Description

FB-PP302H is a newly developed flame retardant masterbatch designed for use in PP spinning. 


FB-PP302H has several advantages as a flame retardant masterbatch for PP spinning. It is environmentally and eco-friendly, with good compatibility. When used in the production of polypropylene fiber spinning and non-woven fabrics, it allows for stable melt spinning and drawing processes without breaking fibers or affecting glossiness. FB-PP302H also complies with RoHS, REACH, PAHS, and other regulatory requirements.

Usage

FB-PP302H is suitable for use in both copolymer and homopolymer PP, and it does not have a negative impact on the heat resistance of the PP materials.

Ø  In polypropylene fibre spinning:

Typically, a dosage of 2% FB-PP302H is sufficient to achieve a self-extinguishing flame-retardant effect when polypropylene fiber spinning is removed from a fire. If a B2 or higher level of flame retardancy is required, the dosage of the masterbatch may need to be increased to around 5%, depending on the specific application. 

Ø  In injection-molded products, PP homopolymer:

For PP homopolymer compounds, a typical dosage of 2% to 4% FB-PP302H is sufficient to achieve a UL 94 V-2 classification, pass the GWFI 960℃ test, and meet halogen-free standards. 

Ø  In injection-molded products, PP copolymer:

For PP copolymer compounds, a typical dosage of 4% to 8% FB-PP302H is sufficient to achieve a UL 94 V-2 classification, pass the GWFI 960℃ test, and meet halogen-free standards. 

Ø  Attention:

When using FB-PP302H in spinning and injection molding applications, it is important to keep the processing temperature below 200°C and not exceed 230°C. Temperatures above this range can reduce the stability of the flame retardant and cause degradation of the PP material.
