Why is PC gradually replaced by PP in the furniture industry?

First, let us get to know these two materials:

What is PC material?

In the industry, polycarbonate (Polycarbonate) is called PC. In fact, PC material is one of our industrialized plastics. The reason why it is widely used in production is entirely determined by its characteristics. PC has the unique advantages of fireproof, non-toxic and colorable. The key is that it has great expansion power, high temperature and low-temperature resistance, and good extensibility. The key is that the quality of the finished product is good. These have become the choice for many furniture to choose PC as the raw material. An important reason.

What is PP material?

PP is the abbreviation of polypropylene (Polypropylene), and it is also what we commonly call Fold-fold plastic, which is also a kind of industrial production plastic. PP is a synthetic plastic product, but it also has its own advantages and disadvantages. Many baby bottles will be made of PP material because it is resistant to high temperatures and is completely OK above 100 degrees Celsius, so it is suitable for the needs of frequent boiling water disinfection of baby bottles. The stability of PP is relatively good.

So why in the furniture industry, the PC materials are gradually replaced by PP materials? The reasons are as follows:

Cost factor

The raw material procurement cost of PC resin is much higher than that of PP. The worst raw material of PC is more than 20,000 a ton, and the raw material cost of PP is 10,000. PP is also one of the most widely used projects.

Fashion sense

In terms of the light transmittance of plastics, PC resin wins. PC is one of the three transparent plastics with excellent light transmittance. The finished furniture is transparent and colorless. The permeability of pp is very poor, and the usual PP has a hazy feeling of fog, which enriches the texture of the material and makes the color more matte, which makes it more advanced. The choice of multiple colors has also become a favorite for it. Reasons for welcome. Rich choices, not as single as PC material.

Material characteristics

The hardness and toughness of these two plastics are different. PC has excellent hardness, PP has very low hardness at room temperature, and it can be easily deformed and bent by external force. However, PP has very good toughness, commonly known as Baizhe glue, and is widely used in furniture. Its toughness makes it more strong and has better load-bearing capacity.

Manufacturability

The fluidity of PP injection is very good and it is easy to form, while the fluidity of PC is very poor and it is difficult to move the glue. In addition, PC is easy to decompose and change color at high temperature in injection molding, and injection molding requires a customized PC screw. So in fact, the processing cost of PC products is higher. At the same time, when PC injection products are made, due to their transparent characteristics and easy to see the bubbles and impurities inside, the yield is extremely low. If it is a high-end market, it is very difficult to control the quality of PC products, which also greatly increases production costs.

Safety factor

PC products may decompose bisphenol A, which is harmful to human health. PC high temperature does not produce bisphenol A, but bisphenol A is the raw material for the production of PC plastics. After the synthesis of bisphenol A, PC is produced. After chemical synthesis, the original bisphenol A is no longer there. It’s just that this synthesis process is a process, and there are deviations in the process, it is difficult to 100% complete reaction, and there may be residual bisphenol A (possibly). When PC encounters high temperature, it will cause bisphenol A to precipitate out of the plastic. Therefore, if there is residual bisphenol A in the material, both hot precipitation and cold precipitation will exist, and the cold precipitation is very slow.

All in all, the performance of PC and PP are different, and it is not possible to simply determine who is good and who is bad. It is still necessary to choose the best product for the scope of use. And PP is more widely used in the furniture field, which is why PP furniture is gradually replacing PC furniture.
