Masterbatch adds pigments to vinyl functional polymers for LSR.Adding powder-based pigments, for example titanium dioxide or barium sulfate barium sulfate: see barite. , to silicone systems can be a messy and inaccurate process, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. Adding pigment to vinyl functional polymers Functional polymers are polymers with advanced optic and/or electronic properties. Advantages of functional polymers are low cost, ease of processing and a range of attractive mechanical characteristics for functional organic molecules. created an easy-to-use solid/liquid mass that can be added to elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. systems. This masterbatch typically contains a high percentage of pigment by weight so that additions to elastomers can be relatively small. Vinyl functional polymers participate in the addition cure reaction and tie in to the elastomer matrix as the material cures. Silicone masterbatches for high consistency rubbers use a high viscosity gum polymer, similar to those used in the company's high consistency silicone formulations. The resulting product has a consistency similar to many of the company's high consistency materials. MED2-4502 (for unrestricted healthcare applications) and MED2-4102 (for restricted healthcare applications) contain 75% barium sulfate. MED3-4502 (unrestricted) and MED3-4102 (restricted) contain 75% titanium dioxide. The company has developed a masterbatch specifically for liquid silicone rubbers Noun 1. silicone rubber - made from silicone elastomers; retains flexibility resilience and tensile strength over a wide temperature range synthetic rubber, rubber - any of various synthetic elastic materials whose properties resemble natural rubber , featuring a lower pigment loading level, in addition to lower viscosity polymers.
