Nathan Posted July 30, 2004 Report Share Posted July 30, 2004 Hi Guys, I don't get down here very often....Does anyone know if anyone makes crawtubes similiar to the Mad man versions out of the new cyber-flex material?...I need them for a new hybrid crankbait I'm working on....Thanks..Nathan Quote Link to comment Share on other sites More sharing options...
jigmeister Posted July 31, 2004 Report Share Posted July 31, 2004 I think the only two mad man types out there are the mad man and the one made by yum . Quote Link to comment Share on other sites More sharing options...
Tm Customs Posted July 31, 2004 Report Share Posted July 31, 2004 Nathan cyberflex doesnt make and craws like madman, and I don't think anyone else is because the flex plastics is very hard to work with. Tm Quote Link to comment Share on other sites More sharing options...
BigZ Posted July 31, 2004 Report Share Posted July 31, 2004 Storm makes a nice craw tube that is not plastisol They are made of PVC, I know they are exceedingly soft, and they are supposed to be "twice as durable" as a regular plastic bait. May be worth a shot. I see a lot of that stuff on eBay cheap. Hope it helps. Quote Link to comment Share on other sites More sharing options...
clemmy Posted July 31, 2004 Report Share Posted July 31, 2004 Z-- I believe plastisol IS PVC... Quote Link to comment Share on other sites More sharing options...
alsworms Posted July 31, 2004 Report Share Posted July 31, 2004 PVC is made of 3 compounds.....Poly Vinyl Chloride; none of which are plastisols. PVC is a polymer used as a plastic when mixed together; same type of material that our worm bags are made of, only a softer grade of course. I only know because I spent lots of wasted time trying to figure out how to make my own plastisol. Here's an incredibly boring link on PVC....... http://www.psrc.usm.edu/macrog/pvc.htm Quote Link to comment Share on other sites More sharing options...
clemmy Posted July 31, 2004 Report Share Posted July 31, 2004 I'm not a chemist, so I can't really argue, what I know is from researching online, from what I can tell, pvc is a polymer, plastisol is pvc mixed with a plasticizer (what we call "softener"), and most plasic bags are actually polypropalene... From some google searches for plastisol pvc, plastisol definition, etc:: "Plastisol: A balanced dispersion of polyvinyl chloride resins in liquid plasticizers with many different additives that will provide unique and specific print properties. Plastisol is a thermoplastic that requires a specific amount of heat and time for fusion (complete drying). Additives can produce special effects, limit dye-migration, reduce fusion temperature requirements, and countless other uses. Every plastisol will have unique chemical compositions to provide exact print performance." "Plastisol (extended definition) Modified PVC or PMA dispersion which requires heat to harden. The resultant joints are often resilient and tough. " "Plastisol is a vinyl compound that is liquid at room temperature and will keep for years. When heated it fuses into ordinary vinyl never to liquefy again. Plastisols can be compounded to produce vinyl that meets almost any durometer (hardness), clarity, color, electrical, chemical, and weather specs. Surface appearance can go from shiny to matte. It can also be compounded to meet many standards, including FDA food contact, Non-Toxic, USP Class VI, UL, & MIL-P-20689. " "Vinyl plastisols and powders are dispersions of special fine-particle PVC resin and additives in a plasticizing liquid used for processes such as dip coating, slush molding, rotational molding and fluidized bed coating." From an In-Fisherman article on Gulp by Berkley: "Prochnow says that the Gulp! line is made of water-based polymers instead of plastisol. "Water can permeate the entire bait, constantly releasing scents and flavors to attract fish. Tests show that active ingredients are released about 400 times faster than with standard flavored baits constructed of PVC plastic." "Plastisols General InformationA PLASTISOL IS A GENERIC INDUSTRY TERM WHICH REFERS TO A FLUID DISPERSION OF A PVC (POLYVINYL CHLORIDE) RESIN. THEY HAVE BECOME A FAMILIAR MATERIAL TO THOUSANDS OF MANUFACTURERS MAKING SUCH PRODUCTS AS OVERSHOES, UPHOLSTERY FABRICS, TABLE CLOTHS, SHOWER CURTAINS, FOAM CUSHIONING, COATED PLATING RACKS, SMALL SOFT BODY FISHING LURES, SUPPORTED AND UNSUPPORTED GLOVES, AND TEXTILE SCREEN PRINTING INKS. THE ORIGINAL PATENT RELATING TO PLASTISOLS WAS ISSUED TO B F GOODRICH CHEMICAL COMPANY IN THE EARLY 1940'S WITH PATENT 2,188,396. IN 1947, GOODRICH INTRODUCED, COMMERCIALLY, THE FIRST VINYL RESIN DESIGNED FOR MAKING PLASTISOLS. " As I said, I'm no chemist, but the plastic companies seem to think plastisol is made from pvc....

clemmy Posted July 31, 2004 Report Share Posted July 31, 2004 :oops: 2 more things; Sorry about the caps, I just cut and pasted from the sites, and some were in caps... Secondly, apologies to Nathan, who is still looking for his cyberflex answer I think... Craig Quote Link to comment Share on other sites More sharing options...
BigZ Posted July 31, 2004 Report Share Posted July 31, 2004 The storm plastic is not typical lure plastisol, it has an "added blocking agent" whatever the hell that is. My point wasn't an exact chemical specification, but that their craw tubes might be an alternative to the cyberflexxx stuff for Nathan. I used their swimbaits last summer for halibut and lings in shallow water and they hold up extremely well (3 or 4 fish per, and we're talking evil teeth on those fish).

alsworms Posted July 31, 2004 Report Share Posted July 31, 2004 This site is really a kick. Where else can you go from questions about crawdads to talking about the chemical breakdown of plastisol in one thread?? Man I can really get off the subject sometimes..........

Nathan Posted August 2, 2004 Author Report Share Posted August 2, 2004 Thanks for the help guys...And Chris,your right....where else can you get off on topics like this with a single question......it's fantastic!!!!..Thanks again guys...Nathan Quote Link to comment Share on other sites More sharing options...
