Recently, Baling Petrochemical's patent of "An Injectable Foamable Styrene Monomer-Diene Copolymer and Its Preparation Method and Use" won the China Patent Excellence Award
.
The patent was jointly applied for and authorized by Liang Hongwen, chief expert of Baling Petrochemical, and invented a new structural polymer in response to the problem of uneven foam cells caused by the uneven dispersion of foaming agent during the processing of traditional SBS rubber An important breakthrough in SBS rubber synthesis and application technology has solved the key and common technical problems in the preparation and application of SBS rubber
.
The SBS rubber material produced by this patent has injectable foaming properties, and excellent product stretch, tear strength and wear resistance that other SBS rubbers do not have, while still having the renewable processing characteristics of other SBS rubbers.
This patented technology was industrialized in 2009 on the first domestic SBS plant with an annual output of 200,000 tons of thermoplastic rubber in the Baling Petrochemical Rubber Department
.
The product is mainly used for foaming soles, which overcomes the complex processing of traditional vulcanized rubber soles and the disadvantages of SBS soles in temperature resistance, solvent resistance, abrasion resistance and the need to spray paint on the surface.
On the basis of this patented technology, the patentee has applied for 13 peripheral patents around the downstream application technology of styrene monomer-diene copolymers, forming a complete intellectual property protection system, and derived non-tire solution polymerization Styrene-butadiene rubber (SSBR) series products include 14 grades including SSBR for plastic modification, SSBR for adhesives, and SSBR for asphalt modification
