Application Characteristics

Crystalline Powder CTP

N-Cyclohexylthiophthalimide

White to light yellow crystalline powder

89-94

An effective scorch inhibitor for conventional vulcanization systems of natural and synthetic rubber, especially suitable for systems containing sulfenamide accelerators, such as tires, hoses, conveyor belts, and other rubber products.

Oil-Extended Powder CTP

N-Cyclohexylthiophthalimide oil-extended 0.2-1.0%

White to light yellow crystalline powder

88-92

An effective scorch inhibitor for conventional vulcanization systems of natural and synthetic rubber, especially suitable for systems containing sulfenamide accelerators. Oil extension improves the dispersibility of CTP, used in tires, hoses, conveyor belts, etc.

Filler-Isolated CTP

N-Cyclohexylthiophthalimide inert filler 2-5%

White to light yellow crystalline powder (80 mesh)

89-94

An effective scorch inhibitor for conventional vulcanization systems of natural and synthetic rubber, especially suitable for systems containing sulfenamide accelerators. Filler isolation improves the dispersibility of CTP and prevents caking during storage and transportation. Suitable for tires, hoses, conveyor belts, and other rubber products.

Wet Granulation CTP

N-Cyclohexylthiophthalimide organic carrier 1%

White columnar granules

88-92

An effective scorch inhibitor for conventional vulcanization systems of natural and synthetic rubber, especially suitable for systems containing sulfenamide accelerators. Wet granulation enables automatic dosing and reduces dust generation. Suitable for tires, hoses, conveyor belts, and other rubber products.

Special Scorch Inhibitor for EPDM, etc. Oil-Extended Powder V.E/C

92% Benzenesulfonamide derivative 6% inert filler 2% oil-extended

Inert filler-coated white powder

~110

An effective scorch inhibitor for rubber vulcanization systems with various accelerators, such as EPDM. Improves scorch safety without reducing vulcanization torque and modulus of vulcanizates, and improves compression set. Suitable for EPDM automotive sealing strips.

Scorch Inhibitor for ECO, ACM/AEM Powder ZDOP

70% High molecular weight zinc dialkyldithiophosphate 30% mixture of inert filler

Free-flowing white powder

—

Scorch inhibitor for chlorohydrin rubber ECO, acrylate rubber ACM/AEM/EVM, etc. Suitable for injection molding and continuous extrusion vulcanization of these rubbers.
