一、Product Introduction

FR613M is a TPU (polyester) special flame retardant masterbatch, which can also be used in polyether type with a large amount of additives. FR613M flame retardant masterbatch is applicable to the European Commission's RoHS directive, REACH, and IEC 61249-2-21 policy regulations. It has excellent characteristics such as low filling amount, significant flame retardant effect (achieving 3.2Mm and 1.6Mm UL 94 V-0 levels), no precipitation and whitening in raw materials, not easily hydrolyzed, and excellent production and processing characteristics. The enterprise's products can meet many industry regulations such as electronics, electrical equipment, cables and wires, and are suitable for the current regulations on TPU flame retardant efficiency, low smoke and non toxicity, and green environmental protection. TPU specific flame retardant masterbatch, as an additive injection molding flame retardant masterbatch, can achieve good flame retardant effect in TPU recycling. It can be directly injection molded for use without the need for further granulation processing. And it has the advantages of not corroding molds.
