POROUS PTFE RODS, TUBES & SHEETS

PTFE Porous Rods, Tubes & Sheets are excellent for use in extreme heat up to +500° F (260° C) and resistant to a low end temperature of -328° (-200° C).  PTFE is used in applications where other plastics break down due to their inability to be resistant to chemicals and heat.  It is said that PTFE exhibits a combination of mechanical, electrical, chemical temperature and friction resistant properties unmatched by any other substrate.  It is a non-reactive, high molecular weight fluoropolymer compound used in aerospace, pharmaceutical, chemical and petrochemical fields.

BLUNT TIP PIPETTING NEEDLES

Our 2″, 4″ & 6″ long laboratory blunt tip pipetting needles are available in gauges 5 through 30. Needle lengths of 12″ long are available in 8 through 27 gauge. All needles are made of 304 stainless steel and fitted with American standard short female luer hubs of nickel-plated brass. The short hub reduces the dead volume inherent in all American standard luer hubs. Needles are supplied with a 90-degree blunt tip.

SOLID ALUMINUM TEST TUBE RACKS

SCI’s custom manufactured heavyweight solid aluminum test tube racks are hard anodized coated. They are perfect for hot & cold water, and for ice baths. They will not float around or tip over while submerged in circulating liquids. They are ideal in sub-zero applications with liquid nitrogen. The small holes in BB208 and BB209 allow for drainage and circulation. At 1 1/2 pounds these solid aluminum blocks hold temperatures very accurately. The block dimensions are 5 3/4″ x 3″ x 1 1/4″ thick. BB216 measures 9″ x 3 3/4″ x 1 1/4″ Thick and weighs 2.4 pounds. Temperature resistant from -100°F to +300°F.

POROUS RODS & TUBES

UHMW Porous Rods - Tubes

Our Porous Rods & Tubes are available in hydrophobic and hydrophilic formulations to accommodate your needs.  Porous Rods are used in wicking and venting applications. Through capillary action, our porous plastic wicks are capable of drawing aqueous and non-aqueous fluids out of a reservoir for dispersion through direct absorption or evaporation.  Our Porous Tubes are made from UHMW (ultra high molecular weight) polyethylene, PE co-polymers, or polypropylene with an average pore size from 5-200 microns. They are strong at various wall thicknesses with the ability to withstand high levels of pressure. The material is resistant to many chemicals and a wide range of temperatures.

FEP HEAT SHRINK TUBING & TUBES

FEP Heat Shrink Tubes & Tubing

SCI fluorinated ethylene propylene (FEP) heat shrink tubing & tubes are preferred for their lower shrink temperature, greater flexibility, optical clarity & lower costs.  The clarity of FEP is ideal for medical applications where visual inspection of jacketed components is required.  This FEP jacket protects parts from high heat, chemicals, abrasion and moisture.  This tubing is supplied in the expanded state and when heat of 420°F (215°C) it will shrink by roughly 15-20% on small tubing diameters and 20-25% on the larger diameter tubes.  This is referred to as 1.3:1 ratio.

FEP FILM

FEP (Fluorinated Ethylene Propylene) holds its shape under stress and high temperatures better than PTFE.  FEP has a temperature range of -320º F. to +400º F, is FDA compliant, and meets UL 94V0 for flammability.  Ideal applications for this fluoropolymer are 3D printers, tank and pump linings, UV applications, and gasketing and mold release.  These materials offer excellent electrical insulation, chemical resistance, weatherability and low permeability.  Manufactured in the United States.  When using this FEP Film with 3D printers we strongly recommend using at least 5 MIL or 10 MIL thick film.

EXPANDED PTFE SPONGE SOFT GASKET

EPTFE Expanded PTFE Sponge Soft Gasket

EPTFE is an expanded 100% virgin PTFE resin. The finished expanded PTFE exhibits characteristics significantly different than standard PTFE sheet. The EPTFE is softer and more flexible and therefore it conforms much easier to rough and irregular surfaces. This softer material is more compressible and has a lower cold flow rate with minimal creep. This material complies with FDA regulations for food contact and EU1935/2004. It is compatible with aggressive chemicals from a range of 0 to 14 PH, except molten alkali metals and elemental fluorine. This clean and non-toxic gasket material is used in the food and drug, petro chemical and pulp and paper industry as well as the distilling and marine industry. It resists temperatures from -450° F to +500° F.

PTFE GLASS FABRIC

PTFE Glass Fabric - Use

PTFE resins are used in both our standard & premium grades of fabric. They will withstand -100°F to +500°F. The difference between the standard and premium grade is the amount of PTFE resins that is applied to the woven fabric. The greater the thickness of PTFE the better the chemical resistance and higher electrical strength. The texture of the premium is also smoother and provides a more lubricated surface. The standard grade feels somewhat porous and allows better drainage. Manufactured in the United States.
