Granule is not the name of a special polymer. A kind of form of polymer obtained in petrochemicals, which is in the form of grains and must be melted and shaped for use, is called granule. Rubber granules are small balls of rubber that are obtained inside different devices after shredding tires. In the flooring industry, two categories of granules are used: SBR and EPDM.
What is SBR?
SBR is shortened to Styrene Butadiene Rubber and is equivalent to styrene butadiene rubber. This type of polymer is known as a common polymer that has high efficiency. Due to the availability of cheap raw materials, this polymer material, which is found in abundance, has made it the most widely used rubber around the world. In fact, this polymer material has the highest and largest volume of production related to the rubber industry. The uses of styrene butadiene rubber include the manufacture of tires, shoes, rubber parts, sealants, coating adhesives, cloud-like and sponge products, pipes, conveyor belts, etc. In the flooring industry, granules obtained from the waste of this polymer are widely used to produce flooring.
What is EPDM?
EPDM rubber is a versatile and affordable rubber. EPDM stands for Ethylene Polypropylene Diene Monomer. It is actually a synthetic rubber that is used in a wide range of industries. EPDM is mostly used in the automotive and construction industries due to its excellent resistance to environmental factors such as ozone, UV and different weather conditions. When you need a rubber material that has excellent weather and heat resistance, EPDM is the right choice for your needs. This type of rubber is considered a suitable and cheaper alternative to silicone, because it can last for a long time with proper use. In this way, EPDM rubber can save you time and money depending on your application needs. In the flooring industry, EPDM is used to have a product with high quality and color stability, but it is not very popular due to its high price, and manufacturers use SBR or car rubber granules in their products.
