Plastics & Polymers Industry

Full-Service Supplier

Rock Chemicals, Inc. supplies bulk raw materials and specialty chemicals to plastics manufacturers, polymer producers, compounders, and converters. Whether you are producing thermoplastics, thermosets, elastomeric compounds, or specialty polymer formulations, the chemistry behind your process matters as much as the process itself. We supply the organic peroxides, flame retardants, plasticizers, process solvents, and specialty additives that plastic and polymer operations depend on.

Organic peroxides are among the most critical chemicals in plastics manufacturing, used as initiators in free-radical polymerization and as crosslinking agents in thermoset and elastomeric systems. Temperature stability, packaging, and reliable supply are non-negotiables when you are running peroxides. We carry a full range and can work with your team on the storage and logistics requirements that come with them.

Large Inventory and Short Lead Times

Our extensive supply chain gives us broad availability on the organic peroxides, flame retardants, and process chemicals your production requires. We offer flexible packaging, including temperature-controlled options for peroxides, and competitive pricing across both commodity and specialty products. Bundle packages are available to help you consolidate sourcing and reduce costs across your chemical inputs.

We believe in building a relationship with our customers that they can depend on for years to come and offer customized services that cater to your company's needs. Our response rates are often within the same business day, our products are cost effective and qualitative, and our customer service is personalized to meet your needs.
