VANFRE® L16 Processing Aids

VANFRE® L16 is very effective in improving the flow properties of rubber compounds because of the reduction of intermolecular friction and external friction on metal surfaces. VANFRE L16 has a stabilizing effect on the tendency of re-crystallization in Neoprene compounds. It has outstanding release during compounding and as a mold release after curing. For optimum release VANFRE L16 should be added during the final mixing stage. Recommended dosage: 1 to 5 phr.

VANFRE® L20 Processing Aids

VANFRE® L20 provides outstanding performance for most elastomers as a dispersing aid for commonly used fillers in rubber compounding. It also works very well as an internal release agent in injection and transfer molding, preventing sticking of compounds to rolls and rotors. VANFRE L20 does not adversely interfere with most curing systems. Due to its low dosage level there is hardly any or no effect on physical properties. Recommended dosage: 1 to 5 phr.

VANFRE® L22 Processing Aids

VANFRE® L22 improves the incorporation of fillers and metal release for most rubber compounds. Due to its low volatility, it can be used in high-temperature curing. VANFRE L22 provides good plasticizing properties which leads to reduction of injection pressure in the mold filling process and prevents scorch. It is also highly effective in polar compounds, e.g. NBR, HNBR, to improve flow and mold release. Recommended dosage: 1 to 5 phr.

VANFRE® L42 Processing Aids

VANFRE® L42 is very effective for most elastomeric compounds by providing excellent internal lubrication for improved mold flow and release. It is highly effective in EPDM compound. Recommended dosage: 2 to 5 phr.

VANFRE® L79 Processing Aids

VANFRE® L79 is an internal lubricant that provides good mold flow and release for ACM, FKM and HNBR compounds for high-temperature applications. Its excellent lubricating properties lead to a reduction of injection molding pressure in the molding process, helping to prevent scorch. Recommended dosage: 1 to 2 phr.

VANFRE® F44 Processing Aids

VANFRE® F44 is a processing additive for natural and synthetic rubbers. Due to its unique composition it provides excellent processing improvement for a wide range of elastomers like EPDM, NBR, NR and SBR. It improves filler dispersion, particularly for Silica and other mineral fillers. It also improves the cell structure of EVA foam products. VANFRE F44 provides outstanding performance in extruded compounds, but also works well for transfer and injection moulding. Recommended dosage: 1 to 5 phr.

VANFRE® F50 Processing Aids

VANFRE® F50 is a very effective for the physical peptization of NR, improving compound flow and carbon black dispersion. It quickly lowers compound viscosity, shortens mixing time, reduces energy consumption and improves processing efficiency. VANFRE F50 improves calendering and extrusion rates, while providing smooth surfaces. It also improves reversion resistance and tear strength. Recommended dosage: 1 to 5 phr.

VANFRE® F60 Processing Aids

VANFRE® F60 is improves mixing and processing as well as the incorporation of compounding ingredients. It is a very effective material for the physical peptisation of NR, improving compound flow and carbon black dispersion. VANFRE F60 is compatible with most elastomers and quickly: reduces compound viscosity, shortens mixing time, reduces energy consumption and improves processing efficiency. It also improves calendering and extrusion rates, while providing smoother surfaces. Reversion resistance and tear strength are also improved. Recommended Dosage: 1 to 5 phr.

VANFRE® F60T Processing Aids

VANFRE® F60T is improves mixing and processing as well as the incorporation of compounding ingredients. It is a very effective for the physical peptization of NR, improving compound flow ability and carbon black dispersion. VANFRE F60T is compatible with most elastomers and is quickly reduces compound viscosity, shortens mixing time, reduces energy consumption and improves processing efficiency. It improves calendering and extrusion rates, while providing smoother surfaces. It also improves reversion resistance and tear strength. Recommended dosage: 1 to 5 phr. .

VANFRE® B40 Processing Aids

VANFRE® B40 improves the homogeneity of polymer blends of different polarities or viscosities. It is rapidly absorbed by the polymer matrix as it wets the surfaces, which leads to fast incorporation of other compound ingredients. The reduction in compound viscosity will assists further processing, especially milling and calendering. VANFRE B40 is best added at the beginning of the mixing cycle in order to achieve the optimum wetting affect. Due to its dark color, VANFRE B40 is not recommended for light colored compounds. The recommended dosage is 4 to 15 phr. .

VANFRE® B60 Processing Aids

VANFRE® B60 improves the homogeneity of polymer blends of different polarities or viscosities. Rapid absorbed by polymer matrix as it wet the surfaces which lead to fast incorporation of other compound ingredients. The reductions of compound viscosity assists further processing, especially milling and calendering. VANFRE B60 is best added at the beginning of the mixing cycle to achieve the optimum wetting effect. It also increases green tack of compounds thru synergism with tackifying resins. Due to its light color it can be recommended for colored as well as black compounds. Recommended dosage: 2 to 5 phr .
