When Standard TPU Grades Fail in Film Extrusion Applications
Application Note When Standard TPU Grades Fail in Film Extrusion Applications TPU film extrusion projects often begin with standard grades that appear suitable during initial trials. In many cases, samples pass basic evaluation, only to encounter instability, surface inconsistency, or performance drift during continuous production. These failures are rarely random and usually indicate structural limitations of standard TPU grades. Application Context TPU films are widely used in bedding protection, medical covers, breathable laminations, and functional packaging. While standard TPU grades are often sufficient for short trial runs, film extrusion places unique demands on melt stability, surface uniformity, and long-term process consistency. Why Standard Grades Often Reach Their Lim... -
Extrusion Stability vs Initial Appearance in TPU & TPE Applications
Application Note Extrusion Stability vs Initial Appearance in TPU / TPE Applications In many TPU and TPE extrusion projects, material evaluation is heavily influenced by initial sample appearance. Smooth surface, good gloss, and clean profiles are often treated as indicators of material quality. However, materials that look better at the sample stage frequently perform worse in long-term, continuous production. Application Context Extrusion processes are widely used for wire and cable jackets, profiles, tubes, and flexible components. During early trials, evaluation often focuses on surface smoothness and visual consistency of short sample runs. These early impressions, while intuitive, do not reflect the conditions of continuous industrial production. The Hidden Trade-off In sof... -
Why “Correct Hardness” Still Fails in TPU / TPE Applications
Application Note Why “Correct Hardness” Still Fails in TPU / TPE Applications In many TPU and TPE projects, material selection often begins with a single number: hardness. While hardness is an important descriptor, it is frequently treated as a decision variable rather than a result. This oversimplification is one of the most common reasons why applications fail even when the “correct” hardness has been selected. Application Context Hardness-based selection is common across extrusion, injection molding, overmolding, and soft-touch applications. In early project stages, materials with similar Shore hardness values are often considered interchangeable. However, field performance frequently diverges despite identical nominal hardness. Key Constraints That Ha... -
Europe’s Chemicals Sector: Potential Shift from Net Exporter to Net Importer
Market insiders note that as Europe’s market influence weakens, global chemical trade flows are tilting toward emerging Asian markets, with Asia (especially the Middle East) solidifying its status as a top chemical export hub. This trend could drive Europe to switch from a net exporter to a net importer of chemicals in the long run. Europe’s chemical market is in a sustained downturn. Stefan Schnabel of Germany’s Helm AG points out that Europe’s shrinking income-generating workforce and outflow of consumer spending have weakened local demand, benefiting surplus-producing regions like the Middle East and East Asia. Udo Lange of Denmark’s Stolt-Nielsen adds that Europe’s chemical industry is seeing capital outflow, domestic plant closures, and minimal new local investments—with short-term... -

Focus on Hainan’s Island-wide Independent Customs Operation! Zero Tariffs on 6,600 Tariff Lines and 15% Income Tax Preference: How Can Plastics and Chemical Enterprises Seize Policy Dividends?
On December 18, 2025, Hainan officially implemented its customs closure, with a series of supporting documents, including the “Notice on Taxation Policies for Goods Entering and Exiting the ‘First Line’ and ‘Second Line’ in the Hainan Free Trade Port and Their Circulation Within the Island,” simultaneously taking effect. These documents clarified core rules such as the prohibited and restricted import/export lists and the catalog of taxed imported goods. This significant measure has drawn widespread attention, with the distinction between the concepts of “border closure” and “island sealing” becoming the focal point for the public. Clarifying the differences between the two is key to understanding the essence of the policy. The... -
Profits From Oil-Based Polyethylene Are Expected To Grow In 2025, Boosting Production Enthusiasm.
In 2025, due to the continuous decline in international oil prices, the competitive landscape of the polyethylene market has undergone a fundamental transformation. Shift in Competitive Focus: Industry competition has shifted from a simple game of demand to a “battle of production technology routes” driven by costs. Rise of the Oil-Based Route: Leveraging their sharply increased cost advantage, oil-based polyethylene enterprises have seen significant profit growth (theoretical profit reached 422 RMB/ton from January to November 2025, a year-on-year increase of over 300%) and reclaimed dominant market pricing power from coal chemical and light hydrocarbon cracking routes. Pressure on Other Routes:Coal-Based Polyethylene: Due to its cost dependence on relatively stabl... -
Plastic Products Exports Decline Polyolefins Remain Weak
In October 2025, China’s foreign trade import and export growth slowed significantly. Affected by multiple factors including falling international oil prices and U.S. tariff policies, the export growth of plastic products remained sluggish, while the polyolefin market continued to face an oversupply situation with prices lingering in a low-range fluctuation. Customs data shows that China’s total import and export value in October 2025 reached 520.63 billion US dollars, a month-on-month decrease of 8.1% and a slight year-on-year drop of 0.3%. Among this, exports stood at 305.35 billion US dollars, down 1.1% year-on-year. For specific products, the export value of plastic products in October was 55.04 billion yuan, a sharp year-on-year decline of 9.5%. From January to ... -
Supply-Demand Imbalance Coupled With The Off-Season Effect, The PVC Market Is In Weak Oscillation And Grinding At The Bottom.
Currently, the PVC market is in a weak oscillating pattern, primarily due to the unresolved supply-demand imbalance. Core Supply and Inventory Situation The momentum of industrial production resumption has exceeded the impact of maintenance, with the operating rate of PVC powder rising to 80.55%. New production capacity in 2025 is being released concentratedly, with 2.2 million tons already put into production and 500,000 tons remaining to be released subsequently, resulting in loose supply. Social inventory in East and South China has increased to 544,100 tons, with slow inventory digestion. High inventory levels will persist throughout the fourth quarter. Price and Cost Performance Both futures and spot markets have weakened simultaneously. The closing price of the main PVC futures... -
