上海What are the raw material options for blow molding products in Dalian?

Dalian blow molding products are plastic products with strong functionality, high production efficiency, and wide applicability. With the continuous advancement of technology and people's constant pursuit of quality, blow molding products will inevitably occupy an important position in future market competition. With the increasing awareness of environmental protection among people, the environmental friendliness of blow molded products has also received much attention. At present, some plastic product manufacturers have begun to try using biodegradable plastic raw materials to reduce environmental pollution. In the future, the greenization and recyclability of blow molded products will become the main trend in industry development.

The parameters of blow molding process include extrusion temperature, extrusion speed, inflation pressure, inflation time, etc. The reasonable control of these parameters is crucial to ensure the quality of blow molded products. In the production process, process parameters should be optimized according to different plastic materials and product requirements to ensure the quality of the preform and the effect of blow molding.

What are the raw material options for blow molding products in Dalian?

The raw materials for blow molded products mainly include plastic materials such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Different types of raw materials correspond to the characteristics and uses of different blow molded products.

Polyethylene is mainly divided into high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE). HDPE has high hardness and heat resistance, making it suitable for producing blow molded products with high requirements, such as water pipes, oil drums, etc; LDPE has good flexibility and cold resistance, suitable for making packaging films, food bags, etc; LLDPE is a new type of plastic between HDPE and LDPE, with good toughness and tear resistance.

Polypropylene is a commonly used blow molding material, mainly divided into homopolymer polypropylene (PP) and isolation polypropylene (HDPP). PP has good transparency and high temperature resistance, suitable for making food packaging boxes, beverage bottles, etc; HDPP has higher rigidity and tensile resistance, making it suitable for making cosmetic bottles, ice cream cups, etc.

Polyvinyl chloride is mainly used to make hard blow molded products, such as water pipes, cable sheaths, etc. According to different additives and processing techniques, polyvinyl chloride can be made into two types of blow molded products: soft PVC and hard PVC.

There are various types of blow molded products that can be customized according to different needs. For example, food packaging boxes, cosmetic bottles, pharmaceutical bottles, chemical containers, etc. Through the selection of plastic raw materials and the blending of additives, blow molded products can have characteristics such as high temperature resistance, low temperature resistance, and UV protection to meet the diverse demands of the market for products.

The plastic materials used in most blow molded products have good corrosion resistance and can resist the erosion of chemicals such as acid, alkali, salt, etc. This enables blow molded products to be widely used in industries such as chemical, food, and pharmaceutical, ensuring the quality and safety of products during storage and transportation.
