Styrene downstream consumption analysis of PS Diffusion sheet
Before understanding the end consumption of the PS Diffusion sheet, there is a topic that cannot be avoided: the substitution relationship between the PS Diffusion sheet and the ABS sheet. Not only do they both use styrene as the main raw material, but if you have paid attention to the respective downstream consumption areas of PS and ABS sheets, you will find a high degree of overlap between the two, with basically half of them being used in the home appliance/electronics sector. For this part of the field, factories usually compare the economics of the two. When the price difference between the two is greater than $300, the substitutability of HIPS for ABS begins to emerge. Therefore, unlike ABS sheets and PS Diffusion sheets, which have a relatively balanced ratio in using their own raw materials, the end products vary greatly in the choice of ABS sheet and PS Diffusion sheet.
However, the choice between ABS and HIPS is not entirely based on economics. HIPS and ABS, in addition to the bending modulus, are close. Other aspects of the test HIPS performance are much lower than ABS, especially the impact strength. HIPS is more prone to aging. At the beginning of use, HIP can achieve the same effect as ABS, but with extended time and repeated high and low temperatures, the HIPS aging rate is much faster than ABS, resulting in a decline in service life. Therefore, HIPS is usually not suitable for application in everyday household appliances that are subjected to high temperatures.
The most typical application of PS Diffusion sheet in white goods is in the refrigerator. The material requirements for refrigerators include adequate mechanical strength, rigidity, dimensional stability, and creep resistance. In addition to the above mechanical properties, refrigerator-freezers also require non-toxic, odorless, low-temperature resistant, crack-resistant, and resistant to cooking oil. In the refrigerator in, the most common several materials, including HIPS, GPPS, PP, ABS, PVC, etc., in these materials is the most applied PS Diffusion sheet and ABS sheet. Of course, the use of PS is not static due to the ABS, as mentioned above, the sheet and PS Diffusion sheet alternative relationship, and some refrigerator manufacturers mainly use ABS sheet.
Air conditioners are also the most common consumer area for PS Diffusion sheets for home appliances. HIPS is most commonly used for air intake windows and front control panels in air conditioners. However, unlike refrigerators, HIPS can be replaced in large quantities by ABS sheets in air conditioners.
In addition to refrigerators and air conditioners, the PS Diffusion sheet in the display has some applications. However, the display in the material is still mainly ABS, PC, and PC / ABS. PS Diffusion sheet, both in the application ratio and unit usage, are not obvious. For other important white goods, washing machines, juicers, vacuum cleaners, water dispensers, rice cookers, microwave ovens, and other common small appliances, using PP and ABS-based, rarely use PS Diffusion sheets.
But in addition to home appliances, PS Diffusion sheets in daily necessities, packaging containers, and other aspects of the use of the proportion can not be ignored. Electronic appliances, packaging, and daily necessities accounted for 48%, 26%, and 26% of the total consumption of PS, respectively. And in the electronics industry, in addition to HIPS for home appliance production, GPPS ordinary material production of the organic board can also be used for injection molding parts, advertising floors, light boxes, etc., with GPPS special material can be used to manufacture LED light guide, diffusion board and transparent inner parts of electrical appliances and other products. Appliances accounted for PS consumption ratio is not as high as about half. At the same time, in the use of daily necessities, electronic products, packaging containers, etc., seasonality is relatively insignificant, flattening the seasonality of fluctuations in the production of home appliances.
In addition, extruded plastic panels are also a noteworthy area of consumption of PS Diffusion sheets. In the existing buildings, the vast majority of buildings for high energy-consuming buildings, and more than 80% of new buildings still belong to high energy-consuming buildings. According to relevant statistics, the energy consumption of the envelope structure accounts for 77% of the building's energy consumption, so exterior wall insulation is an important part of the building's energy saving. PS Diffusion sheet is an important material for exterior wall insulation.
