- HDPE (high-density polyethylene). - Thicker wall than competitors; less flex, which reduces paint chipping/flakeoff. - Double shock cord/chute eyelets, which make them much stronger.
- Ridges on shoulder that can be easily sanded to achieve perfect fit; shoulder also provides better sealing, like piston rings in an engine.
All PML plastic nosecones are 4.2:1 length/diameter ratio, with a true ogive shape. Sizes indicate the internal diameter of the
tubing they fit.
Suggestion - Polyethylene is notorious for being difficult for adhesives to adhere to. First of all, wash the nosecone in very hot, soapy water and rinse. This will help remove any mold release compound from manufacturing. Secondly, sand all surfaces to be bonded with 120 grit sandpaper. - Fill imperfections in plastic nose cones with Squadron Green or White putty, automotive spot putty, etc. - Neither acetone nor MEK causes any problem on plastic NCs (used in moderation and for short-term contact with the plastic, of course). - If you need to add noseweight for CG/CP adjustments, we recommend sand held in place by PML Two-Part Expanding Foam (sold on the Adhesives section of this webstore).
