Composite glue plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are rich and diverse. This article will detail the upstream and downstream associated products of composite adhesives.

1. Upstream Associated Products

1. Natural rubber: Natural rubber is one of the main raw materials of compound rubber, which is made of latex secreted by rubber trees through coagulation, drying and processing. Natural rubber has good elasticity, wear resistance, tear resistance and processing performance, is an important basic material of composite rubber.
2. Synthetic rubber: Synthetic rubber is rubber made by chemical synthesis method. Common synthetic rubber includes styrene butadiene rubber, butadiene rubber, neoprene and so on. Synthetic rubber has excellent properties, such as oil resistance, acid and alkali resistance, high temperature resistance, etc., which can make up for the shortcomings of natural rubber in some aspects.
3. Filler: Some fillers need to be added to the composite adhesive to improve its physical properties and processing properties. Common fillers are calcium carbonate, carbon black, white carbon black, etc.
4. additives: the production process of compound glue also need to use some additives, such as antioxidant, accelerator, vulcanizing agent, etc., to improve the processing performance and use performance of the compound.

2. downstream related products

1. Tire: Composite rubber plays an important role in tire manufacturing, which can improve tire wear resistance, tear resistance, and aging resistance. Tires are the largest downstream application area for composites.
2. Hose: Composite glue can be used to make all kinds of hoses, such as oil pipes, air pipes, water pipes, etc., with good oil resistance, acid and alkali resistance, high temperature resistance and other properties.
3. Tape: Composite adhesive can be made into various tapes, such as cloth tape, paper tape, transparent tape, etc., with strong adhesion, good weather resistance, high tensile strength.
4. Seals: Composite glue can be used to make all kinds of seals, such as gaskets, sealing rings, sealing strips, etc., with good sealing performance and oil resistance, acid and alkali resistance and other properties.

In short, the compound glue in the chemical production of raw materials in the field of upstream and downstream related products are very rich, its wide range of applications, to promote the development of the chemical industry has an important role.
