RIANOX 3114
A high molecular weight hindered phenolic primary antioxidant with outstanding photo- and thermo-stability. Provides very low volatility and excellent resistance to extraction from polymer compounds. Odorless and stable to light. Particularly effective when blended with RIANOX® 168 phosphite co-stabilizer.

Where RIANOX 3114 fits
RIANOX 3114 is a trifunctional hindered phenol built on an isocyanurate core (molecular weight 784, melting point 218–223 °C). It combines very low volatility, strong resistance to extraction and good light stability, and it is odourless. That makes it a strong choice where the antioxidant must stay in the part, in thin fibers or in parts that see water or long heat exposure. Typical uses:
- PP fibers, tapes and nonwovens
- Polyolefin pipe and parts exposed to water or extraction
- Polyamide and polyester compounds
- Elastomers and adhesives
Typical use levels
- Polyolefins: 0.05–0.2%, usually with RIANOX 168
- Fibers and long-term heat ageing: 0.1–0.3%
These are starting points. Confirm the level with multiple-pass extrusion (melt flow retention and colour) and oven ageing on your own compound.
Choosing a phenolic antioxidant
How RIANOX 3114 compares with the other hindered phenols we supply:
| Grade | Structure | Mol. weight | Melting point | Best known for |
|---|---|---|---|---|
| RIANOX 1010 | Tetrafunctional phenol | 1178 | 110–125 °C | General-purpose long-term heat stability |
| RIANOX 1076 | Monofunctional, C18 chain | 531 | 50–55 °C | Compatibility and low colour in polyolefins |
| RIANOX 3114 | Isocyanurate trisphenol | 784 | 218–223 °C | Very low volatility, extraction resistance |
| RIANOX 1790 | Isocyanurate trisphenol | 700 | 155–165 °C | Low colour and gas-fade resistance; fibers |
| RIANOX 245 | Asymmetric phenol | 587 | 77–81 °C | Styrenics, POM and polyurethane |
Pairing RIANOX 3114 with co-stabilizers
A phenolic antioxidant traps free radicals but does not remove the hydroperoxides formed during melt processing. Pair RIANOX 3114 with RIANOX 168 phosphite for processing stability and colour, and with RIANOX DSTP thioester for long-term heat ageing. For outdoor parts, add a HALS light stabilizer, and keep thioesters low when you do, because their acidic by-products weaken HALS. Our HALS UV stabilizer guide explains why.
