Polyolefins Spotlight

Polyethylene (PE) and Polypropylene (PP) are two of the largest volume thermoplastics used today and are available in a wide range of grades and formulations. PE is commonly grouped into Low, Medium and High density formulations’ and PP is available in homopolymer and copolymer formulations. The various formulations of these popular polyolefins impart a wide range of properties making them appropriate for countless applications. Generally speaking, polyolefins are tough, chemical resistant and offer good electrical properties with a low coefficient of friction and moisture absorption. They are relatively lightweight and easy to fabricate. Polyolefins find proven applications in a wide range of markets from medical and chemical to toys and sporting goods and oil and gas to food processing and marine. Following is an overview of a variety of materials from sheet, rod and tube to massive shapes and profiles.

Improved Medical Grade Polypropylene Line

Ensinger, Inc. has set the standard for quality and innovation with their line of products developed specifically for medical applications. Tops among them is the TECAPRO™ MT line, a polypropylene based product with exceptionally low residual stress characteristics that facilitate the fabrication of dimensionally stable parts consisting of varying cross sections. The material can withstand repeated hot steam sterilization procedures without deforming and has a high resistance to detergents and disinfectants. This has historically made it an excellent material choice for surgical caddies and instrument handles.

Until now however, users who wanted to design parts in colors other than white had little choice because of those colors’ inability to receive laser etched markings of significant contrast to render the markings readable. Ensinger has now developed a black TECAPRO MT that contains an additive that enhances the material’s ability to receive laser etching. Markings laser etched into this new black material are so clear, they appear to be silk-screened. Engineers and designers alike will be drawn to this material for its versatility, and its stability.

Stock Tank Couplings

Fabricated and molded tank manufacturers are finding there is no longer a need for trips to a machine shop because economical heavy-duty tank couplings, designed for their application, are now available. IPW tank couplings are easy to install and are sized to fit standard hole saw dimensions. They have a shoulder that gauges installation depth and provides for guaranteed square installations on flat surfaces. The shoulder also provides better weld strength and easy installation on round tanks. The shoulder and the low profile design, combined with thick cross sections, practically eliminate couplings shearing off from side impact. The thick cross-sections prevent the splitting commonly seen with FPT threaded couplings. IPW features sizes 1/2" through 4" from stock in natural HDPE, black HDPE, natural PP and black Type II (copolymer) PP. Eurogray PP, PVDF, PVC and CPVC materials and sizes 1/8" to 24" are now available on request. IPW provides full couplings when interior piping is needed and for vertical installations on domed tanks.

Boosting Sales Through Innovation

Every plastics distributor and fabricator knows innovation is the key to growth. Sometimes a new product simply provides an “excuse” to reach out to an old contact. But sometimes a new product can open up entire categories of prospects and lucrative new business opportunities. King MicroShield® by King Plastic Corporation is just such an innovation. King MicroShield is a new kind of anti-microbial now available in many of King Plastic’s sheet products for medical, laboratory and institutional applications. It helps products stay cleaner between cleanings and inhibits the growth of productdamaging microorganisms, including bacteria, algae and fungi on the surface. Microbe cell walls that come into contact with the material are physically destroyed on contact, without creating opportunities for adaptive or resistant strains to form. It is bonded at the atomic level throughout the sheet, so it retains its effectiveness for the life of the product and will not leach out and harm the environment.

King Plastic Corporation has a history of innovation spanning more than four decades. The North Port, Florida-based company manufactures dozens of varieties of polymer sheets, slabs and massive shapes used in a broad range of applications. These include waterproof cabinetry and casegoods (commercial and residential), restroom partitions, pipe-grade and chemical-resistant fabrications, cutting boards, signage, neutron shielding and, of course, boat parts.
