pc plastics price trend in recent years

1. Recent price trend During the period from October 30 to November 7, 2025, the average price of PC in the national mainstream market fluctuated slightly in the range of 13000 yuan/ton. On November 7, it was reported to be 130552 yuan/ton, a single-day drop of 0.27%. As of November 11, the benchmark price of PC mixed for business clubs was approximately 140333 yuan/ton, a slight decrease of 0.94% from the beginning of the month, reflecting a mixed and volatile pattern in the market in early November.

2. As of August 1, 2026, there are significant differences in the domestic PC plastics market prices according to the classification of new materials and waste plastics; in July, the domestic PC market fell first and then rose, and the market is expected to continue to consolidate in August.

3. The operating rate of domestic PC aggregation enterprises has rebounded. The load of Pingmei Shenma has stabilized after the restart, Luxi Petrochemical has restarted a production line, and Zhangzhou Qimei is about to resume work. The overall load rate of the industry has reached about 80%, and the average weekly output has returned to around 50,000 tons; although short-term output supply has limited price support, it has improved the market's expectations for supply stability to a certain extent.

How can pc plastic parts crack

1. The root cause of cracking of PC plastic parts is usually directly related to stress, environment, external impact or material defects. Cracking caused by molding or assembly stress Improper injection molding process (such as too fast injection speed and too long holding time) will solidify internal stress, and this hidden stress will be suddenly released during use and cause cracks; forced assembly of interference fit will also cause plastic parts to withstand excessive extrusion, such as "barely stuck parts" that easily break at stress concentrations.

2. The main factor leading to cracking PC plastic itself has a certain internal stress, while silicone oil as an organic silicone fluid may cause swelling. When silicone oil molecules penetrate into the PC molecular chains, the intermolecular force will be reduced, causing internal stress to be released and causing cracking. Especially in high temperature and high humidity environments, or when plastic parts are squeezed by external force at the same time, the risk of cracking will increase significantly.

3. Stress cracking refers to a complex failure behavior in which plastic products crack and destroy in advance when exposed to chemical media and simultaneously under the action of stress.

4. During the processing process, if the pressure is too large, the speed is too fast, too much filling, and the injection and pressure holding time are too long, the internal stress will be too large, which will cause cracking. Therefore, it is necessary to reasonably adjust the mold opening speed and pressure to avoid rapid and strong drawing of the part leading to mold release cracking. Properly increasing the mold temperature can make the part easier to release, while appropriately reducing the material temperature can prevent decomposition. Weld lines and plastic degradation can reduce mechanical strength and lead to cracking.

5. In power equipment such as chargers, power adapters, and power strips, PC+ABS alloy has become the core material for plug pins, shell buckles and internal structural parts due to its excellent high temperature resistance, insulation and mechanical strength. It can be used as small as mobile phone charger pins to industrial power strip terminal fixing structures.

6. Ordinary lubricating greases contain mineral oil and corrosive additives, which will invade plastic molecules and cause stress cracking, whitening, swelling and softness; the grease is sticky and dusty, causing structural jams and poor positioning. It must be chemically inert, non-corrosive, non-bursting plastic special grease, low volatility, non-oil seepage, smooth damping, compatible with all modified plastics ABS, PC, PC+ABS.

What are the driving factors behind the rebound in polycarbonate pc prices in July 2026

The rebound in polycarbonate (PC) prices in July 026 was mainly driven by three types of factors: supply, raw material, and demand, which jointly drove global PCs on the supply side into a vacuum period for expansion.Has pc plastics ever fallen to the limit?There is basically no new production capacity in China, and the utilization rate of industrial production capacity has increased from about 85% in 2025 to more than 90%.
