Raw material styrene rebounded slightly after stopping its decline, and the cost negative factors have eased somewhat. However, considering the high supply and shipping pressure, demand is below expectations, and in the short term, the PS market may see low-price sales with limited price fluctuations. It is expected that the transparent modified benzene in the East China market will be 8500-10300 yuan/ton.

general material
PE:Supply and demand improvement is limited, polyethylene prices fall
3, price prediction
In the short term, in terms of cost, the relatively firm crude oil prices provide some support to PE costs; in terms of supply, some enterprises are undergoing maintenance in the short term, which has somewhat alleviated market supply pressure; in terms of demand, although the overall downstream operation of PE has improved, the follow-up in demand is limited, mainly focusing on replenishing inventory based on rigid demand. Overall, the improvement in supply and demand is not significant, and it is expected that polyethylene prices will mainly fluctuate within a narrow range tomorrow.
PP:Cost-end benefits support boosting the polypropylene market center to shift upwards
3, price prediction
Demand-side weakness continues, with additional overseas tariffs leading to a reduction in export orders for manufactured goods. Supply-side expectations for recent increases remain unchanged, and future market valuation expectations are weak. Frequent short-term maintenance and rising costs at the cost end are beneficial to market sentiment, as merchants who have been building a bottom at low prices for a long time are testing higher offers to verify transactions. Recently, the market has been vying for territory between supply and demand and costs, and it is expected that the short-term polypropylene market will revolve around 7300-7430 yuan/ton to verify transactions. Special attention should be paid to the impact of tariff adjustments on downstream product exports, as well as the status of inventory along the industrial chain and demand-side variables.
PVC:PVC price increases slowly, trading atmosphere turns weak
3.price forecasttest
Recent macro policy expectations have boosted and upstream black sector benefits have pushed up PVC intraday prices; the basic supply and demand situation remains at an impasse, with concentrated maintenance seasons in the future, supply is expected to slow down, terminal demand mainly remains stable, spot prices follow the market trend and rise; costs are mainly stable in the short term, market expectations are still mainly affected by market fluctuations, there is insufficient support for continuous price increases in the spot market, and the cash price of the five-type calcium carbide method in the East China PVC market is seen in the range of 4900-5050 yuan/ton.

1、spot overview
Table 1 Domestic EVA Price Summary (Unit: Yuan/Ton)

Today's EVA market price fluctuates narrowly, with a weak trading atmosphere. Traders have low spot inventory, but under the backdrop of differing views on future prospects, some merchants are pre-selling futures, which constrains spot prices. Meanwhile, end-user enterprises' intention to stock up has decreased, mostly sticking to replenishing based on rigid demand, with actual transaction prices focusing on negotiation.
3.price prediction
Combining the analysis of driving factors, it is expected that the EVA price may undergo a high-level consolidation in the near future. The specific reasons are as follows:
supplyThe tight market supply situation has slightly eased, with some merchants pre-selling futures, which constrains the spot price.
requirements: input format:Downstream enterprises have a rigid demand for restocking, but the intention to stockpile is not high, showing some resistance to high-priced sources.

At the beginning of the week, the latest ex-factory prices from some domestic PC manufacturers remained stable, with a few adjusting downward by 150 yuan/ton; looking at the spot market, both East China and South China continue to show a weak consolidation pattern, with no significant improvement in fundamentals, slow spot trading, cautious and hard-to-lift market sentiment, some selling focuses continue to shift downward, poor new orders from downstream, very few inquiries and purchases in the market, and difficulty in increasing trading volume.
3. price prediction
Currently, the overall performance of the domestic PC market remains weak, with an unusually long decline in market conditions, significantly impacting market sentiment. Despite some PC facilities planning to reduce production or undergo maintenance in April, there has been no boost to the market as of yet.

Cargo holders mainly sold, downstream buyers replenished stocks as needed, transactions were sporadic.
3、price prediction
As the end of the month approaches, some inventory holders face pressure to sell. With expectations of increased supply, the polyester chip market is under growing pressure. Traders and end-users are not keen on stockpiling, and downstream buyers are only replenishing as needed, leading to a continuously weak trading atmosphere. Additionally, with the raw materials performing mediocrely, the polyester chip market may lack upward momentum. It is expected that the spot price for water bottle-grade polyester chips will move within the range of 6050-6130 tomorrow.
POM:Insufficient demand follow-up, POM market weak and steady with a wait-and-see attitude
3、price prediction
At the beginning of the week, the shipment situation in various regions did not improve, and the inventory pressure on petrochemical plants continued to increase. The short-term POM fundamentals lack support, and the market's pessimistic sentiment has intensified. Traders' operating mentality is poor, and there is still room for negotiation in the main quotations. Terminal orders are weak, and the buying and selling atmosphere will be difficult to be optimistic. It is expected that the short-term domestic POM market will fluctuate weakly.

