Highly Stable Phosphinate Based Flame Retardant for Polypropylene

Highly stable phosphinate based flame retardant for polypropylene--Aluminium Hypophosphite (Al (H2 PO2 )3 is kind of new type phosphorus flame retardant, slightly soluble in water, high purity and high decomposition temperature,Highly stable phosphinate based flame retardant for polypropylene-Aluminium Hypophosphite (Al (H2 PO2 )3 is widely used in engineering plastics, wire and cable compounds.Shandong taixin produce two type Highly stable phosphinate based flame retardant for polypropylene Aluminium Hypophosphite ( Low Sulfate Content,aht-220B ) and regular Aluminium Hypophosphite ( HT-220A) two type Aluminium Hypophosphite (Al (H2 PO2 )3.

Physical and Chemical Properties

Key Advantage

High TGA: TGA(1%) ≥310℃

High Stable Quality:Purity mainly stable in 96.0%-97.5%

Application areas:

1. Automotive polypropylene components

Interior parts: dashboard frame, door panel trim, etc., added 10-12% aluminum hypophosphite, passed FMVSS 302 (automotive material flame retardant test), combustion rate ≤ 50mm/min, and also meets the requirements of light aging resistance (QUV test 500h color difference Δ E ≤ 2);

Engine peripheral components: battery box, intake pipe, etc., utilizing their heat resistance and flame retardancy, can withstand a high temperature environment of 120 ℃ for a long time.

2. Electronic and electrical casing

Home appliance components: air conditioning fan blades, washing machine inner cylinder, etc., with a flame retardant rating of UL94 V-0 and a surface resistivity of ≥ 10 ^ 14 Ω· cm, meeting GB/T 5169.21 (flame retardant testing for electronic and electrical products);

3C product accessories: router housing, charger housing, passed the hot wire test (GWIT ≥ 775 ℃) to reduce the risk of electrical fires.

3. Home and Building Materials

Furniture board: PP hollow building template, cabinet panel, flame retardant grade up to GB/T 8624 B1 level, with both moisture-proof and impact resistance (impact strength ≥ 15kJ/m ²);

Packaging materials: flame retardant PP woven bags, logistics boxes, meet the fire prevention requirements for storage and transportation, and can be recycled and reused.

Packaging :Net weight 25kg/bag, Compound paper-plastic bag and inner aluminum foil

Storage and Attention: Keep in dry, room temperature and moisture proof condition, preventing the heating.
