First Rubber TPK is a highly efficient, non‑toxic, and non‑staining aryl secondary amine antioxidant, widely recognized as AO‑445. Its high molecular weight and low volatility deliver superior long‑term thermal and anti‑ozonant protection compared to conventional phenolic antioxidants (SP, 1010, BHT). TPK is compatible with NR, SBR, BR, NBR, CR, and EPDM, making it an ideal solution for automotive components, industrial hoses, wire & cable sheathing, and other demanding rubber applications. It also exhibits an excellent passivation effect on heavy metal catalysts, and can be used alone or synergistically with other sulfur‑containing antioxidants.

Many rubber engineers assume that amine‑based antioxidants cause staining and discoloration. TPK is different. It is an aryl secondary amine antioxidant with high molecular weight and low volatility — and most importantly, it is non‑staining and non‑discoloring. In CR, ACM, EPDM — polymers where colour and surface appearance matter — TPK can be used without worrying about bloom or yellowing under sunlight. Compared to traditional phenolic antioxidants like SP, 1010 or BHT, TPK offers much better long‑term thermal stability. Its high molecular weight keeps it from volatilising during high‑temperature processing or extended service life. TPK also has a hidden strength: metal deactivation. If your compound contains trace amounts of copper, manganese or other heavy metals (common in reclaimed rubber or certain fillers), TPK helps inhibit their catalytic effect on rubber degradation. This is particularly useful in wire & cable sheathing and automotive sealing applications. It also works well together with sulphur‑containing antioxidants (e.g., MB series), offering better synergy than either product alone. Typical dosage is 0.5–3.0 phr, with 1–2 phr being the most common range. TPK is not a revolutionary product. But it is a dependable, high‑performance antioxidant that simply works. If you need long‑term heat resistance, no staining, and no colour change, TPK deserves a spot on your shortlist. Typical reference data: - Chemical name: 4,4'‑Bis(α,α‑dimethylbenzyl)diphenylamine - Appearance: Off‑white to light yellow powder - Non‑staining: Yes - Volatility: Low - Recommended dosage: 0.5–3.0 phr (typical 1–2 phr) - Packaging: 25 kg paper bag or carton - Storage stability: 12 months in unopened packaging under cool, dry conditions Samples and technical data sheets are available. No hard selling — just for your evaluation.
