Antioxidants Prevent thermal degradation and provide long term stability Antioxidants help preserve the appearance and physical properties of polymers. Ampacet offers two categories of antioxidants, each with a specific function in polymer stabilization: Primary antioxidants are used to protect the finished product. This ensures performance over the life of the finished good. Secondary antioxidants are used as process stabilizers. They protect the polymer during processing, especially when the polymer undergoes multiple heat histories. Antioxidants are also designed to protect recycled polyolefin (rPE) resins and minimize gel formation and yellowing, protecting the aesthetics and mechanical properties of secondary packaging for higher shelf appeal, allowing higher use of rPE. Primary/Secondary blends are often used to protect polymers during their entire lifecycle. Antioxidants allow for reduced use of virgin resin, reuse of internal waste, and lifecycles of PCR that undergoes many heat histories. To avoid pinking or yellowing, proper selection of antioxidants and co-additives is required. Click here for more details.

Purge and Shutdown Additives Save lost time and reduce waste during clean outs Purge masterbatches are designed to mildly scrub out your processing equipment during extrusion between jobs to accelerate old resin and colorant removal. Shut-down masterbatch is used to reduce the likelihood of polymer degradation from occurring due to your extrusion equipment. Ampacet offers several purge and shutdown products to save time and reduce waste in processing. 100400 Purge PE masterbatch: a mildly abrasive transition purge for molding and extrusion equipment NaturBlend™ 103828 Universal Purge: specially designed to purge out non-compatible materials such as polyethylene mixed with nylons 100401 Antioxidant PE masterbatch: a shutdown compound designed to reduce oxidation of polyolefins remaining in the extruder during shutdown, start-ups and screen pack changes For more information on Ampacet Purge and Shutdown products, their applications and complete Regulatory Status, please complete the product inquiry form or contact Ampacet or your local Ampacet representative.
