"Transparent polyether flame retardant TPU is Covestro flame retardant TPU" detailed introduction
Halogen-free flame retardant TPU polyurethane raw material, polyester/polyether, hardness: between 71A-95A, the processing level can be divided into: injection processing / extrusion processing , Color: black/white/natural color/transparent, surface effect can be glossy/semi-matte/matte, quality: no powder, no precipitation, cold resistance, hydrolysis resistance, oil resistance, wear resistance, weather resistance, flame retardant grade: UL94-V0/V2, can pass: VW-1 (vertical burning without dripping) test when making wires.
The flame retardant grade of TPU is the same as that of general wire products. It is better to achieve V1 and ordinary V2
Halogen-free flame retardant TPU polyurethane raw material, polyester/polyether, hardness: between 71A-95A, the processing level can be divided into: injection molding / extrusion processing , Color: black/white/natural color/transparent, surface effect can be glossy/semi-matte/matte, quality: no powder, no precipitation, cold resistance, hydrolysis resistance, oil resistance, wear resistance, weather resistance, flame retardant grade: UL94-V0/V2, can pass: VW-1 (vertical burning without dripping) test when making wires.
Thermoplastic polyurethane elastomer (TPU) has good mechanical properties, wear resistance, solvent resistance, high and low temperature resistance and other comprehensive properties, is an ideal wire and cable wrapping material. However, TPU itself is easy to burn, and it is accompanied by molten droplets when burning. The unextinguished molten droplets can easily ignite the surrounding flammables and aggravate the occurrence of fires.
Therefore, if thermoplastic polyurethane elastomer (TPU) is to be widely used in the field of wires and cables, it is necessary to further improve its flame retardancy. Halogen-free flame retardant TPU is not easy to burn, low smoke when burning, low toxicity, reduces harm to human body, and is also an environment-friendly material, which is the future development direction.
In recent years, many polyurethane manufacturers and plastic modification factories at home and abroad are conducting research on the flame retardant technology of polyurethane. However, due to the difficulty of preparing halogen-free flame retardant TPU, the mechanical properties, surface properties and processing properties of TPU after adding flame retardants are greatly reduced. At present, the halogen-free flame retardant TPU cable materials produced by some domestic manufacturers cannot take into account the balance of flame retardant properties, mechanical properties and processing properties. Although the cable materials introduced by foreign imported materials such as Nuoyu and BASF have good performance, their prices are high and their applications are limited.
In response to the needs of this part of the market, Greeneer® GS03 and GS04 series of environmentally friendly halogen-free flame retardants developed by Taiwan Guiyang Technology. The application of nano-inserted dispersion tech can meet the requirements of UL94V-0 flame retardant, which can make the wire products easily pass the VW-1 test.
1. The features of the product are as follows:
® GS03 and GS04 belong to phosphorus-nitrogen series non-halogen flame retardants, but they have the addition ratio of halogen and fireproof effect.
2. The addition amount is small, 10%~25% is enough to achieve VW-1, and the original properties are highly preserved. Combined with nano-inserted dispersion tech, it shows amazing dispersion in TPU material, and the twin-screw of general strength can be processed smoothly.
3. It has excellent material dispersibility and compatibility with TPU, and can be made into high-concentration TPU masterbatch to improve the diversity of processing.
4. It has the advantages of no precipitation, no frost, and good water resistance. ® GS03 and GS04 do not contain any halogen anti-drip agent, and have strong anti-drip ability.
2. Suggestions for use:
1. It is recommended to use Greeneer® GS03 and GS04 alone as flame retardants to maintain the excellent physical properties required by TPU. TPU transparent elastic band
2. Due to its own surfactant characteristics, other organic and inorganic flame retardants can be added in use to achieve synergistic effects and reduce . The flame-retardant engineering plastics containing this product can be used for various extrusion and injection processing, and can meet various processing requirements.
