It is majorly used as rubber curing accelerator with super anti-scorching and short curing time features. Used in manufacture of tires, shoes, tubes, cable, etc. |
| GRPC | TETD | Off white to White Flakes/ Powder | 69ºC - 73ºC | 0.1 - 2.0 | TETD is an accelerator suitable for most sulfur-cured elastomers. It acts as both an accelerator and a vulcanizing agent in low sulfur and sulfurless stocks. Its low melting point provides excellent dispersion in soft compounds. It is used as a cure modifier for polychloroprene. TETD provides better processing safety than TMTD with less blooming. |
| GRPC | ZDEC | Off white to White Powder | 175ºC Min. | 0.5 - 1.5 | ZDEC is used for NR, IR, BR, SBR, NBR, HR, EPDM and natural & synthetic latexes. Strong resistance to scorching. In its handling, care should be operated, because of its increase activation and strong tendency to scorch at low temperatures (100°C). ZDEC is often used as a secondary accelerator. In latex, better results are obtained when used in combination with other types, such as thiazole accelerators. Used for rubber coated fabrics, latex products and rubber cement, etc. |
| GRPC | ZDBC | Off white to White Powder | 104ºC - 110ºC | 0.2 - 2.5 | ZDBC is a rubber accelerator for natural and synthetic rubber and latex. Provides fast cures at low temperatures; slower cure rates than with ZDEC or ZDMC. It is mainly used as a non-blooming, non- staining ultra fast primary accelerator or as a boos ter accelerator in NR / Synthetic rubber latex compounds and dry rubber compounds for the manufacture of transparent / bright colored bloom free rubber products. |
| GRPC | ETU | White to pale crystalline Powder | 194ºC - 204ºC | 0.1 - 2.0 | ETU is an ultra-accelerator for polychloroprene rubber. It is also used in latex as a primary accelerator. It is active even at low temperatures. ETU can be used without zinc oxide for transportation articles. It is an antioxidant in adhesive systems. |
| GRPC | DPTU | Off white to White Powder | 145ºC - 150ºC | 1.0 - 2.5 | DPTU non-discoloring accelerator that provides rapid acceleration in most elastomers. It is effective at low temperatures and its vulcanizates have good heat stability. |
| GRPC | DPG | Off white to White Powder | 143ºC - 149ºC | 0.1 - 0.5 | DPG is a non-staining, non-discoloring, secondary accelerator for thiazoles and sulfenamides in NR and SBR compounds. It exhibits better storage stability than thiurams and dithiocarbamates but is not as active. DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silicoflouride foam process. |
| GRPC | TDQ | Light brown to brown Granules/ Powder | 80ºC - 95ºC | 0.5 - 1.5 | TDQ is an inexpensive and highly potent staining type antioxidant most widely used in the rubber com-pounds based on NR, IR, SBR, BR, NBR and other diene rubbers except CR (polychloroprene). TDQ is classified as a staining type, low volatility, and polymeric antioxidant with very high potency. It offers cost advantage since only small dosage is sufficient to obtain desired long term protection against heat and oxidative ageing as well as reversion resistance during over cure. |
| GRPC | MBI | Off white to White Powder | 295ºC - 300ºC | 0.5 - 1.5 | MBI is a non-staining secondary antioxidant for natural rubber, CR, SBR, NBR &EPR and prevents heat oxidation when used in combination with amines. |
