KONSPEC offers antioxidant masterbatches, that are marketed under the brand name of "AOKON" to suit particular use. These master batches are formulated exclusively for the specific needs of polyolefins, styrenics, etc. with different loadings of active ingredients.

Need of Anti Oxidant for polymer Processing

The selection of antioxidant should be carefully done keeping into consideration all the critical aspects. All the polymeric materials undergo thermal degradation during the processing at elevated temperature, presence of atmospheric oxygen. Degradation of polymers causes in form of :

• Changes in color
  
• Detrimental effects on Physico Mechanical Properties
  
• Long term aging
  

Polymers immensely find application in long term aging usages which includes automotive components, furniture, electronic goods, appliances & parts etc. During the processing, polymers need the protection of outdoor exposure. For this purpose, antioxidants are added to polymers for protecting them against thermal degradation process. Application of antioxidants is increasing and most necessary in a variety of usages.

Types of Antioxidants

We offer 2 types of antioxidants namely primary antioxidants and secondary antioxidants. These antioxidants are briefly mentioned as follows:

Primary Antioxidants:

These antioxidants are free radical scavenger and prevent degradation by destroying free radicals generated during the degradation of Polymers. Examples of primary antioxidants are hindered Phrnois, secondary are amines.

Secondary antioxidant:

These secondary antioxidants decompose the hydeogeroxide formed during the reaction of primary antioxidant with free radicals and hence are used synergically with primary antioxidants. The examples of secondary antioxidants include Phosphates, Sulphites, Thioesters and many more.

Application Areas:

KONSPEC offers a wide range of AOKON Masterbatches for the following applications:

• Melt Stabilization of polypropylene
  

Polypropylene is sensitive to oxidative degradation owing to the tertiary hydrogens in its structure. Chain scission is the primary result of the oxidative degradation mechanism producing lower molecular weight resin with enhancement in melt index & lower physical properties.

• Melt stabilization of Controlled Rheology ( CR ) PP
  

Controlled Rheology (CR) is the term used to indicate that the PP has been subjected to post polymerization compounding process, that uses a peroxide cracking agent to modily the molecular weight distribution. They increase the melt flow and PP resin properties for applications like fiber spinning and injection molding. The selection of antioxidant is of considerable significance to have an effective control on the melt stabilization of controlled rheology PP. Antioxidant also prevents further increase in Melt Flow due to the peroxide cracking agent.

• Melt stabilization of HDPE / LLDPE
  

In contrast to PP, the melt index of HDPE/ LLDPE decreases during the multiple extrusion. Studies reflect its normal cross linking mode of degradation. The excellent melt stabilization activity of antioxidant is achieved through careful selection of antioxidant. Antioxidant should also provide efficient control on the color that is yellow index of Polymer during multiple passes.

• Polypropylene fibers
  

The Polypropylene fibers tend to undergo gas yellowing owing to the reactivity of nitrogen oxide generated by combustion of natural gases. Also the extraction of additives of the fibers by lubricant components in the spin finish etc.

'KONSPEC' manufacturers best quality UV stabilizer masterbatches, that are supplied under the brand name 'UVKON'. These master batches are used for PP Fibres, rotational molding, green house, high density and PP consumer application, automotive applications and in LDPE Films.

U.V. Masterbatches for PP Fibres :

We offer UV Masterbatches for PP fiber applications. PP Fibers are one of the most colorfast & naturally stain resistant fibers available. These characteristics make them ideal for residential as well as industrial applications. The PP fibers find usages for :

• Outdoor carpets
  
• A wings
  
• Umbrellas
  
• Interior automotive fibers
  

U.V. Master batches for rotational molding

We offer UV stabilizer MB based on HALS for rotomoulding application and active ingredients of masterbatch is sanctioned by FDA and BGVV. Rotomoulded tanks are mainly used in outdoors for extended periods and they are exposed to maximum UV rays. Apart from this, they also come in contact with water and have to be necessarily UV Stabilized. The HALS based UV stabilizers are used in maintaining the physical and surface appearance of roto moulded products for enhanced service life.

U.V. Stabiliser masterbatch for green house

The UV stabilization of agricultural films is of utmost importance as these films undergo most extreme weather conditions and different agricultural chemicals including pesticides, etc. We provide special grade of UV stabilized masterbatches for the stabilization of green house / agricultural films, which are based on the high molecular weight Polymeric HALS UV

Stabilizers with or without pesticide resistance depending upon the clients' requirement. These masterbatches also provide stabilization thermal against oxidation during the processing of these films.

U.V. Masterbatches for high density and Polypropylene Polyethylene consumer application

We manufacture and supply U.V. masterbatches for high density & PP consumer applications. These high density polyethylenes are widely used in consumer application, where appropriate UV stabilization is necessary to ensure product durability. Some application includes the following:

U.V. Stabilizer masterbatch for LDPE Films

Low density polyethylene is a comparatively inexpensive and general purpose commodity material, which is used for outdoor purpose. This material is used in shrint wrap's industrial film and tarpaulins is necessary for the endurance of product.

We have developed a series of UV stabilizer masterbatch for the above applications. These masterbatches provide the clients with more stabilization options that deliver outstanding results and cost efficiency.

We manufacture nucleating agent master batches, which are supplied under the brand name 'NUKON'. These NUKON master batches are formulated from carefully selected organic compounds like:

• Salts of mono or polycarboxylic acids
  
• Long chain ester ionomer.
  

Most of the nucleating agents added to the polymers control the crystal structure and produce a high degree of crystallizing with fine grain spherulite structure. It not just increases optical properties like transparency, translucency but in addition improves physico-mechanical properties. Nucleation effects are used to enhance the processing and end product characteristics viz, dimensional stability, post mold shrinkage etc. These 'NUKON' master batches are available in concentrations of 10-20% active ingredients.

We offer slip / anti-block masterbatches, that are marketed under the brand name 'SLABKON'. Our slip masterbatches and anti-block masterbatches for LDPE / LLD / PP Films are in sync with the specifications of ISO.

Slip master batches for LDPE / LLDPE / PP Films :

These slip masterbatches are manufactured using additive from fatty acid amide group. We provide 2 types of Masterbatches for this application based on the migration characteristics.

Slip Masterbatches are manufactured on fast migration characteristic additives to get immediate lowering of co-efficient of friction is required. Apart from this, masterbatches are also available on slow migration characteristics of the additive. The concentration of these slip masterbatches depends upon polymer type and degree of COF required.

Antiblock masterbatches for LDPE / LLD / PP Films

The blocking tendency of film surfaces can be eliminated through adding an anti-blocking agent masterbatch during the processing of these films. KONSPEC offers antiblock masterbatches for LDPE / LLD / PP Films, that are based on the selica or finely grounded mineral fillers and fatty acid amide additives are the combination of these additives.

We also offer the masterbatches, which have

• Balanced slip
  

Anti-blocking characteristics for certain specific applications.
