product inquiry
TECAFORM AD CAL natural is an unfilled homopolymer acetal material, processed into thin Delrin sheets and rolls by means of calendering. These Delrin acetal sheets are available as Delrin sheet stock and are suitable for a wide range of applications, including Delrin sheets for guitar picks. In general, the material has similar properties to TECAFORM AD natural. TECAFORM AD CAL natural is also processed into punched Delrin washers, such as Delrin flat washers or even Delrin thrust washers, offering precise solutions for demanding tasks. Additionally, Delrin plastic sheets and Delrin strips are available for custom orders, making it easy to buy Delrin sheets tailored to specific needs.
