influence of plastic processing aid materials

Although the material is very common plastics processing generally, but supplies are essential in our lives. The growth rate of
China's plastics processing industry is extremely fast, especially closer to modernization today. Plastics processing industry in a
very rapid rapid development. Now a lot of WSD plastic additive  material wood and metal has its drawbacks and limitations, they produce slow, costly,
and now a lot of weight disadvantages such as wood and iron products and parts have been replaced by plastic products, such as we
often see articles toothbrushes, nozzles, cups, sandals, etc. are made of plastic. It can be said almost unlimited capacity to
replace plastic.
As you know, a lot of things have plastic processing aid expansion and contraction characteristics, when something temperature
increases his larger expansion of the molecular structure, its outward expansion of larger organizations, we will let him certain
items heating swelling larger and be recorded, and then cooled to let him reduce some objects and records can be larger expansion
gap between the two objects in and out of the objects referred to as shrinkage. Plastic is so objects. According to the water-
absorbent plastics material is divided into two types of processing is divided into two types: the first one is the comparative
water-absorbing plastic, the second is  WSD plastic processing aid non-absorbent plastics. Plastic is easy to absorb water must be pre-processed was dry,
plastic processing aid for wastewater treatment, if the problem does not occur in the processing of the processing, the processing
time since the evaporation of water causes foaming of plastic, the payment of the low viscosity, resulting in forming Poor quality
of plastic products, so that the plastic has a significant influence on the drainage of molded plastic. If done in a plastic air
drying time is too long, it may absorb water again, be the result of water discharge through the plastic work. So those plastic
drainage has been done drying process must protect their drying plastics processing in accordance with WSD Titanium dioxide rutile  the chemical composition of
the material can be divided into: thermoplastics and thermosetting plastics. In order to distinguish the specific purpose, there
are many branches of two plastic names they use are different performance, thermoplastic polyvinyl chloride plastic, polycarbonate
cool, two questions need to plastic molding is not completely the same, in front of a species of mold is to first heat, followed by
cooling the mold you need. So be sure to have on the performance of plastic-depth understanding.

plastic processing aid described in detail

Propylene can become non-polar and polar materials to enhance adhesion and material compatibility bridge. Add a maleic anhydride
grafted polypropylene in the production of filled polypropylene, can greatly improve the affinity and polypropylene filler and
filler dispersion. It can effectively enhance the PVC flame retardant  dispersion of the filler in polypropylene to improve the tensile and impact
strength of filled polypropylene. Typical applications include maleic anhydride-grafted polypropylene: plastic processing aid
compatible inorganic reinforcing material (glass fiber) and filler material (calcium carbonate, talc, etc.) and polypropylene
coupling between the polypropylene / nylon alloys improving agent of polypropylene with a polar material (metal, nylon, etc.)
adhesion. HR tear the rubber resin added can  Polyethylene wax significantly increase the hardness of the rubber, aging resistance, abrasion
resistance, tear strength, tensile strength, and kneaded with an easy processing, easy and good coloring thermoplastic,
electrically insulating properties. It includes: 1, compared with one-component sealant, plastic processing aid faster overall
curing, the electronic module can be encapsulated and the stearic acid larger objects (depth greater than 7mm) 2, compared with the bicomponent
lower cost. 3, compared with epoxy resin, with excellent resistance to high temperature, anti-aging and anti-ultraviolet function.
Potting electronic modules, LED display, the pixels, backlight, and other electronic components: Typical uses.

a type of plastic processing aid analysis

plastic processing aid according to different molecular weight, and have different functions. Processing aid ACR 50-150 10,000 molecular weight processing aids are widely used for general article PVC flame retardant  having a core - shell structure of the elastic polymer, the core-shell impact modifier emulsion was ACR production technology core. In the continuous research and development of the global impact modifier ACR, the foreign ACR impact modifier has been enhanced on the basis of the traditional techniques, particularly aspects of particle size control and continuous production. China's major manufacturers early ACR impact modifier produced using seed method, batch aluminium stearate  emulsion polymerization production processes and devices equipped with a small, poor performance and product quality control fluctuations, impact product performance and greater foreign gap, the same low productivity, small batches. plastic processing aid development and testing of a large number of companies to achieve a one-step control of latex particle size, and to achieve low-temperature continuous emulsion polymerization process, greatly improving the efficiency of production, production plant expansion  Aluminum hydroxide through. In terms of the production process recipe uses a third, fourth functional monomers such as acrylic rubber performance in terms of both the impact and tensile greatly improved product performance reached the international advanced level.
