Tin-coupled star-shaped block copolymer of styrene and butadiene (II) properties and application

Scopus: "A novel tin-coupled star-shaped block copolymer (SB-B)4Sn was synthesized by anionic polymeric techniques. This new copolymer exhibited two different types: One was star-shaped polybutadiene-b-poly (butadiene-ran- styrene) (S-PB-PSB), and the other was star-shaped polybutadiene-b- poly(butadiene-ran-styrene)-b-polystyrene (S-PB-PSB-PS). 

In this article, properties of (SB-B)4Sn were contrasted with that of tin-coupled star-shaped random styrene-butadiene rubber (S-SBR) and S-SBR/cis-BR blend rubbers. Physical property testing results showed that (SB-B)4Sn possessed good mechanical properties like S-SBR. Rheological study indicated that these star-shaped block copolymers had good processing properties. Rubber processing analyzer (RPA) spectra showed that the dispersion of additives in (SB-B)4Sn and S-SBR/cis-BR blend rubber was much better than that in S-SBR. Dynamic mechanical thermal analyzer (DMTA) spectra showed that (SB-B)4Sn had a good combination of low rolling resistance and high wet skid resistance, which made it satisfactory materials to produce high performance tire tread"

Synthesis and characterization of silicon nanowires using tin catalyst for solar cells application

Scopus : "Tin-catalyzed silicon nanowires were synthesized for solar cells application. Voluminous silicon nanowires were fabricated on single crystalline silicon wafer. Optical reflectance and solar cell efficiency of the synthesized silicon nanowires were explored. The reflectance of as-synthesized silicon nanowires was obtained approximately 5% in the short wavelength region (λ < 500nm)"

Timah completes design for tin chemical plant

Your Industry News: "Abrun added the company has just completed the design of a factory for tin chemical, which is used mostly in the plastics industry.

''We will begin the construction of this factory next year and we expect to finish it within less than one year.''

The tin chemical factory is designed to have a 30,000 ton capacity, but in early phases of production, the company would only aim for 10,000 tons, he added.

Timah has allocated about Rp 300 billion for this factory."

Could Tin Become The Gold Of Base Metals?

Factiva: "However, RCR expects the cost curve to shift down in 2009, due to lower labour and oil prices and notional input costs.

Tin suppliers have responded to this crisis by cutting production, with some smelters in China and Indonesia ceasing operation through December 2008 and January 2009. All up, LME stocks are now at a depleted level of about 9 thousand tonnes.

This leads the team at RCR to expect that tin will trade between US$9,000/t - US$15,000/t through 2009, with an average price of US$12,750/t, a 50% retrace from the May 2008 high of US$25,495/t. However, the analysts' long-term price forecast is for US$15,000/t, although this is contingent on a stable USD and reflects the potential positive effects of global economic stimulus packages."
