some of the main principles of the processing aid for processing

1, the role of the principle of PVC processing aids melt due to poor scalability, easily lead to melt broken; PVC melt relaxation slow, easily lead to the product surface rough, dull and shark skin and so on. Therefore, processing often requires the addition of PVC processing aids to improve the melt processing aids described above is the lack of processing performance can be improved resin additives, and its main role in three ways: to promote the molten resin to improve the rheological properties of the melt lubrication and promote the molten resin to give: PVC resin in the WSD PVC flame retardant  heated state, when the shear force under certain melt processing modifier first melted and adhered to the surface of the PVC resin particles, its compatibility with the resin and Its molecular weight, the viscosity of PVC and increasing the friction, and thus the shear stress and the effective heat transfer to the PVC resin, melt rheology improving the acceleration performance of the molten PVC: PVC has a melt strength is poor, poor ductility, and melt fracture shortcomings, and to improve the melt processing of said modifier rheology. Its mechanism of action: Increase the PVC melt viscoelasticity, thus improving the die swell and melt strength gives improved lubricity: PVC processing modifier is compatible with the first portion of the melt, plays the role of promoting the melt; but not with PVC Compatible part WSD Polyethylene wax  migrate to the outside of the molten resin system, thereby improving the releasability of the copolymer 2, a conventional processing modifier ACR ACR methyl methacrylate and acrylate, and styrene monomers. In addition to be used as a processing aid, it can also be used as impact modifiers. PVC plastic window profiles or generally used ACR201 ACR401, in an amount of 1.5-3 parts of a modified impact modifier polymer content is important to improve the impact resistance, PVC resin is a non-polar high crystallinity there is a strong interaction between the oligomer molecule, is a hard and brittle material; low impact strength. After the addition of impact modifiers, elastomeric impact modifier particles can be raised to reduce the total stress crazing and  WSD zinc stearate its particle deformation and shear band and prevent crazing expansion and growth, absorb the impact of the transmission of the body material able to achieve the purpose of impact. Small particle modifier to facilitate increasing the number of unit weight or unit volume of a modifier to increase the effective volume fraction, thereby enhancing the ability of stress dispersion. Currently used widely for organic impact modifier.

There are many kinds of plastic processing aid methods

About plastic extrusion, injection molding, blow molding, rotational molding, casting, dip and other plastic molding process, depending on the specific choice of materials and products, the advantages and disadvantages of hard to say.
  Here I am with PE plastic processing methods simply lower, PE available a wide manufacturing different processing method. As the main raw material ethylene, propylene, 1 - butene, hexene copolymer, under the action of a catalyst, using a slurry polymerization or gas phase polymerization process, the polymer obtained by flash separation, drying, granulation, etc. processes, was
Uniform particles have finished. Including such sheet extrusion, film extrusion, pipe or profile extrusion, blow WSD Plastic impact modifier  molding, injection molding and rotational molding. Extrusion: grade for extrusion production generally has a melt index of less than 1 and the width to wide MWD. In the process, the availability of suitable MI low melt strength. Broader MWD is more suitable for extrusion grades, because they have a higher production speed, lower the die pressure and melt fracture reduction trend. There are many PE extrusion applications, such as wires, cables, hoses, tubes and profiles. Pipes for natural gas applications ranging from a small section of yellow tube to 48in diameter thick-walled clarinet for industrial and municipal pipes. Alternative to large diameter hollow wall  WSD zinc stearate made of concrete pipe used as rainwater drains and other sewer pipelines rapidly.
Sheet and thermoforming: Many large picnic-type freezer thermoforming lining is made of PE, with toughness, light weight and durability. Other sheet and thermoformed products include fenders, tank linings, disc bowl guard, transport boxes and cans. The rapid growth of a mass-sheet applications are mulch or bottom in the village, which is based MDPE with toughness, chemical resistance and impermeability. Blow: These range from equipment bleach, oil, detergent, milk and a bottle of distilled water into WSD PVC stabilizer  a large refrigerator, car fuel tank and the canister. Blow molding grade characteristic indicators, such as melt strength, ES-CR and toughness, and the sheet for thermoforming applications level
Similar, it can be used with similar grade.

Use the principle of PVC processing aid

In industrial production, in order to improve production processes, improve product quality and yield, or to give the product of a specific application performance by adding auxiliary chemicals. Also known as the additive. However, as an important component of the product matrix, the product shape, structure, performance of large doses have a significant impact of additional material, generally not included in the scope of aid. Additives wide range of applications, usually re-dubbed the role of one pack stabilizer  object names, such as polymeric additives, water treatment, metal surface treatment agent. There are some common additive selection considerations, such as: ① use of the additive requirements. Additives appearance, odor, contamination resistance, durability, electrical properties, weather resistance and so the use of direct impact products. ② processing conditions additives adaptability. ③ durability additive. Loss additive mainly through evaporation, extraction and migration pathway 3, the species must be selected appropriately according to the environment and the article processing conditions. ④ compatibility with polymer additives. Comprises mixing in impact resistance and stability of each may be a problem between them. ⑤ additive toxicity. Food and drug packaging materials, water pipe, medical equipment and other polymer materials, products, their health mainly depends on additives used. ⑥ synergistic and additive effect between proposition. If chosen appropriately, the mutually reinforcing, and can reduce the total amount of additives. The use of additives principles:
The current provisions of the international system can be divided into two, one is to allow the use of additives "exhaustive" "whitelist" lists, and the other is listed aids disabled "disabled list." After years of practice, "disabled list" to be found there is a big drawback: the lack of new substances binding. Plastic profiles Promoters
Additives a plastic profiles: impact modifiers, such as the production of plastic profiles without impact modifier, plastic profiles will be very brittle, a little collision, easily broken. Commonly  chromium oxide Titanium dioxide rutile used in the production of plastic profiles impact modifier modifier consists of the following three categories: chlorinated polyethylene, polyacrylate, ethylene - vinyl acetate copolymer. Plastics Additives two sections: heat stabilizers plastic profiles are heat-sensitive plastic, so plastic profile production machining, heat stabilizers is essential. Metal heat stabilizers in PVC can absorb decomposition of HCL, it can slow down the rate of decomposition of plastics and extended decomposition time, the production of plastic profiles for the most commonly used compound lead salt, high-efficiency thermal stability, low prices. Plastics Additives three  sections: the main processing aid processing aids plastic molding  PVC lubricants process in order to improve the performance improvements and the development of a class of additives. Plastic profile processing temperature and decomposition temperature relatively close, poor mobility, easy to stick on the device coking, and therefore the production of plastic profiles need a certain amount of processing aid to overcome the defects of plastic profiles itself.
