The polymer industry depends on chemical additives. Without them, plastics would degrade in sunlight, burn readily, crack in cold temperatures, and fail within months of production. Polymer additives, plasticizers, flame retardants, UV stabilizers, antioxidants, processing aids, and colorants, are what make modern plastics functional, durable, and safe.
These additives ship in liquid bulk from chemical manufacturers to polymer compounders and plastic product manufacturers. The logistics are more complex than standard chemical shipping because polymer additives span a wide range of chemistries, hazmat classifications, and handling requirements.

Major categories of polymer additives
Plasticizers
The highest-volume polymer additive category. Plasticizers make rigid polymers flexible, primarily PVC. Products include phthalate esters (DEHP, DINP, DIDP), non-phthalate alternatives (DOTP, citrates, adipates), and bio-based plasticizers. Most ship as non-hazardous liquids requiring clean equipment and strict product segregation between phthalate and non-phthalate types. For specific shipping requirements and regulatory considerations, see our guide to plasticizer types and regulations.
Flame retardants
Chemicals that reduce the flammability of polymers. Includes halogenated flame retardants (brominated and chlorinated compounds), phosphorus-based flame retardants, and mineral flame retardants. Some carry DOT hazmat classifications, particularly halogenated and phosphate ester types. Regulatory scrutiny is increasing, creating product segregation requirements similar to phthalate plasticizers. For more on equipment and compliance specifics, see our flame retardant shipping logistics guide.
UV stabilizers and light stabilizers
Protect polymers from UV degradation. Includes UV absorbers (benzotriazoles, benzophenones), hindered amine light stabilizers (HALS), and quenchers. Most ship as liquids or solutions. Some formulations carry hazmat classifications. For more on shipping requirements and polymer protection chemistry, see our UV stabilizer and light stabilizer shipping guide.
Antioxidants
Prevent oxidative degradation of polymers during processing and service life. Includes phenolic antioxidants and phosphite/phosphonite processing stabilizers. Most ship in liquid form to compounders for direct addition during pellet production.
Processing aids
Improve polymer processing characteristics, flow, mold release, die build-up prevention, and surface quality. Includes lubricants, slip agents, antiblocking agents, and mold release agents. Some processing aids overlap with surfactant chemistry. Equipment cleanliness is critical to prevent cross-contamination between different additive types.
Related to polymer additives, manufacturers of rubber and elastomer products also rely on a parallel set of bulk chemical inputs. For shipping elastomer raw materials and related rubber chemistry, see our elastomer chemicals shipping guide.
Shipping considerations for polymer additives
Product segregation. The polymer additive market is increasingly segmented by regulatory status. Phthalate vs. non-phthalate, halogenated vs. non-halogenated flame retardants, SVHC vs. non-SVHC substances, cross-contamination between regulated and non-regulated products can make an entire shipment non-compliant. Tank wash verification and prior cargo documentation are essential.
Hazmat classifications. Classifications vary widely across the additive spectrum. Many are non-hazardous. Others are DOT Class 3 (flammable), Class 6.1 (toxic), Class 8 (corrosive), or Class 9 (miscellaneous). Each shipment requires verification against the specific product SDS.
Temperature management. Some polymer additives are viscous at ambient temperature, particularly plasticizers and certain flame retardant formulations. Winter shipping may require heated or insulated equipment for pumpability.
Purity requirements. Polymer additive specifications are tight. Contamination affects additive performance and can compromise the finished plastic product. This makes tank cleanliness and prior cargo verification more critical than for most commodity chemicals.

Frequently Asked Questions
What are the main types of polymer additives?
Plasticizers (flexibility), flame retardants (fire resistance), UV/light stabilizers (UV protection), antioxidants (oxidation prevention), and processing aids (flow, mold release, surface quality). Each category has multiple sub-types with different chemistries and shipping requirements.
Are polymer additives hazardous materials?
Some are, some aren't. Classifications range from non-hazardous to DOT Class 3, 6.1, 8, or 9 depending on the specific chemistry. Each product must be verified against its SDS.
Why is product segregation important for polymer additive shipping?
Regulatory changes are creating strict divisions, phthalate vs. non-phthalate, halogenated vs. non-halogenated. Cross-contamination during shipping can make a non-regulated product non-compliant for its intended application. Tank wash and prior cargo verification prevent this.
Does Total Connection ship all types of polymer additives?
Yes, plasticizers, flame retardants, stabilizers, antioxidants, and processing aids. We handle the product segregation, hazmat compliance, and purity requirements that polymer additive logistics demand.
