Medical composite

This material is formulated to outperform conventional metal and thermoplastic multi-lumen materials. The composite utilizes continuous fiberglass filament, not short fiber reinforcement, giving it higher mechanical properties as well as impact and dielectric characteristics. It is safe for intra-body situations and is reported to be highly resistant to nicks and cuts. Typical applications are replacements in endoscopic or laparscopic instruments such as electro cauterizing instruments.

Hydraulic piston rod

NITRO-100(R), a modified 4045 alloy steel chemistry, was formulated to meet the growing demand for steel bars to exceed a minimum yield of 75,000 psi. The new alloy is reported to exceed 100,000 psi and combines the benefits of Nitrotec, the company's former AISI 1045 steel bars, with the necessary application strength requirements.

RFM-EMI Shielding

This low-profile shielding gasket allows installation and deflection in minimal gap situations for electronic enclosure openings less than 0.08 inches. The long contact profile permits high endurance life under repeated deflections and low compression forces. It is recommended for wiping applications. Mounting can be done with a simple adhesive tape.

Polyolefin foam

These low-density packaging foams, trade named SenFlex(TM)-H, are designed for computer and anti-static packaging applications, case inserts, and automotive material handling. SenFlex-H914 is reported to be the world's first polyolefin packaging foam with a density of less than 1 pcf, whereas typical polyurethane foams can be more than twice as dense.

Rubber-covered belts

These rubber-covered belts and rollers are designed to provide static dissipative protection or non-conductivity in high-risk applications involving electronics, bulk powder processing and transfer, converting, and other sensitive operations. The belts feature a seamless, weld-free construction with a smooth, insulated surface to ground the static electric charges normally present in conveyor system transfers. The rollers can help insulate electrical circuits to treat corona discharge, or dissipate static buildup of dust particles.

Flow control components

These flow control components are custom molded and machined from Teflon(R)for applications requiring a material that is impervious to moisture, chemically inert, and can operate from -400 to 500F. Reportedly free of microvoids and microporosity, they feature seamless one-piece construction, are naturally slippery, and virtually eliminate particle shedding. They can be produced in sizes from 1/2 to 60 inches.

Photochemically etched

Better sidewall characteristics than standard etching process are the intended result with these photochemically etched parts. Stainless-steel parts fabricated by this company are resistant to organic and many inorganic chemicals, and reportedly offer corrosion and rust resistance. Parts can be fabricated in virtually any shape, in thicknesses from 0.0005 to 0.1 inch, depending on the required tolerances. Medical applications include scalpel-type knife blades and implantables.
