Retain 3000

За овој производ

RETAIN™ 3000 is a functional polymer which promotes compatibilization between polyolefins and polar polymers such as ethylene vinyl alcohol (EVOH) and polyamide (Nylon) and blends of polar polymers.

RETAIN™ 3000 is a unique technology designed to effectively compatibilize polar and non-polar polymeric components typically found in recycle streams. This compatibilizer was developed using Dow's expertise in material science and reactive chemistry to compatibilize two otherwise immiscible materials while maintaining critical physical properties.

Composition

• Ultra High% By Weight Maleic Anhydride
• Graft levels are defined as:
• Low < 0.2%; Medium 0.2-0.5%; High 0.5-1.0%; Ultra high > 1.0%

Features

• Pellets are dusted with an anti-massing agent.

Characteristics / Benefits

• Good compatibilization between polyolefins and polar polymers

• Wide range of process and service temperature

• For blown and cast film

• May be used in-line or pre-compounded

• RETAIN™ 3000 disperses polar polymers into the polyolefin matrix and decreases the size of polar domains which results in lower haze. This applies for both polyethylene and polypropylene dominant streams.

Applications

• RETAIN™ 3000 is most specifically designed to compatibilize polyamide (nylon) and ethylene-vinyl alcohol (EVOH) into a continuous polyethylene matrix.

• These polymers achieve their functionality by reacting with the polar polymers and then efficiently dispersing them into the polyethylene majority matrix.

• Due to the complex nature of a recycle stream, the typical properties reflect those found in select instances but serve as a guide for anticipated properties while recognizing that the reprocessing equipment selected will define the ultimate utility of the compatibilizer. Additionally, the level of recycle compatibilizer needed to achieve maximum physical properties is dependent on the amount and type of polar polymer present in the recycle stream.
