KEPA

KEPA

KEPA 1130 is an ethylene-propylene-based EP (a special high-molecular rubber in which maleic anhydride is grafted onto DM) whose main molecular chain is only a single structure. It has excellent heat resistance, ozone resistance and weather resistance, and it is made of amorphous rubber and exhibits excellent properties in low-temperature impact strength.
KEPA 1150 is a special polymer rubber obtained by grafting maleic anhydride onto a polyolefin-based elastomer whose main molecular chain consists only of a single structure. It has excellent ozone resistance and weather resistance, and it is made of amorphous rubber and exhibits excellent properties in low-temperature impact strength.
