PURPOSE: An expandable rubber composition is provided to have excellent workability and compressive strain, and to have excellent mechanical properties, especially tear strength and fracture elongation. CONSTITUTION: An expandable rubber composition comprises an elastomer polymer including ethylene and anα-olefin derived unit, a hardening package, and a foaming agent. The foaming agent comprises a compound containing water of crystallization. The elastomer polymer comprises ethylene and a propylene derived unit. The elastomer composition comprises one or more kinds of compounds selected from a group consisting of a processing aid, filler, and a softener, stabilizer, and combinations thereof. A manufacturing method of foaming product comprises a step of foaming and hardening the elastomer composition. |
