A masterbatch is comprised of plastic or bio=polymer pellets that contain concentrated amounts of additives such as processing aids, colorants, anti-stats, light stabilizers, fillers, etc.
We specialize in Masterbatch production and our masterbatch is supplied in pure form. Masterbatches encapsulate the additive in a resin or liquid. This encapsulation reduces, or in most cases eliminates, the hazardous nature of the additive. It also removes the numerous potential hazards of handling powders.
The usual ratio of masterbatch to the base resin is 1 to 5 percent, saving you money, time and increasing safety.
We are one of the few who can offer a non-plastic masterbatch.

The world is evolving and the polymer industry has to make a rapid shift to a new situation where sustainability is a priority for governments, companies and consumers.
The European Union, Indian Govt and more than 60 nations globally are restricting the use of mono-use materials.
The vision for 2030 is to reduce the amount of plastics that go to the landfill.
Conventional materials, such as PE, PP or PS, have traditionally been used by the industry to produce containers and other plastic films that are obtained from fossil resources that, due in many cases, due to multi-material mixtures or to food contamination cannot be easily recycled.
Bio polymer can be processed in most co extrusion or monolayer lines. Being made from corn starch they can degrade and are compostable within 6 months of exposure to landfill.
They can be processed as carry bags, mailer bags, stretch films, hot and cold food packaging, shrink films, injection moulding, paper lamination, hygiene disposables, 3D printing etc.

Oxo-biodegradable has a tendency to degrade when it comes into contact with sunlight, heat and micro-organisms.
These are made of newly inventive additives that when mixed with raw materials and will cause the plastic to photo-degrade. It degrades thermally and chemically as litter in anaerobic and aerobic facilities.
It degrades to lower molecular weights as a result becomes rigid and fragmented until digested by the micro-organisms and then back to the basic elements of carbon dioxide, biomass and water.
Generally, in households, offices, hotels and hospitals are the places where maximum waste is generated. In order to organize the waste systematically, cheap, light, waterproof polyethylene bags are used.
Oxo-biodegradable plastic degrades due to exposure to the elements (sunlight, heat, and micro-organisms). Two years is an estimation based on the average conditions.

UV attack by sunlight can be ameliorated or prevented by adding polymer UV stabilizers, usually prior to shaping the product by injection moulding.
UV stabilizers in plastics usually act by absorbing the UV radiation preferentially, and dissipating the energy as low-level heat.
The chemicals used are similar to those in sunscreen products, which protect skin from UV attack. The effects of UV degradation on materials that require a long service life can be measured with accelerated exposure tests.
With modern solar concentrator technologies, it is possible to simulate over 60 years of natural UV radiation exposure on a test device in a single year.
CVI UV is a synergistic mixture of additives. It is a versatile light stabilizer with good extraction resistance, low gas-fading and low pigment interaction.
It is particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP films. It is used in tarpaulins, shrink films, greenhouse films, polycarbonate sheets, UV stabilizers prevent this damage and will also impede chalking.
These functional additives can either reflect or absorb UV light before it can begin polymer degradation and fade the product’s color.
The UV absorbers will absorb the light and dissipate its energy.

Antifog masterbatch is formulated to reduce or prevent formation of water droplets on the surface of the product by merging them and form the continues transparent layer in order to maintain the clarity of film.
Food packaging and horticulture firms are designed in such a way that prevent water droplet cloudiness, low volatility and also prevent yellowish effect along with negative effect over transparency and odor of the film.
The following factors are taken into consideration while the process take place: Thickness of the film and condition of the manufacturing process, Methods of production.
CVI anti-fogging treatments are used on plastic surfaces such as bags and plastic films.
Anti-fogging treatments, can be placed onto the surface of optically clear plastic products, or put into a masterbatch format to become an inherent part of the plastic, work by minimizing surface tension — which results in a non-scattering film of water instead of single droplets.
This works by altering the degree of wetting.

Antistatic masterbatch is formulated in order to eliminate the electric charges on the surface of the polymer.
Electric charges tend to cause many problems like attracting dust which ruins the clarity of film and surface finishing, or damaging electronic equipment.
Antistatic additives are used with all polymers in injection molded, extruded applications and blow molded.
It functions in molecular or multi -molecular layers and attract water molecules from the atmosphere. The water lowers the surface resistivity 109 to 1011 ohms.
Without antistatic additives, the surface resistivity of plastic is between 1012 to 1015 ohms.
Antistatic masterbatches are used in manufacturing of appliances and are used in washing machines, refrigerators etc.
These are also used in electronic products.
In order to achieve a higher conductivity, conductive fillers like carbon black, carbon fiber and powdered metal are added to the plastic.
• reduce or eliminate fire and flame
• halogenated and non halogenated grades
• available in pe, hd, pc, abs, eva base
Plastics are combustible as they are based on hydrocarbons. Flame retardant masterbatch is designed to delay the spread of fire in order to protect people and property. Flame retardants are categorized as follows:
Phosphorous compounds that form char. It hinders the release of combustible gases and acts as shield in order to protect the polymer from heat of flame.
Bromine Flame Retardant releases the active bromine atoms into the gas phases before the material reaches its ignition temperature and the chemical reactions quenches within the flame.
This prevents the spread of fire.
Inorganic compounds are used in large concentrations in order to achieve the desired results.
Flame retardants are used in numerous applications to reduce the risk of fire spread.
Some typical applications are Upholstered Furniture, Buildings, Cables, Transport (airplanes, ships, trains, cars), tarpaulins, industrial shrink films, home appliances, automotive parts, electrical parts, electronics.
It reduces the risk of endangering consumers even when the product gets damages or catches fire thus minimizing the risk and protection human life and health.

Generally, the manufacturers have to encounter with the problem of blocking of films. Anti block masterbatch is required to modify the surface characteristics of the polymer film by reducing blocking, facilitating handling and processing.
Blocking is the adhesion of two adjacent layer of the film. This problem is generally required to deal with polyethylene and polypropylene films. The blocking of adjacent layers of film occur due to the presence of Ven Der Waal’s forces between the regions of the film.
As the distance reduces between two layers the forces increase and end up with blocking.
This causes the hindrance in production process.
The use of masterbatches called “ANTIBLOCK” resolves two major problems often encountered in the film industry.
1 – The facilitation of rolling film coils. During film rolling, air bubbles can be trapped between successive spires which can cause small localised flaws. The coils thus manufactured are no longer cylindrical, and the film isn’t perfectly flat when it is unrolled.
2 – The “blocking” effect results from the adhesion developed between two smooth layers of film placed in contact with each other with polyethylene and polypropylene films, by a “CAST” or an “inflation” (BLOWN) process, even after lamination.

Slip masterbatch enhances the surface finishing of polymer by reducing the coefficient of friction (COF). It also maintains the optic properties like clarity, brilliance and transparency of film.
The thickness of film and the amount of slip agent must be reduced to maintain the same coefficient of friction.
We are providing the best quality material by which excellent lamination and metalizing properties, excellent printing ability, proper handling of goods in packing machines, smooth winding and unwinding of films, avoids cracking of sheets during processing etc. can be achieved.
It is recommended for many applications like film, sheet and injection moulding.
As slip agents, fatty acid amides (Oleamide, Erucamide and Stearamide) are normally used.
During processing they are solubilized in the amorphous melt, but as the polymer cools and crystallizes the fatty acid amides are squeezed out forming a lubricating layer at the polymer surface. The addition of slip agents can prevent film sticking and pulling helping to increase throughput.
