In the field of chemical production raw materials, the upstream and downstream related products of sealants mainly include the following categories:

1. Upstream raw material

The main raw materials for the production of sealants include polymers, fillers, plasticizers, etc. Among them, the polymer is the main component of the sealant, and the commonly used polymer includes rubber, plastic, etc. Filler is used to improve the hardness, strength and other properties of the sealant, commonly used fillers are calcium carbonate, talc and so on. Plasticizers are used to adjust the flexibility and fluidity of the sealant. Commonly used plasticizers include phthalic acid esters, phosphoric acid esters, etc.

2. Downstream product

sealant In the production process, it is often necessary to cooperate with other chemicals to create a more complete and reliable sealing system. Therefore, the downstream products of the sealant mainly include the following categories:

(1) Sealing gasket: The sealing gasket is a component used to fill the gap between the connecting parts such as flanges and pipes to achieve the sealing effect. Sealants are often used in conjunction with gaskets to improve sealing performance.

(2) sealing tape: sealing tape is a kind of adhesive tape material, often used for pipeline, container and other equipment sealing and repair. The sealant can be used in conjunction with the sealing tape to improve the sealing effect and construction efficiency.

(3) Sealing coating: Sealing coating is a material that is applied to the surface of the equipment and can form a dense coating. The sealant can be used in conjunction with the sealing paint to increase the sealing and corrosion resistance of the equipment surface.

In short, the upstream and downstream related products of sealants cover many fields, including raw materials, production equipment, auxiliary tools, and supporting products. These products are used in conjunction with sealants to improve sealing performance, construction efficiency and production efficiency, and to support the development of chemical production.
