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):

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:What do you mean by grade 1, class two or class three in plastic?
Three grade material refers to the raw material has been used two times or more times, the processing of particles, and its elasticity, toughness and other aspects are not very good.
Q:Is plastic raw material rubber?
Raw materials are polymers of polymers such as polypropylene. Is generally from the fossil raw materials inside the extraction after polymerization together. A series of plastic refers to the resin as the main component, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials. To put it simply, the oil was extracted and finally made into plastic, rubber and plastic
Q:What is the hardness of PAEK+30%GF plastic material?
Polypropylene plastic (PP) hardness is Rockwell hardness 48. General plastics Rockwell hardness, Brinell hardness and Rockwell hardness measurement, not with Mohs hardness measurement. The hardness of nails is not measured, so it is difficult to compare with the data, I think the hardness should be quite.
Q:What are the heavy bags in the plastic material?
(polypropylene) English Name: Polypropylene, PP plastic concept, proportion polypropylene, also includes propylene and a small amount of ethylene copolymer. PP granular material is natural, cylindrical particles, smooth particles
Q:Characteristics of rigid polyurethane foam made of polyurethane raw material
Adhesive force: strong adhesive ability, and can be firmly bonded to concrete, masonry, wood, steel, asphalt, rubber and so on;Thermal conductivity: 0.017-0.022W/m.k, lower than rock wool, glass wool, polystyrene board, extruded panels and other building insulation materials;Hydrophobic property: hydrophobic rate 95% above;
Q:Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?
Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.
Q:What are the criteria for the classification of plastic materials at injection molding and extrusion?
Plastic material is injection molding or extrusion grade, there is no standard, but there is an applicable reference value, that is, the material "melt flow rate" value.
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:What kinds of plastic properties can be divided into thermal properties?
A. thermoplastic(a) polyvinyl chloride (PVC)Is the most widely used plastic varieties. Polyvinyl chloride resin is made from poly (vinyl chloride) monomer. According to the amount of plasticizer, it is divided into hard PVC and soft PVC. The former adds 30~70 phr of plasticizer <5 in 100 heavy resins, and the latter adds plasticizers.Physical properties: the relative density of hard PVC is 1.35 to 1.60, which is 1 / 5 of carbon steel; the relative density of soft PVC is 1.2 ~ 1.4.The water absorption rate of hard PVC is very low. The water absorption rate in long-term immersion in water is <0.5%; the soaking water is 24h, and the water absorption is 0.05%. The permeability of PVC is very low.The glass state temperature of PVC is 80~85 DEG C, the viscosity is 180 DEG C, the decomposition temperature is 240~260 DEG C (including stabilizer), and the brittleness temperature is -50 ~ -60 DEG C.The recommended temperature range of hard PVC is, in principle, maintained in terms of brittleness and glass temperature. If it is used above 50 degrees, necessary measures should be taken.The pure PVC, without stabilizers, begins to decompose at 150 C, releases hydrogen chloride, and further accelerates its decomposition. It decomposes faster than 180 DEG C. The polyvinyl chloride with the stabilizer decomposes the temperature to 240~260 degrees centigrade, but breaks down hydrogen chloride if used for 220 years. The material changes from dark grey to yellow brown, or even black. Therefore, in welding, we should try to avoid this phenomenon, the linear expansion coefficient of hard polyvinyl chloride is (5~6) X10-5 / DEG, 5-6 times larger than carbon steel. Therefore, when installing polyvinyl chloride pipes, expansion joints or bracing shall be installed to prevent deformation. When polyvinyl chloride is used as lining or bonding with other materials, the peeling phenomenon may be considered when heated.
Q:How are plastic products made? What is the raw material of plastics?
Plastic raw materials are particles, the production principle is similar
