Polyester Foams have lower flexibility properties. Their Push-Release curves are far from each other. However, they have higher physical resistances. They are more durable against abrasion, friction, tear and more resistant against chemicals (such as detergents, fry cleaning solvents) as well. Therefore, they are used in the fields where rather technical requirements are prominent such as automotive industry, sound insulation, painting works etc. One of the important fields of use is textile industry (wadding, brassiere). They are preferred in cloth laminations because they are very suitable for flame lamination process. In addition to sunlight endurance it is higher than other foams and another important property is their capability of being shaped by being hot pressed. This property is very important in the preparation of automotive cases. Polyester Foam can also be manufactured in “special types”. The most popular special types are car washing Foam and Hydrophilic Foam.
Car washing Foam:
It is solid and has big pores. They were used for scratching and cleaning the insects which stick the windows of the automobiles in the long distances and named after that. Today, they are used in wall paint applications and other cleaning works.
Hydrophilic Foam:
These foams draw water into their body and keep it there. They are used in impregnation works, cosmetics and cleaning works.
