Provide a 0.003” to 0.005” interference when using plastic inserts or substrates, to take into account shrinkage, sinks and tolerances. 5. In the selection of TPE hardness the thickness should be taken into account to get the right feel and esthetics on the product.

This ensures that we have leadership accountability to advancing our D&I strategy. Non-toxic and heavy-metal-free ingredients and biodegradable carrier resins. Also, our CESA™ Additive Masterbatches are utilized for solar back sheets to enhance the halogen-free mono material structure and protect against voltage breakdowns.

Follow up by purging machine with general purpose PP • Residence time should not exceed 5 minutes for Maxxam FR products • General ventilation is suggested Shut Down • Purge the equipment with a general purpose PP • All tooling and equipment must be free of any residual Maxxam FR upon shut down • Continue generating parts made from the natural PP until clear • Wipe down tool steel with mold cleaner • When using a hot runner system, care must be taken to remove residual product from the manifold MOLD DESIGN RECOMMENDATIONS Cold Slug Wells • Place cold slug wells at the base of the sprue to capture the cold material first emerging from the nozzle • Place cold slug wells at every 90° bend in the runner system • Well depths approximately 2–3 times the diameter of the runner provide best results Draft Angle • Draft angle should be 1/2°–1° per side.
