Durastrength® 350

Because it was developed with the customer in mind, Durastrength® 350 brings a wealth of benefits to compounders and manufacturers such as:

• Durastrength® 350 impact modifier provides superior long-term weather resistance while retaining impact resistance and color retention.
• Durastrength® 350 impact modifier imparts excellent room temperature impact resistance while maintaining industry required low-temperature impact resistance.

 Izod Impact (Window Profile Formulation)

• Durastrength® 350 impact modifier provides a broad process window allowing flexibility in processing temperature and output.
• Durastrength® 350 impact modifier offers faster fusion over competitive acrylic impact modifiers without the need for additional process aids.

 Fusion Time Versus Processing Temperature

Durastrength® 350 impact modifier is ideally suited for vinyl window profile, siding, fencing, decking, pipe, and conduit. The low melt viscosity and rapid fusion characteristics of Durastrength® 350 impact modifier are also ideal for difficult injection molding applications.

Durastrength® 350 impact modifier is recommended for use in tin, lead, and mixed-metal stabilized profile applications where enhanced room and cold-temperature impact resistance is required. As with all impact modifiers for PVC, proper formulation is required to develop the proper shear and mixing during extrusion so that impact properties are optimized.

Durastrength® 350 impact modifier is packaged in 50lb bags and1800lb bulk bags.
