TECAPRO® MT Rod

TECAPRO® MT is a medical grade polypropylene supplied as extruded stock shapes with low residual stress, so machined parts with uneven wall sections stay flat and in tolerance. Polypropylene brings the broadest acid and caustic resistance of any commodity thermoplastic along with near-zero moisture pickup, and this grade is specifically formulated to resist hydrolysis and superheated steam. Tensile strength at yield is 4,918 psi with a 210,000 psi flexural modulus and 50 percent elongation at break. Long-term service temperature is 212°F with 284°F intermittent, heat deflection temperature is 187°F at 264 psi, and the melting point is 325°F.

It is used for autoclavable sterilization holders and trays, fluid handling and labware fixtures, filter and housing components, pharmaceutical process parts and food contact equipment. TECAPRO® MT is tested to USP Class VI and ISO 10993 and is FDA compliant, and it is autoclavable as well as compatible with gamma and ethylene oxide sterilization. Machine it with sharp, highly polished tooling and keep chips clear, since the low melting point makes it prone to gumming at high surface speeds. It is the softest and least rigid material in this group, so it is not a load-bearing structural choice.
