• Leather cloth (PVC): Upholstery, Book binding. Seat covers
• Utility articles: Footwear, Raincoats, Handbags, Fiberglass, cellulose acetate
• Extruded articles: Cables (PVC & rubber), hoses, flexible pipe, coal mining, conveyor belts
• Coatings: Nitrocellulose lacquers, phenolic resins, lube oils

APPLICATION

Additives for surface coating

• TCP is used plasticizers for vinyl films in agriculture due to its weather resistance property
• Insulator compounds for electric cables and also in the synthetic rubber compounds.
• Lubricant additive and has been proven effective as mild extreme pressure addictive for synthetic oil.
• Based oil for fire-retardant hydraulic fluid for minimizing fire-risk from heat source or electric sparks.
• TCP is useful in the clear and dark coloured flame-retardant sheeting where pigmenting or opecifying flame retardants are undesirable
