Unique thermostable, high-strength, exceptional chemical and Inquiry (采购产品): Unique thermostable, high-strength, exceptional chemical and flame resistant thermosetting resins (Rolivsan & Zaitform resins) Gentlemen, For a long time we have developed and produced proprietary unique vinyl ester resins (ROLIVSAN & ZAITFORM RESINS) of a new type capable of the chemical transformations (crosslinking and the ring formation) to thermally stable polymers during the cure. For more details see please our web sites: http://www.private.peterlink.ru/zaitsev/index.html , http://www.private.peterlink.ru/schwab/index.html They are non-toxic liquid or low melting solvent free resins (with controllable and intended viscosity ranging from 80-100 to 3000-5000 cps at RT) that are easy-to-process to different high temperature (Tg 270° to 330°C) flame retardant and non-porous advanced polymer materials (sealant, impregnating compounds, adhesives, coatings, binders, glass and carbon fiber composites) exhibiting exceptional chemical resistance (to hot strong alkali, hot strong acids (including HF solution), hydrazine, etc., and to galvanic corrosion), low density (~1.15 g/cc), excellent dielectric characteristics (E~ 36 kV/mm, ? = 2,9-3,3, Rv = exp14 Ohm.m, tg ? = 0.001). Rolivsan & Zaitform resins are produced to electrical engineering and electronics for application both neat resins and compositions with epoxy, vinyl ester and polyester resins. The interested Parties are invited to negotiation, licensing, and/or collaboration including a support of our new project aimed at revolutionary improving of their cost-effectiveness (next generation of the resins). As a subject for scientific collaboration, rolivsan-epoxy compositions are capable to provide a fascinating instrument (long-term thermally stable and reactive medium with controllable viscosity at 80-140°C in the range from ~1 to 103-104 cps, and higher … up to solid state of matrix) for studying and creating high-strength thermosetting polymer materials and composites which combine high temperature performance with enhanced fracture toughness, for example. The general synthetic and processing goal could be the formation of controlled suspended solid (from a nano- to a micron-sized) particles (domains, crystallites, crosslinking volumes) by means of conducting a step-growth polymerization and/or a crystallization process in such an reactive liquid resin that can be quickly converted into high temperature matrix (interpenetrating polymer network) for the fixation of the intended structure (morphology). We would greatly appreciate if you could inform us about right contacts. Thank you in advance. With best regards, Boris A. Zaitsev, Developer and patentee, Ph.D, D.
