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:

- Q: What are the raw materials of foam plastics and how do they come out?
- The foaming agents for epoxy resins are two types: physical foaming agents and chemical foaming agents. Physical foaming agents are mainly low boiling liquid, such as three chloro methane (F11), three chlorine, three fluorine ethane (F112), two chlorine, two fluorine methane (F12) and so on. By using the curing heat of the epoxy resin, the liquid with low boiling point is evaporated, and the gas is released, and the products are small in density and low in thermal conductivity. But fluorine hydrocarbons have a damaging effect on the atmosphere and are often used to spray foaming processes. According to the experts of China epoxy resin industry association, toluene and so on can be used as auxiliary foaming agent. In addition to foaming, it also acts as a curing reaction, a heat absorber and a diluent.
- Q: What is the difference between EPS plastic particles and PS? What materials are represented?
- EPS is a foaming agent that is used to make foam, which is the white foam that is packed in the TV and refrigerator.
- Q: How many kinds of plastic do you have?
- Special plasticsGenerally refers to a special function, can be used in aviation, aerospace and other special fields of plastic. Such as fluorine plastics and silicone, with outstanding resistance to high temperature, self-lubricating and other special functions, and enhance the plastic and foam plastic with high strength, high cushioning and other special properties, these plastics are in the category of special plastics.
- Q: What can recycled plastics do?
- Can replace some wooden products; can be used to make all kinds of plastic bags, barrels, pots, toys and other plastic products, living utensils. Recycled plastic granulator, plastic prospects, turn products (plastic particles) a wide, plastic enterprises demand, a medium-sized agricultural film factory, in need of more than 1000 tons of polyethylene particles, a medium-sized shoe factory in need of more than 2000 tons of PVC particles, smaller private enterprises, with particles in years more than 500 tons, so the plastic particles in a large gap, can not meet the demand, so the plastic manufacturers, sales of excellent, excellent benefits.
- Q: What are the plastic bags made of?
- Barrels are usually produced in HDPE, and as for plastic bags, these materials can be made, including polypropylene. Relatively soft is made of high pressure material, relatively hard bag is made of low pressure material, hard and quite, is PP do. Linear low density polyethylene has a strong tear resistance and is generally improved by adding a certain percentage to high pressure polyethylene. The requirements are not too high to add some recycled materials and should be appropriate to reduce the cost of filling masterbatch.
- Q: What are the main raw materials of plastic products?
- 2, and 372 organic glass welding good, made of two color plastic parts, and surface chromium plating, spray paint processing3, high impact, high heat resistance, flame retardant, enhanced, transparent and so on.4, liquidity is a little worse than HIPS, better than PMMA, PC and so on, good flexibility.Molding performance 1. amorphous material, medium mobility, moisture absorption, must be fully dry, surface requirements of the plastic parts must be prolonged preheating, drying 80-90 degrees, 3 hours2., should take high material temperature, high mold temperature, but the material temperature is too high, easy to decompose (decomposition temperature is >270 degrees). For the higher precision plastic parts, mold temperature should take 50-60 degrees, for high gloss, heat-resistant plastic parts, mold temperature should take 60-80 degrees
- Q: What type of raw material is used in plastic bags? The brightness is good. It blows out as bright as a mirror! That kind of transparency!
- High density polyethylene (LDPE) transparency, the equivalent number can reach about 90%, but the temperature should be controlled well, there is no general problem, that is, the cost is higher than other products
- Q: That kind of plastic bottle blows well
- PPEspecially the soft material, good toughness, non-toxic, high temperature resistant, often make catering appliance or other high-temperature product packaging; but the plasticity, processing difficulty, surface gloss and color processing, will be lighter, used to make disposable plastic bottles
- Q: What plastic material is resistant to high temperature?
- PPS is a kind of special engineering plastics with excellent comprehensive performance. Dimensional stability of PPS has excellent temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced and excellent physical and mechanical properties and excellent electrical properties and other characteristics, are widely used as structural polymer materials, by filling after modification, widely used in special engineering plastics. At the same time, it can be made into various functional films, coatings and composite materials. It has been successfully applied in the fields of electronics, electrical appliances, aeronautics and Astronautics, automobile transportation and so on. Domestic enterprises have actively developed and formed a certain production capacity, which changed the situation of relying solely on imports in the past. However, there are still some problems in China's PPS technology, such as low variety of products, high functional products, and urgent expansion of production capacity, which will be the focus of the next development of PPS.
- Q: What material do you need for plastic film? Do you use this material?
- Or LDPE (high pressure polyethylene). Or a mixture of the two. The bags made of two materials each have their own characteristics, and are chosen according to the purpose and performance of the products. Polyethylene is petrochemical products, prices vary according to crude oil and market conditions every day, at present LDPE (high pressure polyethylene) offer at 13500 yuan. HDPE (low pressure polyethylene) at 11000 yuan up and down.
