Technical Polymers Material

Volumetric and Gravimetric Dosing Systems are available for On-Machine Injection and Extrusion Processes of Plastics & Chemicals .
Different blender models are available which have been designed especially for feeding either blended bulk materials  or individual additives  or  polymers directly into injection molding machines or plastics extrusion applications.  Depending on degree of desired automation ,four or six feeders can easily grouped around an extruder inlet .Alternately Single station  feeders are also available.
A) Gravimetric Dosage Systems are available in different capacities.
The gravimetric dosing systems are constituted by equipments for dosing plastic materials  e.g color pellets, modifiers or free flowing additives by means of electronic balances applied to dosage units; the morphology of these systems, in general, can be different depending on the application and the type of gravimetric dosing (sum in weight [batch], or loss in weight).
The technologies used  for reading the processed material from the gravimetric dosing unit, are of two types:
- loss in weight, where each material to be dosed is individually and continuously weighed.- Sum in weight, where the various materials to be dosed are weighed into a unique balance in a sequentially way .
B) Volumetric Dosage  Systems  may be set for batch or continuous processes  and are available in different capacities.They are equipment for dosing plastic materials realized by means of dosage units with rotating screw; the morphology of these systems, in general, can be different depending on the application and the type of dosing technology (speed variation or time variation).
The technology used for volumetric dosing units is of two types:
speed variation technology, where each component has available a dosage unit whose flow is determined by the speed of rotation imparted to the metering screw.- Time variation technology, where each dosage unit is operated at a fixed speed by the control system for an interval of time necessary to the set dosage.

C) Small,Medium & Large Soundproof Granulators: A range of small and medium sized granulators with high performance are avialable.They are employed for a variety of  small and medium-duty applications:from light to medium injection mouldingscraps, blow moulding and extrusion  lines of pipes and profiles. Granulators designed for heavy duty  and high capacity granulation due  to their performance efficiency and  versatility are particularly suitable  to recover heavy extrusion purging, injection moulding scraps, as well as  scraps from plates and film sheets.

We also coordinate and supply turnkey solutions for centralized vacuum conveying system which provides a reliable and clean transport of plastic material in granules.The vacuum pump assures high performance and does not require maintenance.An automatic safety filter protects the blower and the environment and allows central dust collection.The hopper loader cylinders are equipped with an automatic filter cleaning system after each loading cycle, an air detection valve and a sensor indicating maximum level of material.The electrical control panel is based on a PLC, which controls the loading processes and the no-load alarms of the hopper loaders.

Customised engineered solutions for Bulk Material Handling Equipment & special feeding solutions for very low feed rates, very high feed rates, and for multi-feeder blending are also available and you may directly contact us at info@technicalpolymers.in for further information or feeding solutions for your applications.

ANTIOXIDANTS
Antioxidants are used to retard the reaction of organic materials such as synthetic polymers, with atmospheric oxygen. Such reaction can cause degradation of the mechanical, aesthetic, and electrical properties of polymers; loss of flavor and development of rancidity in foods; and an increase in the viscosity, etc. Though required in small amounts at any one time, they are absolutely necessary, as without antioxidants, many products would not last very long, and many plastics could not even be manufactured without their protective attributes. Acting as stabilizers, they are also useful in facilitating the production of fuel and lubricants. 
We  supply antioxidants from  IONOL ,Raschig in North India belonging to the group of non-staining sterically hindered phenols which shows an excellent stability at high temperature hence it does not show discolouration & is non staining. Phenolic antioxidants are used for stabilizing elastomers based on natural and synthetic latices and rubbers, as well as ABS, PA, polyolefins, hot melts and lubricants and has BfR and FDA approval.IONOL  has also been recommended for use under high temperature hot melt stabilizers and lubricants.

