How Polyphthalamide PPA Resin is Different from Other Similar Materials
Polyphthalamide (PPA) resin is a high-performance engineering plastic. Compared with other similar materials, it has many unique features.
In terms of heat resistance, PPA resin is outstanding. If the ancient good materials need to be tested by fire and not destroyed, PPA resin can withstand high temperature. In many high temperature environments, it can still maintain the stability of its physical properties without softening and deformation, which is difficult for many ordinary plastics to achieve. For example, polyamide (PA) series plastics, although they also have certain heat resistance, have slightly less dimensional stability at high temperatures than PPA.
In terms of mechanical properties, PPA resin is rigid and powerful. Like a tough weapon in ancient times, it has high strength and high modulus, considerable tensile strength and flexural modulus, and can withstand large external forces without breaking or deformation. It can be widely used in fields that require strict mechanical properties. Compared with materials such as polypropylene (PP), PPA has significant advantages in strength. Although PP is light, its strength is far inferior to that of PPA.
Chemical stability is also a major highlight of PPA resins. Just like a strong fortress in ancient times that can resist foreign invasion, PPA resins have good resistance to many chemicals. Whether it is an organic solvent or a corrosive chemical reagent, PPA resins can withstand erosion to a certain extent. Materials such as polystyrene (PS) are prone to swelling and cracking under the action of certain chemicals.
In addition, the processing properties of PPA resin are also relatively unique. It can be processed by injection molding, extrusion and other methods to meet the manufacturing needs of different products, and in the processing process, the molding cycle is short and the production efficiency is high, just like the skilled craftsmen in ancient times who quickly created exquisite utensils with exquisite skills. Compared with some materials with complex processing techniques and difficult molding, this point has obvious advantages.

What are the main points of the processing technology of Polyphthalamide PPA Resin
Polyphthalamide is polyphthalamide, often abbreviated as PPA. The main points of the processing process of PPA resin are as follows:
First, pre-drying. PPA has strong moisture absorption and needs to be fully dried before processing. If baked at 120 ° C for 4 to 6 hours, reduce the moisture content to less than 0.05%, otherwise the moisture will cause resin hydrolysis at high processing temperature, deterioration performance, and the product will have defects such as bubbles and silver wires.
Second, processing temperature. PPA has a high melting point, and the processing temperature is usually 300 to 350 ° C, which is adjusted according to the brand and equipment. Low temperature, high viscosity of the resin melt, difficult to fill the mold, causing the product to be short of material and the surface is not bright; high temperature, the resin is easy to decompose, the performance is reduced, and the color becomes darker.
Third, injection pressure and speed. Due to the high viscosity of PPA melt, it is necessary to appropriately high pressure and speed during injection molding to ensure that the melt quickly fills the mold cavity. However, if the pressure and speed are too high, it is easy to produce flash, trapped gas and other problems. It needs to be optimized according to the product structure and mold design.
Fourth, mold design. The mold needs a good exhaust system to discharge the gas in the melt to avoid trapped gas burning. The gate size and form are reasonably designed to ensure uniform filling of the melt and avoid defects such as weld marks. Mold surface treatment to improve the surface quality of the product.
Fifth, cooling. The crystallization rate of PPA is fast, and the cooling process has a great impact on the performance and dimensional accuracy of the product. Reasonably design the cooling water circuit to ensure uniform cooling of the mold, control cooling down, and avoid deformation and shrinkage of the product.
Sixth, post-treatment. After the product is formed, post-treatment is often required, such as 150 to 200 ° C hot air aging for several hours, eliminating internal stress, stabilizing size, and improving crystallinity and mechanical properties.

What is the Market Price Range for Polyphthalamide PPA Resin?
Polyphthalamide is polyphthalamide, often abbreviated as PPA. As a high-performance engineering plastic, the market price range of PPA resin fluctuates greatly and is deeply influenced by many factors.
From the perspective of raw materials, the prices of various monomers that PPA resin synthesis relies on, such as dibasic acids and dibasic amines, will change due to fluctuations in the prices of basic raw materials such as oil and natural gas. If the price of oil rises sharply, the price of the monomer as the source will also rise, which will in turn drive the price of PPA resin. For example, during the oil crisis, the prices of many chemical products that use petroleum derivatives as raw materials rose sharply.
The production process is also a key factor. Advanced and mature production processes can effectively reduce production costs. If an enterprise develops a new and efficient production technology that can improve output efficiency and reduce energy consumption, the price of the enterprise's products may be more competitive. The old production process may lead to high waste rate and energy consumption, which will increase costs and lead to high prices.
The following pairs of market supply and demand have a significant impact on prices. In the stage of rapid development of electronics, automotive and other industries, the demand for PPA resins is strong. If the supply cannot keep up in time, the price will rise. On the contrary, when the market demand is weak, but the company's production capacity remains high, and the supply exceeds the demand, there will be downward pressure on prices. Taking the automotive industry as an example, if automobile production declines sharply due to a sluggish market, the demand for PPA resins in automotive parts applications will also drop sharply, affecting prices.
Quality differences also affect prices. High-quality PPA resins perform well in terms of mechanical properties, heat resistance, chemical resistance, etc., and can meet the needs of high-end fields, so the price is naturally higher. Like PPA resins required in the aerospace field, the quality requirements are extremely strict, and their price is much higher than that of ordinary industrial products.
In the current market, the price of ordinary grade PPA resins is roughly in the range of 30-80 yuan per kilogram. And high-performance, high-purity PPA resins used in high-end electronics, aerospace and other fields can cost up to 150-500 yuan per kilogram, or even higher. This price range is not static, but will constantly fluctuate with the dynamic changes of the above factors.
From the perspective of raw materials, the prices of various monomers that PPA resin synthesis relies on, such as dibasic acids and dibasic amines, will change due to fluctuations in the prices of basic raw materials such as oil and natural gas. If the price of oil rises sharply, the price of the monomer as the source will also rise, which will in turn drive the price of PPA resin. For example, during the oil crisis, the prices of many chemical products that use petroleum derivatives as raw materials rose sharply.
The production process is also a key factor. Advanced and mature production processes can effectively reduce production costs. If an enterprise develops a new and efficient production technology that can improve output efficiency and reduce energy consumption, the price of the enterprise's products may be more competitive. The old production process may lead to high waste rate and energy consumption, which will increase costs and lead to high prices.
