BX UV PUR 67

Introduction

BX UV PUR 67 is a new liquid heat stabilizer mixture suitable for polyether and polyester-based flexible foams. It is a BHT-free blend that contains small amounts of amine antioxidants. As an equivalent of BASF irgastab PUR 67.

Application

BX UV PUR67 is particularly suitable for stabilizing polyols used in the manufacture of PUR flexible foams. irgastab PUR 67 can also have additional antioxidants, co-stabilizers (e.g. phosphites) and/or light stabilizers (e.g. hindered amine light stabilizers (HALS) like HALS 292, UVA Like UV 1, or UV 1130 added.
PUR67 has good resistance to scorching, fogging, and textile staining. It has excellent resistance to foam discoloration, especially after exposure to gas and/or light. In bulk polyol applications, PUR67 can be used in concentrations ranging from 0.4% to 0.45%, depending on the degree of stability required. In-molded polyol grades, the recommended content of irgastab PUR 67 is 0.05% to 0.1%.
