    Default Question about SL8 polymer

    I know that its a Nylon 6.6 base but I'm wondering what the filler is and if anyone knows what the plastic is called?

    Also does anyone know how the weight of the Nylon 6.6 used in the SL8/G36 compaires to aluminum?

    someone on here posted that before. Not sure where it is. I think they said it was carbon fiber re-enforced nylon 66. Tbostic or chopstix kid may know. They do a bunch of nice work on the SL8s. Shoot them a PM

    30% glass filled nylon 6-6 is what I have been told in the past.

    Nylon 66 is 1.14 grams per cubic cm. Aluminum is around 2.7 g/cm3 depending on exact alloy.

    And Nylon 6/6 is what the plastic is called, it is a trademarked name by Dupont, but it was created in 1939 so pretty much anybody can make it now. Nylon is generically called a polyamide polymer, Nylon 6/6 is just one of several polyamides.

    Wow only 30%? I'm kinda surprised I would have thought it would be closer to 60%.

    Any of you guys know if I could get blocks of nylon 6-6 to machine prototypes etc?

    Cheers,

    Sean

    Absolutely. Do you need glass filled, or just solid nylon? I'd go with pure nylon for prototypes, the glass filled stuff is more expensive, and really hard on tooling. You can use standard HSS on nylon, it's carbide only for glass reinforced. 12x12x2" nylon will run about $140. 12x24x2" about $260. Here's just one source: http://www.indplastic.com/index.cfm?...31&product=229

    Google for plastics supply and you'll get a ton of suppliers
