Demand of Closed Cell Foam

Pin It

Closed cell foam are independent cells have their own cell structure which results in foam having a higher plastic content and less air content. Closed Cell foams are very strong and lightweight having low moisture and absorption property having flexible nature which resists most solvents that makes it more durable. It can be used to prevent water or air from passing from one area to another and so they are an ideal medium for plugging the gaps.

Closed cell foam manufacturer produced denser which requires more material and as a consequence are more expensive. Closed cell foam are dense enough to insulate air, preventing drafts and also keeping it every time in a regulated temperatures. This density also prevents mould growth because temperature control can cut down on humidity, which spawns mould. In order to maintain their resistance this foams are usually dense and strong, and resemble solids when they fully form. This strength not only helps to insulate buildings and appliances, but also strengthen the applied walls .

In day to day life, its use lot of products made up of closed cell foam used as Seals Gaskets, it is mainly used in packaging also. Other uses are in joint filters, thermal insulation, pipe insulation foam or backer rod foam etc. Every Closed Cell Foam Manufacturer obtaining the technique which have a tolerance and as such when parts are assembled there are gaps, which become parts of the final product. It is very durable which can withstand a large amount of pressure without major distortion. It can be used to prevent water or air from passing from one area to another and so they are an ideal medium for plugging the gaps .

The gases within bubbles can’t escape, and so if a heavy weight is dropped on a closed cell foam the gases are compressed initially and this quality makes a closed cell foam ideal as a shock absorber. Denser is been produced by closed sell foam manufacturer in which it requires more material and as a consequence are more expensive.

It is expensive than open cell foam. The ways in which the foam is used is totally depending on its type. Since closed cell foam is impervious to gases and liquids, it is an ideal medium to use to plug these gaps. This strength not only helps to insulate buildings and appliances, but can also strengthen walls to which it is applied. The closed cells can be filled with a specialized gas to provide improved insulation. The closed cell foams have higher dimensional stability, low moisture absorption coefficients and higher strength compared to open cell foams.

Uses of EPDM Rubber Foam

These days rubber foams are considered as an economical material due to their number of applications and advantageous properties such as light weight, buoyant, acoustic insulation, inertness and good aging. EPDM rubber is an synthetic rubber which is a type of closed cell foam also known as ethylene propylene diene monomer rubber. Its an extremely durable synthetic rubber. It is an elastomer characterized by a wide range of applications.

EPDM foam is closed cell sponge material, which exhibits excellent resistance to weather ozone and oxidation as the foaming material contains a large number of air or other gases, is unfavourable and circulation, especially closed-cell foam material, has completely separated by independent bubble hole, material can obviously reduce of heat conduction has the very end of the coefficient of thermal conductivity combined with the material itself more flexible and good resilience.

Due to the superb air tight and water tight properties of EPDM Rubber Foam it is used within the automotive industry, electronic parts and construction work. It is also a very good material for jointing expansion and closure seals as well as shock absorbent. It foam is most demanded material to all over the world.

The greatest test of a construction material is to responds in actual conditions because of its properties EPDM chosen the best of among.

Some of The Properties of EPDM Rubber Foam:

• Closed cell structure making it impermeable to air and water and therefore an ideal material for sealing against air and water.


• Heat, Ozone and Weather Resistance.


• Resistance to corrosion, some of diluted acids etc.


• Aging properties and will not go brittle over time.


• Resistance to polar substances and steam are also good.


• Very durable and relatively cheap.


• Available in a wide range, high temperature, hard, soft, super soft.


• UV resistant and mechanical properties.


• Wide temperature range.


• Excellent electrical insulating properties.

EPDM rubber foam has gained industry wide acceptance which provides immediate and long term roofing solutions. It is a thermoset elastomer modified to various processes with their physical properties like high strength, UV stability even at lower temperature and can also withstand moisture and steam. EPDM is versatile and is suitable for number of requirements of the industry. EPDM is a very light rubber as compared to other categories of Rubber so the final product is long in length and  more useful.

Closed Cell Foam is Better Than Open Cell Foam

Pin It

Today every Closed Cell Foam Manufacturer obtaining the technique which have a tolerance and when parts are assembled there are gaps, which become parts of the final product. Since closed cell foam is impervious to gases and liquids, it is an ideal medium to use to plug these gaps. This foam is consists of numerous small sealed cavities usually filled with air and in this gas forms discrete pockets in which each one is completely surrounded by the solid material as these foams do not have higher compressive strength due to their structures.

However, Closed cell foam manufacturer produced also denser which requires more material and are more expensive. The closed cells can be filled with a specialized gas to provide improved insulation. The closed cell foams have higher dimensional stability, low moisture absorption coefficients and higher strength compared to open cell foams. All types of foams are widely used as core material in sandwich structured composite materials by manufacturers. In day to day life also we use lot of products made up of closed cell foam used in as Seals Gaskets, it is mainly used in packaging also.

Closed Cell Foam Properties:

• Excellent impact absorbing properties.
• Durable Safe and non-toxic.
• UV resistant.
• Shatter proof.
• Non‐dusting.
• Excellent buoyancy.
• Excellent shock absorption.
• Lightweight.
• Thermal insulation properties.
• Ranges vary from soft and flexible to hard and resilient.
• Superior chemical and grease resistance.
• Non-corrosive.
• Moisture and Chemical Resistant.
• Low water absorption values.
• Strength, Wear and tear resistant.

Closed cell foam are dense enough to insulate air, preventing drafts and keeping in regulated temperature which prevents mold growth as temperature control can cut down on humidity, which spawns mold. In order to maintain their resistance, these are strong, and resemble solids when they fully form which helps to insulate buildings and appliances, but can also strengthen walls to which it is applied. These foams are resistance to Acid, Alkalis, oxidation, ozone.

Gasoline oil, Aromatic hydrocarbons, ketones so its highly recommended by Closed Cell foam Manufacturer for using the comparable to open cell foam. As cells in closed cell foam are independent from other cells in that they have their own cell structure. The resulting foam has a much higher plastic content and less gas content.

The closed cells can be filled with a specialized gas to provide improved insulation. It can be used to prevent water or air from passing from one area to another and so they are an ideal medium for plugging the gaps. The gases within bubbles can’t escape so if a heavy weight is dropped on a closed cell foam, the gases are compressed initially, but want to recover, which makes a closed cell foam ideal as a shock absorber.
