$fractionation.Solid foams Solid foams form an important class of lightweight cellular engineering materials. These foams can be classified into two types based on their pore structure: open cell structured foams (also known as reticulated foams) and closed cell foams. Open cell structured foams contain pores that are connected to each other and form an interconnected network which is relatively soft. Open cell foams will fill with whatever they are surrounded with. If filled with air this could be a relatively good insulator, but if the open cells fill with water, insulation properties would be reduced. Foam rubber is a type of open cell foam. Closed cell foams do not have interconnected pores. Normally the closed cell foams have higher compressive strength due to their structures. However, closed cell foams are also generally denser, require more material, and consequentially are more expensive to produce. The closed cells can be filled with a specialized gas to provide improved insulation. The closed cell$ $arm rests, baby seats, shoe soles, and mattresses. The closed mold process, more commonly known as reaction injection molding (RIM), injects the mixed components into a closed mold under high pressures.Ballistic foam is a foam that sets hard. It is widely used in the manufacture and repair of aircraft to form a light but strong filler for aircraft wings. The foam is used to surround aircraft fuel tanks to reduce the chance of fires caused by the penetration of incendiary projectiles.A metal foam is a cellular structure consisting of a solid metal, frequently aluminium, containing a large volume fraction of gas-filled pores. The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam). The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces. The strength of foamed metal possesses a power law relationship to its density; i.e., a 20% dense material is more than twice as strong as a 10% dense material.$

Morning Chris

I did end up picking it up yesterday afternoon. I got there at 4:30

I spoke to John in the factory and he did everything in his power to help me out and when he couldnt find my order he rang becky and she did a U -turn and came back to the office.

You guys have a level of customer service that is second to none. Certainly the best i have seen in a long time!

I just wanted to say thanks.

Lee
