Additives give plastic products durability and additional desired properties such as antistatic, slip, durability, non-flammability properties, and so on.
The distinctiveness of Vilkritis is the creation of a new, unique formulation, the provision of a small amount of test product, testing in an in-house laboratory within an especially short period of time, and the provision of recommendations according to the customer’s preferences for raw materials and the desired characteristics of the future product.
ColibriPlast additive groups
Clarifying additives are used to clarify polypropylene. They also strengthen the mechanical properties of polypropylene and increase the recycling temperature.
Antioxidants are recommended for all production processes. They help to stabilise the polymer, and also provide thermal stability during the polymer recycling process.
MOISTURE ABSORBING ADDITIVES
Moisture absorbing additives make it easy and economical to remove moisture and gas from recyclable plastic.
Flame retardants are added to polymer compositions according to the flammability requirements. Flame retardants are designed for the relevant desirable flammability class according to European standards.
Anti-blocking additives are used to prevent film layers from sticking to each other or forming a roll in the film production process. Anti-blocking additives that do not affect transparency help to easily ruffle the surface of the product without losing its transparency properties.
Process stabilisers smooth, flatten, and polish the surface of the product, reduce or eliminate superficial defects in products (especially in films), and reduce friction, enable the processing of highly viscous polymers, and reduce or help to entirely prevent the build-up of deposit in production installations during the process.
Slip additives help to reduce the coefficient of friction (COF) in films and other products.
Strengthening additives increase product resistance and prevent breakage.
Foaming additives enable maximum weight reduction of the polymeric product.
UV-absorbing additives and UV stabilisers absorb harmful UV rays and diffuse them into heat energy. They are easy to use and particularly effective on products thicker than 100 microns.
Transparency-enhancing additives help improve the visual properties of polypropylene by increasing transparency and gloss in product surface.
Anti-sedimentation additives speed up and facilitate extrusion or injection processes.
Anti-fog additives prevent the formation of water droplets on agrofilm or food packaging, and protect fruits and plants from moisture.
Cleaning additives are used for the quick cleaning of extruders or casting installations when switching from one polymer or colour to another.
BEVERAGE BOTTLE STOPPERS ADDITIVES
Additives facilitating bottle stopper opening are specially designed for beverage bottle stoppers.
Antistatic additives remove static charge inherent in all polymers. They facilitate the production process by reducing surface resistance and reducing dust accumulation on the product.
Antibacterial additives are additives of a broad spectrum that contain antimicrobial or antibacterial ingredients, which kill microorganisms and give a lasting antimicrobial effect.
TRANSPARENCY AND STABILISING ADDITIVES
Transparency and stabilising additives shorten production time and give rigidity, homogeneity and integrity.
Anti-mould additives contain mould-killing ingredients.
MATT EFFECT ADDITIVES
Matt effect additives create a matt finish on the product.
Anti-slip additives increase friction and prevent slipping.
Fragrance additives are used in cosmetics and household products.
Gloss additives help to improve visual properties, give gloss and a polishing effect.
MOULD RELEASE ADDITIVES
Mould release additives help to prevent parts from sticking to the mould in injection moulding and thermal moulding.
LASER SCANNING ADDITIVES
Laser scanning additives give the product properties that allow the engraving of the final product to be seen under special lighting conditions.
Anti-laminate additives prevent LDPE or LLDPE shrink film from sticking to packaged products or PE.
HYDROLYSIS PROTECTION ADDITIVES
Hydrolysis protection additives extend the lifespan and durability of products that are sensitive to hydrolysis, such as polyesters, biopolymers, synthetic and plant esters, or polyurethane.
Flow modifiers increase the melt flow index of the polymer.
Anti-corrosion additives protect packaged components from surface corrosion.
Infrared blockers protect against the long-term harmful impact of sunlight.
Conductivity additives enhance the electrical and thermal conductivity of composite materials.
PET VISCOSITY-ENHANCING ADDITIVES
PET viscosity-enhancing additives are designed for films and containers.
LIGHT DIFFUSION ADDITIVES
Light diffusion additives increase the transparency of the final product.
Anti-scratch additives are used to prevent the occurrence of scratches on the final surface of the product.
Mixing additives facilitate easy mixing of various components during the process.
BOPP additives improve the properties of BOPP film, such as heat stabilisation, non-slip protection, protection against environmental effects, etc.
Fillers are used in pipe, film, and other polymer recycling processes. These are calcium carbonate or talc masterbatches, which can be a great solution to improve the mechanical properties of the product, reduce deformation and cut production costs, while maintaining high quality.
The distinctiveness of Vilkritis is the choice of a filler that best suits the production process and the product, according to the customer’s assignment or product requirements. If necessary, a new, unique formulation is designed, some amount of test product is made, testing is conducted in the in-house laboratory and the customer is given recommendations. Fillers can also be used in products that come into direct contact with food.
