Photoresist plays a crucial role in semiconductor manufacturing and is one of the core materials in chip manufacturing. Photoresist plays a crucial role in the photolithography process, as it is the key medium for transferring designed circuit patterns onto silicon wafers. The quality of photoresist directly affects the performance and yield of chips, so its technical threshold is very high!

PET： Polyethylene terephthalate is a dynamic process in which different industries or different industries within the same industry infiltrate and intersect with each other, ultimately merging into one entity.

PETG： Cyclohexanediol (copolyester) English: Poly (ethyleneterephthalateco-1,4-cylclohexylenedimethylene terephthalate)

The biggest feature of PETG compared to PET is that PETG conforms to the concepts of environmental protection and food FDA certification. PETG is currently receiving increasing attention from related products at home and abroad

Quinoline compounds can be used to produce pharmaceuticals, dyes, photosensitive materials, rubber, solvents, and chemical reagents. Quinoline is mainly used in medicine to manufacture three major categories of drugs: nicotinic acid, 8-hydroxyquinoline, and quinine. Niacin based drugs include nicotinamide, cardiac stimulants, stimulants, and drugs for treating tapeworm diseases; 8-hydroxyquinoline series can be used to manufacture drugs for treating amoebiasis and wound disinfectants, as well as antifungal agents and textile auxiliaries; Boramequinine, chloroquinine, and hydroxyquinine are synthetic drugs with specific efficacy in treating malaria. Isoquinoline can be used to manufacture insecticides, antimalarials, rubber vulcanization accelerators, and chemical reagents for the determination of rare metals. Methyl quinoline can be used to manufacture color film sensitizers and dyes, as well as solvents, impregnating agents, corrosion inhibitors, quinine based drugs, and insecticides. The extraction process of quinoline compounds can be found in heavy pyridine refining.
