PycnoPlast - Model Pycno 495 -Fire Retardant Masterbatch

SHARE

Fields of application Injection moulded, or moulded articles (> 1,5 mm thickness) produced via Direct LFT processes. Examples Moulding parts such a under body panels, door modules, industrial parts, appliances, etc. Mode of action PYCNO 495 provides excellent flame retardancy to thick PP products and contains an extra stabilization package for special long service life requirements. The flame retardant is active in the solid phase of the polymeric system. It forms a stable char, which inhibits the fire propagation.

Characteristics Composition PP copolymer based flame-retardant compound / masterbatch depending on the FR performance to be achieved.
Appearance Off-white granules
Storage and handling 12 months from delivery in original packaging. Keep in cool, dry and well-ventilated area. Storage in closed bags, product is hygroscopic.
Temperature stability The product may be suitable for processing temperatures up to 250-260°C. The processing temperature should not exceed 270 °C. Also the processing equipment should be flushed with standard non-flame retardant PP before stopping the line.
Dosing equipment For maximum flame retardant performance (UL 94 V0) in PP copolymer PYCNO 495 should be used at 80 % combined with 20% PP copol. For less demanding requirements the product can be further diluted with regular PP, for instance 70% PYCNO 495 + 30% PP or in a 60:40 composition.
Processing equipment All injection moulding machines and extrusion lines
