Environmentally friendly flame retardant polyethylene sheath material

Category:

Flame Retardant Polyethylene Sheath Material

Description

Foreword

Environmentally friendly flame retardant polyethylene sheathing material is made of polyethylene resin as the main raw material, adding an appropriate amount of environmental protection flame retardants, antioxidants, lubricants, high-efficiency crusting agents and other processing aids. Granular plastic made by extrusion and granulation.

Product name, model and purpose

The environmentally friendly flame retardant polyethylene sheathing material produced by our company not only has the general characteristics of ordinary flame retardant polyethylene sheathing material, but also has excellent mechanical properties, high flame retardancy, excellent encrustation performance, smoke emission Low volume, no toxic and harmful gas emissions and other outstanding features. With people's attention to environmental issues, the use of halogen-free flame retardants instead of traditional halogen flame retardants is an important trend in the development of cable insulation. Therefore, the application of environmentally friendly flame retardant polyethylene sheathing materials has broad market prospects. The product names, models and main uses are as follows:

Name	Model	Primary use
Environmentally friendly 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.
