Polymer resin composition for preparing insulating material having reinforced thermal stability

Abstract

A polymer resin composition has EPDM (Ethylene Propylene Diene Monomer) as a base resin. The composition further has the following components based on 100 parts by weight of the base resin: 1 to 5 parts by weight of amine-based antioxidant, and 1 to 5 parts by weight of HALS (Hindered Amine Light Stabilizer). An insulating material can be manufactured using the polymer resin composition providing good thermal stability and also an extended lifespan under high temperatures. Such an arrangement is particularly suitable for use in cables for nuclear power plants.
