Dupont™ MULTIBASE™ silicone masterbatch additives

MULTIBASE^™ thermoplastics additives contain high or ultra-high molecular weight siloxane, pre-dispersed and/or reacted in a range of polymer-carriers and specially engineered to deliver multiple benefits for greater design freedom and production efficiencies, including:

• Improved scratch, mar and abrasion resistance
• Decreased coefficient of friction
• Reduced squeaking noises
• Optimized fillers dispersion
• Improved processability (e.g., decreased energy consumption, reduced build up, improved mold release)
• Provides long-lasting performance stability enabling the design of more durable parts

MULTIBASE^™ plastics additives support extended lifespans for end applications, enable more effective manufacturing by reducing energy consumption and scrap, and often permit lower-complexity formulations in support of recyclability.

MULTIBASE ^TM additives for Thermoplastic Vulcanizate (TPV) compounds

Improved slip performance and scratch resistance after aging without blooming.

Silicone-based additives specifically developed to support Flexible packaging and Film producers

A major challenge in transitioning from rigid to flexible packaging formats is the fill line speeds. New generations of vertical form-fill-seal machines (e.g., VFFS, etc.) have set new standards in production speeds and sealing techniques, and are prompting plastic film processors to seek new ways to optimize production efficiency, control costs, and simplify supply chain management to meet tighter delivery schedules.

Stable, long-lasting slip additives are critical for reducing stress on low density polyethylene (LDPE)-blown films and biaxially oriented polypropylene (BOPP) films used in high volume for high-speed form-fill-seal (FFS) packaging operations. Lowering the coefficient of friction (COF) on film surfaces can boost productivity and ensure consistent film quality and reduce throughput interruptions.

Organic slip additives or migratory slip additives have been the traditional choice. But they have significant drawbacks. Their efficiency can be compromised over time, such as when heat is applied during the conversion steps. Also, because these additives migrate, some molecules can transfer and impact printability or other post-process operations on the opposite layer.

As non-migrating agents, MULTIBASE^™ additives address these challenges, offering key benefits for film producers and processors including:
