THF is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, tape and film coatings, and used in combination. As a reaction solvent, the thickness and brightness of the aluminum layer can be arbitrarily controlled when used in the aluminum electroplating solution. THF itself can be polycondensed (ring-opening and repolymerization initiated by cations) into polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubbers with abrasion resistance, oil resistance, good low temperature performance and high strength; with dimethyl terephthalate and 1,4-butanediol to make block polyether polyester elastic Material.
Monoethylene glycol (MEG) is a colorless, odorless, and slightly viscous organic compound widely used in various industries. Primarily known for its role as an essential component in the production of polyester fibers, resins, and polyethylene terephthalate (PET) plastics, MEG serves as a crucial raw material in the manufacture of textiles, packaging materials, and plastic bottles. Additionally, its properties as a coolant and antifreeze make it a common ingredient in automotive and industrial applications, preventing freezing and overheating in engines and mechanical systems. MEG's versatility, solubility, and ability to lower the freezing point of water have established it as a vital compound in diverse sectors, from manufacturing to engineering.
It is used widely as an industrial intermediate to manufacture polyethylene terephthalate (PET) and dioctyl terephthalate (OECD, 2001). It is used in the Polyester Film (Audio/Video Tape, X-ray Film, Photo Film), Polyester Fiber, Pet Bottle, Polyester Adhesive, Engineering Plastics. DMT is volatile, it is an intermediate in some schemes for the recycling of PET.

BD is widely used. In the United States and Western Europe, more than half is used for the production of tetrahIdrofuran, followed by the production of �³-butIrolactone and polybutylene terephthalate, which are rapidly developing engineering plastics; BD is used as an additive Chain agents and polyester raw materials are used in the production of polyurethane elastomers and flexible polyurethane foams; esters made from BD are good additives for cellulose, polyvinyl chloride, polyacrylates and polyesters. plasticizer. BD has good hygroscopicity and flexibility and can be used as gelatin softener and water-absorbing agent, as a treatment agent for cellophane and other unused paper. It can also prepare N-methyl pyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, and also used to prepare vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, moisturizing agents for various processes, softness, adhesives and brighteners for the electroplating industry.

PTA is one of the important bulk organic raw materials, widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy. At the same time, the application of PTA is more concentrated. More than 90% of PTA in the world is used to produce polyethylene terephthalate (PET). It needs 0.85-0.86 tons of PTA and 0.33-0.34 tons of MEG to produce 1 ton of pet. Polyester includes fiber chip, polyester fiber, bottle chip and film chip. In the domestic market, 75% of PTA is used in the production of polyester fiber; 20% is used in the production of bottle grade polyester, mainly used in the packaging of various drinks, especially carbonated drinks; 5% is used in film grade polyester, mainly used in packaging materials, films and tapes. It can be seen that the downstream extension product of PTA is mainly polyester fiber.
Application:
PTA is mostly used in the production of polyethylene terephthalate (polyester). It is an important raw material for polyester fibers, films, plastic products, insulating paints and plasticizers. It is also used in dyes and other products' production.
1. Description: It is the raw material for making thermosetting resin, light curing epoxy resin coating, oil resistant coating and drying coating. Its copolymer emulsion is used for fiber finishing, fabric, leather and paper coating. Also used as wood, metal and other adhesives.
2. Typical recipes
Used as crosslinked monomer in acrylic emulsion. The amount of carboxyl-containing acrylic emulsion pressure-sensitive adhesive is L % ~ 2% of the total monomer mass, and the initial adhesion will be greatly reduced if it exceeds 3%. For emulsion adhesives without carboxyl group, the general dosage is not more than 5%. The crosslinking reaction temperature of MMAM alone is high, generally 120 ~ 170�ºC, and the addition of protic catalyst can reduce the crosslinking temperature. Acrylic acid (AA) can both provide hydrogen protons and copolymerize with acrylates, so MMAM should be used as a composite crosslinking agent with AA at a dosage of 3:2. Cross-linking agent HA can replace N- hydroxymethyl acrylamide, and does not contain formaldehyde.
3. Application scope
A. Can be used as crosslinking agent, widely used in fiber modified resin, processing dyes, plastic adhesives, soil stabilizers, etc.
B. Used for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agent.

Polyethylene terephthalate (PET), with the chemical formula (C10H8O4) n, is synthesized by exchanging dimethyl terephthalate with ethylene glycol ester or esterification of terephthalic acid with ethylene glycol, followed by condensation reaction to obtain dihydroxyethyl terephthalate. Belonging to crystalline saturated polyester, it is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It is a common resin in daily life and can be divided into APET, RPET, and PETG.
