Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a flame-retardant thermoplastic vulcanized rubber material. Background technique [0002] Thermoplastic vulcanizates include blends of dynamically vulcanized rubber and thermoplastic polymers. The rubber may be dispersed in the thermoplastic resin phase as finely divided rubber particles. These compositions already advantageously exhibit many of the properties of thermoset elastomers, yet they are as processable as thermoplastics. Since thermoplastic vulcanizates are advantageously processable like thermoplastics, thermoplastic extrusion techniques are often used to extrude elastomeric articles from thermoplastic vulcanizates. U.S. Patent No. 4,311,628 / 0272,871A1 discloses a method for preparing thermoplastic vulcanizate. The elastomer is ethylene-propylene rubber, the resin is polypropylene, and the vulcanization system is a phenolic resin vulcanizing agent, and stann...
