Thermoplastic Halogen Free Low Smoke Resistance Fuel (WD-AB)-Small Diameter Control Cable

Category:

Flame Retardant Polyethylene Sheath Material

Description

Foreword

The thermoplastic halogen-free low smoke resistance fuel (WD-AB) is based on halogen-free polymer as the base material, adding halogen-free non-toxic flame retardant, smoke suppressant, heat stabilizer, lubricant, etc. A kind of processing aid, granular plastic obtained by mixing, plasticizing and granulating.

Instructions

If the inner bag fails to prevent moisture or has a long storage time, the material should be dried before feeding and extruding. It is better for the hot material to enter the extruder. It is better to use a low shrinkage ratio (1.25-2.0:1) for the screw. Please contact the supplier first if you use an equidistant and unequal depth single-thread screw or other screw extrusion. Recommended process conditions (for reference only)
