What is the tensile strength of Paste PVC P440?
PVC P440 is paste polyvinyl chloride. But, it is quite challenging to mention
the exact tensile strength of it without particular data from its supplier or related standard
test reports. The tensile strength of paste PVC usually varies widely depending on the
formulation, additives, and manufacturing processes. Common paste PVC materials may have tensile
strengths from 10 - 30 MPa. But maybe not for P440.
If it's formulated for specific
high-mechanical-strength applications (like certain industrial coatings or molding compounds),
it may have a higher tensile strength, potentially within the upper range of the common range,
or even higher values with new formulations. If, however, it's for applications that are less
stringent or more elastic, the tensile strength could be on the lower end. The tensile strength
of Paste PVC P440 is determine through standard tensile strength tests according to ASTM D638 or
ISO 527 testing methods and you should refer to the manufacturer's technical data sheet to
obtain this value.
What is the chemical composition of Paste PVC P440?
Paste PVC P440 (based paste PVC resin)
It is mainly composed of a
steam of polyvinyl chloride. Polyvinyl chloride (PVC) is a polymer derived from the
polymerization of vinyl chloride monomers. It has a linear molecular structure consisting of
-CH2-CHCl- repeating unit. This backbone imparts the basic physical and chemical properties to
the material, including some degree of mechanical strength. Taste PVC P440 D-Page may use
different additives besides the PVC polymer. Plasticizers are often added. It makes the PVC
more flexible and plumping it. They do so by lowering the intermolecular forces among the PVC
chains and enabling them to move more freely. Another very common additive are stabilizers. They
further prevent degradation of the PVC due to heat, light, or oxidation during processing and
use. Some metal - based stabilizers, for example, can catch harmful radicals capable of breaking
apart the PVC structure. There may also be fillers. These fillers can enhance the hardness,
modify the other properties, and reduce the cost of the final product of Paste PVC P440.
Calcium carbonate is one of the most common fillers. Color pigments are also added to customize
the color of the material for specialized applications.
What are the applications of Paste PVC P440?
What is paste PVC P440? It is most commonly used to make artificial
leather. Paste PVC, which is spreadable, can be used to coat a fabric base for a leather - like
material. It is used extensively as a form of upholstery in the furniture industry, allowing
customers to get an authentic-looking alternative to genuine leather that is generally less
expensive, relatively durable, and featuring a wide range of textures and colors.
It is
also used to make floor coverings. The paste PVC can be made into vinyl flooring sheets or
tiles. The floorings are found in many commercial and residential areas because of its water -
resistance, easy - cleaning property and relatively long life period. They can also replicate
the look of natural materials such as wood or stone, enhancing the visual appeal of the room.
Paste PVC P440 can be coated onto any substrate including, but not limited to, the
coating industry. For instance, it will react on metal or plastic objects to give a thin coat of
protection. This coat can help improve the corrosion resistance of metal products and scratch -
resistance of plastic products, so as to prolong their service life.
What is the density of Paste PVC P440?
Paste PVC P440 density may vary on a few elements. Normally, the density of paste
PVC has an average of about 1.3 - 1.4 g/cm³.
For Paste PVC P440 in particular, due to
the lack of more detailed manufacturer - provided data or specific testing undertaken on a
specific batch of production, the exact value is hard to come by. But without that level of
precision, it is safe to assume it is within the general density range of paste PVC materials.
The density will be influenced by factors such as the type and amount of plasticisers present in
the formulation. Paste PVC is modified by adding plasticizers so that it can be made flexible
and soft as required. If more plasticizers are added, it can have a small impact on the density
which is usually going down somewhat. The type of polymers and additives in Paste PVC P440
may also make a difference. Additional differences in density can arise from the use of
different polymer types (e.g. molecular weight and structure), fillers, and stabilizers. So, we
will generally round it something close to the common paste PVC density values, but to get a
precise density value, it will be better to check it in the product data sheet from the
manufacturer or conduct direct density measuring methods as the pycnometer method.
What is the melting point of Paste PVC P440?
Paste PVC P 440은 폴리염화비닐의 일종이다. PVC's melting point depends on various factors
such as its formulation, additives and molecular weight.
