Plastics and Elastomers

Plastics and elastomers are susceptible to oxidative degradation during processing and in service. The oxidative degradation processes takes place as a result of radiation, temperature and oxygen on these materials resulting in reduced strength, embrittlement and shorter useful service life.

The degradation of plastics occurs during high temperature processing of these polymers involving injection molding, extrusion, and blow molding. Harsh environmental conditions also severely affect the service life of finished products. Normally antioxidants are added to polymers to prevent them from degradation. To be effective, these antioxidants need to be thermally stable and effective at these processing temperatures.

Recognizing the deficiencies in today's antioxidants, Polnox technologies produced new antioxidants possessing higher thermal stability and superior oxidative resistance

Higher Thermo-oxidative Resistance for Polnox PNX antioxidants

The superior performances of Polnox antioxidants, PNX are demonstrated for polyolefins using industry standard ASTM tests (D-3835) as compared to currently used antioxidant

Excellent Thermal Stability of Polnox PNX antioxidants

Several commercial antioxidants today are often very ineffective at processing or operating temperatures of materials due to their instability or voltalization. This has resulted in inadequate or no protection of materials at elevated temperatures.

Polnox antioxidants show superior thermal stability, thus providing new business opportunities that are not accessible today by current material antioxidants due to their thermal instability at elevated temperatures
