In particular, They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost. Application: Light-colored, color and High-grade transparent rubber products.

SPECIFICATION: Appearance: White or Light yellow powdered crystal Available composition content :96% Min. M.P.: 89~94 °C Min.Loss on drying: 0.50% Max.Ash: 0.10% Max.Residues on 150μm sieve: 0Identification IR:Identical to standardProperty:It is white or yellow crystalline. It can be dissolved in acetone, benzene, toluene, ethyl ether and ethyl acetate as well as warm carbon tetra chloride, ethyl alcohol and heptane. It also can be slightly dissolved in gasoline, but not in kerosene and water. Application:The product may be used in natural rubber and synthetic rubber. It may protect effectively the rubber material from scorching during Processing, So that to make it possible for extruder and calender to be running at a high temperature and high speed and improve the production capacity of vulcanizer. The product also can improve the storage stabilization of the rubber material, protect natural vulcanization during storage. It has reclaimaion function for rubber material, which b

SPECIFICATION: Appearance: Light yellow powder Initial M.P.: 66.0 °C Min.Loss on drying: 0.40% Max.Ash: 0.30% Max.Residues on 150μm sieve: 0.50% Max.Oil content: 0; 1.0--2.0%PROPERTIES: No taste. Specific gravity: 1.27--1.31. Soluble in benzene, carbon disulphide, acetone And chloroform; Insoluble in gasoline and water.APPLICATION: A fast-curing primary or secondary accelerator for NR, SBR, nitrile and EPDM. Closely resembles Rubace TMTD in its applications. Less scorch and blooming, good processing safety. Can be used in CR as an anti-scorching agent.STORAGE: Keep container tightly closed in a cool, well-ventilated place. The recommended max storage life is 1 year when stored under normal conditions.

SPECIFICATION: Appearance: Yellow grain Initial M.P.: 78.0 °C Min.Loss on drying: 0.50% Max.Ash: 0.30% Max.PROPERTIES: Light yellow brownish powder, grain. Bitter taste. Specific gravity: 1.34--1.40. Soluble in benzene, acetone, methyl alcohol; insoluble in water.APPLICATION: An excellent delayed accelerator. The performance is similar to that of Rubace CZ displaying better scorch safety. Widely applied in NR, IR, SBR, NBR and EPDM. Can be applied alone or with those vulcanization accelerators such as thiurams, guanidines and dithiocarbamates to improve the activity. Mainly used in manufacture of tires, shoes and belts. Non-blooming. Not recommended to apply in beverage and food containers because of the bitterness of the product after vulcanization. STORAGE: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions.

Apearance: Green crystal with lustre Shade: similar to standard Tinting strength: 100% Moisture: 1.5% max. Insoluble matter: 0.05% max. Used for dyeing of silk, wool, cotton, paper, bamboo, weed, straw, leather, linen and some chemical fibers. Basic green is also used in making of color lake, solvent dyes and positive ion dyes.

Appearance: Grayish-white  powder Initial M.P.: 144.0  °C Min. Loss on drying:  0.30% Max. Ash:   0.40% Max. Residues on 150μm sieve:   0.10% Max. Oil content:  0; 1.0--2.0%PROPERTIES:No odor or poison. Specific gravity:1.13--1.23. Soluble in chloroform, toluene benzene and ethanol; Insoluble in gasoline and water. Not hygroscopic.APPLICATION:Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not as active. Rubace DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process.STORAGE:Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions
