click to resize photo TecaMax SRP is produced from Primospire (formerly Parmax ) self-reinforcing polyphenylene resin, claimed to be the world's strongest and stiffest unfilled thermoplastic. Developed by Mississippi Polymer Technologies (acquired by Solvay Advanced Polymers in 2006), this material is available in molded stock shapes (sheet and rod) produced only by Ensinger.

TecaMax (Primospire) SRP's exhibit extraordinary mechanical properties, corrosion and resistance and cryogenic properties. Its hardness and scratch resistance are comparable to aluminum, carbon steel, stainless steel and magnesium It also can be machined with carbide tips without stickiness, which is comparable to metal machining methods.

TecaMax (PrimoSpire) SRP also has exceptional flame retardance without a flame-retardant additive, as it is self-extinguishing with no smoke, no dripping and minimal effect on the polymer.

At this time, TecaMax SRP is only available in LIMITED AMOUNTS
in sheet/plate forms only. The manufacturer is in the process of
re-evaluating the manufacturability of TecaMax SRP material.
Please contact us for more details on availability of TecaMax
before specifying this complex material for your application.

• Ultra high strength-to-weight ratio   • High Modulus (stiffness) & Low CLTE   • Exceptional abrasion resistance   • Unaffected by moisture or chemical exposure   • Inherent flame resistance   • Highest surface hardness of any thermoplastic   • Isotropic mechanical properties
