Halogen Free flame retardant:
1. Applications and cable specifications:
General type. Used as cross-likable low smoke halogen free insulation and jacket for electronic wires, cotton coverd wire for construction. Work temperature: -40 to 125 degree C .
2. Description:
Silane crosslinkable low smoke halogen free POE compound, based on POE resin, is produced and pelletized by special technology, adding flame retardant, initiator, crosslinking agent and other special additives. This compound is composed of A materials and B materials, when it is used, please mix the A and B in the proportion of 97:3. This compound has advantage of excellent properties, processing easily, and excellent physical properties, meeting JB/T 10436-2004 standard.
3. Processing:
Equipment: it is recommended that this compound should be processed by professional screw for halogen free compound, with compression ratio of 1.2 to 1.5 (L:D should be 25 to 18). If you use PVC extruder, the speed should be lower and focus on cooling.
The following temperature(degree C) profile of extruder is recommended (temperature here is only for reference, and it will be different according to different extruder and temperature controlling equipment):
Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
Temperature | 110 | 140 | 160 | 160 | 165 | 170 |
Method of application:
(1) When you use this product, please mix A and B before put into the hopper. If you need color, the cable factory can use the polyvinylene masterbatch. The material should be used up after it opened in 8 hours and the rest can be resealed and usable within 24 hours.
(2) The extruder should be cleaned with PVC material after stopping, (It is preferable if you can take apart the screws to clean.)
(3) The silane crosslinkable LSZH compound should not be stayed in the extruder for a long time .If it stayed for long time, it will pre-crosslink after open the machine, which will make lumps in the surface of cable. It need to be discharged all the pre cross-linker, and then produce the cable properly.
(4) To ensure the safety and fully of the cross-linking, when immersed the compound into the hot water or steam, please calculate the cross-linking time based on the terms of more than 85℃, 8h/mm thickness cross-linking speed.
(5) At room temperature, the degree of crosslinking can also meet requirements after 7-10 days. The specific time can be different according to the temperature and humidity.
Note:
(1) Transportation: avoid direct sunlight and weathering and machine damage
(2) Convey: discharge softly, put off softly, avoid from the bursting by the stressed with the aluminum-plastic Bag.
(3) Storage: it can not be landing stack. It should be put on the pallet in the clean dry storage.
(4) Keep dry: When the material used, it must not be contained the outer water. Otherwise, it will seriously pre-crosslink.
(5) Quality guarantee period: 6 months after manufacturing.
4. Storage and transport:
Packaging:25kg/bag, Aluminum foil and PE film bag inside, and Kraft bag outside.
Storage and transport: Avoiding in direct sunlight and weathering. The storage should be clean, cool, dry, and ventilated.

- Q:How many kinds of plastic raw materials are there? How to distinguish them?
- Plastic with its superior performance gradually replaced many has been used for decades, hundreds of years of materials and utensils, becoming an indispensable assistant. Plastic and metal in hard wood, light transparent glass ceramic, corrosion resistance, rubber elasticity and toughness in a body. Therefore, in addition to daily necessities, plastic more widely used in aerospace, medical equipment, petroleum chemical industry, machinery manufacturing, defense, construction and other industries.
- Q:Low pressure plastic raw materials in the process of blowing the two sides of the fold, how to deal with?
- Blow up ratio of transverse expansion ratio of the film, is actually on the orientation of the transverse tensile film, tension will have a certain degree of plastic molecules, the blowing ratio is increased, thereby improve the lateral strength of thin films.
- Q:What is the plastic basin made of?
- Machines generally use injection molding machines, raw materials using PP and PE, the raw material price of more than 10000 a meal, and some can be used to feed prices at around 5000. Equipment price depends on your size, small injection molding machine plus two or three sets of film, about one hundred thousand on it.
- Q:How to make plastic raw materials?
- Cracking is in the process of petrochemical production, which is higher than the cracking temperature (700 DEG to 800 DEG C, sometimes even more than 1000 degrees Celsius), making oil fractionation products (including petroleum gas) long chain hydrocarbon in the fracture process into short chain hydrocarbons such as ethylene and propylene.Cracking is a much deeper cracking. The chemical process of oil cracking is more complex, generated by pyrolysis gas is a mixture of complex components, in addition to the main products of ethylene, and propylene, isobutene and methane, ethane, butane, acetylene, hydrogen sulfide and carbon oxides. After the pyrolysis gas is purified and separated, the basic organic chemical materials such as ethylene and propylene can be obtained with the required purity. At present, petroleum cracking has become the main method of producing ethylene.
- Q:I'd like to know what PP plastic material is PP plastic raw materials cleaning can not use ultrasonic cleaning machine to wash it?
- After research, "ultrasonic cleaning machine" function is that as long as the liquid can be immersed in the sound field, the product exists in the cleaning role, and the cleaning speed, high quality. Especially for PP plastic raw materials, under the action of ultrasound, it takes only 5-10 minutes to complete. The speed is several times as many as that of the traditional method, and the cleanliness is also high.
- Q:Can PE material be used as food grade plastic?
- Plastic film PE the main consumption areas, because of its more and more used in consumption and transportation, the development of the relationship between demand and the overall economic situation is bigger, basically maintain a slightly higher than the national GDP growth, the growth momentum of stable existence of rigid demand. From the flexible packaging film production statistics, since 2006, the average increase rate of 13%, but also confirms the steady growth of plastic film. Another important consumption area of polyethylene is plastic pipe, and its output increases with the pace of urbanization in China, and the increase of municipal pipeline construction projects is increasing. In the next few years, the municipal water supply and drainage, gas pipelines, and urban underground power, communication, sheathing and pipelines will continue to be the focus of development in recent years.
- Q:Plastic raw materials are granular, why not powder?
- Who says plastic raw materials are granular?.
- Q:What is the material of plastic flat screen?
- It is made of hot spraying and cold fixing. It has the characteristics of wear resistance, corrosion resistance, toughness and so on. It can be used as a substitute for wire. The utility model has the advantages of corrosion resistance, light weight, long service life, no poison, no smell and good transparency.
- Q:What are the raw materials for vest plastic bags?
- Low density polyethylene (PE), or LDPE, is the most widely used plastic packaging and printing industry in many countries. The specific gravity is 0.92 ~ 0.93, and can float in water. Low crystallinity (60%), under the pressure of 1000 ~ 3000kg/C square meters of bulk polymerization of high pressure polyethylene. At 23 degrees centigrade, the density is about 0.92. It is difficult to roll forming and is suitable for tubular films. Applicable to food packaging, fiber packaging, daily necessities packaging.
- Q:How to test plastic raw materials?
- Contrast the appearance quality of raw materials, separately open 1~2 bags, take out a little plastic particles, contrast the size and color of the plastic particles in each bag. And compare the same batch of plastic particles with the previous batch. There were no obvious differences in the color and graininess of the raw material particles in different packaging bags and batches
