*Tortex and Delrex by Jim Dunlop and D'Andrea Picks are trademark names for Dupont's Delrin which is acetal homopolymer. *Steve Clayton uses acetal copolymer for their line of Acetal picks. Both acetal materials are very similar.
Description: yellow Color Acetal 8"X12" (0.50mm thick) enough for about 56 to 72 picks depending how conservative you are when punching (SEE NOTE BELOW). We sized this so it would ship easier with punch orders and to keep shipping rates correct. This is a versatile material with good tone.
Note that there will be processing blemishes on these from handling and cutting the sheets down like small blemishes and edge pops from the cutting blades. If you need a blemish free piece for some reason please email me and I will try to find what you need. For making guitar picks it really doesn't matter.
IF YOU ARE ORDERING THESE SHEETS WITH A PUNCH WE WILL HAVE TO CUT THE PLASTIC SHEETING INTO FOUR STRIPS SO IT WILL FIT IN THE BOX. THIS MAKES IT EASIER TO PUNCH THE PICKS BUT THIS WILL REDUCE THE AMOUNT OF POSSIBLE PICKS TO BE PUNCHED DOWN TO 72 OR SO PER SHEET. IF YOU ARE ORDERING JUST THE SHEETS WE WILL SHIP THE ENTIRE SHEET UNCUT WHICH WILL ALLOW FOR MORE PICKS IF YOU ARE CONSERVATIVE WHEN PUNCHING.
GENERAL INFORMATION REGARDING ALL PICK MATERIALS:
Most common picks are made out of various types of plastic. Most popular plastics include:
Celluloid. Historically, this was the first plastic ever used to produce picks, and it is still of some use today, especially for guitarists aiming for vintage tone. Occasionally, guitarists who smoke have accidentally discovered the extremely flammable nature of this material.
Nylon. Popular material, has a smooth and slick surface, so most manufacturers add a high-friction coating to nylon picks to make them easier to grip. Nylon is flexible and can be produced in very thin sheets. Most thin and extra-thin picks are made out of nylon. However, nylon loses its flexibility after 1–2 months of extensive use, becomes fragile and breaks, so guitarists that use thin nylon picks should have several spare picks just in case.
Tortex / Delrex. By Jim Dunlop and D'Andrea Picks respectively. Brand names for DuPont Delrin which is specially treated to have a matte, opaque surface, surprisingly easy to grip even with sweaty fingers.
Acetal. Acetal is a class of plastics, which is divided into two groups. The copolymer group, was first introduced by McAndrew Hoechst Celanese Corporation in 1960. Steve Clayton uses this branch for their line of Acetal picks. DuPont's (Wilmington, DE) Delrin developed and patented acetal homopolymer. Delrin is a Dupont trade mark/name. Dupont homopolymer acetal, is slightly harder, and stiffer than the copolymer branch. Both acetals have a matte surface for grip, and are highly durable.
Ultem. This space age plastic has the highest stiffness of all plastic picks. Produces a brighter tone. Introduced by Steve Clayton,Inc., the material is additionally popular among mandolin players.
Lexan. Glossy, glass-like, very hard surface, though it wears out relatively fast. Barely bends at all and it's commonly used only for thick and extra-thick picks (> 1 mm). Usually has a high-friction grip coating. Best known example of Lexan picks are Jim Dunlop Stubby series.
Modern plastics can be ranged this way from the easiest to bend to the hardest: Nylon, Acetal, Delrin (Tortex/Delrex), Lexan, Ultem. This means that the same medium (for example, 0.70–0.80 mm) pick would be fairly flexible if made out of nylon and very solid if made out of Ultem.
