Types of granules in the plastic industry

Granule has different types and is named depending on the various applications it has in different sectors of the industry. The basis of the naming of granules can be their use (pipe granules, film granules, etc.), use in different production methods (air granules, injectable granules, etc.), chemical composition (polyethylene, polypropylene, etc.) or polymer structure (polypropylene granules). heavy ethylene, light polyethylene granules, etc.). In the meantime, the injection granule is the granule used in the injection molding method. By buying injection granules, you can produce all kinds of plastic products through the injection process and produce these products according to your needs.

Injectable polyethylene granule: One of the most widely used types of injectable granules in the market is polyethylene granule. This granule is made from first grade polyethylene powder. This powder has unique properties and excellent quality, but the cost of using it is high. However, it is possible to produce this granule from recycled materials, but the quality of these granules is lower, and this issue causes the price of injectable granule to decrease. Recycled granules are used to produce products that are not highly sensitive. Heavy polyethylene and light polyethylene are the most important types of polyethylene.

Injected heavy polyethylene granule: Injected heavy polyethylene or heavy injected granule is one of the granule grades that has a high molecular weight. This product has high hardness, good chemical resistance, low permeability and dielectric properties. This type of granule is in such a way that its properties increase as the density increases.
Injected heavy granule is made and used in different grades. Each of these grades has unique features and therefore has different uses. This granule is mainly used in the production of directional tape, woven bag, pipes, films, bulky industrial containers, etc.

Light polyethylene granule: linear light polyethylene granule is a group of injection granules that It has low density and low pressure method is used to produce them. Due to its short side branches and low density, this grade has good elasticity and tensile strength. For this reason, it is considered as one of the widely used grades for the production of polyethylene or nylon and nylon films. This granule has good processability and shows high impact resistance. Also, its resistance to chemicals is high. The price of injectable granule, which is in this classification, is low and this grade of granules has a low price.

Injectable polypropylene granule: Polypropylene granule is one of the grades of injectable granules that can be converted into any shape. did This problem has caused this granule to be widely used in the plastic industry. One of the most important features of this granule is its light weight. Also, the price of injectable PP granules is low in this category. The application of this grade is in the packaging industry. This granule is also used in the production of plastic toys, bottles, wire covers, water and sewage pipes, and medical equipment.
