Tris(2-chloroisopropyl)phosphate (TCPP)

TCPP is an organic phosphorus halogen flame retardant widely used in various applications. It is soluble in alcohols, benzene, esters, carbon tetrachloride, and other organic solvents, but insoluble in water and aliphatic hydrocarbons. TCPP has excellent oil resistance and hydrolytic stability. Due to its molecular structure containing phosphorus and chlorine elements, it exhibits significant flame-retardant properties.
TCPP also acts as a plasticizer, moisture-proof agent, and antistatic agent, and has good UV resistance, which is extensively applied as a flame retardant in flexible and rigid polyurethane foams (PUR and PIR), polyvinyl chloride (PVC), polyvinyl acetate (PVAc), phenolic resins, epoxy resins, and other materials. Products containing TCPP not only exhibit self-extinguishing properties but also improve light resistance, water resistance, and antistatic properties, and enhance the gloss of the products.
TCPP can be used directly or formulated into an emulsion for applications in carpets, raincoats, fabric finishing, and rubber products, and can also be used in fire-resistant coatings and additives. In rigid polyurethane foams, TCPP’s excellent thermal conductivity and hydrolytic stability allow formulations to meet basic fire standards such as ASTM E84-00 (Class II). It can also be used in polyurethane foams, unsaturated resins, and phenolic plastics to reduce viscosity at low temperatures. It is typically used in combination with antimony trioxide to improve flame retardancy.
The typical dosage in soft and rigid polyurethane foams is 10-15%, and its flame retardant performance is superior to TCEP.

Specific applications are as follows:

• In polymer materials

TCPP is widely used in various polymer materials such as polypropylene, polyethylene, polyvinyl chloride, polybutadiene, and polystyrene. It can be physically blended or chemically blended with polymers to effectively enhance the flame retardant performance of the materials, reduce smoke and toxic gas emissions during combustion, and protect personal safety while minimizing property losses.

• In polyurethane materials

TCPP can be used as a flame retardant in polyurethane materials. Polyurethane is an important engineering plastic known for its excellent mechanical properties and abrasion resistance, and it is widely used in automotive, construction, electronics, and other fields. Adding TCPP can significantly improve the flame retardant performance of polyurethane materials, slow down the burning rate, reduce smoke generation, and increase the fire rating of the materials.

• In coatings and adhesives

TCPP can also be used as a flame retardant in coatings and adhesives, which are widely used in construction, marine, aerospace, and other fields, where flame retardancy requirements are high. Adding TCPP can effectively enhance the flame retardant performance of coatings and adhesives, reduce the occurrence of fire accidents, and protect personnel and property safety.

• Package and Storage

TCPP is typically packaged in iron drums with a net weight of 250 kilograms, IBC drums with a net weight of 1000-1250 kilograms, or ISO tanks with a capacity of 20-25 tons.
