Resin Compatibility with Color Effects

RTP Company’s colorists are continually developing new and exciting color effects that can make applications distinctive and appealing to consumers. Certain technologies, such as those that create glimmer effects, are only effective in transparent or translucent resin systems. This chart provides a quick overview of the opacity of common resin systems to determine their compatibility with some of RTP Company’s color effect technologies.

IDPs and ICPs Help Keep Sparks from Flying

It is a common phenomenon that sparks due to static electricity buildup can be generated from contacting highly conductive metals like door knobs and metal desks. Occasionally, ESD composites, which contain highly conductive particles such as carbon or metal fibers, can exhibit this same sparking tendency.

A safer solution, especially important in hazardous environments, is to use materials that can control the speed of discharge while still providing a safe, rapid decay of accumulated static. The fine network and inherent conductivity of IDPs (Intrinsically Dissipative Polymers) and ICPs (Inherently Conductive Polymers) result in compounds that are typically able to rapidly decay a static charge without generating a hazardous spark. These compounds have also shown excellent performance when tested under various explosion-proof standards.

New Uses for High Gravity Compounds

RTP Company has developed many density-modified compounds with specific gravities up to 11.0 g/cm3. Typically these compounds are used as a replacement for lead or in other applications where duplicating the heft of metal is desired. High gravity compounds have also been successfully used in sporting goods and recreational applications such as: bats, clubs, racquets, and footwear. High gravity materials improve performance in these applications by shifting the center of gravity to increase energy at the point of contact.
