LONG FIBER COMPOUNDS MOLDING GUIDELINES: Equipment Considerations
A general purpose screw that utilizes a typical three-zone style is best for processing Long Fiber Compounds. The screw has three sections: feed, compression, and metering. Metering should be done with an L/D ratio of 16:1 to 22:1, with a low compression ratio of 2:1 to 2.5:1.
Long Fiber Compounds Molding Guidelines
When processed properly, Long Fiber Compounds retain their fiber length during molding. Correct processing is critical to maintaining high-quality parts; breaking the fibers during processing can result in sharply reduced material properties.
Overmolding Design Considerations
The required adhesion is dependent on the end-use application and environment. Not all overmold grades bond to all substrates. The substrate type determines which RTP Company TPE overmolding grade must be used to achieve the best bond. The end-use environment also influences which grade to select. The expected service life of the product should be considered when establishing adhesion requirements. Initial material selection is the first step.
Thermoplastic Elastomer Molding Guidelines
Obtaining rubber like performance with the processing ease of injection molding is the primary benefit of TPEs. Improved cycle times and reduced scrap rates esult and allow for improved part economics.

Molding Technology: TIPS TO IMPROVE SURFACE CONDUCTIVITY
Compounds with Conductive Fillers
The parts may look beautiful but not be functional in static dissipative applications. The following processing conditions are important to successfully molding good, conductive parts.
Compounds with Conductive Fibers
Conductive materials based on carbon fiber typically require opposite molding conditions from conductive fillers.
