Rheology / Viscosity Modifiers for Plastic Compounds

CHARGUARD™ 2000 by Elementis is an organically modified mineral thickener. It is suitable for suitable for compounding in combination with fire retardants in low to intermediate polarity thermoplastic resin systems. It does not contain intentionally added per- and polyfluoroalkyl substances (PFAS).

• It enhances the effectiveness of non-halogenated and halogenated fire retardants by delaying the combustion process and stopping the spread of molten flame drip.
• It creates char layer oxygen barrier which is non-flammable and reduces the availability of combustible gases generated during thermal decomposition.
• It reduces the amount of smoke produced in a fire, which is a significant factor in improving fire safety and survivability.
• It is suitable for halogen-free flame retardant thermoplastic compounds such as ethylene-vinyl acetate co-polymer (EVA), low density polyethylene (LDPE), high impact styrene (HIPS), polypropylene (PP), polyamide (nylon 6) and polylactic acid (PLA).
• Recommended dosage level is 3.5%-5% as supplied based on total formulation weight.
• CHARGUARD™ 2000 has a shelf life of 4 years.

REGRATEX MB-D by Greenchemicals is an intrinsic viscosity enhancer, chain extender, regrader and re-polymerizating agent, through the extrusion process. It also acts as a processing aid.

• It increases the viscosity of polymers, improves the mechanical properties and increases the pressure on the extruder die when compounded into polyesters.
• It is suitable for PET transparent such as bottles, films, sheets and straps.
• Recommended dosage level of REGRATEX MB-D is 0.1 to 1%.

SILMAPROCESS AL2660 by Silma is a highly concentrated masterbatch of super-high molecular weight functionalized polysiloxane, finely and synergistically dispersed on LLDPE carrier.

• It is used in halogen-free compounds as a processing aid, improving viscosity and homogeneity.
• It acts as a flame-retardant synergist (L.O.I.) and smoke suppressant, while also eliminating surface defects and die drool.
• It works as a slipping agent, external lubricant, and releasing agent during cable extrusion.
• It improves mechanical properties and surface quality of the finished goods.
• It reduces melt viscosity during compounding, enhancing throughput, stability, compound homogeneity.
• SILMAPROCESS AL2660 reduces THR (Total Heat Release) and PHRR (Peak Heat Release Rate) in halogen-free compounds and serves as a scratch and abrasion resistance enhancer in polyolefin and rubber compounds.
• The recommended dosage for the processing aid is 0.5-1%, while for extrusion or injection molding processes is 0.5-5%.
• It has a shelf life of one year.

VM-r105 by Milliken is a solid concentrate for viscosity modification of polypropylene (PP). It is designed to increase the melt flow rate in a very cost-effective manner.

• It shortens the material’s average molecule chain length, resulting in an easier, more consistent flow.
• It offers improved processability, and lowers molding processing temperatures, which can significantly reduce cycle times and increase productivity.
• It allows for precise dosing, easy & dust-free handling, and can be stored under standard warehouse conditions.
• VM-r105 is suitable for use in resin production, compounding, injection molding and extrusion.
• The low volatiles content originating from peroxide decomposition products, forms no acetone and no tert-butanol.
• It has a shelf life of 12 months.
