Manufacturers who work with plastic materials rely on plastic additives for various purposes. The ultraviolet (UV), thermal, and antioxidant stabilization properties of plastic additives offer cost-effective solutions for protecting plastic. They prolong the life of polymers in various plastics by protecting them from degradation in unfavorable environments. Here are the protective benefits of Phoenix Plastics’ UV, thermal, and antioxidant stabilizers.

Consider These Plastic Additives for Maximum Protection
Phoenix Plastics offers stabilizers that protect polymers from the harshest conditions. Below, manufacturers and other industrial companies can find which plastic additive products work best for their polymer protection needs.
UV Stabilization
Prolonged sun exposure shortens the lifespan of plastics. Over time, UV rays damage plastic by causing photooxidation. Surface polymers break down, resulting in color fading and material degradation.
The Cel-Span UVS 717 offers maximum UV protection that extends the life of plastics by 5-10 years. It contains Hindered Amine Light stabilizers, which continually replenish themselves while providing UV stabilization to polyolefins. This product is made from polyethylene and polypropylene resins. It is best applied to injection molding, blow molding, film, and sheet. The Cel-Span UVS 717 offers maximum UV protection that extends the life of plastics by 5-10 years.

UV stabilizers are particularly vital in sectors like construction, automotive, packaging, and agriculture, where plastic components are often exposed to intense sunlight for extended periods. By incorporating UV stabilizers such as Cel-Span UVS 717, manufacturers can maintain the appearance, strength, and function of plastic products, reducing the need for frequent replacement and cutting down on warranty claims due to degradation. Utilizing the right UV additive not only preserves aesthetics but also ensures compliance with industry standards and customer expectations.
Thermal Stabilization
Heat is one of the leading causes of polymer degradation in plastics. If plastic items are stored near heat-generating equipment, in the sun, or in other high-temperature environments, they will likely become prone to the breaking or cracking of the polymer molecular chains. This, in turn, leads to crosslinking and visbreaking, as well as the loss of physical properties.
Don’t let your plastics lose their form and strength in high-temperature environments. The Cel-Span S 310 thermal stabilizer contains compound antioxidants in its HDPE & LLDPE blends for maximum thermal stabilization. This plastic additive has a melting point of 190 degrees Celsius, making it perfect for molding, extrusion, and shutdown purge.
Thermal stabilizers play a crucial role during both processing and end-use. During molding and extrusion, thermal additives like Cel-Span S 310 prevent degradation caused by heat exposure, which can otherwise weaken the polymer matrix and create defects or discoloration in finished goods. Effective thermal stabilization not only increases the lifespan and performance of the plastic but also optimizes manufacturing efficiency, reducing waste and downtime related to heat-related failures.
Antioxidant Stabilization
Storing plastics out of the sun and away from high-temperature environments doesn’t always provide protection. Other factors, such as moisture, chemical exposure, and oxidation, often cause polymers to lose their physical integrity.
Consider the Cel-Span S 100’s anti-oxidant stabilization capabilities for plastic manufacturing and moderate-temperature storage. This plastic additive enhances the color of plastics and improves polymer durability. Made from polyolefin resins, it is ideal for extrusion and compounding.
Antioxidant stabilizers are designed to inhibit oxidative degradation, which is especially common during processing at elevated temperatures or over time while in storage. Without proper antioxidant additives, plastic products can suffer from loss of mechanical strength, yellowing, and brittleness. Products such as Cel-Span S 100 are engineered to combat these issues, safeguarding polymers against both immediate and long-term oxidative threats. Improving antioxidant protection is particularly important for products that will be subjected to recycling or multiple heating cycles, enhancing sustainability and lifecycle performance.
