• It is easily dispersed in vinyl formulations assuring more consistent impact resistance and other physical properties.
• It can withstand severe processing conditions with minimal effect on heat stability and mechanical properties.
• Recommended for use in high quality technical films, edge-bands, CPVC pipes, fittings, furniture films and indoor profiles.
• It is also suitable for automotive applications, electrical and electronic components, household appliances and all PC & alloys parts where ease of processing, good low temperature impact and good balance of physical properties are important.
• Clearstrength® C-223 is used in formulations for food contact or drinking water conduction.
• Recommended dosage level is 2 to 20%.

DeltaMax® f500 by Milliken is an all-purpose modifier designed for use in injection molding applications. It offers improved impact properties while maintaining stiffness and increased melt flow to improve processing.

• It is suitable for polypropylene (PP) impact copolymers and recycled polypropylene (rPP) resins.
• DeltaMax® f500 offers additional benefit of being colorless.
• It can be added machine side at the feed throat or hopper between 0.5% - 1.5%.
• The shelf life of the product is 12 months when stored below 40°C.

Clearstrength® C-320 by Arkema is a methylmethacrylate-butadiene-styrene (MBS) core-shell impact modifier. Provides high optical properties and clarity. Imparts excellent impact strength and transparency. Recommended for high quality films, sheets and bottles. Clearstrength® C-320 is used in PVC formulations for food and pharmaceuticals.

Fine-Blend® CMG5805-L distributed by DKSH is an impact modifier for low temperature PA. It is a maleic anhydride grafted polymer. The base polymer is a polyolefin elastomer with high flexibility and it has white or light-yellow particle appearance.

• It improves impact property, low temperature resistance and reduce water absorption of nylon.
• It can be processed over a wide range of conditions.
• The typical processing temperature range is from 150°C to 280°C.
• It can develop a reliable bonding strength between PA/PP or PA/PE alloys.
• Recommended for use in super toughened, glass fiber reinforced nylon, flame retardant nylon and low temperature resistant nylon.
• It is also used for compatibilizer in non-halogen flame retardant polyolefin-based wire and cable compounds.
• Fine-Blend® CMG5805-L is available in Europe, North America and Asia Pacific.

DeltaMax® i300 by Milliken is a high-performance impact enhancer. It is designed for use in injection molding application of polypropylene impact copolymers and in recycled polypropylene resins. It maximizes impact performance while optimizing melt flow rate (MFR) for improved physical properties and processability of polypropylene. Recommended dosage level of DeltaMax® i300 is 0.5% to 1.0%. It has a shelf life of 12 months.

Blendex® 587S by DKSH is a polymer heat modifier that is suitable with PVC, CPVC, ABS and SAN. It is an alphamethlystyrene containing a high level of AMS. It is excellent choice for embossing retention during thermoforming.

• It increases the service temperature of products produced from PVC homopolymer and copolymers.
• It improves vicat & heat distortion temperature and also increases tensile & flexural properties.
• It can be used with a Blendex impact modifier to provide impact strength as well as high heat performance.
• It provides dimensional stability to PVC parts.
• Blendex® 587S is used in appliance and business machine housings, electrical and telecommunication devices.
• It is available in Europe.

DeltaMax® 5000a by Millikenis a performance modifier that helps to improve the melt flow rate (MFR) and impact strength for heterophasic polypropylene impact copolymers. It is used in conjunction with organic peroxide to enable controlled rheology modification. Recommended dosage level of DeltaMax® 5000a is 0.05% to 0.4% and peroxide is 0.01% to 0.1%. It has a shelf life of 12 months.

BRUGGOLEN® C540 by Brüggemann is an impact modifier for AP-NYLON® casting for the catalyst side. This viscous elastomer provides prolonged open time, toughness and a highly cost effective system for moldings. It works as a soft polymer segment in the polyamide 6. The dosage level of BRUGGOLEN® C540 is 1.5-25%. It has a shelf life of at least 24 months.

NYRIM® Additive 6 Plus by Brüggemann is a processing aid and impact modifier in the anionic polymerization of caprolactam along with the catalyst BRUGGOLEN® C10 and activator BRUGGOLEN® C20P (pellet form) or BRUGGOLEN® C235 (liquid form). It improves toughness and yield in machining semi-finished products. It can increase the low temperature impact strength of cast polyamide by the formation of a copolymeric structure. The anionic polymerization of caprolactam is inhibited by the smallest amounts of moisture therefore the process requires moisture-free raw materials and moisture proof conditions. It is recommended for large, low-tension semi-finished products such as bars, tubes and plates, to complex, often thick-walled molded parts that cannot be manufactured through injection molding or extrusion. NYRIM® Additive 6 Plus can also be used in rough and tough applications. The dosage level can vary from 2-20%. The shelf life of the product is at least 12 months under (dry, 25°C) conditions.
