Sulfurized Isobutylene SDT321
★ Properties and Applications
Sulfurized isobutylene, as yellow oily transparent liquid, has strong extreme pressure properties, good oil solubility, low corrosion and little usage, and is widely used for gear oil, metal processing oil, antiwear hydraulic oil and lubricating grease.
Molecular formula: C8H16S3
Molecular weight: 208.39
Specific gravity d420: 1.1~1.2
★ Features
1. Sulfurized isobutylene is produced by adopting advanced, reasonable and mature production technology, and independently develops sulfurized isobutylene products with different grades.
2. By conducting strict quality monitoring on raw material and entire production process and can produce as many as 30 test items in the production link, fully ensuring product quality.
3. The product is not added with base oil, so it is honored as “original ecology” product.
4. Complete and effective environmental supporting facilities have been completed, laying a solid foundation for stability and development of the company and sulfurized isobutylene products.
5. The product is exported to Middle East, Europe and America, obtaining wide market recognition.
★ Grades: SDT321 universal sulfurized isobutylene accords with SH0664-1998 321 Extreme Pressure Additive Standard.
★ Packaging and Storage
1. Packaged by 1.2 galvanizing barrel, net weight 200±
2. Stored in a cool and dry place, fireproof, moistureproof, sunscreen, screw the barrel lid (avoid contact with air).
3. Prohibit direct stacking with metal and hard object during transport or mixing with corrosive object.
SH0664-1998 universal implementation of the company in the industry SDT321 Extreme Pressure Additive Standard on the basis of improved quality requirements, developed a vulcanizing isobutylene enterprise standard higher than the current standard.
