Extrusion blow molding machines have many applications in the chemical industry, and the following are some of the main aspects:

Manufacturing of packaging containers for chemical products

Plastic drums: Different specifications of plastic drums are commonly used in the chemical industry to hold various liquid and solid chemical products. For example, a 200L plastic drum can be used to package coatings, resins, lubricants, etc., while a 220L double L ring chemical packaging drum is suitable for hazardous chemicals, acid and alkali substances that require high packaging sealing and strength. Extrusion blow molding machines can efficiently produce plastic barrels with stable quality and good sealing, ensuring the safety of chemical products during storage and transportation.

IBC Bulk Container: Large IBC tanks can hold up to 1000 liters or even larger capacity and are commonly used for packaging large quantities of liquid chemical raw materials, intermediates, and finished products, such as diluents, solvents, plasticizers, etc. in chemical production. The extrusion blow molding process can produce IBC tanks with sufficient strength and corrosion resistance, meeting the needs of large capacity packaging and logistics transportation in the chemical industry.

Thin walled containers: For some chemical products that are sensitive to packaging costs and have packaging weight requirements, such as some household cleaning agents, low-dose chemical reagents, etc., extrusion blow molding machines can produce thin-walled plastic containers. By precisely controlling the process parameters, while ensuring the strength and sealing of the container, the wall thickness of the container can be reduced, thereby saving raw material costs and transportation costs.

Production of chemical pipelines and fittings

Plastic pipes: Chemical production requires a large number of pipelines to transport various fluid media, such as corrosive liquids, gases, etc. Extrusion blow molding machines can produce plastic pipes made of materials such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), etc. These pipes have the advantages of corrosion resistance, wear resistance, light weight, and easy installation, and are widely used in chemical enterprises’ water supply and drainage systems, acid and alkali transport pipelines, ventilation ducts, etc.

Pipe fittings manufacturing: In addition to pipes, matching fittings such as elbows, tees, and tees are also indispensable components of chemical pipeline systems. Extrusion blow molding machines can produce various specifications and shapes of plastic pipe fittings by replacing different molds, ensuring more flexible and reliable connections and layouts of chemical pipeline systems.

Packaging and protection of special chemical products

Aerosol cans: Some chemical products such as aerosol cleaners, lubricants, insecticides, etc. need to be packaged in aerosol cans. The extrusion blow molding machine can manufacture high-strength and pressure resistant containers that meet the requirements of aerosol cans, ensuring that the compressed gas inside the can can evenly spray the contents during use, while ensuring the safety and stability of the can body.

Moisture proof and oxidation resistant packaging: For some chemical products that are prone to moisture and oxidation, such as certain fine chemical raw materials, electronic chemicals, etc., vacuum packaging containers produced by extrusion blow molding machines or plastic packaging with barrier properties can be used. By extracting air from the container or using multi-layer co extrusion blow molding technology to produce packaging materials with barrier layers, it effectively prevents the influence of external moisture, oxygen, etc. on chemical products, extending the shelf life and service life of the products.

Production of chemical equipment components

Plastic liner: In some chemical storage equipment, such as water storage tanks, reaction vessels, etc., plastic liners are often used to enhance the corrosion resistance and impermeability of the equipment. The extrusion blow molding machine can produce large plastic liners with good integrity and no welds, which can effectively avoid leakage risks and improve the service life and safety of the equipment.

Equipment casing and protective components: Some equipment casings, protective covers, operating platforms, etc. in chemical production sites can also be made of extruded blow molded plastic parts. These plastic components have the characteristics of light weight, corrosion resistance, and good insulation performance. They are not only easy to install and maintain, but also reduce the overall weight and manufacturing cost of the equipment, while improving the safety of the production site.
