VORAMERTM MB 3235 Polyol

VORAMERTM MA 5000 Isocyanate

Description

VORAMERTM MB 3235 Polyol is one kinds of EPS polyether glue system and is designed for production of EPS panel.

The polymerization of VORAMERTM MB 3235 Polyol with VORAMERTM MA 5000 Isocyanate produces carbon dioxide blown foams, with very good flowability and adhesive performance between EPS foam and steel.

VORAMERTM MB 3235 Polyol doesn’t contain any physical blowing agent
