Every Ton Directly Reduced By 500! Annual Consumption Exceeds 1000 Tons, This New Material Replacing 2426H Can Help You Earn Over 500,000!

In 2025, the domestic polyethylene market is deeply trapped in a supply-demand imbalance. LLDPE production capacity has increased from 10.01 million tons in 2020 to 16.84 million tons in 2025, a growth of over 68% in five years. Meanwhile, LDPE remains the product with the highest import dependency among the three major varieties, with an estimated import volume of about 2.4 million tons in 2025. At the same time, the market price for LDPE film resin continues to operate in the range of 8,800 to 9,600 yuan/ton, with the price difference from LLDPE consistently maintained at over 1,500 yuan/ton.

On one side are overcapacity and cutthroat price competition.LLDPE, on one hand, is import-dependent and subject to price fluctuations. LDPE - Behind the huge price gap lies a once-in-a-lifetime substitution opportunity.

When the patented technology of the Chinese Academy of Sciences meets a...The Era of “Cost Reduction”

In November 2024, a new LLDPE material named “2008” quietly emerged. It was developed using patented technology from the Chinese Academy of Sciences, adoptingLong-chain branched molecule design technologyIn the aggregation process, special additives were introduced, significantly enhancing the melt strength while maintaining the performance of the linear materials.Simply put, the molecular structure of LLDPE was modified to make it closer to that of LDPE.

The objective of this material is very clear:Replace the two most mainstream options in China.LDPE grades — 2426H and 2420H.

But the problem is: in the market,LLDPE is inherently cheaper than LDPE, so if you replace the more expensive LDPE with the cheaper LLDPE, the price should naturally be lower—this is the customer's first reaction.

But things weren’t that simple.

Why aLLDPE dares to benchmark against LDPE prices?

One of the most frequently asked questions by customers is:“This is LLDPE; why are you selling it at the LDPE price?”

The logic is as follows:Although 2008 is LLDPE, its molecular structure has undergone fundamental changes after being treated with the long-chain branching technology of the Chinese Academy of Sciences.Not there.It is not an ordinary grade casually produced by the LLDPE unit, but a special material based on an CAS patent and defined as an innovative product within the two major oil systems.It is precisely because it cannot be produced in high-pressure devices that this unique category has emerged.

With the backing of Sinopec and PetroChina, combined with patented technology from the Chinese Academy of Sciences, the resulting material performance matchesIf it’s so close to LDPE in density, what makes it so much cheaper than LDPE?

The answer is very realistic:Because the market does not recognize it.They don’t buy into “technology stories”; they only care about “price numbers.”

So, translate the above content into English and output only the translation result directly, without any explanation.The pricing strategy in 2008 was highly pragmatic—than what the customer is currently using2426H/2420H are at least RMB 500 cheaper per ton, with the difference reaching up to RMB 800–1,000.

One ton of rain.500. Using 1,000 tons a year means 500,000. Putting 500,000 into pure profit is not a small amount for any manufacturing enterprise.

“It works perfectly fine for me, so why should I switch?”

LDPE is not hard to buy; 2426H and 2420H are readily available. Customers are using them just fine, so why should they switch?

The answer to this question has two layers: Translate the above content into English and output only the translation result directly, without any explanation.

Layer one: Cost reduction is the hard truth. 

In present-day ChinaIn a market environment where “cost reduction and efficiency improvement” has become the main theme, anything that can...Help businesses save money.Any plan worth listening to.The performance of 2008 can reach 85–90 points compared with the customer’s existing material. Although there is still a slight gap, for the vast majority of applications, excess quality is itself a form of waste. If a 90-point material can meet the requirements, why pay a premium for a 95-point one?

Second layer: Not all scenarios require complete replacement. 

For products with less stringent requirements (such as protective films for building materials), this can be...100% replacementThe customer's original formula was 3 parts high-pressure material plus 1 part other material; now all 3 parts of the high-pressure material are directly replaced with 2008.For high-demand precision films (such as food packaging and electronic protective films), it is recommended to replace half.—for example, the original 3:1 formula would become 3:0.5:0.5, where 0.5 is the original 2426H and the other 0.5 is 2008.

What problem does “long-chain branching” actually solve?

The fundamental difference between LLDPE and LDPE lies in their molecular structures. LDPE has long-chain branching, giving it high melt strength and resulting in films with good stiffness and strong stability; LLDPE has a linear structure, so its melt strength is naturally lower.

The 2008 “long-chain branching technology” is equivalent to “building bridges” on the linear molecular chains of LLDPE, chemically connecting structures that originally could not be linked, so that the entire molecular chain exhibits structural characteristics close to those of LDPE in the reactor.This is what qualifies it to replaceThe root cause of LDPE.

This technology is easy to describe but difficult to implement. The catalyst formulation is like a thin layer of window paper.It feels uncomplicated once it's figured out, but for those who don't know, it may take a year or five years of research to make a breakthrough. The patent protection from the Chinese Academy of Sciences ensures that this material is... Exclusive ownership by only one company within 9 years (5+4-year agreement)。

Which customers are best suited to use it?2008？

Building materials protective filmFor applications with moderate requirements for thickness and stiffness, 2008’s advantage in melt strength is actually a plus. For three-layer co-extruded construction film, all three layers can be replaced without any problem.

Industrial packaging film— The requirements are relatively standard, with extremely high adaptability.

Small appliance protective filmFor products such as rice cookers, pressure cookers, heaters, garment steamers, and shavers, the surface protective film with a 2008 grade is fully sufficient in performance.

Is the 2426H expensive now? Not really—it has already dropped from its peak of over 12,000 yuan to around 9,000 yuan. But in an era where “cost reduction” has become the main theme, 500 is 500, saving 1000 is 1000.。

A product backed by patents from the Chinese Academy of Sciences, supported by Sinopec and PetroChina, with performance reachingLDPE with an MFI of 85–90, yet priced RMB 500–1,000 per ton cheaper—a material worth spending ten minutes to learn about for any manufacturing company pursuing profit.