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

in order toEast China region as the benchmark, today's mainstream price for medium to low viscosity PBT resin is 7900-8200 yuan/ton,unchanged from yesterday。Today, the PBT market is in a wait-and-see mode, the PTA market is operating weakly, and the BDO market is in a weak stalemate. The cost support is relatively weak, and the PBT market sentiment is bearish. There is a psychological game between supply and demand sides within the market, leading to a wait-and-see attitude. According to statistics, in the East China market, the price of low to medium viscosity PBT pure resin is 7900-8200 yuan/ton.
3, price prediction
It is expected that the PBT market will fluctuate within a range. In terms of cost, the PTA balance sheet maintains an expectation of inventory reduction, with no significant supply and demand contradictions, and the overall valuation is relatively low. However, there are many unstable external factors, commodities lack sustained driving force, and downstream operations are cautious, leading to a continued volatile pattern in the short-term domestic PTA spot market; at the beginning of the new BDO trading cycle, the market continues to adopt a wait-and-see attitude, with actual terminal demand remaining weak and price negotiations upon entry, and holding manufacturers having moderate confidence in the future market, with mainstream offers stable, and real transactions negotiated according to the market, with the market center showing a weak fluctuation. The cost support is average, and the PBT market mostly adopts a wait-and-see attitude, lacking clear bullish or bearish drivers, with the market center fluctuating within a range, thus it is expected that tomorrow's East China market for medium and low viscosity PBT resin will be in the range of 7900-8200 yuan/ton.

Table 1 Domestic Polyamide 6 Price Summary (Unit: Yuan/Ton)

Today, the polyamide 6 chip market has stopped falling. The price of caprolactam, the raw material, continues to decline. However, as chips are currently being sold at a loss, polymer companies are not keen on lowering prices further. Some chip prices have risen slightly, but overall downstream demand is limited, with purchases made selectively based on need and at lower prices. Transactions for some lower-priced chips have improved. In East China, the cash price for conventional spinning regular PA6 chips is 10,300-10,600 yuan/ton (short delivery), while the spot price for high-speed spinning is 11,300-11,800 yuan/ton (delivery against acceptance). In Chaohu, the self-pickup cash price is 9,600-9,700 yuan/ton.
3、price prediction
From the cost perspective, the caprolactam market is low or may continue to be in a low consolidation, with attention to the maintenance and load reduction of subsequent raw material enterprises; from the supply and demand perspective, polymer enterprises maintain high operating rates, some enterprises undergo maintenance and load reduction to alleviate inventory pressure, but downstream buyers are cautious in choosing to replenish stocks at lower prices. It is expected that the recent nylon 6 market will consolidate, and close attention should be paid to downstream demand and manufacturer price adjustment dynamics.
PMMA:inquiry limited light operation
Today's summary
Today's factory quotes are stable.
②、Today, the domestic PMMA particle utilization rate is 64%.
2spot overview
Table 1 Summary of Domestic PMMA Particle Prices (Unit: Yuan/Ton)

Taking East China as the benchmark, PMMA particles closed at 17,000 yuan/ton today, unchanged from yesterday, in line with early expectations.Today, the PMMA particle market maintains a stable transition trend, with no significant news. At the beginning of the week, the market is in a wait-and-see mode, with insufficient inquiries heard. There is only a small amount of downstream rigid demand buying, and the overall atmosphere is light. In the short term, the market situation will remain as it is.
3, price prediction
The short-term PMMA particle market is operating in a lukewarm manner, with the fundamentals remaining stable. The buying atmosphere within the market is somewhat stagnant, and downstream purchasing enthusiasm is insufficient, with most purchases being made on a need basis, making it difficult for negotiations to increase in volume. In summary, under the continuous game between upstream and downstream, it is expected that the short-term PMMA particle market price will have a higher probability of remaining stable. Actual transaction volumes need to be followed up, and continued attention should be paid to the dynamics of offers and bids.
PA66downstream cautious about high-price procurement market weak consolidation
3, price prediction
Demand side has not shown a significant recovery, and the high prices of aggregated companies' products are not selling well, leading to a gradual accumulation of inventory in the industry. Meanwhile, aggregated companies still face cost pressures. It is expected that the domestic PA66 will remain weak in the short term. Specifically, attention should be paid to the price guidance for Invista's hexamethylenediamine.