TITANIUM DIOXIDE- RUTILE & ANATASE
Titanium dioxide (TiO2 ) is the most widely used white pigment because of its brightness and very high refractive index, in which it is surpassed only by a few other materials.  The most important application areas are paints and varnishes as well as paper and plastics, which account for about 80% of the world's titanium dioxide consumption. Other pigment applications such as printing inks, fibers, rubber, cosmetic products and foodstuffs account for another 8%. The rest is used in other applications, for instance the production of technical pure titanium, glass and glass ceramics, electrical ceramics, catalysts, electric conductors and chemical intermediates.
TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets) as well as most toothpastes. In paint, it is often referred to offhandedly as "the perfect white", "the whitest white", or other similar terms. Opacity is improved by optimal sizing of the titanium dioxide particles. Some grades of titanium based pigments as used in sparkly paints, plastics, finishes and pearlescent cosmetics are man-made pigments whose particles have two or more layers of various oxides .
Rutile is the most common natural form of TiO2. Another polymorph of TiO2 widely used is Anatase.Rutile has among the highest refractive indices at visible wavelengths of any known crystal, and also exhibits a particularly large birefringence and highdispersion.

Multipurpose Rutile titanium dioxide for both interior & exterior coatings is available with excellent balance of chalk resistance,hiding,gloss,tint,physical property retention and outstanding dispersion performance at economical prices for a broad range of exterior & interior applications in paints & coatings which require highest level of durability.The surface treatment with special grades supplied also provide high level of UV radaiation protection as strongly absorb radiation below 380nm.An additional alumina treatment provides dry bulk conveying & better dispersability.

Grades recommended  for interior decorative coatings, road marking paint, window profiles, masterbatch, rubber, paper , Polymers, ceramics etc. are available. For further information and technical specifications please contact us atinfo@technicalpolymers.in

Masterbatches : Technical Polymers Material offers Master batch to Polymer Processors as a convenient ,economical and uncomplicated  method of adding desired colour and/or performance enhancing additives to natural or base polymers on their own plant. This technique of  getting desired colour or performance is adopted in the polymer industry as it gives a unique combination of cost savings and technical benefits including reduced inventory of compounds , reduction in cleaning costs & cross contaminations, dust free environment, reduction of purging costs,optimum dispersion and  reliable colour and performance properties in the final product.
Master-batch is a solid concentrate of colour and/or performance enhancing additives such as anti-static, UV stabiliser, metal deactivator, that is added to a base polymer to impart these attributes. It is supplied in granular form, either as pellets similar in size to most polymers or as miniature pellets, known as micro granules.

Two main types of Master batches are offered - polymer specific and universal. Polymer specific master batch is produced using the same base polymer group as the type of polymer being used by the processor. Universal master batch employs a carrier system that is capable of carrying the high quantities of additives necessary to deliver the end use properties required as well as affording the essential compatibility required across a broad range of polymers. Universal master batches are normally readily available from stock, in small quantities and are cost effective if used correctly.  They are not recommended for use at high dosage levels as the appearance or physical properties of the final product may be adversely affected. End  application will always influence the type of master batch chosen. Toys and food packaging for example have to be produced from materials made with 'controlled' ingredients and engineering products will demand reliable high performance properties

Master batch can be introduced to the processors' base polymer  or compound on the production line in a number of ways, the most successful methods being volumetric or gravimetric dosing. In both techniques, the master batch is added directly into the polymer stream immediately before processing. Volumetric dosing has the advantage of relatively low capital investment but requires calibrating every time the batch or colour is changed (depending on the bulk density of the material). Gravimetric dosing is extremely accurate, but plant is expensive.Dosages vary based on colour; wall thickness and opacity requirements .Master batch performance during processing is influenced by blending process and dosage level especially for transparent products.

Masterbatches are used during Injection moulding, blow moulding, profile extrusion, sheet extrusion, film extrusion, cast film, fibres and calendered sheet processes.

We offer a broad selection of standard or specialised/customised traded masterbatch compounds based on:
• Thermoplastic Engineering Resins Polyamides, Polyesters, Polycarbonates, PP and ABS

Engineering Plastics are a group of polymeric materials that have better mechanical and/or thermal properties than the more widely used commodity plastics .Being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low-volume applications (such as mechanical parts), rather than for bulk and high-volume ends (like containers and packaging).Engineering plastics have replaced traditional engineering materials such as wood or metal in many applications. Besides equalling or surpassing them in weight/strength and other properties, engineering plastics are much easier to manufacture, especially in complicated shapes.
