Viton FreeFlow - 10 - Pellets for Fluoroelastomer Datasheet

Technical Information • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Rev. 2, June 2002 Viton® FreeFlow™ 10 Description Viton® FreeFlow™ 10 is a fluoroelastomer additive in pellet form. It can be added to high density polyethylene (HDPE), linear low density polyethylene (LLDPE), or polypropylene (PPE). Advantages • Process improvements in all types of polyolefins including HDPE, low density polyethylene (LDPE), LLDPE, and PPE • Elimination or minimization of surface imperfections (e.g., melt fracture) • Reduction of die pressure, power requirements, and temperature • Increased output (at constant die pressure and temperature) • Improved properties when narrow dies are used in place of wide dies to reduce orientation Formulation Guidelines To assist in resin formulation, the following can be used as a general guide: Elimination of Sharkskin Melt Fracture In standard film resins, ppm 300–600 In heavily filled or pigmented film, ppm 600–1,200 Reduction of die buildup, ppm 100–250 Levels are parts per million Viton® FreeFlow™ 10 These numbers are intended to be starting points for formulation. The actual level required will depend on a multitude of factors. Typical Physical Properties Appearance Silver gray to pale amber free-flowing pellets Packaging 25 kg boxes Specific Gravity 1.81 ± 0.03 Shelf Life, yr 4* * Normal storage conditions—dry, unopened, temperature below 27°C (80°F) Safety and Handling Viton® FreeFlow™ 10 is considered a safe material to handle. It is stable at the temperatures at which polyolefins are formulated and processed. However, prior to the use of Viton® FreeFlow™ 10 in polyolefins, review the Material Safety Data Sheet (MSDS) and follow the recommendations in DuPont Performance Elastomers bulletin “Handling Precautions for Viton® and Related Chemicals.” For further information please contact one of the addresses below, or visit us at our website at www.dupontelastomers.com/viton Global Headquarters — Wilmington, DE USA Tel. +1-800-853-5515 +1-302-792-4000 Fax +1-302-792-4450 European Headquarters — Geneva Tel. +41-22-717-4000 Fax +41-22-717-4001 South & Central America Headquarters — Brazil Tel. +55-11-4166-8978 Fax +55-11-4166-8989 Japan Headquarters — Tokyo Tel. +81-3-6402-6300 Fax +81-3-6402-6301 Asia Pacific Headquarters — Singapore Tel. +65-6275-9383 Fax +65-6275-9395 The information set forth herein is furnished free of charge and is based on technical data that DuPont Performance Elastomers believes to be reliable.
