Antioxidant helps to reduce the degradation of appearance and physical properties of Polymers. Degradation is caused as a result of the collective actions of shear, temperature, and oxygen during processing and is known to lead to a number of undesirable effects, such as discoloration, melt viscosity changes, high processability, and poor polymer processing, especially during multiple heat histories.
Flame retardant masterbatch added with multiple types of flammable thermoplastics to reduce fire ignitions, decrease the extent of spreading flames, suppress the formation of smoke, and prevent the melting of polymers.
Desiccant masterbatches can counter problems which develop during the processing of plastics due to the presence of moisture. Moisture can be present in raw materials such as hygroscopic polymers, fillers and pigments or recycle polymer.
Anti Rodent Masterbatches are made with non toxic and non hazardous additives is an extremely pungent tasting material. It acts by emitting an odor which is unpleasant to rodents. It also contains special chemicals which rodents find extremely unpleasant to nibble or chew thus effectively keeping rodents at bay.
Anti microbial masterbatch can help protect plastics but they can also bring an interesting added value by impacting on the comfort and health image desired by end-users. Anti microbial is introduced in the material to kill or suppress the growth of algae, bacteria and/or fungi to keep product safe.
Antifog masterbatch prevent condensation of water vapor on the surface of clear film. These droplets cause poor film transparency, low attractiveness and spoilage of packaged food.
Foaming agents are the additives which evolve gas through chemical reactions or through thermal decomposition. This gas creates cell structure in the polymer matrix.
Crystallinity of semi-crystalline polymers is responsible for many of the characteristics, such as dimensional stability, clarity, and toughness.
For a defined part and process, the crystallinity is controlled by the polymer structure, the formulation, and the processing conditions that result in a specific balance of heat build-up and cooling. Consequently, crystallinity is often heterogeneous, the heat history being different for the skin and the core of the parts or goods.
Nucleating agents and clarifiers speed up and tune the crystallization allowing to adjust the end properties of semi-crystalline polymers to the functional requirements.
In polypropylene formulations, adding nucleating agents (also called nucleators) result in improved performance & processing properties, such as:
