Product Description

Rigid Polyurethane Blend Polyols for Refrigerators

DJD-103

Products Introduction

DJD-103 blend polyols use CP or CP/IP as blowing agent, which applies to refrigerators, freezers, and other insulation products. The characteristics of the products are as follows

1.excellent flowability, the density of the foam is well-distributed, and the thermal conductivity is low

2.excellent low-temperature dimensional stability and good cohesiveness;

3. demould time is 6-8 minutes.
