1 Material overview and characteristics PPA, full name polyphthalamide, is a semi-aromatic polyamide with no less than 55% terephthalic acid or phthalic acid as raw material, commonly known as aromatic high temperature nylon. Long-term operating temperature up to 180℃, short-term temperature resistance up to 290℃, with high modulus, high hardness, high cost performance, low water absorption, dimen...

From May 5 to 11, the 2025 Keqiao Fashion Week (Spring) was held at the Oriental Milan International Fashion Release Center in Keqiao District, Shaoxing City, Zhejiang Province. For the first time, humanoid robots made a live appearance on the runway during the opening show, blending technology with fashion and showcasing a new kind of catwalk style. The element of technology was not limited to th...

PEEK (Polyether Ether Ketone) Material Overview Introduction PEEK (Polyether Ether Ketone) is a linear aromatic high-performance polymer with repeating units of –O–Ph–O–C(=O)–Ph– in its molecular backbone. It is a semi-crystalline thermoplastic and a high-performance specialty engineering plastic with numerous advantages over other specialty plastics. PEEK has a melting point of 334 °C, a softenin...

A humanoid robot can contain hundreds of structural and transmission components. Across the industry, two material-selection mistakes keep appearing—and both can be costly: Mistake 01 Saving on specialty materials when they are actually needed —For example, using PA66-GF30 for a bracket near a motor can lead to creep deformation, dimensional changes, and position drift under prolonged high-tempera...

PEEK for Robotic Joints: Where It Fits, Where Its Limits Are, and What Is Holding It Back With a density of approximately one-sixth that of steel, along with self-lubricating properties and the potential to reduce noise, PEEK offers a compelling combination of properties for certain robotic joint applications. However, major load-bearing joints in the lower limbs are not necessarily where PEEK per...
