Optimization of the production process
No impact on optical properties
No negative impact on mechanical properties

Anti-static additives
The generation of electrostatic charges during friction or material contact poses a challenge that can disrupt production processes and affect the functional properties of plastic products.

Prevention of pellet static in feeders, dosing systems, and during storage
Protection against electrostatic discharges
Possibility of combining with color masterbatches and other additives (combi-batches)

Antioxidant additives
Plastics are susceptible to oxidation caused by both light exposure and elevated temperatures. As a result, over time or even during processing, plastics may lose their mechanical properties and their surface may deteriorate visibly. Antioxidants effectively counteract these phenomena, protecting the material during both processing and end use.
Prevention of mechanical property loss
Protection against yellowing, hazing, surface cracking, and gloss loss

Elimination of the “shark skin” effect
Reduction of gel formation
Improved surface quality
Gloss enhancement
Reduction of pressure and temperature in the extrusion process
Easier color changes

UV stabilisers
Plastics exposed to outdoor conditions are subject to the effects of weather phenomena, primarily sunlight. Natural sunlight causes irreversible degradation of polymers. Ensuring long-term usability of the product requires the use of UV stabilizers, which protect the material from premature degradation.
Protects against UV degradation, extending the usability and lifespan of products.
Helps maintain the color and appearance of the product.
Reduces the formation of surface cracks.
Can be combined with colorants and other additives to create combi-batches.

UV Barriers
Sunlight can lead to the degradation of sensitive products such as food, cosmetics, or chemical liquids.
UV barriers effectively protect the contents of packaging by blocking harmful UV radiation, ensuring longer shelf life and the preservation of product properties.
Ensuring excellent optical properties
Protection of package contents against UV degradation
Enabling the use of transparent packaging
Safe solutions without benzotriazole
Gloss enhancement
Reduction of pressure and temperature in the extrusion process
Possibility of giving the packaging a blue or green tint through the use of a combibatch

Chemical foaming agents
Foaming agents decompose under high temperature, releasing gas bubbles. This process leads to the formation of a porous structure within the plastic, affecting its physical properties such as lightness and insulation. By using appropriate foaming agents, it is possible to obtain materials with the desired characteristics, tailored to specific production requirements.
Weight reduction of up to 50%
Cycle time reduction of up to 50%
Elimination of sink marks and shrinkage
Higher stiffness-to-weight ratio
Reduction of carbon footprint

Flame retardants
Flame retardants, also known as antipyrenes, are specialized chemical additives used to reduce the flammability of plastics. Their application increases the fire resistance of materials, contributing to improved safety across various industries.
Slowing down the fire propagation process
No smoke emission during combustion
Safe halogen-free and economical halogen-based solutions
Possibility of combining with color masterbatches and other additives (combi-batches)

Desiccant additives
Plastics, both virgin and recycled, may be sensitive to the presence of moisture, which can cause issues during the processing of “wet” material. The use of moisture absorbers effectively eliminates this problem, ensuring an optimal production process and preserving material quality.
Optimization of raw material handling and processing
Protection of metal machine parts against oxidation
Facilitation of processing lower-grade plastic materials
Enables the use of moist materials stored in outdoor conditions

MFI modifiers
The melt flow index (MFI) is a key parameter that defines the processing properties of plastics.
For materials with low MFI, modifiers enable an increase in this value and improve processing flowability.
Their use facilitates the adaptation of the material to production process requirements, enhancing both efficiency and product quality.
Allows for an increased share of regranulates in the processing, resulting in reduced production costs

Antifog
“Fogging” of plastic films is a condensation phenomenon in which small water droplets form on the surface of the material. This typically occurs due to temperature differences between the inside and outside of an enclosed space. Antifog additives effectively prevent this effect, ensuring clarity and transparency of the film under various conditions.

Prevention of moisture accumulation on polyolefin films
Maintaining good light transmission in greenhouse films
Preserving food freshness in packaging
No impact on optical properties

Antiscratch
The appearance of many products is crucial for the end user, and polymer surfaces and components are often prone to scratching. Rough surfaces attract dust and dirt, which not only worsens aesthetics but also reduces hygiene and mechanical performance. Antiscratch is an innovative solution that effectively protects products from scratches, ensuring a smooth surface that is easier to clean, thereby extending durability and improving functional quality.

Impact modifiers
Impact is the measure of crack resistance when the dynamic load is used. It is an important parameter which is controlled in particular in the production of regranulates. The use of impact modifiers makes it possible to increase this parameter, even in the case of low-strength raw materials.
Improvement of tensile strength
Improved resistance to cracking and thermal deformation

Optical brighteners
Optical brighteners are chemical compounds capable of absorbing ultraviolet (UV) light and re-emitting it as visible light in the blue-violet range. This effect neutralizes the yellowish tones naturally present in some plastics, making the material appear whiter and fresher.
