Antioxidant and SIS Thermoplastic Rubber Pelletized Blend is a non-discoloring stabilizer. Can be used the in the manufacture of hot-melt pressure sensitive adhesives (HMPSA) using single or twin screw extruders.
Provides good long-term heat stability, good compatibility with resins and good extraction resistance.
Benetex® OB by Mayzo is an optical brightener, fluorescent whitening agent. Heat resistant, chemically stable fluorescent whitener that provides brighter looking colors. Used to offset the yellowness of a polymer and to yield a whiter appearance. Creates brilliance by absorbing UV light, modifying the wavelength of the light and then emitting the light in a fluorescent fashion. Benetex® OB can be used to impart brightness to various thermoplastics, including: polyvinyl chloride, polyethylene, polypropylene, cellulose acetate, polystyrene, linear polyester, and polyamides.
BNX® 1225 TPR by Mayzo is 45:55 blend of tetrakis [methylene-3 (3’, 5’-di-tert-butyl-4-hydroxyphenyl), tris (2, 4- di-tert-butyl phenyl) phosphite and styrene-isoprene-styrene thermoplastic rubber. Acts as an antioxidant. This blend of both a primary and secondary antioxidant provides excellent heat stability, good compatibility with resins as well as excellent extraction resistance. Its SIS (styrene-isoprene-styrene) thermoplastic rubber has a styrene content of 14%, diblock content of 12% and a melt index of 9. Compatible with other SIS thermoplastic elastomers such as Quintac® 3620, Kraton D1161P, Kraton D1193, Enichem ST-190, and Vector 4113. Its pellets are durable enough for air conveying due to which does not break-up. Offers increased processing efficiencies such as reduced handling time and minimal screw slippage. Also offers uniform shape and size. BNX® 1225 TPR is used in the manufacture of hot-melt pressure sensitive adhesives (HMPSA) using single or twin-screw extruders. Its feed rate should be 0.4% to 2%.
