Data Source:Longzhong Information

Based on the East China region, the polypropylene yarn price closed at 7,069 yuan/ton today, up 13 yuan/ton from yesterday. The national average yarn price was 7,099 yuan/ton, up 3 yuan/ton from yesterday, in line with the morning expectations. 。

3 Price prediction

From the supply side, the high level of maintenance losses has to some extent offset the incremental pressure brought by the release of new capacity. However, the weak market demand situation has not fundamentally improved, and demand recovery still needs to be verified over time. The contradiction in the supply-demand fundamentals remains, and there is insufficient momentum for short-term polypropylene price increases. It is expected that tomorrow's price will be within 7020-7200 Yuan / Tons range oscillation.

PVC: Spot trading remains stagnant; PVC prices rise slightly during the session.

1. Today's Summary

2 Spot Market Overview

Based on the Changzhou market in East China, today's cash settlement price for calcium carbide produced by the electric furnace method in East China is 4,920 yuan/ton, an increase of 30 yuan/ton compared to the previous trading day. 。

The domestic PVC spot market prices remain firm, with intraday increases driven by sentiment in the ferrous sector. Spot trading activity is subdued, and there has been no short-term improvement in fundamentals. In East China, carbide-based PVC is quoted at RMB 4,880-5,000/ton (cash, ex-warehouse), while ethylene-based PVC is at RMB 4,850-5,150/ton.

3、Price forecast

The domestic PVC fundamentals have not improved recently, with few maintenance activities at upstream production enterprises and additional new supplies, resulting in a significant month-on-month increase in market supply. Meanwhile, domestic demand remains stable, and foreign trade exports are primarily focused on fulfilling orders. The supply-demand contradiction has intensified, leading to a substantial expected increase in industry inventories, putting pressure on the market. On the macroeconomic front, driven by intra-day movements in coke and other ferrous markets, market prices have slightly increased. However, there has been no impact on costs or other factors. In the short term, the market fundamentals are under pressure from supply and demand, spot prices are fluctuating weakly, and macroeconomic sentiment can easily disrupt market trends. It is expected that the cash on delivery price for acetylene-based PVC type 5 in the East China region will be 4800-4950 yuan/ton.

Some domestic products saw a decrease of 50 RMB/ton compared to yesterday. With increasing cost pressures, domestic PC manufacturers are maintaining stable pricing. In the spot market, some prices continue to decline slightly. Industry supply and demand pressures remain unchanged, and low prices fail to boost market sentiment. Holders maintain sales in line with the market, while downstream rigid demand lags behind, resulting in a sluggish trading atmosphere.

3 , Price Prediction

Recently, the main raw material bisphenol A has stopped rising and is stabilizing, with limited price increases that have not significantly transmitted to PC. Recently, most domestic PC plants have maintained stable operations, with industry capacity utilization remaining above 80% at a high level. However, downstream demand is affected by unfavorable factors such as the off-season for consumption, and short-term improvement is still difficult to expect. Driven by strong supply and demand pressure, the domestic PC market is expected to continue fluctuating and declining.

3. Price Prediction

The current market remains cost-driven, with supply and demand maintaining a stable state: the supply side continues to be stable, and the demand side, including downstream and traders, only replenishes based on low-price rigid demand. Today, driven by a rebound in raw materials, bottle chip prices have been adjusted upward accordingly. The price increase in the polyester bottle chip market is significant, and processing fees have slightly recovered from low levels. However, considering the relatively sufficient spot circulation, market enthusiasm for price chasing remains cautious. It is expected that tomorrow's polyester bottle chip water bottle material spot price in the East China market will be between 5,900-6,000 yuan/ton. Going forward, attention should be focused on changes in raw materials. (Unit: yuan/ton)

Table 1 Domestic PBT Price Summary (Unit: Yuan/Ton)

Based on the East China region, the mainstream price of low to medium viscosity PBT resin today is between 7,750 and 8,200 yuan per ton, remaining stable compared to the previous working day. Today, the PBT market is weak and wait-and-see, the PTA market has slightly rebounded, and the BDO market has seen a wide decline. With raw material prices continuing to weaken, most players in the PBT market are pessimistic about the future. The market is running weakly, with reports of low prices. According to Longzhong Information, the price of low to medium viscosity PBT pure resin in the East China market is 7,750-8,200 yuan per ton.

3 Price Prediction

The PBT market is expected to experience a weak and volatile trend. On the raw material side, PTA is in its traditional off-season with poor demand performance, and low processing fees have led some enterprises to reduce their load. Overall market sentiment is warming up, raw material supply is relatively tight, and cost support is re-emerging, so the short-term PTA spot market is likely to continue rebounding. The BDO market shows no positive signs in supply and demand, with major operators adopting a bearish sales attitude, and deal-making mostly involves concession negotiations, resulting in a weak and volatile market. With the downward trend of raw materials continuing, the PBT market is likely to follow suit with increased downward pressure, and operator sentiment remains bearish. Therefore, Longzhong expects that tomorrow the East China market price for medium and low viscosity PBT resin will be around 7,700-8,200 RMB/ton.

POM: Tight Spot Supply, Firm Market Trend
