A. Schulman TPP20AN05BK 20% Talc Filled, Heat Stabilized, Copolymer Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene with 20% Talc Filler

Material Notes: 20% Talc Filled, Heat Stabilized, Copolymer Polypropylene

Description: Precolored black

Applications: Primary end use is for parts requiring stiffness and dimensional stability.

Specifications: Meets/exceeds DaimlerChrysler Engineering Standard MS-DB532 Type B.

Comments:
Tensile Retention: 26.1 hrs.; (240 hrs. @ 150°C); MS-DB532 Type B Specification: 22.9 Min.; ASTM D638
Mineral Content: 20.2%; MS-DB532 Type B Specification: 18.0-22.0; ASTM D2584
Material Pre-dry: Normally it is not necessary to pre-dry this material. However, if conditions dictate drying to optimize material properties and part appearance then dry in a desiccant dryer at 180°F for 2-3 hours or 160°F for >4 hours.
Manifolds: Maintain manifolds, runners and tips 10 to 20°F above the front one temperature to allow easier filling. (Gate drool is best eliminated using screw decompression rather than reducing tip temperature.)
Back Pressure (Range): 20-50 psi. Injection Speed: medium to fast. Screw Speed: medium. Injection Pressure: Adjust to just above a short shot. Injection Time: Adjust to just above a short shot. Cushion (Range): 0.2-0.5 in. Nozzle Type: Free flowing/Standard.
Some conditions may have to be altered to obtain acceptable parts. Please do not run too cold, molded in stress and rough surface may become a problem. If you must run below melt or temperatures recommended for dimensional precision you may compromise impact and esthetics. Retest parts to confirm performance.
