1, 4-butanediol is widely used. In the United States and Western Europe, more than half of it is used in the production of tetrahydrofuran, followed by the production of γ-butyrolactone and polybutylene terephthalate, which is a rapidly developing engineering plastic; 1, 4-butanediol is used as chain extender and polyester raw material in the production of polyurethane elastomers and soft polyurethane foams. The esters obtained from 1, 4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylate and polyester. 1, 4-butanediol has good hygroscopic flexibility and can be used as a gelatin softener and water absorbent, as a treatment agent for cellophane and other non-paper. N-methylpyrrolidone, n-vinylpyrrolidone and other pyrrolidone derivatives are also used in the preparation of vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, humidifiers, softeners, adhesives and brighteners for the electroplating industry.

The factories we cooperate with have large shipments of 1, 4-butanediol (BDO), rapid delivery and fresh production dates. This can help some suppliers and buyers to buy high-quality 1, 4-butanediol (BDO) with fresh production date from us. We will not sell products near the expiration date to customers like others, because transportation takes time, so our delivery cycle is usually arranged in 10-15 days, and orders under 10 tons will be shipped within 10 days.

Toxic. When attached to the diseased or injured skin or consumed, it initially exhibits anaesthetic effects, causing specific pathological changes in the liver and kidneys, followed by sudden death (without prolonged latency) due to central nervous paralysis. Production equipment should be sealed to prevent leakage, and operators should wear protective equipment. Persons with skin wounds are strictly prohibited from contact with this product.
