Dow RETAIN^™ Polymer Modifier

Dow RETAIN™ 3000 is a functional polymer which promotes compatibilization between polyolefins and polar polymers such as nylon and EVOH and blends of polar polymers. Dow RETAIN™ 3000 functions to enhance the dispersion of the polar polymers into the polyolefin matrix such that the haze of the resulting film structure is minimized. Dow RETAIN™ 3000 can be used in polyethylene or polypropylene base resins.

Dow RETAIN™ offers the following benefits: 

• Good compatibilization between polyolefins and polar polymers
• Wide range of processing and service temperatures
• For blown and cast film
• May be used in-line or pre-compounded

When used in multi-layer film scrap, Dow RETAIN can reduce gels, allow for retention of clarity and mechanical properties such as dart impact and tear resistance.

Dow RETAIN is used at a 1:1 ratio of compatibilizer to nylon barrier resin scrap and a 2:1 ratio of compatibilizer to EVOH barrier resin scrap.
