I. Features

Microencapsulated red phosphorus is a high-efficiency product formed by using the original red phosphorus after ultra-fine grinding, and then by in-situ polymerization on the surface of the inorganic flame retardant and melamine formaldehyde resin for secondary coating. flame retardant.

This product "Ultra High Concentration Red Phosphorus Masterbatch" is a flame retardant masterbatch made of ultra-fine capsule red phosphorus powder as the main flame retardant ingredient and imported high-performance resin and compatibilizer as the carrier.

The biggest features of this product are: less dosage, excellent mechanical strength, migration resistance, good electrical properties, high surface finish, environmental protection, etc. It is an environmentally friendly flame retardant with excellent performance, which can be widely used in polyolefin, polystyrene, polyester, nylon, epoxy resin, unsaturated resin, rubber, thermoplastic elastomer, wire and cable and other industries.

Second, the production process

In addition to the twin-screw extruder, the production of this product also requires a complete set of chemical synthesis equipment, such as: boiler, reaction kettle, pulverizer, emulsifier, dehydrator, dryer, etc., and the technology and process are complex much more.

Three, the application effect

1. The phosphorus content of this product is high, which is about twice that of ordinary red phosphorus masterbatch. If applied to PPO products, only need to add 3%--5% to reach UL94-V0 level.

2. Because the red phosphorus used in this product is ultra-fine capsule-coated red phosphorus, and the carrier used is an imported high-performance compatibilizer, it has high mechanical and mechanical properties.

3. The red phosphorus of this product is organically coated with a special process and the carrier is a compatibilizer, so its anti-migration performance is excellent.

4. The red phosphorus of this product has undergone magnetic iron removal treatment, the carrier is a new material, and it does not migrate, so it has high electrical properties.

5. The carrier of this product is imported new material, and the production process is strictly controlled, which ensures the environmental protection, halogen-free and stability of the product.

6. The surface of the red phosphorus produced by this product is covered with a layer of thermosetting resin, and the particle size is very fine, which does not migrate to the surface.

Three, technical indicators

Four, application suggestions

1. For glass fiber reinforced flame retardant PA66/PA6: the addition amount is 7%-9%, and the flame retardant grade is UL94-VO (1.6mm spline);

2. For PBT material, the addition amount is 8%-10%.

3. For PPO, HIPS and other flame retardants, the addition amount is 3-5%

4. It can also be used in many other thermoplastic and thermosetting plastics, rubber, unsaturated polyester, etc. The optimum addition amount can be explored through experiments.

V. Packaging and Storage

1. Packed in iron drums, lined with film bags, 20kg/drum.

2. Keep away from light and away from fire.
