    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. When mechanical demands are less, but brightness is still critical, the Mt.33em; ">® AG talc series offers a cost-effective alternative.e.

    In polyethylene film applications, talc is an effective, low abrasion antiblock.33em; ">® 609 talc. Talc also functions well as a nucleating agent during melt compounding. In addition to being a cost-effective filler, talc can effectively provide antiblocking, reinforcement, and improved barrier properties.  ABT® talcs are best suited for general purpose blown films.33em; ">® talc products are ideal for the high performance automotive TPOs for interior and exterior applications.com/fileadmin/images/smi/SMI_PlasticWrappedFood.   

    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.specialtyminerals.

      For nucleation, use an ultrafine ground talc such as UltraTalc® and Polybloc® family of products should be used. It also decreases mold shrinkage, and improves end product machining.33em; ">® 9100 talc series are recommended. 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., improve the flexural modulus, improve the heat deflection temperature and the tensile strength of the base polymer. 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.specialtyminerals.

Specialty Minerals was the developer of talc-based antiblock additives for polyethylene films. Talc-filled polypropylene works well in appliance applications requiring load-bearing properties at ambient and elevated temperatures. Polyester gel coat barrier properties are improved with the addition of fine ground, platy talc.


Talc in Plastics

Talc is a highly functional additive that enhances key properties of numerous resins. FlexTalc 610, an ultrafine 1 micron talc, provides the best performance.com/fileadmin/images/smi/SMI_Dashboard.  

Thermoplastic elastomers, whether they be homopolymer, copolymer or TPO resin systems, benefit from the addition of the appropriately sized, high aspect ratio talc. Talc filled olefins also exhibit ductile fracture while the base resin fractures tend to be brittle. 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.jpg" style="text-align: left; border-right-width: medium; border-right-style: none; border-right-color: initial; padding-right: 10px; border-top-width: medium; border-top-style: none; border-top-color: initial; padding-left: 10px; float: left; padding-bottom: 10px; border-left-width: medium; border-left-style: none; border-left-color: initial; width: 300px; padding-top: 10px; border-bottom-width: medium; border-bottom-style: none; border-bottom-color: initial; height: 110px; " />


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. Vernon, Indiana, MicroTuff این مطلب تا کنون 67 بار بازدید شده است.
