What factors should be considered when purchasing granule adhesive?

Plastic products have always had widespread applications in people's daily lives, and their use in various aspects of human life is unavoidable.

Naturally, with the increase in demand, the market for companies active in this field becomes competitive, and one of the issues that engages manufacturers is the purchase of suitable granules as raw materials for their products. Considering the fluctuation in currency exchange rates, obtaining accurate and real-time information about granule prices is crucial, along with adhering to some important points when purchasing these materials.

In this article, we will discuss four golden tips for purchasing granules, which, if followed, can lead to a successful purchase of high-quality granules at reasonable prices. As you know, the first step in buying any product is gathering information about it. Consumers of granules also have concerns about where to inquire about granule prices, what factors to consider when purchasing, and which granules are suitable for their manufacturing needs. Join us as we delve into these aspects.

1) Granule Price; one of the most crucial factors

The price of polymer raw materials is influenced by currency exchange rates and market fluctuations. As you know, the exchange rate (dollar) has significant fluctuations these days, making it challenging to quote the price of these products daily.

Since granule prices are usually announced daily based on the market price, commodity exchange rates, and the offerings of petrochemical companies, prices tend to change daily. Due to the competition among buyers, prices may even change several times during the day. These daily fluctuations, sometimes hourly, and the lack of an official source for announcing unit prices create significant challenges for buyers.

Different suppliers and individuals offer different prices, and the buyer always wonders whether the price is fair and accurate. It is recommended to contact several companies in this field before making a purchase, inquire about the prices, and choose the best price and sales conditions.

Bespargostar Aria Engineering Company is one of the reputable companies known as a supplier of various polymer granules in Iran. You can contact the experts of this company for a price inquiry and stay informed about the prices of their products. Unlike many granule-producing companies whose product prices fluctuate moment by moment or weekly, this company has tried to present its price changes at specified intervals, considering market trends.

2) Intended Use; the product for which you are purchasing granules

The buyer should purchase the relevant granules based on what is intended to be produced. Therefore, paying attention to the product for which the granules are intended is a crucial factor in selecting the desired granules.

For example, different grades of polyethylene and polypropylene granules are used for producing plastic products such as stationery, kitchen utensils, wire and cable coatings, etc. Depending on specific applications and different production methods, various grades of injection-molded polyethylene granules and polypropylene granules for textile or chemical use are employed.

3) Granule Supplier; from whom to buy?

The supplier from whom this raw material is purchased must be reputable and have a recognizable name and brand. Finding such a supplier can be accomplished through inquiries from acquaintances, internet searches, finding reputable websites, and various advertisements. Since a significant expense is involved in obtaining the necessary granules, take some time and, with a bit of search and research, choose the best option.

4) Type of Consumable Granule; On-Grade or Off-Grade?

Granules are divided into two categories: On-Grade and Off-Grade. Off-Grade refers to products that do not conform to petrochemical standards in terms of visual, physical, and mechanical properties.

In contrast, products that meet these standards are called On-Grade. Off-Grade products are further classified into Off-Grade 1, Off-Grade 2, and Off-Grade 3, with quality differences among them. The closer the granules are to On-Grade properties, the higher their price.

Considering these factors and the sensitivity of the manufactured product (qualitative, hygienic, environmental considerations, etc.), you can choose to use either type of granule. Sometimes, high sensitivity is not required, and a relative drop in quality can be overlooked. Therefore, to reduce production costs, one can move towards Off-Grade products. Always keeping in mind the following point can help in selecting the type of granule:

"Maintaining the granule price at a reasonable level (neither too high nor too low) plays a crucial role in the success of productions. In addition to maintaining the quality of the granule, its physical properties, such as strength, qualitative characteristics, elasticity, etc., must also be preserved."


Many granules produced in Iran are recycled granules, and their quality significantly differs from On-Grade materials. Some manufacturers, like Bespargostar Aria, use grade 1 petrochemical powder to produce their granules. The quality of these granules falls between Off-Grade 1 and On-Grade.


Market turmoil and sharp price fluctuations in any industry create challenges for buyers. The polymer product market is no exception to this rule and has consistently puzzled buyers. Manufacturers, before purchasing granules, can make a successful purchase of their desired granules by spending a little time and considering the points discussed in this article. Adhering to these golden tips in granule purchases can significantly reduce uncertainties.
