Talc in Plastics - تالک در پلاستیک ها

    33em; ">® talcs are best suited for general purpose blown films.33em; ">® family of products should be used. In addition to size, talc particle shape and particle aspect ratio can be used to further optimize these properties. This and slightly coarser products act as nucleation centers, increasing the temperature at which the polymer crystallizes and solidifies, thereby reducing cycle time and increasing productivity. Talc filled olefins also exhibit ductile fracture while the base resin fractures tend to be brittle.specialtyminerals. Talc-filled polypropylene works well in appliance applications requiring load-bearing properties at ambient and elevated temperatures.com

    . These high brightness products provide increased stiffness, i.  

Thermoplastic elastomers, whether they be homopolymer, copolymer or TPO resin systems, benefit from the addition of the appropriately sized, high aspect ratio talc. During polymer processing, talc, as the softest mineral, minimizes equipment wear. Talc-filled polypropylene automotive parts, whether they are interior, exterior or under the hood applications, have the required stiffness, strength and other mechanical properties.

For nucleation, use an ultrafine ground talc such as UltraTalcSpecialty Minerals Plant Locations and Profiles

    Specialty Minerals Talcs in Plastics
    A variety of talcs are manufactured by Specialty Minerals to suit the formulator’s need to optimize the properties of a particular polymer system for a particular application. In addition to being a cost-effective filler, talc can effectively provide antiblocking, reinforcement, and improved barrier properties.

      Talc in Plastics

    Talc is a highly functional additive that enhances key properties of numerous resins.  ABT® AG talc series offers a cost-effective alternative.

    In polyethylene film applications, talc is an effective, low abrasion antiblock.specialtyminerals. Vernon, Indiana, MicroTuff® talc products are ideal for the high performance automotive TPOs for interior and exterior applications. Polyester gel coat barrier properties are improved with the addition of fine ground, platy talc. FlexTalc 610, an ultrafine 1 micron talc, provides the best performance. When the highest clarity is required, the Optibloc

    Specialty Minerals was the developer of talc-based antiblock additives for polyethylene films.

    As an example, talc with an aspect ratio of 10 to 1 when melt compounded with a homopolymer will provide a 250 percent increase in flexural modulus.com/fileadmin/images/smi/SMI_PlasticWrappedFood.33em; ">® 9100 talc series are recommended.


    Uses For Talc In Plastics
    Plastics exhibit increased stiffness, reduced mold shrinkage, improved heat stability and lower material costs when filled with the appropriately sized talc.33em; ">® 609 talc.com/fileadmin/images/smi/SMI_Dashboard.e. Impact strength can be maintained when the particle size is carefully controlled to a 1 to 2 micron, ultrafine median particle size while maintaining a minimum top size.33em; ">® and Polybloc گزارش پست ]
