Marshall Additives Technologies (MAT), a division of The R.J. Marshall Company, is a leading supplier of innovative and cost attractive inorganic flame retardant and smoke suppressant technologies for the plastics and rubber industries.
Backed by a customer focused Applications and R&D team, MAT is focused on developing and offering reactive combinations of inorganic flame retardant and smoke suppressant products with the aim of enhancing performance and/or reducing cost.
In addition, MAT offers the familiar single chemical products: Antimony Trioxide, Ammonium Octamolybdate, Alumina Trihydrate, Magnesium Hydroxide, Huntite / Hydromagnesite, Zinc Borate, Zinc Stannate and Zinc Hydroxy Stannate.
Products
There are three methods for flame retardance:
vapor phase inhibition, solid phase char formation, and quench and cool systems
that work by removing or reducing heat, fuel or oxygen.
Vapor Phase Inhibition
This approach works by removing flammable gaseous chemicals from the burning plastic. Chlorine and bromine based chemicals and polymers are used as the active flame retardants with MAT’s FLAME DEFENSE SERIES blends FD335, FD409, and FD440. Or with antimony trioxide using MAT’s FDAO.
Solid Phase Char Formation
MAT has developed a high performance low cost reactive blend to replace Ammonium Octamolybdate in a wide range of PVC applications. This product, Smoke Defense SD890 is particularly suited to plenum rated PVC formulations. Where a combination of smoke suppression and flame retardance is required in one product, MAT offers a range of Zinc based products.
Quench & Cool Systems
ATH, Huntite / Hydromagnesite, and Magnesium Hydroxide products are typically selected for halogen free applications and work according to two modes. Release of water and endothermic decomposition. Water release reduces temperature, excludes oxygen and combines with soot particles to reduce smoke. Endothermic decomposition removes heat energy from the combustion process.
Flame Retardant Solutions
We research, develop and manufacture a full line of inorganic flame retardant and smoke suppressant solutions to meet the most demanding requirements across the plastics and rubber industry. This is supported by our deep partnerships with suppliers, leading university departments and industry experts. Thus, allowing for a customer centered approach to support existing products and partnering on new applications or solving formulation challenges.
Commitment to Quality
Our commitment is to meet or exceed customer expectations by consistently:
- Fostering a culture of quality, safety, and continuous improvement.
- Partnering with suppliers to ensure consistent, high-quality materials and services.
- Using data-driven methods to manage and improve processes.
- Continuously enhancing our team’s skills through training.
- Prioritizing defect prevention over detection.
