. This demand will experience some decrease early in the 80 s as autos become smaller but should recover later in the decade. 

Although on the order of 90% of the foam volume used by the furnishings industry is made by the flexible slab foam industry, molded flexible foam is also used for some commercial furniture and mattresses. Most of the molded foam is used by the auto industry.

In the late 1960s the blow-molded flexible plastic 2-quart (1.89 1) canteen was developed to provide additional water for the soldier. The 2-quart canteen also utilized the molded NBC cap. It came with a nylon carrier that was lined with fleece-like material. The concept was that the fleece could be soaked with water and evaporation would keep the liquid in the canteen cooler for a longer period of time. Initially there were several suppliers of the molded 1 and 2-quart canteen and cap. However, both items were eventually put on the US Federal Procurement List (FPL) for manufacture by blind persons. The FPL started in 1938 and is established by the President s appointed Committee for Purchase from People who are Blind or Severely Disabled.
