PROCESS FOR FOAMING POLYOLEFIN COMPOSITIONS USING A FLUORORESIN/BORON NITRIDE MIXTURE AS A NUCLEATING AGENT

Title:

PROCESS FOR FOAMING POLYOLEFIN COMPOSITIONS USING A FLUORORESIN/BORON NITRIDE MIXTURE AS A NUCLEATING AGENT

Document Type and Number:

WIPO Patent Application WO/2017/166004

Kind Code:

A1

Abstract:

The process of foaming a polyolefin composition using as a nucleator a combination of a fluororesin and a boron nitride at a fluororesin-to-boron nitride weight ratio of less than 4: 1. The synergistic effect between these two nucleating agents results in a higher nuclei density and a foamed product with a smaller average cell size as compared to processes using and products produced by the use of neat PTFE or neat boron nitride alone as the nucleating agent.
