This extrusion guide offers technical processing tips for working with Alcryn melt-processible rubber (MPR), an elastomer that provides the ergonomic and performance qualities of rubber with superior oil, heat and weather resistance. The brochure features information on rheology; material handling and safety; processing by different types of extrusion and co-extrusion equipment; and processing parameters.
These chemical formulations aid in brazing and heat-treating operations by preventing unwanted filler-metal flow and the accidental fusing together of parts. Technical Data Sheet 2.2.1 provides details on ten types and grades of stop-off materials in the Nicrobraz line, as well as recommended uses and applications.
Functional materials, such as fatty nitrogen chemicals, fatty alcohols and derivatives, fatty acid derivatives, odor absorbers, organomodified siloxanes and antifoams, are featured in this 36-page catalog. Each section begins with an introduction to the product line and its basic chemistry, then presents a complete list of products in that category.
This brochure explains that semi-crystalline polyaryletherketone (PEEK) can be used as a matrix for thermoplastic composite prepregs made of carbon, glass or aramid continuous fibers. It highlights the polymer’s ability to withstand continuous operating temperatures of up to 260°C in low-stress applications and 120°C wet in aerospace structural applications. It discusses the stages of composite forming, including heating, pressurization and cooling, and it details the compatibility of PEEK-based composites with a range of rapid, automated and economical fabrication processes.
A 100%-solids epoxy novolac coating, ARL 6000 provides excellent protection against severe chemical attack. Easily applied by brush, roller or squeegee, its low-viscosity formulation helps ensure complete surface contact and excellent adhesion to metal and concrete surfaces. It can be used to protect floors under chemical or acid storage tanks or pumps, to line concrete or metal secondary containment areas, to line tanks handling concentrated acids and other chemicals, and to protect various other substrates that are prone to chemical attack.
XTJ-590 is an epoxy hardener that provides fast curing at low temperatures while imparting good mechanical properties to the system. It is a reactive polyether diamine of low molecular weight, and can be used in epoxy adhesives, hot melt adhesives, construction chemicals, composites, coatings, polyamide elastomers and epoxy curatives. Its cure speed is approximately four times faster than the firm’s popular JEFFAMINE D-230 product.
Ecovio LBX 8145 is the first of a family of materials to be made with Ecoflex (a completely biodegradable plastic based on petrochemicals) and renewable raw materials. It contains 45% by weight polylactic acid (PLA), which is made from corn. Its first application will be flexible films that can be used to make plastic shopping bags.The Ecovio plastics will be usable directly without further modification to extrude biodegradable films.
Dubbed Viton GF and Viton ETP, these new fluoroelastomers have been developed with advanced polymer architecture (APA) technology that provides much better chemical resistance than Viton A, which has been the backbone of the Viton line until now. Laboratory tests have shown that APA provides improved resistance to steam and some cleaning fluids used in food and pharmaceutical processes compared to older diamine- or bisphenol-cured dipolymer fluoroelastomers. The new materials are being used in gaskets, O-rings and custom-molded parts for critical sealing applications.
P-80 Emulsion IFC and P-80 THIX IFC temporary rubber lubricants comply with FDA standards for use in incidental food-contact applications. A thin film of P-80 IFC reduces the force needed to install a tight-fitting rubber part; once it dries, the normal non-slip condition of the rubber returns. Both lubricants are easily applied by manual or automatic methods. The P-80 products do not contain petroleum distillates, so they will not dry out or harden rubber. They have low volatile organic compound (VOC) content, are non-toxic, non-flammable, and have a near-neutral pH.
Based on copolymer polyacetal (POM), the PRE-ELEC 12-000 compounds offer the excellent chemical resistance, toughness and low coefficient of friction of polyacetal while providing electrostatic dissipation (ESD) protection. The compounds can be colored for color-coding, and are available with or without fiberglass reinforcement.
