II.   Product description

Low-smoke, low-halogen and flame retardantPVC compound for cables and wires, based on PVC resin, is made into granula byspecial technology with adding special plasticizer, stabilizing agent, flameretardant, smoke suppressant, HCL absorber and other special agents. Thecompound has well performance of flame retardant. It has low smoke and lowburst size of HCL when burning. The produced wires and cables have 60% lighttransmittance. The products meet various special requirements, UV stable,environment friend (RoHs, REACH, PAHs, chlorinated alkanes free,  phthalate free, and etc.), sub-shine and fogsurface, rodent-repellent, termite-repellent, and etc.

III.  Processing

It is recommended that compound should beprocessed with common extruder having a minimum L/D ratio of 20. Non-specialrequirements of equipment and processing are needed.

The following temperature(℃)profile of extruder is recommended:

Q:Why can't we discard plastic products at will?
HDPE (high density polyethylene), used in the production of bottles, bath products, food plastic bags, but also the production of wine, resistant to high temperature of 110 degrees. It can be reused, but it can easily cause bacteria. Can be reused after careful cleaning, but these containers are usually not clean, residual original cleaning supplies, become a hotbed of bacteria, you'd better not recycle
Q:Can plastics be recycled?
According to the thermal properties of plastics can be divided into two categories, one is thermosetting plastics, thermosetting plastics is cured or insoluble in heat or other conditions (melting) properties of plastic, such as phenolic epoxy plastics.
Q:How do you glue a broken plastic basin?
Find you a soft plastic, burn it, drop the drop of plastic in the dew place!!
Q:What is the low temperature resistance of plastic PS?
PS plastic is polystyrene, and the brittleness temperature is 30 DEG C, therefore, PS plastic can be used at 20.
Q:What glue does the plastic product stick with?
502 glue for porous absorbent material and then, for iron and steel, nonferrous metals, rubber, leather, plastics, ceramics, wood, non-ferrous metals, non metals ceramics, glass and flexible materials such as rubber, leather, soft and hard plastic or their mutual adhesion, but of polyethylene, polypropylene, Teflon ethylene and other hard bonding materials, the surface through special treatment, in order to bond. Widely used in electrical appliances, meters, machinery, electronics, light instruments, medical, light industry, civil and so on.
Q:What are the materials for plastic bottles?
There are many ways of making polyethylene, the most common of which is the polymerization of ethylene at temperatures of 200~300 C and 1000~2000 atm. In polyethylene, no other substance is doped. This low density polyethylene obtained, soft texture, for sunlight, air, water and chemical reagents, have high stability, so no external stabilizer, plasticizer, stabilizer and plasticizer are mostly toxic or highly toxic.
Q:Can a plastic bowl be used safely?
Opinions and suggestions: in the purchase of plastic bowls, we must choose to meet the national standards of food grade plastic made by the cup. In all the materials of the bowl, the glass bowl is the most healthy, glass surface smooth, easy to clean, bacteria and dirt are not easy to breed in the cup wall, so people use glass bowl is the healthiest and safest. It is best to use a bowl, the bowl with more safety, and good processing technology, wood bowl is also a good choice.
Q:What can soften a hardened plastic?
Thermoplastic structures are linear structures that soften or melt when heated and are plastically made into a definite shape and hardened after cooling. After heating to a certain extent, it softens again and hardens again after cooling. This process can be repeated many times. For example, most plastics, such as PE, PP, PVC, PPR and PS, belong to thermoplastic plastics. Thermoplastic molding process is relatively simple, can be continuous production, and has a high mechanical strength, so the development of very fast.
Q:What products are plastic extrusion?
Extrusion plastic products are as follows:One, PVC hard tubeTwo, PVC hoseThree polyolefin pipesFour polycarbonate (PC) tubeFive, polystyreneSix polypropyleneSeven, ABS sheet and boardEight, PPR pipe
Q:Advantages and disadvantages of plastics
The plastic can be processed into various shapes according to the requirement of use, and the processing technology is simple, and the machine is suitable for large-scale production by mechanization.
