Esstech, Inc. offers a variety of ground glasses with a wide range of particle sizes. These glasses are ground to meet your filler requirements. We offer precise X-Ray opacity, a range of options for composition, and a refractive index for esthetically pleasing composites.
Our EssSil™ brand of fine particle-sized silanated dental glass provides consistent barium content and silane loading to deliver the required refractive index for optimum results. It is designed to enhance mechanical retention of the glass in the polymer matrix and is available in a variety of size categories to meet the demands of the composite manufacturer.
Manufacturing quality adhesive components requires raw materials of uncompromising purity. Their multiple applications place a considerable burden on their performance. The challenge is further heightened by the difficulty in synthesizing these molecules. They are capable of bridging the gap between hydrophilic and hydrophobic substrates. Only the most experienced chemists can achieve these characteristics. This limits the source for such raw materials to one company, Esstech, Inc.
The successful production of quality composites, coatings and adhesives requires monomers featuring low color and acid in addition to the appropriate inhibitor, viscosity and refractive index values. A low color raw material will enhance the appearance of the final product. The low acid value reduces the amount of inhibitor required while extending the shelf life of your product. A consistent viscosity allows you to reproduce the same product time after time.
The challenges involved in formulating products can be overcome by the inclusion of specifically designed monomers. Monomers used in these applications can act as diluents or actively participate in forming a polymer matrix. To modify the polymer matrix, you must know what monomers can be added in what quantities to achieve the desired properties. The process of identifying the correct molecule with the correct purity and inhibitor level is difficult. Allow Esstech, Inc. to simplify the process.
Formulating high quality products depend on the characteristics of your raw materials like color, acid, inhibitor, viscosity and refractive index. Consistent low color positively contributes to the appearance of the final product. The low acid value helps to stabilize the product and ensures an extended shelf life. Subsequently, the low residual acid content also allows for lower levels of inhibitor without compromising stability. Consistent viscosity delivers the desired physical characteristics while achieving the required refractive index that matches your final product. Esstech, Inc. is a reliable source that can produce materials with such strict specifications.
Esstech, Inc.'s high-purity monomers are ideal for optical and medical applications, providing manufacturers with consistent low color, appropriate inhibitor packages, consistent low acid and enhanced stability. These requirements must continually be met without deviation in order to efficiently manufacture quality materials.
Esstech, Inc. produces numerous acrylic polymers. Our products and processes are flexible enough to match your needs without sacrificing quality. Our methacrylate polymers are tested to match strict molecular weight specifications (mw, mn and mz). Our acid containing polymers are available in a variety of acid loadings and molecular weights. Our goal is provide you with the best material to match your mechanical needs.
Purity is important in the production of our specialty products. These materials fulfill the difficult role of initiating the cure of the polymer matrix. Synthesizing these molecules requires a level of sophistication and expertise that limits the source to Esstech, Inc.
