The polyols and polyisocyanates in rubber foam are liquid polymers which, when combined with water, produce a thermogenic or exothermic reaction. By using a combination of specific types and liquid polymers, rubber foam manufacturers can create flexible or rigid foam rubbers. During the polymerisation process, molecules from polyols and polyisocyanates are cross-linked to form a three-dimensional structure. The importance of blowing agents in rubber foam production cannot be overemphasized, as they are associated with flexibility and rigidity.

Foam rubber can be made into soft rubber or hard rubber products. It is widely used in automobile, aircraft, chemical, daily necessities and other industries, as heat preservation, sound insulation, shockproof materials, and seat cushion, mattress, medical machinery, sanitary products, sporting goods and so on.
Rubber foam uses a blowing agent (usually a gas or gas-producing chemical) to create a large number of small bubbles in a liquid mixture. rubber foam can contain polyols, polyisocyanates, water and additives such as flame retardants, fillers and colorants. There are many different types of blowing agents capable of producing porous structures and the blender can control the foaming by adjusting the amount of water or using surfactants.
1. Waterproof and non-absorbent.
2. Protection - thick rubber foam is ideal for providing cushioning or padding. A simple and economical solution for sealing or insulating projects. Ideal for soundproofing and reducing sound vibrations.
3. Adjustable and flexible - rubber foam is strong enough to withstand tears but is easy to customise and cut to size with scissors or blades. Will easily bend and conform to any shape.
4. DIY and project - Use around the home or workplace to provide a custom padded or insulated rubber foam solution.
5. Light, soft, elastic, not easy to heat transfer.
6. It has the functions of shockproof, shock alleviation, heat insulation and sound insulation.
7. Made of synthetic rubber also has the characteristics of oil resistance, aging resistance, chemical resistance, etc
rubber foams are used for vibration control and shock absorption. They offer higher energy absorption and higher density, predictable performance under compression forces and low permanent deformation under constant resistance. These foams do not widen in compression, which makes them a good choice when space is tight. Applications include hood gaskets in mobile equipment, shock absorbers for industrial machinery and vibration isolators for electrical appliances.
rubber foams are strong, lightweight and moisture-resistant rigid structural materials. They help to reduce product weight and have a high stiffness-to-weight ratio. Other types of structural foams have a sandwich-like structure, with a foam core between two thin, strong layers. Reticulated foams are used in filters and are compounded with biocides, bactericides and other additives. Rubber foam manufactured into elastic mats can be attached to a vacuum tool for manufacturing.
In the rubber foam manufacturing process, sheets or extrusions are transformed into finished products. Water jet cutting enables fine, fast cuts and eliminates the incorrect cuts and material waste associated with manual cutting operations. Custom rubber foam products also support tapes using heat-activated tape systems (HATS) or pressure-sensitive adhesives (PSA). A variety of bonding methods are available for custom gaskets, but not all methods are suitable for foam rubber.
What is rubber foam used for?
rubber foam is used in a variety of applications. rubber foam is most commonly used in sports equipment and fillers, insulation, caulking in masonry and concrete work, gaskets and sound insulation.
How do they make rubber foam?
Foam rubber is usually produced when a gas blowing agent is applied to a liquid mixture. The liquid mixture may contain substances such as polyols, water and colouring agents or flame retardant additives. Eventually, through this process, the mixture cures into the familiar rubber foam.
Is rubber foam a good insulator?
Due to its molecular structure, rubber foam is a good insulator. It consists of small, closed pockets of gas. It is therefore difficult for air, water or sound to pass through it. When something is insulated with foam rubber, heat and cold air will have a hard time escaping through the walls, which helps to regulate the temperature as needed.
Is rubber foam flammable?
Like most materials, rubber foam should be considered flammable, unless the material contains any flame retardant additives. It is worth noting that rubber foam, while still flammable, tends to be less flammable than many other materials.
The difference between rubber foam and sponge rubber
The difference between rubber foam and sponge rubber begins with the composition, continues through the material manufacturing process and extends to the molecular structure. Although the terms 'rubber foam' and 'sponge rubber' are sometimes used interchangeably, the differences between these elastomers may not be obvious. In addition, sponge rubber and rubber foam are used for different types of sealing and insulation applications.
If you don't understand how rubber foam and sponge rubber are manufactured and used, you may choose a material that allows leaks, is not sufficiently cushioned or cannot withstand the environment. Rubber can also crumple, become brittle or lose its compressibility. By choosing a compound based on MTAP (an acronym for Material, Temperature, Application and Pressure), engineers can meet requirements beyond whether rubber foam or sponge rubber is required.
Do you need help with material selection for your next project? Huamei can help you determine whether rubber foam versus sponge rubber is the right choice for your application. We can also explain the differences between these two options and solid rubber materials. As an experienced manufacturer of insulating rubber foam materials, we can also help you with your choice of rubber foam.
We offer rubber foam sheets in a variety of sizes and thicknesses so that you get the option that best suits your needs. We also offer rubber foam skins, which are thinner and ideal for more specialist projects. If our standard sizes do not meet the needs of your specific application, please contact us for more information on cutting rubber foam into custom sizes. We are committed to providing a hassle-free shopping experience. If you have any questions while shopping with us, please contact us for further assistance.
