Why is peek plastic price so expensive?

In the plastics industry, there is a plastic material “PEEK” known as “gold” . The price can easily reach thousands of yuan per kilogram, and demand exceeds supply.

Google AI answer:

PEEK plastic, also known as polyetheretherketone, is known for its excellent performance but also tends to be on the pricier side.expand_more Here’s a quick rundown on its pricing:

• Generally more expensive than other engineering plastics: PEEK offers superior strength, stiffness, chemical resistance, and thermal stability compared to common options like nylon or polycarbonate.expand_more This performance comes at a cost, though.expand_more
• Price range: Typical prices can range from US$70 to US$110 per kilogram (kg) [Alibaba, Made-in-China.com]. It can also be sold by the pound, and the conversion rate needs to be considered.
• Factors affecting price: Several factors can influence the price, including the specific form (granules, rods, films), quantity purchased, and even the manufacturer.

So what is PEEK? Shuo Creative Materials will give you the answer:

Polyetheretherketone resin (polyetheretherketone, PEEK resin for short) is a semi-crystalline, high-performance thermoplastic engineering plastic. It is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. It can be manufactured and processed into various mechanical parts, such as automobile gears, oil screens, shift starters; aircraft engine parts Components, automatic washing machine wheels, medical device parts, etc.

When it comes to polyetheretherketone, it is well known that if plastic materials were compared to a pyramid, PEEK would be at the top. So why is the price so high? This is inseparable from its excellent performance.

PEEK performance

First of all, PEEK plastic has strong heat resistance. The high temperature resistance of PEEK plastic can reach 260 degrees, and the heat deformation temperature can reach 160 degrees. If modified with 30% glass fiber, its heat deformation temperature can reach 316 degrees Celsius. PEEK resin can still maintain high strength at high temperatures, with a flexural strength of up to 24MPa at 200°C, and a flexural and flexural strength of 12~13mp at 250°C.

Secondly, PEEK has excellent chemical stability and is resistant to almost all chemical reagents except concentrated sulfuric acid; its corrosion resistance is close to that of nickel steel, and it has its own flame retardancy. Peek’s V0 flame retardant level is as low as 1.45mm, and its LOI is 35%, its smoke and poisonous gas emissions are extremely low. It has excellent hydrolysis resistance and is insoluble in all common solvents. Even in a steam environment of 200-250°C or high-pressure water, it can be used for a long time without significant reduction in performance.

Thirdly, PEEK resin has significant tribological characteristics, excellent sliding wear resistance and fretting wear performance, especially it can maintain high wear resistance and low friction coefficient at 250°C;

In addition, PEEK plastic resin also has greater rigidity, good dimensional invariance, and a small linear expansion coefficient, which is very close to metallic aluminum materials. Easy to injection molding and extrusion molding, with good processing performance and high molding efficiency.
