Interplastic offering fire-retardant resins
Interplastic Corp. is offering a new line of fire-retardant vinyl ester resins for unsaturated polyester applications.
The new Corve-brand products are aimed at corrosion, transportation, construction and consumer goods. Four products are currently available. One version resists chemicals for ducts and similar applications. Another is high strength for tanks, fittings and marine mufflers. A third type provides a laminate that is clear and easy to inspect. The final version contains antimony pentoxide to enhance fire resistance. It is easily applied with spray-up, hand lay-up and filament winding, according to St. Paul, Minn.-based Interplastic.

Chemline PU coating boasts fire resistance
Chemline Inc. has introduced a fire-resistant polyurethane coating suited to a range of plastics.
Chemthane 7001FR can coat foam, expanded polystyrene and other lightweight molded architectural products. The hard coating has features that reduce labor costs. Users don't have to sand the PU to get a smooth surface, according to the St. Louis-based company. The product is designed to flow out better during the initial cure-to-touch time. Impact resistance and tensile strength have been improved.
Chemline claims its coating applied to lightweight plastics cuts production time compared with making architectural elements and wainscoting using fiberglass-based techniques.

CVC resin resistant to high temperatures
CVC Thermoset Specialties has unveiled a new thermoset resin aimed at high-temperature electrical applications.
Epalloy 8370 A85 is an epoxy phenol novalac resin supplied in an 85 percent concentration in acetone. Its high temperature resistance addresses the shrinking of electrical devices, causing them to operate at higher performance levels.
Applications for the new resin include prepreg, filament winding, printed circuit boards and encapsulation. It is compatible with standard curing agents and most other resins and resin modifiers, according to the Moorestown, N.J., firm.

Pump is adaptable to several processes
Novosystems Farben & Additive GmbH of Seevetal, Germany, said its WB4000 dosing pump is designed to meter out liquid colorant for plastics processing.
It can be fitted with three different pump heads, for injection molding, extrusion or polyurethane processing. A new progressive cavity pump head can be used either for very large capacity, such as coloring for extrusion processes, or for large amounts of color, at high levels of accuracy.
Novosystems also makes the liquid colors.

AGY fiber suitable for use in implants
AGY Holding Corp. has developed a high-performance glass fiber for biomaterial composites used in dental and medical implants.
The new fiber, HPB, is suitable for implant applications of duration of more than 30 days. It is compatible with a range of thermoplastics, including polyetherether ketone, polyether imide and polyphenylene sulfide.
HPB has 40 percent higher tensile strength and 20 percent greater tensile modulus than ordinary E-glass fibers, according to the Aiken, S.C., firm. Applications include orthodontics and dental implants and potentially, orthopedics.

B&H to supply dies to Brazil hose maker
B&H Tool Co., which makes plastic extrusion tooling, has been selected to supply crosshead dies, in-line dies and related tooling for MFX do Brasil in Salvador, Brazil.
MFX is a leading producer of high-pressure and high-resistance thermoplastic hose for marine, industrial and consumer applications. B&H will provide crossheads for the company's “umbilical” extrusion lines, used to make complex hose and cable assemblies that provide electrical and hydraulic power to offshore oil and gas platforms. The hoses are extruded from nylon or polyethylene.
B&H Tool is based in San Marcos, Calif.

BayOne urethane foam is optimal for seating
BayOne Urethane Systems LLC has a new moldable, flexible urethane foam that can be made at low densities.
Bayfit 500 can be molded over a range of hardnesses and in densities as low as 2.7 pounds per cubic foot. Conventional, competing foams can be made at densities of 3.1 to 3.8 pcf, according to the St. Louis, Mo., company.
BayOne developed the foam mainly for seating and cushioning. Its low density allows a 15 to 20 percent reduction in material usage. The two-component foam is water-blown and formulated with 100 percent diphenylmethane diisocyanate. Properties are similar to standard MDI-based flexible foam products.

Huber latest resins are flame retardant
Huber Engineered Materials has launched three alumina trihydrate grades for flame retardance and filler properties in thermoset resins.
MoldX A100 is a flame retardant capable of very high loading levels — up to 400 parts per hundred resin, according to the Atlanta, Ga., company. MoldX C2000, a combination of ATH and calcium carbonate, can replace resin content in sheet molding and bulk molding compounds. MoldX W300 is suited to color-sensitive applications, such as cast polymer and SMC and BMC.

Rampf PUs good for making soft castings
Rampf Group Inc. has added several polyurethanes for soft castings for electronic components.
The new Raku-Pur compounds are designed for a range of automotive applications such as sensors and circuit boards. The resins protect components from humidity, dust, chemicals and mechanical loads, the Wixom, Mich., company claims. The compounds also optimize insulation values and help dissipate heat.
The five new soft materials exhibit excellent temperature-cycling properties in the range of 58° F to 266° F. Resistance to vibrations ensures no crazing, even in thick-layered applications, according to Rampf. All the products have good adhesion in targeted end uses.

Nan-O-Sil powder reduces cycle time
Energy Strategy Associates Inc. has a new ultrafine, high-purity amorphous silica powder that can reduce cycle time in injection molding.
Nan-O-Sil is an effective processing aid for unfilled nylon 6, glass-filled nylon 6/6, ABS and polypropylene, according to Energy Strategy of Old Chatham, N.Y. In such resins it cuts cycle time by 20 to 30 percent. Other benefits include improved tensile strength, flexural modulus and color dispersion.
The high-purity colloidal silica is made through high-temperature hydrolysis in a hydrogen-oxygen flame. The discrete particles are spherical in shape and in a size range of about 0.02 to 0.55 microns.
