Product Description
Halogen Free Flame Retardant Material
Model: SHUVD02-05J-01
1. Product Introduction:
The series of cable materials is a UV cross-linked polyolefin cable material that is low smoke zero halogen (LSZH) and is independently developed and produced by SUNUA. Taking polyolefin resin material and polyolefin elastomer material as matrix material, through certain formula design and process design, compound high-efficiency halogen free flame retardant, functional materials and processing aids required for UV cross-linking through the specially designed production process. Thereby, a high-efficiency ultraviolet light cross-linked polyolefin cable material is prepared.
2. Implementation Standard: GB/T32129-2015 JB/T10436
This product's design, production, and use can fully meet the relevant standard requirements in GB/T32129 and JB/T10436, and meet its use requirements. The production process of this product is simple and does not require large-scale irradiation equipment and complex cooking processes. In the average production and extrusion process, suitable cross-linked polyolefin cable materials can be produced by ultraviolet light cross-linking equipment after irradiation.
3. Features and Uses
This Wire Jacket Material is a cross-linked polyolefin cable material, which has been adjusted to ultraviolet radiation (irradiation) to achieve the cross-linked cable material that meets the requirements. This product can be cross-linked under the irradiation of a wide range of ultraviolet light with different wavelengths. After absorbing the light energy of a specific wavelength, a series of polymerization reactions can be initiated by the generated free radicals under the irradiation of ultraviolet light, thereby forming a three-dimensional cross-linked polyolefin cable material with a mesh structure.
This Wire Jacket Material is recommended to be used in the insulation or sheath layer of cable materials with a wall thickness of no more than 1.2mm (maximum no more than 1.6mm).
4. Characteristics
This product is a low smoke zero halogen free flame retardant cable material. Through specific formula design and process design, it overcomes a series of technical obstacles and deficiencies in UV cross-linked polyolefin, and it ensures the excellent flame retardant performance of the cable material. It has the following main characteristics:
- Environmental Protection
- Halogen-Free
- Hygienic Safety
- Excellent Mechanical Properties
5. Extrusion process
This product has the same (or similar) extrusion process as the low-smoke halogen-free flame retardant polyolefin cable material;
barrel position | zone 1 | zone 2 | zone 3 | zone 4 | zone 5 | nose and mode |
temperature | 135℃ | 145℃ | 155℃ | 160℃ | 160℃ | 165℃ |
Note: Due to the different processing equipment, the plasticizing ability of the material is different, so in the initial production trial process, the temperature is only for reference, and the production speed is about 60% of the normal production speed for trial production.
6. Packaging, transportation and storage
Packing: N.W: 25kgbags with inner bag of plastic film moisture-proof bag and outer packing being made of kraft paper composite bag .
Transportation and storage: It should not be exposed to the sun and rain during transport. It should be stored in a clean, cool, dry and ventilated warehouse. It should be handled with care.
7.Shelf life : 6 months
