The present disclosure provides, among other things, surface coverings with a protective coat applied thereto a rubber material. As provided herein, in some embodiments, a surface covering has or includes an exposed surface that is no-wax. The present disclosure further provides methods of making, and methods of using. Such surface coverings have surprising and beneficial attributes. They are particularly advantageous as resistant to soiling and abrasion. These surface covering are also resistant to crumbling under load. Such surface coverings would be useful as flooring products with desirable properties. In particular, such abrasion and soil resistant surfaces could be useful as a rubber flooring product.

In an example, a process includes polymerizing a mixture that includes an ethylene monomer, a propylene monomer, and a diene monomer to form an ethylene-propylene-diene (EPDM) terpolymer using ring-opening metathesis polymerization (ROMP). The process further includes chemically reacting the EPDM terpolymer with a norbornene-based phosphinate cross-linking material to form a flame-retardant, cross-linked EPDM rubber.

The present invention provides a method for surface-modifying a rubber vulcanizate or a thermoplastic elastomer, which can cost-effectively provide a variety of functions, such as remarkable sliding properties or biocompatibility, according to the application. The present invention relates to a method for surface-modifying a rubber vulcanizate or a thermoplastic elastomer as a modification target, the method including: step 1 of forming polymerization initiation points A on a surface of the modification target; step 2 of radically polymerizing a non-functional monomer starting from the polymerization initiation points A to grow non-functional polymer chains; step 3 of washing the modification target on which the non-functional polymer chains are grown; step 4 of forming polymerization initiation points B on a surface of the non-functional polymer chains; and step 5 of radically polymerizing a fluorine-containing functional monomer starting from the polymerization initiation points B to grow fluorine-containing functional polymer chains.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
