What is Barite Masterbatch?

Barite masterbatch is an additive material that, when added to a plastic product, reduces water absorption, increases density, and decreases deformation against high temperatures. In general, barite has a unique property of insulation and provides remarkable strength and durability in polymer products. This masterbatch is made of powdered mineral barite, which has a hard texture and is available in white and gray shades. Typically, barite powder is combined with PVC, PS, and ABS masterbatches during use to achieve the desired results.

Characteristics of Barite Masterbatch

This material has suitable insulating capabilities, which is the main feature of this product that we will discuss further.

Increased product density: Barite increases the volume and density of the final product and is usually used for making heavy parts and vibration-resistant insulation.

Radiation insulation: This material has the ability to resist certain harmful radiations, such as X-rays, and prevents their penetration into the product. This feature is mostly used in the production of medical devices.

Sound insulation: This material can block sound vibrations and is very suitable for making sound-insulating parts.

Structural integrity of the product: Barite masterbatch can maintain the original shape and structure of the product during the manufacturing process and prevent its destruction under high heat and temperatures.

Applications of Barite Masterbatch

Medical industry: Used in the production of equipment and special shields to prevent dangerous radiation.

Automotive industry: This material is used to reduce machine noise and increase the weight of the vehicle to maintain its balance.

Construction industry: Barite is used to reduce outside noise and prevent sound from escaping from inside while constructing sound-insulating rooms or walls.
