VISCOELASTIC FOAM

08.02.2016

Liquids which flow freely such as petrol, paraffin, alcohol and water are said to be mobile whilst those that do not easily flow such as treacle, honey, glycerine and lubricating oils are called viscous. The property of resistance to flow in fluids is called viscosity. Elasticity is the ability of a material to return to its normal shape after being subjected to stretching or compression by an ext...

BASOTECT® MELAMINE FOAM

07.01.2016

Amino polymers are defined as polymers formed by the interaction of amines or amides with aldehydes, the two most common amino polymers are urea-formaldehyde and melamine-formaldehyde. Basotect® (BASF registered trademark) is an open celled melamine-formaldehyde foam. Melamine is produced by heating urea in the presence of ammonia at high temperatures and pressures. The reaction involves th...

Reticulated Foam

15.12.2015

Polyurethane foams are produced by forming a polyurethane based polymer concurrently with a gas evolution process. Provided these two processes are balanced, bubbles of gas are trapped in the polymer matrix as it is formed and a cellular product results. Surfactants are used in the manufacture of polyurethane foams to emulsify the liquid components, regulate cell size and stabilise the cell s...

HYDROPHILIC FOAM

26.11.2015

Polyether polyols having molecular weights between 2000 and 7000 are used for the production of polyether polyurethane foams. They are produced by adding propylene oxide and ethylene oxide to triols and/or diols. By varying the functionality of the starter alcoholic mixture it is possible to optimise the desired properties of the foams manufactured. One class of polyether polyols used for flexi...

Pre-Polymers

24.11.2015

A polymer may be defined as a large molecule comprised of repeating structual units. The word POLYMER is derived from the Greek word of poly meaning many, and meros meaning part. A large molecule is usually regarded as one having at least a molecular weight of 1000. The term MACROMOLECULE means a large molecule and comes from the Greek word macro meaning large. Macromolecule is often used synon...

Some Properties of Polyurethane Foams

26.10.2015

The characteristics of flexible polyurethane (PU) foams are predominantly determined by the starting materials and the formulations used in their manufacture. Commercial polyurethane foams are nominally manufactured within a density range of 15 to 80kg/m3. The choice of density that a foam converter uses for a particular application will be determined by the end use of the foam. As was mentioned ...

Sound reduction foam for local cafeteria

08.10.2015

Last month we assisted a client in deadening noise within a busy cafeteria that has an adjoining flat. The architect and builders who are renovating the cafe, had a problem with the owner of the flat who complained that the noise coming from the cafe would cause a lot of problems.The builder contacted Technical Foam Services to see if we could suggest a material which would help reduce the noise. ...

Polyurethane Foams

28.09.2015

Polyurethanes can be defined as polymers which contain urethane groups NH CO O in the main polymer chain. Several types of polyurethanes PU are commercially significant and can be classified, Flexible foams, Rigid foams, Elastomers, Fibres, Moulding compositions, Surface coatings and Adhesives. The first commercial polyurethane foams were developed in 1950 by Bayer in Germany, and were based on...

Factors influencing effectiveness of Sound Absorbing foams.

14.09.2015

Airflow, cell size and density, are the main factors influencing the effectiveness of sound absorption in acoustic foams (aka sound deadening foams). Increasing the cell count (ie the number of cells per 25mm of length) of the foam improves the sound absorption at all frequencies. The acoustic absorptivity a specifies the ratio of un-reflected sound in a series of audio frequencies to an incident ...

Packaging Foam

14.09.2015

An efficient foam packaging material has to meet several criteria, and above all it should provide adequate mechanical damping of un-expected shock to protect delicate devices against damage. The sensitivity of a packaged article is expressed by its G value or fragility factor, and the G value of a packing material is determined by generating cushioning curves. This is done by dropping different w...

Foam Inserts

13.08.2015

This week Technical Foam Services have secured a contract to produce foam inserts to package a very high end set of products (kitchen silver cutlery). The orginal enquiry from the client requested a very complex insert providing various depths of apertures. With Technical Foam Services vast knowledge of different grades of foam and foam processes, we have designed a foam product that fits in perfe...

Reticulated foam cone

06.08.2015

Our Enngineering Department are constantly being challenged. A couple of weeks ago we received an enquiry for open-cell filtration foam, to be shaped into a cone with a central hole. The product is being used as a water filter, so after discussions with the client we recommended they use 45ppi Blue polyether reticulated foam. The dimensions of the cone are 150mm long, with a base diametre of 80mm ...

Acoustic Foam Solution!!!

06.08.2015

Technical Foam Services today have supplied sound absorbing panels to a client who has had noise issues within their office premises. The client contacted us as they had issues within their office with 25 people talking on telephones at the same time, which caused lots of noise pollution, and requested some advice on acoustic foam. At Technical Foam Services, we like to go one step further and sug...

Sound-proofing panels for Opticians store

03.08.2015

This weeks novel project for us was to manufacture a set of eight dual-purpose wall panels, each 2.4 metres long x 1.2 mtres wide. Using 50mm thick white basotect melamine foam, surface and edge covered with a cream leather fabric, each panel is then flash-cut with 240 holes (120 pairs), which will hold specatacles that protrude at 75 degrees. The concept being that the panels act as both a displa...

Microphone windshields

03.08.2015

Fine cell, reticulated polyester foams, with a pore-size of around 60ppi, is used for the manufacture of microphone foam windshields. These are placed over the end of the microphone, and help prevent the sound being distorted into the microphone. The foam eradicates problems such as wind, or the user simply talking too close to the microphone. Our range of 60ppi foams are available in many difffer...

Density and Foam Conversion

22.06.2015

How density has such a big impact on foam conversion Flexible polyurethane open-cell foam is manufactured in a wide range of densities. This is due to the huge number of different applications that foam is used within, ranging from washing up sponges and bath sponges, up to heavy-duty packaging and mattresses. Within Europe, the lowest density is 10kg/m3, which in reality is so light tha...

Disposing of Scrap Foam

27.05.2015

Within the foam industry, the disposal of scrap foam is becoming an increasingly important subject for both the manufacturers and convertors of polyurethane foam. Foam is inherently a volumetric, but light-weight material, so what methods are there to dispose of scrap foam? Flexible polyurethane foams were originally developed during World War II, for use as aircraft coatings. However, prod...
