Our antistatic polymer concentrates are formulated to be used at a let-down ratio of 10:1 (polymer:concentrate). Using concentrates at higher let-down ratios leads to poor mixing and slower decay times. It can also lead to "hot spots".
Use of Dyneon antistatic plastic concentratrates at a 10:1 let-down ratio does not alter the physical properties of the host polymer other than improving its antistatic performance. In addition, transparent polymers are unaffected in optical properties (i.e. they remain transparent) while reaching surface resistivities of 109 to 1011 with Dyneon antistatic concentrates.
For more thorough discussion of antistatic polymers and technology please visit our Conductive Polymers page. Dyneon Polymers makes an extensive series of concentrates which can be used with a wide variety of polymers to impart antistatic features to fabricated products.
Contact Us or call (859) 334-4500 to speak with a Dyneon representative regarding your specific needs for an antistatic plastic or concentrate. If possible please specify polymer type and decay characteristics desired or tell us what general properties and performance are needed. With that information we can make recommendations to meet your needs.
