Rianox 245

CAS#: 36443-68-2  |  RIA245-CS

Rianlon Corp.

TDS

Rianox 245 is a high molecular weight hindered phenolic antioxidant that provides very low volatility and excellent resistance to extraction from polymer compounds. RIANOX 245 is effective in styrene polymers, particularly impact modified polystyrenes, ABS, MBS, SB and SBR-latices as well as in POM homo-and copolymers. It is also very useful for the stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC and other polymers. In addition to imparting thermostability to the finished polymer, RIANOX 245 is effective as chain stopper during PVC polymerization. RIANOX 245 can be used in combination with other additives such as costabilizers (e.g. thioesters, phosphites and phosphonites), light stabilizers, and other functional stabilizers. The effectiveness of the blends of RIANOX 245 with RIANOX 168 (RIANOX B-blends) is noteworthy.

Rianlon Corp.

TDS

Rianox 330 is a high molecular weight hindered phenolic antioxidant that provides very low volatility and excellent resistance to extraction from polymer compounds. RIANOX 330 exhibits superior performance over typical high molecular weight antioxidant in controlling degradation of polyolefin during processing. RIANOX 330 is resistant to water and solvent extraction and has been shown to decrease water carry over in water-quenched polypropylene film lines. Also, RIANOX 330 is not absorbed by fillers typically used in polyolefin.

Rianox 565

CAS#: 991-84-4

Rianlon Corp.

TDS

RIANOX 565 is a highly effective antioxidant for a variety of elastomers including polybutadiene (BR), polyisoprene (IR), emulsion styrene butadiene (SBR), nitrile rubber (NBR), carboxylated SBR Latex (XSBR), and styrenic block copolymers such as SBS and SIS. RIANOX 565 is also used in adhesives (hot melt, solvent-based), natural and synthetic tackifier resins, EPDM, ABS, impact polystyrene, polyamides, and polyolefins. RIANOX 565 is highly effective at low concentrations, matching the performance of other stabilizers at higher levels. It is non-staining and due to its low volatility, RIANOX 565 is not lost during polymer processing, drying or storage. RIANOX 565 can be used in a wide variety of applications. In unsaturated elastomers, RIANOX 565 prevents gel formation, maintains excellent polymer color, and prevents changes to molecular weight.

Rianox 1035

CAS#: 41484-35-9  |  RIA1035-CS

Rianlon Corp.

TDS

Rianox 1035 is a sulfur containing primary (phenolic) antioxidant and heat stabilizer used for the process stabilization of polyethylene wire and cable resins. The world’s most widely used antioxidant for PE and XLPE wire and cable resins, RIANOX 1035, provides efficient processing stabilization and long-term thermal stability with excellent system compatibility and low color. The high quality of RIANOX 1035 eliminates the concern over microcontaminants that can effect the insulation properties of the wire. RIANOX 1035 offers excellent heat stability and is very unlikely to exude. RIANOX 1035 prevents scorching of PUR flexible foams in combination with an aminic antioxidant and is used as a replacement for antioxidant BHT.
