Blending polymers are one of the efficient and cost-effective methods to produce new polymer materials with unique properties. The final properties of the made blend are influenced by various factors like the nature of the blend’s constituent materials, the thermodynamic affinity of the constituents to each other, the percentage composition, the viscosity of the components, and the composition of the feed, etc
In recent years, quality control standards have changed in the interior parts of the car as well as the exterior. This issue is one of the reasons why PP is used in making car dashboards, car door covers, etc.
Products based on pure polypropylene usually have practical limitations in producing car’s interior parts due to their weaknesses in mechanical properties such as impact and scratch resistance. Therefore, specially designed polypropylene-based mixtures with particular additives can simultaneously increase the modulus, and impact resistance is used to produce these parts.
Scrachem is a PP mixture with minerals and special additives that create excellent anti-wear properties. Scrachem with good hardness and surface strength, Low thermal expansion coefficient and shrinkage, high flexural modulus, and tensile strength, and higher impact resistance has the best performance for the production of the interior and exterior parts of the car.
Polyolefins have received much attention in food packaging due to their unique properties.
The most crucial goal primarily considered in the packaging of food products is to increase the product’s shelf life or its useful life. Currently, polymers are used extensively in the food packaging and container industry due to their low specific weight, high plasticity, less energy consumption for production, and the ability to improve their properties by adding minerals and additives.
Although, the main weakness of this category of polymers is their fragility and impact resistance, especially at low temperatures of food storage.
Polytaf is an impact-resistant polymer alloy based on polyolefins, which simultaneously creates high impact resistance, suitable for producing sheets and parts used in food packaging containers.
The unique properties of PC/ABS blends have led to their use in diverse and extensive applications such as electrical, automotive, home appliances, and sports equipment.
Flame retardancy is of great importance in most of the mentioned cases, especially in the electrical industry, which is the most used area of PC/ABS blends.
Polyflame is a blend of PC and ABS with high impact resistance and halogen-free materials, with flame retardancy properties at the UL94-5VA level.
The use of carbon black (CB) in polyethylene (PE) pipes is known to be the most economically effective measure against exposure to thermal and photodegradation.
To gain optimum performance from the carbon black addition, CB particles being utilized at required concentrations need to be well dispersed and distributed among the natural pipe resin matrix, as CB particles are known to dictate the performance of the polyethylene.
Polycoat can cover all oil and gas lines using suitable mechanical properties to resist puncture and tearing, high ESCR in a long time, and suitable absorbability with polyethylene maleic layer.
Geochem is a black masterbatch based on polyethylene with double peak molecular weight distribution, excellent carbon black(CB) distribution, UV resistance, and high ESCR.
This product can use in all geomembranes by taking advantage of suitable mechanical properties such as puncture and tear resistance, high ESCR in extended periods, and good processability.
The good rheological properties for production in different processes, such as blow molding and cast molding, are essential in preparing a black polyethylene masterbatch for producing geomembranes. Furthermore, having the physical and mechanical properties defined according to the standards is necessary to achieve the desired efficiency, especially in the long term. The most critical parameter determining the lifetime of geomembranes is the resistance to environmental stress crack resistance (ESCR). High ESCR in high molecular weight polyethylenes is achieved when two-peak molecular weight distribution is established in the main structure of polyethylene.
Crayochem is designed to create two properties of biodegradability and the desired color in the final product.
It is made by using a certain percentage of dyes and biodegradable additives in a polymer carrier.

Flame retardant colored masterbatch with PP carrier for producing non-woven textiles.
ChemovenFR, while creating a suitable melt flow index for the non-woven production process, will also create flame retardant properties. In addition to the mentioned cases, molecular weight control in terms of distribution under reactive extrusion conditions in the presence of peroxide and flame retardant agents is considered a feature of this product technology..
Electrical Conductive Compound
Chemolec is a semi-conductive nanocomposite with a polyolefin carrier. According to the final requirements, It is produced with different polyolefins grades. As a result of adding conductive nanoparticles such as MWCNT and CB to Chemolec, This product has antistatic properties. At the same time, it maintains the carrier polymer’s physical and mechanical properties and processability.
Ultraviolet (UV) radiation is defined as that portion of the electromagnetic spectrum between x-rays and visible light, i.e., between 40 and 400 nm. UV stabilizers are used to solve the degradation problems associated with exposure to sunlight.
Agrichem is a state-of-the-art solution to provide superior UV protection by giving unique formulations to suit our customers’ requirements according to a particular location’s climatic conditions.
White masterbatch is a mixture of polymers with white pigment and additives to create a white coating and color. An essential additive in the production of white masterbatch is titanium dioxide.
Filler masterbatch is a combination of CaCo3, primary polymer and special additives. These masterbatches produce by a different polymer such as polyethylene, polypropylene, and polystyrene.
Color masterbatch is a concentrated mixture of base polymer with organic or inorganic color pigments. By adding a small amount of color masterbatch, the desired color can be achieved in the final product.
An additive masterbatch is a concentrate in granule form for modifying thermoplastics. Additive masterbatches consist of one or more additives and a polymer-specific carrier resin.
