Glass-fiber reinforced nylon. When molded,Nylon 6/6 with 50, 60 and 70% glass
reinforcement yields high mechanical properties. The 60% glass-fiber-reinforced nylon has
a tensile strength of 33,000 psi, and the 70% glass-fiber-reinforced nylon offers a
flexural modulus value greater than 3 million psi. Glass-fiber concentrates yield greater
economy when blended with neat resin to produce reinforced nylon 6/6 composites containing
10 to 35% glass-fiber. When the concentrate is let down to the desired glass content, the
molded part offers properties suitable for existing automotive and appliance applications.

Composite molding compound technology. As a closed-molded system, sheet molding compound (SMC) characteristics are used for producing low-volume composite products. The system is used with polymer and other low-cost tooling alternatives at 100 psi, easily filling ribs and details using compression presses. Cure is at 200°F. This technology is easy to use and gives manufacturers an environmentally-friendly alternative to hand lay-up, spray-up, vacuum-bagging, RTM and cold molding. It significantly reduces tooling, presses and environmental emission equipment. Premix Inc, PO Box 281, Rt 20 & Harmon Rd, N Kingsville, OH 44068-0281. 440-224-2181. Circle606.
Melt processible rubber. The Alcryn product line exhibits better noise control properties and durability than either vulcanized rubber or thermoplastic rubbers for automotive parts used in applications under 125°C (257°F). Alcryn MPR (melt processible rubber) offers resistance to weathering, oil, fuel, and chemicals, and it can be processed by standard plastics machinery. Alcryn's itch noise performance is 2 to 5 times better than alternative flexible sealing materials. It does not require vulcanization, pre-drying, or any compounding prior to processing, and scrap can be recycled with no detrimental effect on performance. Alcryn bonds well to TPUs, copolyesters, and PC/ABS alloys without adhesives. Advanced Polymer Alloys, 3521 Silverside Rd, Quillen Building 2E, Wilmington, DE 19810. 302-478-8989. Circle 418. Non-silicone release liner. Non-silicone release is a solvent-based, thermally
cured wax chemistry. The coating is a fully reacted thermoplastic polymer that has a
melting point in the range of 85 to 95° C. The extremely thin, dry coating adds virtually
no additional haze to the base film, ensuring optically clear visual properties. They can
be used effectively with a variety of adhesives including natural rubber, SBR, Kraton and
acrylic. The liners are carefully produced to eliminate dust, debris or other
contamination that reduce performance. Applications include electronics and flexible
circuitry. Courtaulds Performance Films, PO Box 5968, Martinsville, VA

Copolymer. Grade K-Resin
styrene-butadiene copolymer is available for sheet extrusion to make single service
containers. K-resin XK40 SBC exhibits a high level of performance in blends with general
purpose polystyrene (GPPS). It allows an increased use of economical GPPS to make
end-products such as cups, lids and single service trays while maintaining the required
toughness and rigidity. Phillips Chemical Co, 821 South Johnstone Ave,
Bartlesville, OK 74004. 918-337-6600. Circle613.
Epoxy putty. Durabond 500°F epoxy
putty provides continuous high-temperature protection against corrosion, abrasion and
wear. The A54B and A54S are packaged in easy-to-use pre-measured kits. Mix to a uniform
color and apply and cure at room temperature to form a protective coating and durable
repairs. The putties are used for any manufacturing, production, industrial, or automotive
application. Cotronics Corp, 3379 Shore Parkway, Brooklyn, NY 11235.

Insulation core material. INSTILL
vacuum core is an insulating solution used as the core material in Vacuum Insulation
Panels (VIP). The open-cell, polystyrene foam enables significant design flexibility with
improved insulation performance and cost savings wherever a VIP is used to provide
thinner, more efficient insulation. It is used in refrigerators, freezers, insulated
shipping containers and refrigerated trucks. The Dow Chemical Co, PO Box
12061101, Midland, MI 48674-1206. 800-441-4369. 
Vinyl grips. Double-dipped grips
allow the mixing and matching of colors and materials to customize individual grip
applications. Durable, one-piece construction prevents these grips from ripping, tearing
or shredding when exposed to moisture or extreme conditions. The inner liner is
constructed of a durable material that goes on easy and stays put for a long-lasting hold.
The outer grip surface absorbs vibrations. Gripworks, 13515 Barrett Parkway
