In the plastic product manufacturing industry, various additives are used to improve the properties of the final product, one of the most widely used of which is masterbatch filler.

Due to the presence of minerals in its structure, this masterbatch creates unique characteristics in products, and along with increasing the quality of the product, it reduces its cost.

In this article, we will introduce you to this widely used additive and examine its benefits in the plastic industry.

What is a filler masterbatch?

Masterbatch filler is an additive based on PE, PP, and PS, consisting of 20-80% of minerals. The presence of minerals in the filler masterbatch makes the final product acquire unique characteristics and increases its quality when combined with the plastic product. Adding masterbatches to plastic products can create properties such as stability and heat stability, high resistance, high hardness, etc. Using this masterbatch is an effective solution to improve the physical and chemical properties of the final product and helps to reduce its price.

Types of masterbatch filler

Masterbatch filler is produced in different types, each used according to the polymer base of plastic products. The types of filling masterbatch are:

Masterbatch talc

Talcum powder with a semi-transparent appearance and white color is added as a filler masterbatch to polymers such as polypropylene. This additive increases the resistance and thermal hardness of the product. It also prevents them from drying out. This filler is usually used for household appliances, cars, etc.  The following can be mentioned among the advantages of this masterbatch filler.

• The property of being soft
• High chemical resistance
• Increased tensile strength
• Low electrical conductivity
• No explosion and ignition
• Improving the hardness and strength of the product
