What is red phosphorus flame retardant masterbatch

Red phosphorus flame retardant masterbatch, as its name implies, is a flame retardant containing red phosphorus. Red phosphorus is a white powder with strong hygroscopicity and chemical stability. It is mainly used in the manufacture of matches, lighters, explosives, etc.

The combustion performance of red phosphorus is very good. Its combustion temperature is above 3000 ° C (the ignition point of ordinary wood is about 250 ° C), and it is not easy to self extinguish; However, red phosphorus is flammable, explosive and highly toxic (LD50 is greater than 2000mg/kg). Therefore, safety operation rules and protective measures shall be strictly followed during use.

1. Scope of use:

Used as flame retardant in polyolefin resin or ABS resin; Suitable for flame retardant treatment in various polyolefin plastics such as PE, PP, PVC and other products; It can be used for flame retardant treatment of wires, cables and electrical insulation materials.

2. Technical indicators:

Appearance: white powder;

Density: 1.0g/cm3;

Moisture content: ≤ 0.5%;

PH value: 8.0 ~ 10.0;

Burning residue: 0.2%;

Heavy metal content: ≤ 10ppm;

3. Application effect:

(1) This product is non-toxic, harmless and pollution-free, and does not corrode the surface of equipment and pipelines and metal parts; It can inhibit the thermal degradation reaction rate of polymer and reduce the combustibility of polymer, so as to play a role in fire prevention. It can effectively prevent fire accidents caused by smoke generated by thermal decomposition. It has a good role in improving the anti-aging performance of materials, and can also improve processing properties and electrical properties.

(2) The combination effect of this product and ordinary organotin additives is superior to other similar products. Because the addition of this product enhances the thermal stability of the product and improves the mechanical strength. Especially, it has a good toughening effect on nylon 6 fiber. In addition, this product can also significantly improve the weatherability, oil resistance, wear resistance and other characteristics of the product.

(3) The mixing effect of this product with other organotin additives containing halogens is significantly higher than the use amount and use times of other organotin additives, and does not affect the product performance and processing and molding process requirements!
