PVC Film

Clear marine grade PVC film is very flexible and durable. It has been specifically developed for outdoor use as windows, whether on dry land, near water or on watercraft. This PVC film can be sewn through but it is also tough enough to stand up to heavy use. The PVC compound used to make the marine grade film includes low temperature resistance, mildew inhibitors, and UV stabilizers that provide added layers of protection in direct sunlight.

APPLICATIONS

• Boats
• Seat covers
• Tables covers
• Windows
• Shields

DVANTAGES

• Low cohesion
• Mildew resistance
• UV stabilization
• -15 degree F cold crack

Flexible Vinyl Tubing

PVC tubing exhibits excellent elongation and drape. It is typically used for lower pressure applications and for OEM designs with complex tubing pathways. Several grades of flexible PVC tubing, include:

Standard: optically clear, odorless, tasteless and nontoxic; FDA compliant.

Chemical & Petrochemical Transfer: Formulated for use in the transfer of chemicals and petrochemicals including gasoline, kerosene, oils, and cutting compounds.

Nylon-Reinforced: Inner braid of nylon provides four times the working pressure of standard PVC tubing; FDA compliant.

Steel Wire-Reinforced: Kink-free, crush resistant; FDA compliant.

Bev-A-Line: High purity process tubing is lightweight, optically clear and transparent, meets standards for food, beverage, pharmaceutical, laboratory and medical device use.

Micro-Line: Mini-bore, is nontoxic, non-contaminating, and biogically stable; well suited for medical and laboratory use.

APPLICATIONS:Medical, laboratory;Food and beverage;Drainage lines;Chemical rocessing;Semiconductor processing;Environmental;Industrial.

Extrusion Foaming of DuPont™ Teflon® Fluorocarbon Resins

DuPont has developed patented technology for the compounding and processing of fluoropolymer foam resins. The foam process involves the continuous injection of a gas such as nitrogen directly into an extruder filled with molten resin. A specially designed extruder screw is typically utilized to create the polymer gas mixture with an inert nucleating package contained in the resin to help promote cell growth. Foams of up to 60% voids have been demonstrated through the use of this process.

Applications for Melt Processable Perfluorinated Resins

DuPont Teflon® FEP and PFA perfluorinated resins possess melt viscosities low enough for processing in melt extruders. Additionally, FEP and PFA are well suited for extrusion foaming while maintaining their low dielectric constant and low dissipation factors, both necessary for twisted pair and coaxial cable insulations.

Data cables are used in the transmission of electronic signals in a variety of settings and applications. The key electrical properties required for these cables include a low dielectric constant and a low dissipation factor. These properties can be enhanced by foaming the insulation. Depending on the resin used, cables having a foamed insulation allow cable miniaturization, weight reduction of the end product, and the transmission of clear high-quality electrical signals at high signal speeds. 

Foamed cables fabricated from DuPont fluoropolymer resins have become extremely popular in computer manufacturing and installation of network systems. Cables made with DuPont Teflon® FEP or PFA have low-flame and low-smoke attributes. These cables can be routed through plenums and other air handling ducts, reducing the need for the costly installation of electrical conduit.

Structure and Properties of Fluoropolymers

The discovery of PTFE by DuPont occurred in the 1930's, but at that time, the new perfluorinated resin could not be melt extruded. Further research by DuPont into the modification of the polymer architecture led to the development of a series of melt processable fluoropolymers such as FEP, PFA, and ETFE, solidifying DuPont as the world leader in fluoropolymer research. 

The ability to melt extrude these polymers, combined with such characteristics as low dielectric constant and low flammability made FEP and PFA well suited for wire and cable applications.

Industrial Grade Tubing

Industrial Grade Tubing provides extended service in a wide variety of applications, without weakening or cracking, and can withstand extreme temperatures from -75°F to 275°F.

Typical applications for Industrial Grade Tubing include caustic dispensing, wastewater sampling, soap and disinfectant dispensing, transferring printing ink, glass and window washing systems and more.

Industrial Grade Vinyl tubing offers high performance at a low cost. This industrial grade is flexible and offers a broad range of chemical resistance, but is not recommended for use with foods, beverages, or drugs. For prolonged exposure this material is available in extruded black since it naturally resists bacteria growth.

PTFE + MICA MINERAL FILLED

PTFE (PolyTetraFluoroEthylene) is a fluorocarbon-based polymer also known throughout the industry as Dupont’s brand name Teflon®. Several other manufacturers make their own brands of PTFE which can often be used as substitute material. This fluoroplastic family offers plastics with high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation, and “slipperiness.”

PTFE filled with 5% to 10% mica provides a unique blend of strength and dimensional stability along with an excellent wear enhancing additive technology. This product provides excellent wear and stability in addition to FDA compliance.

Fluorosint® is a proprietary mixture in which synthetically manufactured mica is chemically linked to PTFE. This bonding results in properties not normally attainable in reinforced PTFE. Fluorosint® grades offer an excellent combination of low frictional properties, dimensional stability, excellent chemical resistance, and continuous use temperature of 500°F (260°C). Compared with PTFE, it has higher load carrying capability, 1/9 of the deformation under load, and a lower coefficient of thermal expansion.

FLUOROSINT GRADES
Fluorosint® 500 has nine times greater resistance to deformation under load than unfilled PTFE. Its coefficient of linear thermal expansion (CLTE) approaches the expansion rate of aluminum and is 1/5 that of PTFE — often eliminating fit and clearance problems. It is 1/3 harder than PTFE, has better wear characteristics, and maintains low frictional properties. Fluorosint ® 500 is also non-abrasive to most mating materials.

Fluorosint® 207’s unmatched dimensional stability, excellent creep resistance and white color uniquely position this material to serve FDA regulated applications. It is non-permeable in steam and complies with FDA regulation 21 CFR 175.300. It’s relative wear rate is 1/20 the rate of PTFE below 300°F (150°C). The combination of good mechanical performance and its inherent outstanding chemical and hydrolysis resistance, Fluorosint® 207 opens numerous application possibilities in food, pharmaceutical, and medical industries.

• Bearings, bushings

ADVANTAGES

• Good wear resistance
• Excellent chemical and hydrolysis resistance
• Good chemical properties
