Polyethylene glycol ester or polyglycolic acid (PGA) is a biodegradable, thermoplastic polymer and the simplest linear aliphatic polyester.

PEEK is a special engineering plastic with excellent performance, which can be used for a long time at 250 ℃. It can maintain high bending strength and compression strength at high temperatures, has high rigidity, good dimensional stability, and a small coefficient of linear expansion.
Can withstand almost any chemical except concentrated sulfuric acid; And it can maintain good chemical stability even at higher temperatures, while also possessing flame retardancy.

The 5G era has arrived, and due to its high-frequency and high-speed characteristics, there will be significant changes in the material end. LCP has encountered such a 0 → 1 development opportunity, and with its low impedance and high resistance, it is expected to become the most suitable material. With the increase of 5G frequency, the penetration rate of LCP materials and their products will gradually increase, which is expected to rapidly increase the entire LCP market to over 10 billion yuan.

Polyimide (PI) refers to a high molecular weight polymer with an imide structure in its main chain. Polyimide is a very large family, and the main chain of high-performance PI is mostly composed of aromatic and heterocyclic rings as the main structural units

The composition of ETFE membrane material is ethylene tetrafluoroethylene copolymer, which is a transparent membrane material without fabric substrate, and its elongation can reach 420% to 440%. The transmittance spectrum of ETFE film material is similar to that of glass (commonly known as soft glass).