The melting range surface is
relatively constant at about 160 - 180 degrees for Paste PVC P440. PVC is a thermoplastic
polymer in general. Heated, it changes from solid to viscous liquid at its melting point.
it is relatively easier to process due to its comparatively lower melting point, hence
its wide applicability. For example, Paste PVC P440 has a melting range that makes it suitable
for plugging and molding in various forms during processing. The melting behavior of Paste PVC
P440 can also be modified using various additives. Plasticizers, for example, can decrease the
melting point, increasing flexibility and workability of the material. This allows manufacturers
to make a variety of products with Paste PVC P440 in a certain temperature threshold for melting
and processing.
What is the viscosity of Paste PVC P440?
There are factors that affect the viscosity of Paste PVC P440.
For paste
PVC grades such as P440, viscosity is critical and thus forms part of the processing
characteristics. Overall, Paste PVC P440 viscosity is typically engineered to fall within a
specific range ideal for processes like coating, dipping, or rotational molding.
For
coating application, a relatively lower - medium viscosity desired for good flow and even
coverage on the substrate. As for the viscosity, if it is high, it can cause problems, such as
uneven coating thickness and difficulty in spreading the paste. Conversely, if it is too low the
paste will run out or sag, also with low – quality coatings. Instead, the viscosity of the PVC
paste has to be controlled to allow the paste to evenly coat the mold walls as the mold rotates.
However, the viscosity of Paste PVC P440 is optimized for such applications to ensure the proper
filling of molds and the formation of the final product with a uniform wall thickness.
However, it is impossible to create an exact viscosity without specific data from the
manufacturer or testing under defined conditions. However, it is designed on the basis of the
needs of a process used more commonly in paste - type PVC applications.
What is the curing time of Paste PVC P440?
Paste PVC P440 can have a considerably different curing time, owing to a number
of reasons.
First things first: temperature. If the environment is of relatively high -
temperature, about 150 - 200 degrees Celsius, the curing can thus be quite fast, only taking 10
- 30 minutes. Higher temperatures increase the rate of the chemical reactions that go into
curing, including the cross - linking of polymers.
Second, the thickness of PVC paste
layer is important. It will cure faster if it is in a smaller/thinner layer. A thin film of
Paste PVC P440 has an average powder that can cure in 15 - 20 minutes depending on the heating
condition the powder is placed. But for a thick layer, heat transfer is more difficult and it
may take 40 - 60 minutes or more for the inner part of the thick layer to react.
The third factor is the presence of curing agents and their concentration. By using
effective and appropriately - dosed curing agents in the composition, curing time may be
reduced. However, with insufficient curing agent concentration, the curing process will be slow,
in which case the curing process can take more than an hour. Not having these factors
specifically defined makes it rather difficult to provide you with an accurate curing time but
it is between 10 minutes to over an hour in general.
What is the shelf life of Paste PVC P440?
Paste PVC P440 shelf life can depend on conditions. Under typical
storage conditions, which usually means storing in a cool, dry place away from the sun and heat,
it typically has a shelf life of about 6 to 12 months.
Too humid storage can result in
problems with clumping or consistency changes of the paste over time, and it reduces its generic
usability time which can be a pain in the ass. Warm temperatures may speed up the chemical
reactions in the paste and degrade its quality faster. However, whether it’s proper packaging,
that also matters a lot. If the Paste PVC P440 is tightly sealed in original packaging, this
reasonably helps with keeping it in its best shape longer. Once the pack is open, they can be
affected in performance from air and contaminants, and the shelf life will be reduced even more.
Manufacturers typically include precise instructions about storage and shelf life within the
product label or technical documentation. (Paste PVC (P440)Paste PVC)
What is the price of Paste PVC P440 per kilogram?
Paste PVC P440 price per kg range can depend on plenty of these factors. Market
conditions also have an impact. If supply and demand are stable, prices may be quite steady.
That being said, a sudden spike in demand due to the boom of the plastic - coating or flexible -
packaging industries, which are both very reliant on this type of PVC, could raise the price.
Conversely, an oversupply scenario, perhaps due to new production facilities being brought
online, may see prices come down.
Location also affects price. Gas closer to sources of
production may be cheaper, as the transportation costs are lower. Alternatively, in distant
regions from the manufacturing facilities, shipping costs are included on top of the base price.
The commercial price of Paste PVC P440 has been approximately between $2 to $5 per
kilogram in recent times. But that is just a ballpark figure. Please check with PVC suppliers or
industry reports, or online marketplaces dealing with chemical raw materials for the most
accurate and up - to - date price. These include immediate pricing data based on current market
conditions.
