Rubber Accelerator CAS NO. 109-46-6 DBTU Applications

DBTU is an ullra-accelerator for mercaptan-modified CR(1-3phr). It has a vulcanizalion behaviour similar to that of ETU and DETU. It is also used as a secondary accelerator for NR and synthetic rubbers. It disperses easily in rubber. It is non-staining and does not bloom. It is practically odourless antioxidant for NR, antiozonant for NR and SR, particularly SBR. It is also a corrosion inhibitor.

Packaging & Shipping

Rubber Accelerator CAS NO. 109-46-6 DBTU: 

Package: 25kg plastic woven bag, paper with plastic film bag, 25kg drum.
Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The product with pallet should not be stacked. Stacking of palletized material or temperature of above 35 ºC can cause unusual compacted product. Since the date of production,the storage period is 12 months.




Sapphire Ball Lens

Ball lenses Spherical ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres fit into smaller packages.

Sapphire and Ruby ball lenses are both made from Al203. Ruby or Ruby-Doped sapphire owes its red color to traces of chromium oxide (chromium content for ruby balls is typically >0.5%). While their physical and chemical properties are basically the same, their optical properties are somewhat different. Sapphire has superior optical transmission qualities. Ruby Balls are easier to see and therefore easier to handle for physical applications.
