Speciality and Fine Chemicals

Adhesive formulations often involve filled or viscous suspensions that require reliable clarification and filtration. DrM’s enclosed filtration systems are ideal for processing resins, binders, and additives, removing unwanted solids while maintaining product quality. Our filters support cake washing and heel volume recovery to maximize yield and reduce waste. With a fully automated cycle and compatibility with sticky or thixotropic materials, FUNDABAC® and CONTIBAC® units are well suited for adhesive manufacturing and recovery processes.​

Catalyst production often involves high-value solids, sensitive materials, and demanding process conditions. DrM filters are used to recover solid catalysts, remove fines from suspensions, and separate mother liquors during synthesis. Our systems can handle both wet and dry cake discharge, support full automation, and are built with corrosion-resistant materials to withstand aggressive chemistries. Whether for precious metal recovery or fine powder purification, DrM offers a closed, safe, and efficient solution for catalyst manufacturing.​

In the coatings industry, achieving uniform dispersion and clarity is essential for performance and appearance. DrM filtration systems help remove undispersed pigments, agglomerates, and gel particles from resins, varnishes, and emulsions. The ability to operate with filter aids enhances performance with viscous or high-solids formulations. Our filters provide consistent separation, high throughput, and can be adapted for solvent- or water-based systems with suitable materials of construction.​

Cosmetic manufacturing demands high clarity, smooth textures, and compliance with hygiene standards. DrM filters are used to clarify creams, lotions, gels, and emulsions by removing particulate matter or process residues. The fully enclosed design and optional CIP/SIP capabilities support GMP compliance and product integrity. We offer solutions for batch and continuous processes, helping ensure consistent product quality in skincare, personal care, and beauty formulations.​

Filtration of dyes and pigments involves separating fine particles from high-solids or highly colored slurries. DrM’s FUNDABAC® systems are well suited for capturing and recovering valuable pigments while delivering high filtrate clarity. Cake washing and drying steps help recover more product and minimize waste, especially with organic or synthetic pigment suspensions. Filters can be tailored with corrosion-resistant materials to handle aggressive solvents or acidic pH conditions common in dye production.​

The production of flavors and fragrances often involves natural extracts, essential oils, or fine suspensions that require careful clarification. DrM filtration systems help remove waxes, fibers, and insoluble residues while preserving the aroma and potency of high-value ingredients. Our fully enclosed, automated filters minimize product exposure and cross-contamination, supporting both batch and continuous operations. Materials of construction can be selected for compatibility with alcohols, solvents, and other reactive compounds commonly used in fragrance and flavor formulations.​

In oil additive production, catalysts and bleaching agents like bleaching earth are commonly used and must be thoroughly removed from the product stream. DrM’s FUNDABAC® filters are well suited for this application thanks to their fully enclosed and automated design, ensuring safe handling of high-temperature and flammable products. Our systems support efficient removal of fine solids, product recovery through cake washing, and dry discharge to minimize waste and reduce handling costs. With no rotating parts and high-temperature-resistant materials, DrM filters deliver long-term reliability with minimal maintenance in demanding additive processes.​

Plasticizer production, particularly phthalate esters like DOP and DIDP, involves complex reaction and purification steps that generate viscous, sticky by-products requiring effective solid-liquid separation. DrM FUNDABAC® filters are used in both crude and clean ester filtration stages to remove residual alkaline salts, pigments, and active carbon after bleaching. Compared to traditional vertical leaf filters, the FUNDABAC® system significantly reduces filter aid consumption and improves discharge efficiency. Systems can be configured for batch or continuous operation with dry cake discharge and support high filtration rates even with challenging viscosities and solids content.​

Polymer manufacturing often involves catalyst-driven reactions and multi-step processing, which produce solid by-products, fines, or gel particles that must be removed to ensure product consistency and downstream compatibility. DrM’s FUNDABAC® filters are commonly used for catalyst recovery, intermediate clarification, and final product polishing. Their enclosed design and automated discharge options make them ideal for viscous or hazardous media. Systems can be tailored for either wet or dry cake discharge, offering flexibility depending on polymer type and recovery goals. This results in improved product purity, reduced solvent losses, and higher overall yield.​

The production of rubber vulcanizing agents, including sulfur donors and accelerators, requires reliable filtration to separate solids from highly reactive or corrosive intermediates. DrM systems provide enclosed, automated filtration that supports safe handling of challenging materials while maintaining high throughput. Our filters are constructed from resistant alloys or lined materials to tolerate aggressive chemistries involved in the synthesis. Automated back-flushing and cake drying enable clean solids removal and reduce operator exposure. These features make DrM filters ideal for continuous or batch vulcanizer production with a strong focus on safety and process uptime.​

In special resin production, filtration is required at several stages, from catalyst removal to pre-polymer clarification and post-reaction polishing. These resins often have tight purity requirements, making reliable solid-liquid separation essential. DrM filters offer a closed, automated system capable of handling viscous fluids, solvent-based mixtures, and temperature-sensitive reactions. With dry cake discharge and optional cake washing, operators can recover valuable product while reducing waste. Our systems are used across epoxy, acrylic, phenolic, and polyurethane resin applications, supporting both standard and custom-built plant configurations.​

Synthetic fiber production involves polymerization and spinning of materials such as nylon, polyester, or acrylics, where gel particles and fines must be removed to prevent nozzle clogging and ensure uniform fiber quality. DrM filtration systems are used to clarify polymer solutions, remove catalyst residues, or treat additives before fiber extrusion. Operating under high pressure and temperature, the systems support continuous or batch operation with low downtime and minimal hold-up volume. Their modular design allows integration into both pilot and industrial-scale fiber production lines, delivering high clarity, safety, and long-term process reliability.​
