The rubber molding industry has long grappled with odor issues stemming from sulfides, amines and plasticizer volatiles released during high-heat processes like vulcanization. High-temperature deodorizers have emerged as a transformative solution, addressing both environmental compliance and product quality demands.
These deodorizers operate through a triple mechanism that outperforms traditional masking agents. Their porous structure, often composed of modified activated carbon and natural minerals, first captures odor molecules. Catalytic components then convert these pollutants into harmless carbon dioxide and water, eliminating secondary contamination risks. Critical to their utility is exceptional heat resistance—top formulations withstand 150-200℃ vulcanization temperatures without decomposition, with some grades tolerating up to 400℃.
Compatibility across rubber types makes them versatile. They integrate seamlessly with natural rubber, nitrile rubber (NBR), EPDM and recycled rubber systems during mixing or molding. Adding just 0.3%-2.0% by weight achieves significant results, reducing odor levels from 4-5 to below 1 per GB/T 27755 standards.
Environmental and performance benefits further drive adoption. Certified under REACH and RoHS, they contain no heavy metals or harmful volatiles. Importantly, they preserve key mechanical properties—tensile strength, elasticity and wear resistance remain uncompromised, while product appearance stays consistent.
For manufacturers, these deodorizers resolve costly pain points: reducing workplace odor complaints and downstream product returns. As rubber recycling rates rise globally, they play a vital role in mitigating emissions from reclaimed materials. In essence, high-temperature deodorizers are not just additives but essential enablers of sustainable, high-quality rubber production.
