jomarcorp.com info@jomarcorp.com 609-646-8000 The Jomar IntelliDrive TM series of injection blow molding machines capture the best in servo and hydraulic technologies. The IntelliDrive Series has now been expanded to include the Model 135 and Model 175 in addition to the original Model 85S. IntelliDrive IBM machines feature: • Energy savings of up to 50%* • Faster dry cycle times • Longer life for your molds • Less hydraulic oil usage (up to 40% less) • Less cooling water usage • Less noise and less vibration • 30 month warranty on hydraulic components (ask us for full details) *Energy consumption reduction contingent upon machine model, container specification, and material process. GET MORE PRODUCTION FOR LESS WITH THE JOMAR INTELLIDRIVE SERIES! Smarter injection blow molding. More production. Lower costs.

Filling a gap in the market, this unique additive allows BOPP and cast PP film to run about 30% faster in printing, laminating, and metalizing operations, according to the company. It also shows no migration of the slip agent—which can interfere with converting and affect the clarity of the film—after 18 months' storage. Unlike other slip additives, HMB-6301 is added only to the outer layer of BOPP film. It is stable over time and temperature, so its slip proper- ties are permanent (e.g., 0.2-0.3 CoF in film on film at 2-5 wt. %). The free-flowing pellet product is said to comply with EU and U.S. FDA food-contact regulations. • FR synergist for nylon: Introduced last spring, Dow Corning 43-821 additive is described as a novel solution to the drawbacks of using phosphorus-based additives in glass- reinforced flame-retardant nylon 6 and 66 used in electrical/ electronic applications. The phosphorus additives are nonmelting solids used at high loadings—typically 18-20%— which can degrade the compound's physical properties and flowability. Also, the phosphorus additives are acidic and can corrode connectors; and they are susceptible to accelerated aging that can cause embrittlement. New 43-821 Additive is a powder synergist for phosphorus additives (it's said to work well with Clariant's Exolit OP, for example) but it allows their loading to be reduced to 10-12%, which restores nylon's mechanical properties and processability and reduces corrosivity by cutting down the total phosphorus content. It also can reduce total cost of the compound by at least 10%. A loading of just 2% 43-821 Additive with 10% aluminum phos- phinate reportedly can achieve UL 94V-0 at 1.6 mm. Raising the phosphinate content to 13% meets V-0 at 1 mm. • Process aid for wire & cable: Dow Corning MB25-502 masterbatch is said to boost output by up to 25% of highly filled LDPE LLDPE, and XLPE wire and cable by decreasing extruder torque and minimizing die pressure and buildup. Introduced in early 2017, this product reportedly is more effi- cient than the older MB50-002 masterbatch but is still more economical than other high-performance process aids. 800-248-2481 • dowcorning.com @plastechmag 77 Plastics Technology N E W P R O D U C T S F O R P L A S T I C S P R O C E S S I N G
