Flame Retardant Polyethylene Sheath Material

Category:

Flame Retardant Polyethylene Sheath Material

Description

Foreword

The flame retardant polyethylene sheathing material is made of polyethylene resin as the main raw material, adding an appropriate amount of inorganic flame retardants, halogenated flame retardants, antioxidants, lubricants and other processing aids. After mixing, extrusion Granular plastic made by granulating and granulating.

Product name, model and purpose

The flame retardant polyethylene sheathing material produced by our company is light in weight, good in mechanical properties, and also has very good low temperature resistance, good environmental stress crack resistance, good processability, and excellent electrical insulation properties. It has a very wide range of applications in the field of flame retardant cables. The product names, models and main uses are as follows:

Name	Model	Primary use
Flame retardant polyethylene jacket	ZRPE (OI≥26)	It is used for high-voltage cables, control cables and optical cables with high environmental crack resistance requirements, and the maximum working temperature is 90°C.
High flame retardant polyethylene jacket	GZRPE (OI≥28)	It is used for high-voltage cables, control cables and optical cables with high environmental crack resistance requirements, and the maximum working temperature is 90°C.
