Beta Nucleating agent for polypropylene is used to introduce the beta type crystals of iPP in injection molded, extruded, blow molded and therformed products. Isotactic homo-polypropylene (PP) is a semicrystalline polymer of great commercial importance. In its solid state, microscopic crystalline and amorphous domains intermingle. The crystalline unit cell is usually monoclinic. This crystal configuration is called the (alpha) form. There is also a ?? (beta) form with hexagonal unit cells, which is usually present in small quantities, if at all unless special processing conditions or special nucleating agents described in this article are used. The physical properties of the ?? and ?? forms differ, and this difference can be used to advantage in certain applications, as will be explained. When comparing crystalline PP to predominantly crystalline PP, the latter is found to show the following differences: Lower Youngs modulus. Lower yield stress. Higher elongation at yield. Higher elongation at break. Higher impact strength. While these properties are not necessarily desirable in a finished product, they can greatly improve the draw (stretch) ability of PP sheet at temperatures where it would normally draw very unevenly or break. Other key findings pertaining to PP with a finite ?? crystalline content: When subjected to tensile stress at temperatures below the melting point of the phase, crystallites convert to The conversion is accompanied by cavitation i.e. the formation of numerous microscopic voids. When maintained at temperatures above 120C, crystallites convert to The conversion accelerates as temperature increases. Our beta Nucleating agent Masterbatch gives excellent improvement in toughness, impact strength and HDT. The impact strength of iPP may be improve upto 250% by 1-3% use of beta Nucleating agent. HDT may go above boiling water temperature.

As polypropylene is a semi-crystalline polymer, it is naturally translucent or opaque. The addition of nucleating agent called macroclarifier, It can make PP highly transparent. SPECIFICATION: State : Ultrafine white powder Color : White Odor : Odurless Melting point oC : 240-250 Moisture content : 1.0 Macroclarifier is a sorbitol based nucleating agent. It has following benefit Improved Properties Macroclarifier offers improved physical properties. particularly higher stiffness and heat distortion temperature. Cost Efficiency The cost efficiency of PP, combined with its low density, makes it an attractive alternative to other resins.The cost efficiency of PP, combined with its low density, makes it an attractive alternative to other resins. Versatility Macroclarifier offers an excellent combination of properties - toughness, flexibility, rigidity, moisture barrier, chemical resistance, heat resistance, and suitability for food contact. Clearest PP Possible: The highest clarity, gloss and surface smoothness available. Ideal for Food Contact Applications : Macroclarifier does not affect the taste of contained foods or liquids. Increased Productivity: Macroclarifier gives higher throughput and productivity. It has many benefits compared to other materials - light weight, strength and cost effectiveness.

FeaturesNature : Non-Ionic Xanthation Agent Application : Useful in shredding and xanthation of in rayon staple fibre yarn and cellophnae manufacture. Reduces power and time requirement. In viscose rayon production this helps to keep spinerets clean and to extend coagulation time which allows for production of high tenacity rayon. CRISTOL is a well established brand in the manufacture and export of eco-friendly specialty performance chemicals for textile processing including surfactants, specialty chemicals and textile auxiliary chemicals. We have a wide range of pretreatment chemicals, dyeing agents, printing chemicals, finishing chemicals, spinning additives, xanthans & fibre / yarn production chemicals. Our products show application in Apparel such as casual wear, sportswear, denim, business, and work wear, Home Textiles such as towels, upholster and sheetings & Carpets and Technical Textiles such as medical garments and glass grid fabrics. Minimum Order Quantity : 2 Tons

Nucleating Agents:These additives MB are used for increasing the transparency in PP Moulded products.This Masterbatch contains third generation sorbitol derivative nucleating agents. Nucleating agent is a sorbitol based clarifying agent for polypropylene. Its nucleating activity results in the formation of spherulites that are less than 1 micron in size in comparison to non-nucleated products whose spherulites are larger than 20 microns. Spherulites are spherical semi crystalline regions inside non-branched linear polymer. The reduction in size of the spherulites brings increased transparency and rigidity of materials. Higher crystallization temperature results in shorter processing time, faster cycles and therefore higher output and productivity in short lower production cost. PP Containing nucleating agent is recommended to be processed at a melt temperature of 230-240 deg. Centigrade and with maximum back pressure in the injection moulding machine. Nucleating agents also improve the mechanical properties of PP like hardness, Tensile strength, elongation, elastic modulus and impact strength. It also shortens the cycle time in injection moulding process, since it reduces cooling time. Nucleating Agent Mastebatches offered by Sri Vasavi Pigments (P) Ltd. are
