Dispersing Agents for Plastic Compounds

AClyn® 295A distributed by DKSH is a pigment dispersing agent for masterbatch in polar resin systems due to enhanced compatability with the resin carrier. It is zinc ionomer of EAA (ethylene acrylic acid) copolymer neutralized to 98%.

• It provides corrosion resistance, filler dispersion and increased tack.
• It is used in engineered plastics.
• AClyn® 295A is available in Australia, New Zealand, China, Japan and Philippines.

VALPOL GP-4350 by Greenchemicals acts as a processing-aid, dispersing agent and surface slippery promoter. It is a general-purpose additive designed for technopolymers, including high-temperature processing polymers such as polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polysulfones, and polyether ether ketone (PEEK).

• It reduces the viscosity during melting while maintaining intrinsic viscosity, leading to lower processing temperatures (by 35-40°C), which extends the thermal lifespan of polymers, particularly those sensitive to heat like POM and wood-plastic composites.
• It avoids the extrusion "empties", problem that often occurs specially extruding polymers with different or "disordered" viscosities (in the fibers extrusion the phenomenon induces breakages).
• It enhances extrusion efficiency, preventing extrusion voids and improving polymer intermeshing in blends like acrylonitrile butadiene styrene (ABS)/polycarbonate (PC), polycarbonate (PC)/polybutylene terephthalate (PBT), and polystyrene (PS)/polyethylene (PE).
• VALPOL GP-4350 also facilitates better pigment, filler, and glass fiber dispersion, improves mold release, reduces cycle times, and minimizes surface friction and wear on extruder components, particularly in glass fiber-reinforced polymers.
• Recommended dosage level is 0.25-1%.
• Higher dosage of up to 1.5-2.0% can be used without affecting the printability, weldability, or sealability of the polymers.

RHEOSOLVE™ D 5S distributed by DKSH is a dispersing agent for the household and industrial industry. It prevents soil and mineral redeposition and presents good chlorine compatibility. It is a ready to use polyacrylic acid, sodium neutralized in aqueous solution.

• It has a shelf life of 1 year.
• RHEOSOLVE™ D 5S is available in Canada.

A-C® 6A distributed by DKSH is low density polyethylene homopolymer. Acts as a dispersing agent in color masterbatch applications. It is also used as a gellant for hydrocarbon oils, a paraffin crystal nucleator in wax blends such as candles, and a viscosity diluent in HMAs.

• Used in cable flooding compounds, along with polybutene.
• A-C® 6A is available in Australia, New Zealand, China, Japan, Philippines and Malaysia.

HYDRODIS® RB 4385 distributed by DKSH is an anionic dispersing agent. It is a polynaphthalene sulphonates salts are stabilizers for latex(from natural or synthetic rubber) and act as dispersants of pigments and fillers used in the curing processes.

• It permits the addition of electrolytes during polymerization process (essential to control the viscosity) without subsequent instability during the reaction.
• HYDRODIS® RB 4385 is hygroscopic and has a shelf life of 24 months.
• It is available in Asia Pacific.

A-C® 400A distributed by DKSH acts as a dispersing agent for color masterbatch in stryenic resins and process aid for EVA-based wire and cable compounds. It is an ethylene vinyl acetate (EVA) with a VA content of 13%.

• It provides the dual function of reducing application viscosity at melt as it can be added as a diluent.
• It is used in candles to provide paraffin crystal nucleation, adhesion to glass and fragrance retention.
• It is available in Australia, China, Japan, Malaysia, New Zealand and Philippines.

A-C® 540A distributed by DKSH is a dispersing agent for color masterbatch in engineering resins. Excellent external lubricant for polyamide compounds. It is an ethylene acrylic acid (EAA) copolymer with an acrylic acid (AA) content of 5%. A-C® 540A is available in Australia, New Zealand, China, Japan and Philippines.

A-C® 617 distributed by DKSH acts as a dispersing agent in color masterbatch applications and external lubricant for PVC applications. It is a low-density polyethylene (LDPE) homopolymer in prill form. It is used as a gellant for hydrocarbon oils, a paraffin crystal nucleator in wax blends such as candles. A-C® 617 is available in Australia, New Zealand, China, Japan and Philippines. It is indirect FDA approved.

FilmLink® 520 by Imerys is a treated ground calcium carbonate promotes breathability in plastic films for sanitation products. It also acts as a dispersing and thixotropic agent in breathable polyolefins. It is recommended for applications such as diapers, feminine hygiene products or roofing films and personal protective equipment (PPE). It improves mechanical, rheological, optical & dispersion properties and reduced waste. FilmLink® 520 provides high brightness, high opacity, good color, controlled surface treatment to reduce volatile effect and defined particle size distribution for good properties.

WARADUR® OP distributed by DKSH is an ester wax consisting of esters of montanic acids with multihydroxyl alcohols. It acts as a nucleating-, release agent, flow improver, dispersing agent for color masterbatches and filled plastics (talc, glass fiber), gloss booster, surface improver.

• It is made from a fossil biological source.
• The corresponding esters in WARADUR® OP exhibit chain length in the range of C58-C66 and provide this wax with a low volatility, good thermostability and low migration rates.
• It is compatible with thermoplastics such as PA, PBT, TPE, PC, PVC, styrenics, thermosets such as epoxy resins, phenolic resins and polyurethane.
• The maximum shelf life is 5 years.
• It is available in Malaysia.
