    How to Buy PVC Foam Board Correctly?


    The use of PVC foam board is very wide. Kitchen and bathroom furniture, car and boat partitions, bus flooring, screen printing and painting, advertising engraving, etc. will use PVC foam board. There are many popular PVC foam boards in the market. If you buy poor quality PVC foam board, then we process the finished product into a substandard product, which will bring economic losses to the enterprise. How to correctly go to buy quality PVC foam board?

    Observe the surface of the foam board

    1. Look at the color of the surface of the PVC foam board. If the PVC foam board surface color yellowing, or impure color with other miscellaneous colors, then the foam board in the formula must be a problem, or the production process is not. If used for advertising printing, the effect of printing out will be greatly reduced. Therefore, be sure to choose pure color, no color difference of PVC foam board.

    2. observe the cross-section of the PVC foam board has no air holes. Normal PVC foam board cross-section is uniform and dense tiny voids in the honeycomb. If the cross-section of the PVC foam board has large pores, then the foaming of this foam board is certainly not uniform. This is a poor production process. It will also produce bubble holes in the inner part of the board, that is, in the middle. Then, the force of this poor quality foam board will not be uniform, it is easy to make a place deformation or fracture.

    3. PVC foam board surface has more mechanical patterns. The more shallow and inconspicuous the mechanical pattern, the better the product.

    Smell

    The quality of PVC foam board should have no smell. If you smell a very pungent smell with your nose, it means that the board contains environmentally unfriendly substances, try not to use it.

    Tactile sensation

    1. Feel the surface hardness of the PVC foam board. If used for furniture production and other surface requirements are high, it should be difficult to scratch the mark with a fingernail. 3.2.

    2. Carefully touch the surface of the plate. Whether it is flat. There are no fine lines.

    Inspection

    1. Measure the thickness of the eight PVC foam sheets. Because the uneven thickness of PVC foam board will cause trouble to our secondary addition, such as the wrong size in some places. Therefore, we must measure the thickness of its eight parts is not the same, which eight parts? The four corners plus the middle part of the four sides.

    2. Take the sample to fall. Easy to break is generally a high calcium product. Of course, to meet your requirements if the price is right is possible.

    3. Take the sample and step on the side of the plate with your foot to see if it can be cracked. Or the elongation at break after cracking.

    4. The direct way to judge the degree of weathering is to get a high temperature and high light place for a few days to see the rate of change of the surface, but too waste of time.

    The above methods are only some sensory identification of the product, to facilitate our rapid identification of the market's diverse products. We are a PVC foam board supplier, please feel free to contact us if you need them!

    Common Problems of PVC Foam Board


    PVC foam board is widely used in daily life, PVC foam board manufacturers in the process of processing and production often have a variety of problems, the following we discuss and analyze the common problems of PVC foam board.


    PVC foam board outside the slip too much

    The precipitation will become serious, manifested in the structure of the mold and the surface of the plate outside the slip of the precipitation will also be manifested in some individual phenomenon on the surface of the plate irregular movement back and forth.


    PVC foam board outer slip is not enough

    Extruder 5 temperature is not easy to control, easy to heat up, resulting in high temperature of the merging core, the middle of the board out of large bubbles, string bubbles, yellowing and other problems, the surface of the board is not smooth.


    Insufficient inner slip of PVC foam board

    The plate surface is difficult to control the thickness, manifested as the plate is thick in the middle and thin on both sides; too much internal slip, easy to appear the phenomenon of high temperature of the merging core.


    PVC foam board surface yellowing

    Reason analysis: barrel, mold temperature is high, lubricant does not match well, the thickness of the board is too thick, yellow issued hot core layer slow heat dissipation, and the stability of the stabilizer also has a relationship.

    Solution: Properly reduce the mold temperature, choose efficient lubricant and adjust the lubrication with the thick board to reduce the amount of yellow hair to increase the amount of white hair, choose better thermal stability of the stabilizer.


    PVC foam board surface bending

    Cause analysis: uneven material flow or cooling is not in place, the factors that cause uneven material flow are generally large traction fluctuations or unbalanced internal and external lubrication in the formula.

    Solution: Check whether the cooling water circuit is smooth, so that the board surface is evenly cooled in place, check the traction machine to make its traction speed stable; adjust the amount of lubricant to make the lubrication balance, the current is stable.


    Cross-sectional bubble holes or bubble layering

    Cause analysis: can be attributed to a point, that is, the melt strength is not enough. Mainly because of excessive foaming agent or foam regulator is not enough, the ratio of the two is not coordinated, or foam regulator quality problems; poor plasticization, low processing temperature, or excessive lubrication.

    Solution: Adjust the amount of foam regulator and foam agent, choose the foaming agent with higher melt strength and viscosity; appropriately reduce the amount of PE wax as an external lubricant, and appropriately increase the temperature of the screw barrel to make the plasticization better.


    Uneven thickness of PVC foam board surface

    Reason analysis: Uneven material discharge

    Solution: can adjust the opening degree of mold lip, if the flow rate is too big, can adjust the flow blocking bar, formula adjustment, generally, the inner lubrication is thicker in the middle, the outer lubrication is faster on both sides. Adjust the amount of internal and external lubricant according to the actual situation.

    KT Sheet VS PVC Foam Sheet - Which Is The Best For You?


    PVC foam sheet is more versatile and has better material properties. PVC foam sheet is harder and heavier than kt sheet. Due to the high density of PVC, the weight is 3-4 times heavier than the KT sheet.


    The differences

    1. PVC material is hard, suitable for machine engraving, KT board material is brittle can not afford machine engraving, but suitable for manual engraving.

    2. PVC is a plastic material, while KT board is a foam material.

    PVC board and KT board surface can be used to cover the picture, PVC board for outdoor, KT board for indoor, PVC board can be used for a long time, KT board is short-term use.

    4. PVC has strong scratch resistance, kt board is more fragile and easy to produce scratches.

    5. PVC board is hard and not easy to cut by hand, KT board is less hard and can be cut by hand.

    7. PVC is strong in durability and suitable for long-term use, KT board is weak in durability and suitable for short and medium-term use. (Within 1-2 years).

    8. PVC board is suitable for outdoor use, PVC board is suitable for indoor use.

    9. PVC price is 3-4 times the price of kt board (also weighs 3-4 times). Better PVC in 5-10 times more.

    10. KT board is not sun-proof, not waterproof, encountering sun and rain surface will blister, deformation, and thus affect the surface quality of the picture. PVC board is sun-proof, waterproof, encountering sun and rain will not be deformed.

    11. PVC also has the characteristics of fire and heat resistance, can replace wood, as a fireproof material.

    12. KT board is used for a variety of shaped labels, hand-raised signs, supermarket personalized inserts, mostly for short-term display.

    13. PVC is more used for laser engraved letters and various cultural walls, backdrop shapes, mostly for long-term use.

    14. PVC is heavy and needs to be reinforced and installed, KT is light and easy to install.


    Different application scope

    KT board is mainly used for indoor short-term advertising display board, or in the above stickers or say framed printed PP paper. KT board is mainly used in the indoor signage industry, DIY production (especially model production), and cosplay props.

    PVC is mainly used for outdoor advertising signs, construction site signage, etc. Indoor can also be used, such as the workshop plant and another harsh environment of the logo, placards.

    Other uses.

    PVC is more often used for laser engraved words and various cultural walls and backdrop shapes, mostly for long-term use.
