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:What are the main raw materials used in plastic products?
PS plastic (polystyrene) English Name: PolystyreneSpecific gravity: 1.05 g / cubic centimeter molding shrinkage: 0.6-0.8% molding temperature: 170-250 DEG C drying conditions: ---The material properties of electrical insulation (especially high-frequency insulation) excellent, colorless and transparent, light transmittance after organic glass, color of water resistance, good chemical stability and strength. In general, but the crisp, easy to produce stress cracking, no resistance to benzene. Gasoline and other organic solvents. Suitable for making insulating transparent ornament and. Chemical equipment. Optical instruments and other parts.Molding performance 1. amorphous material, moisture absorption is small, not to be fully dry, not easy to break down, but the coefficient of thermal expansion is large, easy to produce internal stress. Better liquidity, can be used screw or plunger injection molding machine2., should use high material temperature, high mold temperature, low injection pressure, extended injection time, is conducive to reducing internal stress, prevent shrinkage, deformation3., can be used in various forms of gate, gate and plastic parts arc connection, so as not to go to the gate when damaged plastic parts. Stripping large slope, top out even. Plastic parts wall thickness uniform, preferably without insert, if inserts should be preheated
Q:Can I make tea with a plastic cup?
The plastic cups sold in the mall are qualified and unqualified. As consumers, we can only make a simple judgement from the surface of the goods. For example, look at the trademarks, factory name, site, telephone, raw materials, texture, certificate and so on
Q:How much is plastic PP5 resistant to cold?
Ordinary homopolymer PP has higher heat resistance, but when it reaches -20 degrees of low temperature, it will not stand, easy to brittle.
Q:Plastic molding is what to do, how the process?
The plastic molding is various forms (such as powder, granules, solution and dispersion) of plastic products or parts required for the shape of. Simply put, it's the plastic process that produces plastic or plastic parts.
Q:What is the white fine plastic rope hanging with a tag on it?
Introduction: as the name suggests, nylon rope is made of nylon material, rope, also known as release cable, anti-static sampling rope. Niron (Nylon) chemistry called polyamide, English name Polymide (referred to as PA). Nylon is widely used and can be made into hard and flexible products of different quality.
Q:What are the hazards of plastic oiler
Fire easily, easily bitten by rats, cold oil solidification also fell out.
Q:Is there a difference between recycled plastics and new ones?
Polyethylene: the performance of polyethylene has decreased after regeneration, the color yellow. After several extrusion, the viscosity of HDPE decreases, and the viscosity of LDPE increases.Polypropylene: when regenerated at one time, the color is almost constant, and the melt index rises. More than two times the color increased, the melt index is still rising. After regeneration, breaking strength and elongation decreased, but no problems in use.
Q:The lid of the vacuum cup is plastic. Will drinking water affect it?
Plastic points are many, there is no harm to his face and asked to put into plastic, ceramic, glass or metal, the answer is the same, so can not be generalized;
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 type of plastics do you have?
At the beginning of the heating, the resin molecules are linear in structure and still have plasticity of thermoplastics. When continue heating, linear molecular chain is formed between the chemical bond (i.e., molecular cross-linking) were net shape structure, when the temperature reaches a certain value, molecules into the body structure, the resin into both melt and dissolve the state. Repeated heating does not soften any longer and is no longer plastic.
