POLYURETHANE-FOAMS

::: Material Characteristics
We used nature as our model.

There are many samples in our natural environment for the following principle: to produce a material, which is not only compact, but also built up like honeycombs in a cellular construction, which guarantees high solidity in spite of low weight and economical need of materials.

Polyurethane-foam has an open-pore-structure with a very wide range of applications. Therefore we meet this material nearly everywhere and troughout the day. Polyurethane-foam is a safe and stable organic material, chich is being produced out of crude-oil by various synthetic processes.

::: Special Characteristics
load-capacity & elasticity
Polyurethane-foam has a high load-capacity but is elastic and flexible like a down-filled cushion at the same time; the required material features are being achieved by adjusting the production process.
physiologically neutral
Polyurethane-foam is physiologically neutral and regarding toxicity-characteristics it is generally recognized as safe.
resistant
Polyurethane-foam is highly resistant against acids, alkaline solutions and moisture. In addition to that, the open-pore-structure effects the compensation of temperature-differences.
purifying
Polyurethane-foam can easily be purified, washed or disinfected.
Noise
Polyurethane-foam effects a very good noise-absorption.
thermal conductivity
The thermal conductivity of Polyurethane-foam is approx. 0,04 W/mK.
CFC
The production of Eurofoam-polyurethane-foams is strictly done without using CFC's, heavy-metal-elements and AZO-colors.
Environment
Polyurethane-foam is not corrosive and does not spoil ground-water sources. In case of incineration the same amount of critical elements will be set free as during the incineration of other organic materials, such as: wood, coal, leather or cork.

::: Applications
Eurofoam is producing Polyurethane-foams as Polyether- and Polyester-Qualities.
These foams are being used in many different branches, such as:
Polyether Furniture
Mattresses
Upholstered furniture
Polyester Textiles
Shoulder pads
Noise protection
Polyether and Polyester
 Automotive (private and commercial vehicles, lamination)
Household articles (cleansing and bath sponges)
Shoes

::: Types Explanation
As block-type-foams the following qualities are produced:

::: Production
Raw- and process materials (such as: polyol, TDI, water, emulsifying agents, stabilizers and colors) are being transported by pumps and via separated piping systems towards a mixing head . After agitating and mixing all components the mixture is being applied smoothly to a paper-covered conveyor-belt with adjustable width. The conveyor-belt is moving at a speed between 3 - 9 meters per minute, and produces an "endless" block up to a height of 1 meter, which depends on the required density. According to specific recipes Eurofoam can produce foams with equal densities, but different compression stress values.
The result: a very big variety of foam qualities, which enables Eurofoam to meet nearly all specific customer´s demands and applications. At the end of the production line the blocks are being cut into lengths and stored for the ripening process.
The most important advantages of the Eurofoam production-facility are:
• high and constant level of quality as a result of computer-assisted check of recipes
• changing of recipes and/or colors during the production-process is possible
• the width of blocks can be varied during the production-process

::: Ready-made products
After the necessary ripening process the blocks of polyurethane-foam are being transported to the various cutting- and machining centers.
According to customer's requirements, Eurofoam delivers flexible ready-made solutions:
• cut-into-lengths-blocks, with or without trimming
• rolls, with or without trimming
• rolls out of short-cut-blocks, for small quantities, without specified lengths per roll
• sheet cuttings, with or without trimming
• punched parts
• three-dimensional cuttings
