Flame Retardant

Halogenated FR


Optimal Tech Co., Ltd. is one of leading flame retardant distributors in Thailand. We supply a wide range of flame retardant additive for plastics, textiles, surface finishes and coatings.


Flame retardants play an important role in fire prevention and suppression. Strict fire safety standards reduce the detrimental impact of fires on people, property, and the environment.

Flame retardants not only prevent fires from starting, but if a fire does occur, they slow down the spread of the fire and enhance the opportunity time for safe escape.


There are several chemical classes of flame retardants used with polymers, such as:​

  • Halogenated Flame Retardant (Brominated Flame Retardant)

  • Phosphorus-based Flame Retardant

  • Ammonium Polyphosphate Flame Retardants

  • Melamine based Flame Retardants

  • Metal Hydroxide Flame Retardants, Synergist and Smoke Suppressants

  • Silicone based Flame Retardants 


Optimal Tech Co., Ltd. is the official distributor of Lanxess Corporation who is one of the world’s leading manufacturers of bromine, bromine intermediates, and brominated flame retardants.

LANXESSs brominated flame retardants have a long history of providing outstanding flame retardant protection. They are used in a wide variety of applications from electronic housings, to printed wire boards and electrical connectors to flexible and rigid insulation & construction foams.


Brominated Flame Retardant is the most used class of flame retardant. This family of flame retardants is very versatile and provides outstanding flame retardant protection. Also, it provides optimal processing while maintaining outstanding physical properties in a cost-effective manner. Brominated flame retardant is incorporated in the plastic especially in thermoplastics such as PP, PE, ABS, HIPS, PS, PC and thermoplastic polyesters.

We offer a comprehensive range of brominated flame retardant for variety application;

Ammonium Polyphosphate FR

Metal Hydroxide Flame Retardant

Metal Hydroxide Flame Retardant

Smoke Suppressants Synergist

Optimal Tech Co., Ltd. supply a wide range of halogen free flame retardant such as metal hydroxide flame retardant, smoke suppressant and synergist chemical of halogenated FR. Optimal Tech is authorized distributor of metal hydroxide flame retardant and smoke suppressant from Century Science & Technology Group, China. Also, we supply antimony trioxide (ATO) which is the synergist chemical of Halogenated flame retardant from Gredmann Group who is leading provider of antimony trioxide in the global flame retardant market.

Metal Hydroxide Flame Retardants are the commonly used family of Halogen Free Flame Retardants. These mineral compounds are used in polyolefins, TPE, PVC, rubbers, thermosets and can also be used in some engineering polymers such as polyamide. 

  • Alumina Trihydroxide - ATH (Al2O3)     : Suitable for processing temperature under 200°C.

  • Magnesium hydroxide (Mg(OH)2)         : Suitable for processing temperature exceeds 200°C

Smoke Suppressants


We supply Zinc Borate which is one multi-functional synergistic flame retardant in polymers to improve flame retardant performance, it can reduce smoke evolution and adjust the balance of flame retardant properties versus mechanical, electrical and other properties.


Our Zinc Borate is widely used in PVC applications such as carpet, conveyor belt, wire and cable, and in Nylon, polyolefin and engineering plastics. We have standard grade and smallest particle size for special applicates.



Synergist Chemical

Antimony trioxide (ATO) is the synergist acts to improve the activity of the additive in the polymer, thus lowering the amount of halogenated additive needed. ATO acts as a halogen shuttle bringing SbX3 into the vapor phase.

  • ATO GM-F



Silicone Based Flame Retardant

Optimal Tech Co., Ltd is the distributor of Momentive Performance Materials who is leading silicone manufacturing. They supply a wide range of industries including automotive, electronics, personal care, consumer products, aerospace and building and construction.


Our silicone flame retardant is a high viscosity silicone containing a combination of a linear silicone fluid and a silicone resin that is soluble in the fluid. It can be considered for polyolefins and thermoplastics use to help impart flame retardancy and anti-drip. It is a non-toxic FR additive whose synergistic property allows for lower loadings of non-Si additives, increases process ability, and improves mechanical properties. Also, silicone flame retardant offer is excellent flame retardant in PC with high miscibility to allow optical transparency in clear PC.
